Step 1 of 8 · Beverage Production
Water treatment & liquor prep
Water is more than ninety percent of most beverages. Every flavor decision downstream is built on top of whatever the water is doing.
What goes wrong hereChlorine or chloramine surviving into the syrup room. It shows up as a plastic or medicinal note that no amount of flavor adjustment will cover.
What gets used and why
- Granular activated carbonChlorine, chloramine, and organic off-flavor removal. The single most important treatment step for taste consistency.
- Sodium metabisulfiteDechlorination ahead of membranes, since residual chlorine destroys polyamide RO elements permanently.
- AntiscalantsHold hardness and silica in solution so RO recovery can run where the economics need it.
- Softener saltIon exchange regeneration, consumed continuously and usually bought on the loosest specification in the plant.
- Calcium chloride and mineral saltsRemineralization after RO, rebuilding the mouthfeel and flavor profile the brand standard requires.

Step 2 of 8 · Beverage Production
Syrup room & acidulation
The acid system sets tartness, sets pH, and sets the microbial hurdle that everything downstream depends on.
What goes wrong hereAn acid that arrives off specification changes titratable acidity, and the whole batch reads wrong at QC even though every other ingredient was correct.
What gets used and why
- Citric acid anhydrous and monohydrateThe dominant beverage acidulant. Clean bright tartness, and hydrate form matters for both dosing math and caking behavior.
- Phosphoric acidThe characteristic sharper, flatter acidity of cola. Not interchangeable with citric on flavor.
- Malic and fumaric acidLingering tartness for fruit profiles, and fumaric for low solubility slow release applications.
- Sodium and potassium citrateBuffering that holds pH steady as other ingredients are added, protecting flavor consistency.
- Gum arabicEmulsion stability for flavor oils in the finished syrup.

Step 3 of 8 · Beverage Production
Preservation & stabilization
The microbial hurdle system. Low pH does most of the work, and preservatives cover what pH alone cannot.
What goes wrong hereSpoilage yeast in a low acid or reduced sugar product, which appears as a swollen package on a retail shelf months after production.
What gets used and why
- Potassium sorbateYeast and mold inhibition. More soluble than sorbic acid, which is why it dominates in liquid systems.
- Sodium benzoateEffective below pH 4.5 and inexpensive. Requires care alongside ascorbic acid due to benzene formation chemistry.
- Dimethyl dicarbonateCold sterilant dosed at the filler, hydrolyzing completely so it does not appear on the label as a preservative.
- Calcium disodium EDTAChelates trace metals that would otherwise drive flavor and color degradation over shelf life.
- Ascorbic acidAntioxidant and oxygen scavenger, protecting both flavor and vitamin claims.
5 raw materials at this step
Step 4 of 8 · Beverage Production
Clouding, color & mouthfeel
The visual and tactile part of the product, which consumers judge before they ever taste it.
What goes wrong hereRing formation at the neck, or a cloud emulsion that separates before end of shelf life, both of which read as a spoiled product.
What gets used and why
- Gum arabicEmulsifier and weighting system for flavor oil emulsions in citrus beverages.
- Xanthan gum and pectinMouthfeel and suspension in juice, dairy alternative, and reduced sugar products.
- Calcium carbonateOpacity and clouding agent, increasingly specified as a titanium dioxide replacement.
- Caramel color and natural colorsVisual identity, with acid stability being the practical selection criterion.
- Carboxymethyl celluloseBody and suspension in low sugar formulations that lost their mouthfeel with the sugar.

Step 5 of 8 · Beverage Production
Carbonation & gas handling
Dissolved gas is a flavor component, a preservation hurdle, and a filling problem all at once.
What goes wrong hereFoaming at the filler cuts line speed directly, and every percent of downtime here is measured against a filler that cost millions.
What gets used and why
- Food grade carbon dioxideCarbonation and counter pressure, on a specification that covers trace impurities capable of tainting product.
- NitrogenNitrogen dosing for still products in lightweight containers, plus nitro dispense applications.
- Food grade antifoamFiller bowl foam control where formulation and CO2 fight each other.
- Deaeration chemistryDissolved oxygen removal ahead of carbonation, protecting shelf life and carbonation efficiency.

Step 6 of 8 · Beverage Production
Filtration & clarification
Removing haze, particulates, and the precursors that would become haze months later in the bottle.
What goes wrong hereA product that is brilliantly clear at filling and hazy at the retailer, because the haze precursors were never removed, only not yet visible.
What gets used and why
- Diatomaceous earth and perliteBody feed and precoat filtration, the volume workhorses of beverage clarification.
- PolyvinylpolypyrrolidonePolyphenol removal, targeting the haze precursors rather than the haze itself.
- BentoniteProtein removal and colloidal stabilization, particularly in juice and wine.
- Silica solFining agent working with bentonite and gelatin systems.

Step 7 of 8 · Beverage Production
Filling & packaging
The last point where contamination can enter, and the fastest moving part of the plant.
What goes wrong hereA container rinse or cap sanitizer failure, which is invisible at the time and becomes a hold on everything produced since the last verified check.
What gets used and why
- Peracetic acidContainer and closure sanitizing, no rinse required and effective at cold fill temperatures.
- Conveyor lubricantsDry film silicone and soap based wet systems. Container material and floor safety both drive the choice.
- Food grade antifoamFiller bowl and vacuum system foam control at line speed.
- Bottle rinse water treatmentRinse water quality, since rinse water residue becomes product contamination.
- Coding and marking solventsDate and lot coding, where legibility is a regulatory requirement.
5 raw materials at this step
Step 8 of 8 · Beverage Production
Line CIP & changeover
Between products, between allergens, and at end of run. The step that protects everything the plant made that day.
What goes wrong hereAn incomplete changeover carrying allergen or flavor residue into the next product, which is a recall rather than a quality complaint.
What gets used and why
- Caustic sodaAlkaline cycle removing organic soil, sugar residue, and flavor carryover.
- Nitric and phosphoric acidAcid cycle removing mineral scale and passivating stainless surfaces.
- Chlorinated alkaline cleanersAdded oxidation for protein and stubborn flavor residue.
- Low foam surfactantsSoil suspension in recirculating loops without foaming the CIP pump.
- ChelantsHard water tolerance so detergent works on soil rather than on the water.
- Peracetic acidFinal no-rinse sanitizing before the line restarts.

Step 1 of 7 · Brewing and Distilling
Brewing liquor treatment
Brewers do not treat water, they build it. Salt additions target a specific ion profile matched to the style being brewed.
What goes wrong hereChloramine surviving into the mash reacts with phenols from the malt and produces a chlorophenol note detectable at parts per billion.
What gets used and why
- Calcium sulfateGypsum. Delivers sulfate, which accentuates hop bitterness and gives a drier finish.
- Calcium chlorideDelivers chloride, which rounds the palate and accentuates malt character. The other half of the brewer's balance.
- Sodium metabisulfiteChloramine destruction, which carbon filtration alone does not fully accomplish.
- Lactic and phosphoric acidMash and sparge water pH correction to the enzymatic optimum.
- Granular activated carbonChlorine and organic off-flavor removal ahead of the brewhouse.
5 raw materials at this step
Step 2 of 7 · Brewing and Distilling
Mashing & enzymes
Converting starch to fermentable sugar, where pH and calcium determine whether the enzymes work at the rate the schedule assumes.
What goes wrong hereA mash pH slightly high, which lowers extract efficiency and shifts the entire fermentation profile before anyone has tasted anything.
What gets used and why
- Alpha amylase and glucoamylaseSupplemental enzymes for adjunct brewing, high gravity work, and highly attenuated products.
- Calcium saltsEnzyme stabilization and pH buffering in the mash.
- Lactic acidDirect mash pH adjustment where acidulated malt is not used.
- Beta glucanaseViscosity reduction improving lauter runoff on problem grists.

Step 3 of 7 · Brewing and Distilling
Boil, wort & kettle additions
Hot break formation, sterilization, and hop utilization, all with a foam problem on top.
What goes wrong hereA kettle boilover, which is lost product, lost time, and a cleaning job nobody wants.
What gets used and why
- Carrageenan kettle finingsHot break protein coagulation, giving brighter wort into the fermenter.
- Zinc saltsYeast nutrient. Wort is often zinc deficient, and zinc deficiency shows up as a sluggish fermentation.
- Food grade silicone antifoamBoil and fermentation foam control, permitting higher fill and preventing boilover.
- Calcium saltsKettle pH adjustment and hot break improvement.
4 raw materials at this step
Step 4 of 7 · Brewing and Distilling
Fermentation
The biological step, where nutrient status and oxygen management determine whether the flavor profile matches the last batch.

What gets used and why
- Diammonium phosphateFree amino nitrogen supplementation, especially in high gravity and adjunct heavy worts.
- Zinc and thiamine blendsMicronutrients addressing the specific deficiencies that cause sluggish fermentations.
- Food grade antifoamFermenter foam control, which directly increases usable vessel capacity.
- Food grade carbon dioxide and nitrogenPurging, counter pressure, and oxygen exclusion through transfers.

Step 5 of 7 · Brewing and Distilling
Filtration, stabilization & clarity
Removing what would become haze, and protecting flavor from oxidation over the shelf life the brand promises.
What goes wrong hereChill haze appearing in a cold retail cooler, which the consumer reads as spoilage regardless of what the product tastes like.
What gets used and why
- PolyvinylpolypyrrolidonePolyphenol removal for permanent chill haze prevention. Regenerable, which changes the cost calculation.
- Silica gel and xerogelHaze active protein removal, the other half of the haze pair, without stripping foam protein.
- Diatomaceous earth and perliteFiltration media for clarity ahead of packaging.
- Ascorbic acid and metabisulfiteOxygen and staling control, protecting flavor stability through distribution.
- Propylene glycol alginateFoam stability in the finished glass, which is how a lot of consumers judge quality.
5 raw materials at this step
Step 6 of 7 · Brewing and Distilling
Distilling & spirits
Fermentation at scale followed by separation, where the still is both the product step and the biggest cleaning problem.
What goes wrong hereScale on still heating surfaces reducing heat transfer, plus congener carryover that shows up as an off note in the finished spirit.
What gets used and why
- Sulfuric and phosphoric acidMash pH control at fermentation scale, and acid cleaning of still surfaces.
- Yeast nutrient blendsNitrogen and micronutrient supplementation in grain and molasses fermentations.

Step 7 of 7 · Brewing and Distilling
Brewery CIP & keg wash
Tank, line, and keg cleaning, which in a brewery is a bigger chemical spend than most of the ingredients.
What goes wrong hereBeer stone, a calcium oxalate and protein deposit that alkaline cleaning alone will not remove and that harbors spoilage organisms.
What gets used and why
- Caustic soda with additivesPrimary alkaline cycle on tanks and lines, formulated with chelants and surfactants for beer soil.
- Nitric and phosphoric acidBeer stone removal and stainless passivation, the cycle most often skipped and most needed.

Step 1 of 7 · Dairy Processing
Raw milk receiving & tanker wash
The first control point. Everything that arrives becomes the plant's problem, including whatever was in the tanker.
What goes wrong hereA tanker that was not properly washed, seeding the silo with spoilage organisms before the milk has been in the building an hour.
What gets used and why
- Chlorinated alkaline cleanersTanker and silo cleaning, removing milk protein and fat film.
- Phosphoric and nitric acidAcid cycle removing milkstone from tankers, silos, and receiving lines.
- Peracetic acidNo rinse sanitizing before the next load.
- Low foam surfactantsSoil suspension in spray ball and recirculating wash systems.

5 raw materials at this step
Step 2 of 7 · Dairy Processing
Separation, standardization & pasteurization
Heat treatment on plate heat exchangers, where milk protein and minerals bake onto the plates a little more with every hour of run time.

Step 3 of 7 · Dairy Processing
Cheese making
Coagulation, cutting, and draining, where a small chemistry change moves yield by a percentage the plant feels immediately.
What goes wrong hereWeak curd from pasteurized milk that lost soluble calcium to heat treatment, producing fines loss into the whey and a direct yield hit.
What gets used and why
- Calcium chlorideRestores soluble calcium lost during pasteurization, giving firmer curd and measurably better yield.
- Citric and lactic acidDirect acidification for fresh cheeses where culture is not used.
- Sodium chlorideSalting for flavor, moisture control, and microbial hurdle. Very large volume in a cheese plant.

5 raw materials at this step
Step 5 of 7 · Dairy Processing
Evaporation, drying & powder
Concentrating and spray drying, the most fouling intensive and energy intensive part of a dairy plant.
What goes wrong hereBurn-on in the evaporator, which shortens the run, costs a long cleaning cycle, and can put scorched particles into the powder.
What gets used and why
- Caustic sodaHeavy duty alkaline cleaning of evaporators and dryers, the largest single chemical volume in most dairy plants.
- Nitric acidMineral scale removal on evaporator heat transfer surfaces.
- AntifoamFoam control in evaporator bodies and balance tanks, where carryover contaminates the condensate.
- LecithinInstantizing agent giving powder its wettability and dispersion in cold water.

5 raw materials at this step
Step 6 of 7 · Dairy Processing
Process cheese & emulsifying salts
Converting natural cheese into a stable, sliceable, meltable product, which is entirely an emulsifying salt problem.
What goes wrong hereFat separation or an oily surface, which happens when the emulsifying salt system does not match the cheese age and calcium level.
What gets used and why
- Disodium phosphateThe standard emulsifying salt, sequestering calcium so casein can emulsify the fat.
- Trisodium citrateEmulsifying salt giving a softer body and a different melt profile.
- Sodium hexametaphosphateStrong calcium sequestration for firm, sliceable products.
- Sorbic acid and potassium sorbateMold control in packaged process cheese.
- Sodium chlorideFlavor and preservation contribution.

Step 7 of 7 · Dairy Processing
Dairy plant CIP & membranes
The cleaning program that a dairy plant lives or dies on, including membrane systems that will not tolerate conventional chemistry.
What goes wrong hereA membrane plant cleaned with the wrong chemistry or the wrong temperature, which is a six figure element replacement rather than a cleaning failure.
What gets used and why
- Caustic sodaAlkaline cycle across tanks, lines, and equipment.
- Nitric and phosphoric acidMilkstone removal and passivation on all product contact surfaces.
- Chlorinated alkaline cleanersProtein film removal where chlorine is compatible with the equipment.

Step 1 of 8 · Food Processing
Produce wash & raw material prep
The first intervention step, and on fresh and minimally processed product it is often the only kill step there is.
What goes wrong hereCross contamination in the wash tank, where one contaminated lot seeds an entire day of production through recirculated water.

Step 2 of 8 · Food Processing
Blanching, peeling & processing aids
Thermal and chemical preparation, where enzymatic browning starts the moment the product is cut.

Step 3 of 8 · Food Processing
Formulation & pH control
Where the recipe is built, and where pH becomes the primary food safety control for most shelf stable products.
What goes wrong hereA finished pH above 4.6, which moves the product from acidified into low acid and changes the entire regulatory and thermal process picture.
What gets used and why
- Citric acidThe general purpose acidulant across nearly every food category.
- Acetic acid and vinegarSharp acidity plus antimicrobial contribution in dressings, sauces, and pickles.
- Lactic acidMilder acidity with strong antimicrobial performance, widely used in meat and ready meals.
- Phosphoric acidSharp acidification where a flat acid profile suits the product.
- Sodium and potassium hydroxideUpward pH correction and neutralization.

Step 4 of 8 · Food Processing
Preservation & shelf life
The hurdle system protecting the product from the moment it is packaged until the date on the label.
What goes wrong hereMold on a bakery product two days before the coded date, which is a customer complaint, a credit, and a lost shelf position.
What gets used and why
- Potassium sorbateBroad yeast and mold inhibition across acidified foods.
- Sodium benzoateCost effective preservation below pH 4.5.
- Calcium propionateThe bakery standard for mold inhibition without inhibiting yeast leavening.

What gets used and why
- Ascorbic acid and sodium erythorbateOxygen scavenging and color protection, especially in meat and beverage.
- Mixed tocopherolsNatural antioxidant for fats and oils, supporting clean label positioning.
- Rosemary extractNatural antioxidant with strong performance in high fat systems.

The kill step, and the point where water chemistry touches food safety through the container rather than through the recipe.
What goes wrong hereContainer corrosion or a can cooling water failure, where a microleak past the seam during cooling defeats a perfectly executed thermal process.
What gets used and why
- Can cooling water sanitizerChlorine or equivalent in cooling water, since the container breathes as it cools and pulls water past the seam.
- Corrosion inhibitorsProtect containers and retort equipment in a hot, wet, and chemically aggressive environment.

Step 1 of 7 · Sanitation and Utilities
CIP program design
The recirculating clean that never sees an operator's hands, which means the chemistry and the parameters are the entire control.

Step 3 of 7 · Sanitation and Utilities
Sanitizing & no-rinse
The final step before production, applied to a surface that is already clean, because sanitizer on soil does nothing.

The utility side, with one constraint that does not exist in any other industry: steam that contacts food restricts what can be in the boiler.
What goes wrong hereA boiler treatment chemical that is perfectly standard everywhere else and not permitted where the steam contacts food.
What gets used and why
- Approved boiler treatment compoundsSteam in food contact restricts treatment to specifically permitted chemistry, which narrows the options considerably.

Or start with the problem
Nobody calls about chemistry. They call about a hold.
The call is never a request for trisodium citrate. It is a microbial positive, a separated product, a swollen package, or an evaporator that will not stay clean. Pick what you are seeing and the steps that address it will light up across every route.
Select a problem to highlight the relevant process steps in every route.
How Lowe helps
Two things get people in trouble here. Grade and paperwork.
Food grade, FCC, USP, and technical are four different products wearing the same chemical name, and substituting down to save money works until an auditor asks for the certificate you do not have. The second trap is documentation that cannot be created after the fact. Kosher and halal certification, allergen and origin statements, and lot traceability all have to be in place before the lot ships, not after it arrives.
1
Tell us the step and the gradeWhere it goes in the process, the grade or compendial standard, certifications required, package size, volume, and destination.2
We check the sourcing pathAvailability at that grade, supplier fit, COA and certification review, lot traceability, and practical alternates when a grade runs tight.3
You get a clear answerA quote, a sample for qualification, or a straight explanation of what is realistic. No runaround either way.
Ask about documentation before the first order, not after it lands.
Some certifications cannot be generated retroactively for a lot that has already shipped. If your quality system needs a kosher certificate, an allergen statement, a country of origin declaration, or a specific compendial COA, tell us at the quote stage and we will confirm it is available on that exact material before anything moves.
