The following nonagricultural substances may be used as ingredients in or on processed products labeled as “organic” or “made with organic (specified ingredients or food group(s))” only in accordance with any restrictions specified in this section.
(a) Nonsynthetics allowed:
Acids (Citric - produced by microbial fermentation of carbohydrate substances; and Lactic).
Animal enzymes - (Rennet - animals derived; Catalase - bovine liver; Animal lipase; Pancreatin; Pepsin; and Trypsin).

Calcium sulfate - mined.
Diatomaceous earth - food filtering aid only.
Enzymes - must be derived from edible, nontoxic plants, nonpathogenic fungi, or nonpathogenic bacteria.
Flavors - nonsynthetic flavors may be used when organic flavors are not commercially available. All flavors must be derived from organic or nonsynthetic sources only and must not be produced using synthetic solvents and carrier systems or any artificial preservative.
Gellan gum (CAS # 71010-52-1) - high-acyl form only.
Glucono delta-lactone - production by the oxidation of D-glucose with bromine water is prohibited.

Magnesium sulfate, nonsynthetic sources only.
Microorganisms - any food grade bacteria, fungi, and other microorganism.
Nitrogen - oil-free grades.
Oxygen - oil-free grades.
Perlite - for use only as a filter aid in food processing.
Tartaric acid - made from grape wine.
Waxes - nonsynthetic (Wood resin).
Yeast - When used as food or a fermentation agent in products labeled as “organic,” yeast must be organic if its end use is for human consumption; nonorganic yeast may be used when organic yeast is not commercially available. Growth on petrochemical substrate and sulfite waste liquor is prohibited. For smoked yeast, nonsynthetic smoke flavoring process must be documented.
(b) Synthetics allowed:
Acidified sodium chlorite - Secondary direct antimicrobial food treatment and indirect food contact surface sanitizing. Acidified with citric acid only.
Activated charcoal (CAS #s 7440-44-0; 64365-11-3) - only from vegetative sources; for use only as a filtering aid.
Alginic acid (CAS #9005-32-7)
Ammonium bicarbonate - for use only as a leavening agent.
Ammonium carbonate - for use only as a leavening agent.
Calcium phosphates (monobasic, dibasic, and tribasic).
Cellulose (CAS #9004-34-6) - for use in regenerative casings, powdered cellulose as an anti-caking agent (non-chlorine bleached) and filtering aid. Microcrystalline cellulose is prohibited.
Chlorine materials - disinfecting and sanitizing food contact surfaces, equipment and facilities may be used up to maximum labeled rates. Chlorine materials in water used in direct crop or food contact are permitted at levels approved by the FDA or EPA for such purpose, provided the use is followed by a rinse with potable water at or below the maximum residual disinfectant limit for the chlorine material under the Safe Drinking Water Act. Chlorine in water used as an ingredient in organic food handling must not exceed the maximum residual disinfectant limit for the chlorine material under the Safe Drinking Water Act.
i. Calcium hypochlorite.
ii. Chlorine dioxide.
iii. Hypochlorous acid - generated from electrolyzed water.
iv. Sodium hypochlorite.
Ethylene - allowed for postharvest ripening of tropical fruit and degreening of citrus.
Ferrous sulfate - for iron enrichment or fortification of foods when required by regulation or recommended (independent organization).
Glycerides (mono and di) - for use only in drum drying of food.
Magnesium stearate - for use only in agricultural products labeled “made with organic (specified ingredients or food group(s)),” prohibited in agricultural products labeled “organic”.
Nutrient vitamins and minerals, in accordance with 21 CFR 104.20, Nutritional Quality Guidelines For Foods.
Peracetic acid/Peroxyacetic acid (CAS # 79-21-0) - for use in wash and/or rinse water according to FDA limitations. For use as a sanitizer on food contact surfaces.
Phosphoric acid - cleaning of food-contact surfaces and equipment only.
Potassium hydroxide - prohibited for use in lye peeling of fruits and vegetables except when used for peeling peaches.
Potassium lactate - for use as an antimicrobial agent and pH regulator only.
Potassium phosphate - for use only in agricultural products labeled “made with organic (specific ingredients or food group(s)),” prohibited in agricultural products labeled “organic”.
Silicon dioxide - Permitted as a defoamer. Allowed for other uses when organic rice hulls are not commercially available.
