Section 2783.5 - Fats and Oils

(a) General Provisions: Any mixture of two or more fats or fat derivatives defined below shall be identified by listing each component, for example, "animal fat and hydrolyzed vegetable oil." Any antioxidant used shall be named and followed by the word "preservative." All fats and oils used in commercial feed shall be pathogen free and safe for use as animal feed. The percentage of fatty matter is the total percentage of moisture, insoluble matter and unsaponifiable matter subtracted from 100. The use of sewer plant fats and oils is prohibited.

(b) Animal Fat is obtained from the tissues of mammals and/or poultry in the commercial processes of rendering or extracting. It consists predominantly of glyceride esters of fatty acids and contains no additions of free fatty acids or other materials obtained from fats. It must contain, and be guaranteed for, not less than 90 percent total fatty acids, not more than 2.0 percent unsaponifiable matter, and not more than 1.0 percent insoluble impurities. Maximum free fatty acids and moisture must also be guaranteed. If the product bears a name descriptive of its kind or origin; i.e., "beef", "pork", "poultry", it must correspond thereto. If an antioxidant is used, the common name or names shall be indicated, followed by the words "used as a preservative".

(c) Fat Product, Feed Grade is any fat product which does not meet the definitions for animal fat, vegetable fat or oil, hydrolyzed fat or fat ester. It shall be sold on its individual specifications which will include the minimum percentage of total fatty acids, the maximum percentage of unsaponifiable matter, the maximum percentage of insoluble impurities, the maximum percentage of free fatty acids and moisture. The above listed specifications shall be guaranteed on the label. If an antioxidant(s) is used, the common name or names shall be indicated, followed by the words "used as a preservative".

(d) Vegetable Fat or Oil is the product of vegetable origin obtained by extracting the oil from seeds or fruits which are commonly processed for edible purposes. It consists predominantly of glyceride esters of fatty acids, and contains no additions of free fatty acids, or other materials obtained from fats. It shall contain and be guaranteed for not less than 90 percent total fatty acids, not more than 2.0 percent unsaponifiable matter and not more than 1.0 percent insoluble impurities. Maximum percent free fatty acids, and moisture shall also be guaranteed. If the product bears a name descriptive of its kind or origin, i.e., "soybean oil", "cottonseed oil", it shall correspond thereto. If an antioxidant(s) is used, the common name or names shall be indicated, followed by the words "used as a preservative".

(e) Hydrolyzed Fat or Oil (feed grade) is a product obtained by the fat processing procedures commonly used in edible fat processing or soap making. It consists predominantly of fatty acids, and shall contain, and be guaranteed for, not less than 85.0 percent total fatty acids, not more than 6.0 percent unsaponifiable matter, and not more than one (1) percent insoluble impurities. Maximum moisture must also be guaranteed. Its source shall be stated in the product name, i.e., "hydrolyzed animal fat," "hydrolyzed vegetable," "hydrolyzed animal and vegetable fat." If an antioxidant(s) is used, the common name or names must be indicated, followed by the words "used as a preservative".

(f) Ester (feed grade) is the product consisting of methyl, ethyl or other nonglyceride ester of fatty acids derived from animal and/or vegetable fats. It consists predominantly of the ester and shall contain not less than 85.0 percent total fatty acids, not more than 10.0 percent free fatty acids, not more than 6.0 percent unsaponifiable matter, (2.0 percent for methyl esters), and not more than 1.0 percent insoluble matter. Its source shall be stated in the product name, i.e., "methyl ester of animal fatty acids," "ethyl ester of vegetable oil fatty acids." Methyl esters shall contain not more that 150.0 parts per million (0.015 percent) free methyl alcohol. If an antioxidant(s) is used, the common name or names must be indicated, followed by the word "preservative(s)".

(g) Corn Endosperm Oil is obtained by the extraction of oil from corn gluten. It consists predominantly of free fatty acids and glyceride, and shall contain not less than 85.0 percent total fatty acids, not more than 14.0 percent unsaponifiable matter, and not more than 1.0 percent insoluble matter. if an antioxidant(s) is used, the common name or names shall be indicated followed by the word "preservatives".

(h) Corn Syrup Refinery Insolubles, Feed Grade is obtained in the refining of a corn syrup. It consists predominantly of the fatty fraction of corn starch together with protein and residual carbohydrate. It may contain water and not more than 7.0 percent ash nor less than 50.0 percent fat on a water-free basis.

(i) Calcium Salts of Long-Chain Fatty Acids are the reaction products between calcium and long-chain fatty acids of vegetable and/or animal origin. They shall contain a maximum of 20.0 percent lipid not bound in the calcium salt form and percent total fat shall be indicated. The unsaponifiable matter (exclusive of calcium salts) shall not exceed 4.0 percent and moisture shall not exceed 5.0 percent. If an antioxidant(s) is used, its common name(s) must be indicated on the label. Prior to conducting an assay for total fats, hydrolysis of the calcium salts should be performed to liberate the lipid fraction.

(j) Hydrolyzed Sucrose Polyesters, Feed Grade is the product resulting from the acid hydrolysis of sucrose polyesters, such as olestra, to make them digestible. It shall consist predominately of fatty acids and contain, and be guaranteed for, not less than 85.0 percent total fatty acids, not more than 2.0 percent Sucrose Polyesters (hex ester and above), not more than 2.0 percent unsaponifiable matter, and not more than 2.0 percent insoluble impurities. Maximum moisture shall also be guaranteed. Its source shall be stated in the product name, i.e., "Hydrolyzed animal sucrose polyesters", "Hydrolyzed vegetable sucrose polyesters", or "Hydrolyzed animal and vegetable sucrose polyesters". If an antioxidant(s) is used, the common name or names shall be indicated, followed by the words "used as a preservative".

(k) Vegetable Oil Refinery Lipid, Feed Grade, is obtained in the alkaline refining of a vegetable oil for edible use. It consists predominantly of the salts of fatty acids, glyceride, and phosphates. It may contain water and not more than 22.0 percent ash on a water-free basis. It may or may not be acidulated before using in commercial feeds, but if acidulated, it shall be neutralized.
