This standard is developed in accordance with the rules given in GB/T 1.1-2009.
This standard supersedes GB/T 19541-2004 Soybean Meal (Solvent) for Feedstuff. In addition to editorial changes, the following technical changes have been made with respect to GB/T 19541-2004:
——the standard title is revised as Feed Materials—Soybean Meal;
——'Scope' is modified (see Chapter 1);
——'Normative References' is modified (see Chapter 2);
——in sensory properties, fawn and caking is deleted, while maple or sorrel and coarse particle type are added (see 4.1);
——the inclusion indexes are deleted (see 4.2 of Edition 2004);
——the quality grade indexes are modified (see 4.2);
——the net content requirements are added (see 4.4);
——the inclusion inspection is deleted (see 5.1 of Edition 2004);
——the inspection of sensory properties and urease activity is modified (see 5.1 and 5.7);
——the inspection of lysine, hygienic index and net content is added (see 5.6, 5.9 and 5.10);
——the method for determination of protein solubility in potassium-hydroxide solution is adjusted to Annex A (see 5.8);
——the permissible errors in test method and monitoring and arbitration requirements are deleted (see 5.8 and 5.9 of Edition 2004);
——the inspection rules are modified (see Chapter 6);
——the soybean meal produced with transgenic soybean is added which shall be in accordance with the requirements of Measures for Management of Labelling for Agricultural Genetically Modified Organisms (see 7.1);
——the determination of protein solubility in potassium-hydroxide solution is modified (see Annex A).
This standard was proposed by and is under the jurisdiction of the National Technical Committee on Feed Industry of Standardization Administration of China (SAC/TC 76).
The previous editions of the standard superseded by this standard are as follows:
——GB/T 10380-1989, GB/T 19541-2004.
Feed Materials—Soybean Meal
1 Scope
This standard specifies the relevant terms and definitions, requirements, test methods, inspection rules, labelling, packaging, transportation and storage of soybean meal for feed materials.
This standard is applicable to soybean meal for feed materials produced with soybean after oil extraction by prepressing extraction or direct solvent extraction, or with soybean cake after oil extraction, or with soybean germ after oil extraction by expansion extraction.
