Requirements for raw materials Not to be detected 6.1 In addition to complying with the GB1533 standard, the raw materials shall also meet the following requirements. 10.10 6.1.1 For general peanut cake raw materials and first-grade highly modified peanut meal, the residual rate of raw material red skin shall be less than 15%. 6.1.2 For first-grade low-modified peanut meal, the residual rate of raw material red skin shall be less than 10%. For second-grade low-modified peanuts, the residual rate of raw material red skin shall be less than 15%. For third-grade low-modified peanut meal, the residual rate of raw material red skin shall be less than 20%. 6.1.3 No poisonous weed seeds shall be mixed in. 6.1.4 There shall be no spoiled contaminated particles and no peculiar smell. 6.1.5 There shall be no other substances that cannot be removed during processing. 7 Testing methods The sampling and analysis of edible peanut cakes shall be carried out in accordance with GB5490 and GB10360. 7.1 7.2 The identification of color and smell shall be carried out in accordance with GB5492. 7.3 The determination of moisture shall be carried out in accordance with GB10358. 7.4 The determination of crude protein shall be carried out in accordance with GB9823. 7.5 The determination of water-soluble protein shall be carried out in accordance with Appendix A of GB5511. 7.6 Calculation of nitrogen solubility index (NSI,%): N1 NSI(%)= NSI(%)= Wherein: N1- water-soluble nitrogen, g; total nitrogen in sample, g; -×100 Nwater-water-soluble protein, g; Ncrude-crude protein, g. 7.7 The determination of crude fat shall be carried out in accordance with GB10359. 7.8 The determination of crude cellulose shall be carried out in accordance with GB5515. 7.9 The determination of ash shall be carried out in accordance with GB9824. 7.10 The determination of sand content shall be carried out in accordance with GB9825. 7.11 The determination of impurities shall be carried out in accordance with Appendix A of this standard. 7.12 The determination of red clothing residue rate shall be carried out in accordance with Appendix B of this standard. 7.13 The determination of sanitary indicators shall be carried out in accordance with the relevant national grain and oil sanitary inspection methods. 8 Packaging, transportation and storage 8.1 Packaging: The sacks used for large packaging shall be implemented in accordance with GB8115.

Appendix A Determination of impurities in peanut cake and meal (Supplement) A1 Instruments and utensils A1.1 Balance, sensitivity 0.5g, 0.01g A1.2 Sample divider and sample dividing plate A1.3 Analysis plate A1.4 Tweezers A2 Sample preparation: Use appropriate methods to break the sample so that the maximum length of one dimension of the particles does not exceed 20mm. A3 Operation method Use the quartering method to take out two average samples of about 1000g each. Weigh (accurate to 0.5g) and spread them evenly on the analysis plate. Use tweezers to wipe out the non-peanut cake and meal substances and peanut cake and meal without edible value, and weigh them again (accurate to 0.01g). A4 Result Calculation —×100 Impurity (%)=bzxZ.net Impurity weight, g; Where: W1- W2—sample weight, g The allowable error of the double test results shall not exceed 0.2%. The average value is the measurement result.The determination result shall be rounded to two decimal places. Appendix B Determination of residual red skin rate of peanut kernels (Supplement) B1 Instruments and appliances B1.1 Balance, sensitivity 0.5g, 0.01g B1.2 Sample plate B2 Operation method Take about 500g of peanut kernels before and after removing the red skin from the same batch, place them in an electric heating box preheated to 105℃±2℃, bake for about 1h, take them out, cool them to room temperature, weigh out 200g (accurate to 0.5g) respectively, rub off the red skin or the remaining red skin with your fingers, and weigh the rubbed red skin separately (accurate to 0.01g). B3 Result calculation Red skin residual rate (%)= Wherein: W1—weight of red skin remaining on peanut kernel after removing red skin, g; W——weight of red skin on peanut kernel before removing red skin, g. The allowable error of double test results shall not exceed 1%, and the average value shall be the measurement result.
