QUANTITATIVE FOOD PROTEINS CONTENT DETERMINATION METHOD |
摘要 |
FIELD: food industry.SUBSTANCE: quantitative food proteins content determination method involves the following operations, sequentially performed: mixing test samples of the substrate and a fermentative substance coupled with a stabilising solution, incubation of the produced mixture at a temperature of 37°C, centrifugation of the fermentative-and-substrate complex and determination of quantitative food proteins content by way of calculation. The fermentative substance is represented by pancreatic juice preliminarily diluted with a stabilising solution down to 50% concentration, the ratio of the solution to the substrate test sample weight equal to 1:10. The prepared mixture incubation is performed during 5-15 minutes. Before quantitative food proteins content determination by way of calculation, the pure liquid fraction volume produced as a result of centrifugation is diluted with the stabilising solution at a ratio of 1:100-200. The food protein quantity is determined as equal to percentage expenditure of protease enzymes in comparison with a reference sample of pancreatic juice solution.EFFECT: enhanced accuracy of determination of the quantitative food proteins content in food products.3 tbl |
