Abstract

The invention discloses a method for rapidly judging stability of neutral high-fiber milk and belongs to the technical field of rapid dairy stability judgment. According to the method for rapidly judging the stability of the neutral high-fiber milk, the stability of the neutral high-fiber milk in shelf life is judged by measuring change conditions of viscosity, particles size and potential index before and after accelerated quality deterioration under constant temperature conditions of 4 DEG C, 25 DEG C, 37 DEG C and 50 DEG C. According to the method, the observation time of the stability of high-fiber milk products is greatly shortened, good or poor stability of the high-fiber milk products are basically judged within 10 days, the product development period is shortened, and the labor productivity is improved; the method has significance on developing products in dairy enterprises, and a gap of rapidly judging the stability of the neutral high-fiber milk is filled.

Description

technical field [0001] The present invention relates to a rapid determination method for the stability of neutral high-fiber milk, especially the use of particle size and potential analyzers to detect the change of value during short-term storage at a specific temperature, so as to determine the stability of product shelf life, which belongs to the stability of dairy products Quickly determine the technical field. Background technique [0002] Dietary fiber refers to the sum of edible plant ingredients, carbohydrates and similar substances that can resist digestion and absorption in the small intestine of the human body and can be partially or fully fermented in the large intestine of the human body. Including polysaccharides, oligosaccharides, lignin, and related plant substances, dietary fiber, known as the seventh largest nutrient, has been recognized by humans and plays an increasingly important role in dietary nutrition. [0003] Since 2011, more and more high-fiber mi...
