Abstract

The invention discloses additive-free yogurt. The yogurt comprises, by mass 3.8-5.0wt% of protein, 4.0-5.5wt% of fat, 15-20wt% of total solids and 10-15wt% of non-fat milk solids, has a titratable acidity of 70-80 DEG, and the percentages are mass percentages relative to the additive-free yogurt. Raw materials of the additive-free yogurt comprises, by 1000 parts, 499.9-919.99 parts of raw milk, 80-500 parts of concentrated milk and 0.01-0.1 part of fermented culture, wherein the milk solid content of the concentrated milk is 30-60wt%, and the percentage is a mass percentage relative to the concentrated milk. The additive-free yogurt may be stirred yogurt or set yogurt. The invention also discloses a preparation method of the additive-free yogurt. The additive-free yogurt can still maintain good quality and taste with no additives, is full of nutriments, and can keep a good stability during storing, conveying and selling processes without precipitation of whey.

Description

technical field [0001] The invention belongs to the field of dairy product production, in particular to a yoghurt without additives and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of social economy and the high progress of science and technology, more and more food additives have been developed and widely used. At the same time, food safety incidents caused by the use of food additives are not uncommon, and have become a topic of divergent opinions and continuous attention recently. Food additives are different from food nutrition fortifiers, and generally do not have nutritional ingredients and nutritional value. my country's "Food Safety Law of the People's Republic of China" implemented on June 1, 2009 has a clear definition of food additives, which refers to food additives that are used to improve food quality, color, aroma, and taste, as well as to meet the needs of antisepsis, freshness preservation, and proc...
