Abstract

The invention discloses health-caring walnut sour-milk and a preparation method thereof. The health-caring walnut sour-milk is prepared from the following raw materials: walnut kernels, milk powder, oat flour, bran powder, buckwheat flour, corn oligopeptides, carrot powder, pumpkin powder, white granulated sugar, sugar alcohol, oligosaccharides, lily bulb powder, and honeysuckle flower powder. Thepreparation method of the health-caring walnut sour-milk comprises the following steps: A, performing pretreatment on raw materials, namely preparing walnut milk from carefully selected high-qualitywalnuts; B, blending raw-material milk and carrying out homogenization, namely adding other ingredients into the walnut milk, carrying out stirring so as to have the raw-material milk uniformly mixed,and carrying out homogenization for two times; C, carrying out sterilizing and cooling; D, carrying out inoculation and fermentation, namely adding domesticated sour milk fermentation agent into thesterilized and cooled milk liquid, wherein the addition amount of the domesticated sour milk fermentation agent in mass ratio is 2.5-3.5%, and carrying out fermentation at 42-44 DEG C for 5-7 hours; and E, carrying out refrigerated post-ripening, namely rapidly taking the fermented sour milk out after completion of the fermentation, and carrying out cooling. By adding a plurality of dietary fibers, the health-caring walnut sour-milk disclosed by the invention has significant health-caring functions; moreover, no preservative is added during the preparation process, so that, the health-caring walnut sour-milk is a natural nutritious health-caring food. And thus, the concept for healthy life of the modern people is met.

Description

technical field [0001] The invention relates to walnut health-care yoghurt and a preparation method thereof, belonging to the technical field of food processing. Background technique [0002] Walnuts are rich in nutritional value and have the reputation of "longevity fruit", "longevity fruit" and "health treasure". 86% of the fat in walnuts is unsaturated fatty acids. Walnuts are rich in copper, magnesium, potassium, vitamin B6, folic acid and vitamin B1. They also contain fiber, phosphorus, niacin, iron, vitamin B2 and pantothenic acid. In every 50 grams of walnuts, water accounts for 3.6%, and it also contains 7.2 grams of protein, 31 grams of fat and 9.2 grams of carbohydrates. [0003] Walnut kernels contain 22.18% crude protein, of which soluble protein is mainly composed of glutamic acid, followed by arginine and walnut kernel aspartic acid. Crude lipids are 64.23%, of which neutral lipids account for 93.05%; triacylglycerols in neutral lipids are 82.05%, sterol lipi...
