Problems solved by technology

However, due to the high oil content in walnuts, directly fermenting walnuts as raw materials has the problems of unstable and easy-to-stratify fermented milk, and walnuts, as a raw material of plant origin, are difficult to ferment to prepare a flavor, mouthfeel, Purely fermented yoghurt with ideal color etc., most of the prior art uses it as fermented milk drink, but fermented milk drink is far inferior to pure fermented yoghurt in terms of nutrition and health due to the addition of various additives such as sugar and stabilizers. type yogurt

Abstract

The invention relates to the technical field of food processing, in particular to walnut fermented milk and a preparation method thereof. The method of the present invention comprises the following steps: 1) baking the uncoated walnut kernels at 145-165° C. for 5-25 minutes; 2) deoiling the baked walnut kernels until the oil content is 20-50% , to obtain semi-skimmed walnut kernels; 3) mixing the semi-skimmed walnut kernels with a stabilizer, carbon source and water to obtain walnut slurry; 4) fully mixing the walnut slurry to sterilize, inoculate, and ferment . In the present invention, the aroma of walnuts can be effectively improved after being baked at high temperature. On this basis, the ideal flavor of the system can be guaranteed after removing part of the oil, and the quality is stable and nutritious can be obtained by removing the oil to the above level. Rich fermented milk.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a walnut fermented milk and a preparation method thereof. Background technique [0002] Walnut, also known as walnut, is one of the four major nuts with high nutritional value and economic value. The main components of walnut kernels are fat and protein, the fat content is as high as 60-70%, of which unsaturated fatty acids such as oleic acid, linoleic acid and linolenic acid account for more than 90% of the total fatty acid, and the protein content reaches 15%-20%, And walnut protein contains 18 amino acids, of which 8 amino acids are essential for the human body. In addition, walnuts also contain potassium, calcium, iron, manganese, zinc, copper, selenium and other trace elements and folic acid, niacin, pantothenic acid, etc. vitamins. Therefore, walnuts have antioxidant, anti-fatigue, prevention of cardiovascular and cerebrovascular diseases, and reduce the risk of d...
