preparation example Construction

[0028] The present invention also relates to the preparation method of above walnut dew, and described preparation method comprises the following steps:

[0029] a. The walnut kernels are treated with lye, peeled, and refined to obtain walnut kernel pulp, wherein the weight percentage of walnut kernels and lye is 1: (2-25), preferably 1:5, and set aside;

[0030] b. Prepare a mixed solution of compound emulsifying thickener, white granulated sugar, sodium carbonate and deionized water according to the weight percentage, dissolve the compound emulsifying thickener, white granulated sugar and sodium carbonate in deionized water, and ensure the compounding The ratio of the weight of emulsifying thickener, white sugar, and sodium carbonate to the weight of deionized water is controlled at 1: (1-6), preferably 1:2, and set aside;

[0031] c. Prepare the walnut pulp in step a and the mixed solution in step b, homogenize, fill and sterilize to obtain the walnut dew.

[0032] In the ...

Abstract

The invention discloses walnut juice and a preparation method thereof. The walnut juice is composed of the following components in percentage by weight: 3.5-6% of walnut kernels, 6.5-7.5% of white granulated sugar, 0.1-0.2% of a compound emulsion thickener, 0.03-0.05% of sodium carbonate and the balance being deionized water. By reasonably setting a formula and selecting and proportioning additives, the adding amount of food additives can be decreased by more than 50% and only accounts for 0.1% of the total amount, moreover, a walnut juice product has the good stability, and can be capable of being stored for a long time.

Description

technical field [0001] The invention belongs to the technical field of beverage processing in the food industry, and in particular relates to a walnut dew and a preparation method thereof. Background technique [0002] Walnuts are extremely nutritious and have the effects of strengthening the body, nourishing the brain, beautifying the face, and prolonging life. Modern scientific research shows that every 100 grams of walnut kernels contain 50-64 grams of fat, of which 71% are linoleic acid, 12% are linolenic acid, and 15-20 grams of protein. The fat and protein contained in walnuts are the best nutrients for the brain, and because the main component of the fat contained in walnuts is linoleic acid glycerides, not only will it not increase cholesterol after eating, but it can also reduce the intestinal absorption of cholesterol Therefore, walnuts can be used as a tonic for patients with hypertension and arteriosclerosis. In addition, the trace elements zinc and manganese c...
