Abstract

The invention discloses walnut milk. The walnut milk comprises 89.47 to 93.23 weight percent of fresh milk, 1 to 2 weight percent of lactalbumin, 2 to 3 weight percent of cold-pressed walnut oil, 3.5 to 5 weight percent of sweeting agent, 0.1 to 0.2 weight percent of calcium carbonate, 0.02 to 0.03 weight percent of ferrous sulfate, 0.05 to 0.1 weight percent of zinc sulfate and 0.1 to 0.2 weight percent of emulsion stabilizer; and the preparation method comprises the following steps of: heating refrigerated fresh milk subjected to pasteurization to 48 to 52 DEG C according to the weight percentage; adding the lactalbumin which is preheated to 48 to 52 DEG C with stirring; reheating the lactalbumin to 75 to 80 DEG C; adding the cold-pressed walnut oil, the sweeting agent, the calcium carbonate, the ferrous sulfate, the zinc sulfate and the emulsion stabilizer; and homogenizing, sterilizing and cooling to prepare the walnut milk. The milk product of the invention has balanced nutrition, contains sufficient polyunsaturated fatty acid, has an important promotion effect on brain development of fetus, and is convenient to drink and can be easily absorbed and utilized by human bodies; and the preparation method is simple and practical and is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the field of nutrition-enhanced beverages for special groups of people, in particular to nutritionally blended walnut milk suitable for drinking by pregnant women in the middle and late stages of pregnancy; the invention also relates to a preparation method of the walnut milk. Background technique [0002] At present, studies on pregnant women in the middle and late stages of pregnancy have shown that they have the following physiological characteristics: [0003] 1. Endocrine changes: the secretion of human chorionic gonadotropin, human chorionic growth hormone, estrogen, progesterone and other hormones increases. Under the action of the above hormones, the anabolism and catabolism of pregnant women are greatly enhanced at the same time; [0004] 2. Changes in blood volume and hemodynamics: blood volume increases, about 35% to 40% higher than before pregnancy, among which, the plasma volume increases by 45% to 50%, and the num...
