Problems solved by technology

[0005] The existing walnut oil refining process includes degumming, deacidification, decolorization, washing, deodorization and other processes, which have the following disadvantages: 1. The process is cumbersome, the refining efficiency is low, and some functional components are lost after refining; 2. During the refining process, a large amount of acid will be consumed , alkali, water, not only cause resource consumption and environmental pollution, but also cause acid, alkali and heavy metal residues, eating is not good for human health; 3, deodorization requires high temperature above 200 ℃, the functional components in the oil are destroyed, resulting in nutrient loss

Embodiment 1

[0030] A method for preparing walnut oil for pregnant women, comprising the following steps:

[0031] S1, material selection: select wild walnuts with no impurities, no mildew, no peculiar smell and clean shell surface as raw walnuts, and check the moisture content, acid value and peroxide value of raw walnuts. The standard is: moisture content ≤ 8.0% , acid value (mgKOH / g) ≤ 0.5, peroxide value (mmol / kg) ≤ 0.5;

[0032] S2, taking kernels: Use a special sheller to crack the walnut shells, and select walnut kernels without mildew, full particles, and normal color, and set them aside;

[0033] S3, peeling: use 2 to 3 times the weight of NaCO 3 After soaking the walnut kernels in the solution for 8-10 minutes, wash them with 3-4 times the weight of water for 2-3 times to obtain the peeled walnut kernels; among them, NaCO 3 The mass fraction of the solution is 1% to 3%, and the temperature is 50 to 60°C;

[0034] S4, drying: drying the peeled walnut kernels in an oven until th...

Abstract

The invention relates to a preparation method of walnut oil for pregnant women and infants. The preparation method comprises the following steps of: selecting materials, taking kernels, peeling, drying, cold-pressing, hydrating, dewatering, storing or canning and the like. The method has the beneficial effects that the production process is simple, the investment cost is low, the energy consumption is low, the environment is protected, the produced walnut cake can be repeatedly utilized, the prepared walnut oil is low in oxidation degree of oil and low in loss of functional components in the oil, artificial additives are avoided, residues of acid, alkali and heavy metals are effectively avoided, and the walnut oil conforms to the national standard and is suitable for pregnant women and infants to eat.

Description

technical field [0001] The invention relates to the field of walnut oil preparation, in particular to a preparation method of walnut oil for pregnant women. Background technique [0002] Data show that the fat intake and fatty acid composition of pregnant women, infants and young children are crucial to the growth and development of infants and young children. Among them, linoleic acid and α-linolenic acid play an important role in the healthy development of infants. Linoleic acid is an omega-6 polyunsaturated fatty acid, which cannot be synthesized by the human body but must be ingested from food. It can promote skin development, maintain body nutrition and health, and help moisturize hair. α-linolenic acid, which belongs to omega-3 polyunsaturated fatty acids, is the core substance that constitutes human cells and an important component of the fetal brain. Insufficient intake will affect the memory and thinking ability of infants and young children. [0003] In the proce...
