Problems solved by technology

[0003] The usual walnut oil is steamed and hot-pressed at high temperature. It is easier to extract the oil by high-temperature pressing, but the crude oil produced has more impurities and needs to be treated by high-temperature and chemical methods. If the high-temperature time is too long, the product will form trans-acid oil. It is not conducive to human health; steam distilled oil is easy to hydrolyze, resulting in the formation of polymers of polyunsatur

Embodiment Construction

[0007] (1), select the dried wild walnuts of the year, remove mildew and rotten walnuts, put them into a cleaning tank, add clear water to stir and clean them for 3-10 minutes, and drain the sewage; soak them in 4% sodium hydroxide solution for 8-15 minutes Skin sterilization treatment;

[0008] (2), after being dehydrated with a centrifuge, put it into a flat dryer and dry it until the water content is 6%, and cool naturally;

[0009] (3), break shell with disc crusher, carry out shell kernel separation with cylindrical separating sieve, obtain the walnut kernel that contains shell content and be lower than 5%;

[0010] (4) Dry the nuts with a flat dryer until the water content is ≤3%, and the drying temperature is controlled to be ≤45°C;

[0011] (5), the nuts enter the hydraulic cold press and squeeze, and the centrifuge is equipped with a 180-250 mesh sieve for centrifugal deslagging to obtain crude oil;

[0012] (6), the crude oil enters the settling tank, seals and fil...

Abstract

The preparation process of cold squeezed wild walnut oil includes the following steps: sorting, washing, sterilizing; dewatering and cooling; separating kernel from shell; drying kernel at temperature lower than 45 deg.c; cold squeezing in a cold press and eliminating slag; depositing; cooling the oil below 0 deg.c to eliminate impurity; separating protein through heating to 40 deg.c, adding pure water of 3-5 wt% of oil while stirring, standing while maintaining the temperature to deposit for at least 3 hr and taking the supernatant walnut oil; decolorizing, deacidifying and deodorizing; and filtering. The cold squeezed wild walnut oil is clear and pure, and has the nutritious components in walnut maintained.

Description

technical field [0001] The invention relates to an edible oil and a processing method thereof, in particular to a preparation process of cold-pressed wild walnut oil. Background technique [0002] Walnut oil is rich in unsaturated fatty acids, the content of which is close to 80%. Among them, the content of linoleic acid and linolenic acid is the highest among other edible oils, and it is rich in various vitamins, calcium, magnesium and other trace elements, which can soften blood vessels, reduce Cholesterol content in the human body, preventing arteriosclerosis and thrombosis has a positive effect, and can also prevent and treat many common modern affluent diseases such as hypertension, hyperlipidemia, diabetes, obesity, etc. In developed countries, eating walnut oil has become a consumption trend. Designate it as space food. [0003] The usual walnut oil is steamed and hot-pressed at high temperature. It is easier to extract the oil by high-temperature pressing, but the c...
