Embodiment 1

[0016] The high-oleic-low-acid-value wheat germ blended oil of Example 1 includes the following raw materials in mass proportions: 40% wheat germ: 20% camellia seed: 20% olive: and 20% Moringa seed.

[0017] The preparation method of the high oleic acid low acid value wheat germ blended oil of embodiment 1 is:

[0018] First, weigh the raw materials according to the mass ratio, pulverize them, mix them evenly and add them to the multi-stage separation supercritical CO 2 In the extraction kettle of the extraction equipment, tighten the lid of the extraction kettle and open the CO 2 The gas cylinder, the gas source enters the gas valve, and the extraction process conditions are adjusted. The extraction temperature is 55°C, the extraction pressure is 40MPa, and the extraction is started. The extraction time is 1.0h. After the extraction is completed, the CO in the supercritical state 2 and the mixture of blended oil will enter the separation tank for decompression separation, an...

Embodiment 2

[0022] The high-oleic-low-acid-value wheat germ blended oil of Example 2 includes the following raw materials in mass proportions: 55% of wheat germ: 20% of camellia seed: 15% of olive: and 10% of Moringa seed.

[0023] The preparation method of the high oleic acid low acid value wheat germ blended oil of embodiment 2 is:

Abstract

The invention discloses high-oleic-acid low-acid-value wheat germ blend oil, which comprises the following raw materials in percentage by mass: 40-55% of wheat germ, 20-30% of camellia seeds, 15-25% of olive, and 10-20% of moringa seeds. The high-oleic-acid low-acid-value wheat germ blend oil is subjected to multi-stage separated supercritical CO2 extraction and molecular distillation refining. The multi-stage separated supercritical CO2 extraction not only can keep higher extraction rate, but also can separate moisture, free fatty acid, odor ingredients, pigment ingredients and the like. Refining treatment is conducted by using a molecular distillation technology, to obtain the high-oleic-acid low-acid-value wheat germ blend oil with the oil yield of being more than 7%, acid value of being lower than 0.5 (KOH) / (mg / g), unsaturated fatty acid content of being more than 94%, and the oil acid content of being 55%-65%. The high-oleic-acid low-acid-value wheat germ blend oil not only can make up the defect that the oil acid content of wheat germ is low, but also realizes the rapid refining of grease, and greatly reduces the acid value of the obtained blend oil.

Description

technical field [0001] The invention relates to an edible blending oil, in particular to a high-oleic-low-acid-value wheat germ blending oil and a preparation method thereof. Background technique [0002] Monounsaturated fatty acids have only one active bond, and the first active bond is behind the ninth carbon, referred to as omega-9 series fatty acids, and oleic acid is monounsaturated fatty acid. Studies have shown that oleic acid can reduce the content of cholesterol in the blood, reduce its deposition on blood vessels, and prevent arteriosclerosis. The biggest difference between oleic acid and polyunsaturated fatty acids is that oleic acid does not lower good cholesterol, but only lowers total cholesterol and bad cholesterol. While polyunsaturated fatty acids lower total and bad cholesterol, they also lower good cholesterol. Therefore, high oleic acid is very important for the cardiovascular and cerebrovascular health of middle-aged and elderly people. However, the o...
