Problems solved by technology

Although the above two patents have considered the ratio of the three fatty acids and the content ratio of the n-6 series fatty acids to the n-3 series fatty acids, the defects are: they are not combined with the actual dietary situation, and the intake of non-cooking oil fatty acids in the actual diet of residents is not considered. , and did not consider the changes in unsaturated fatty acids caused by factors such as heating during cooking
[0017] Judging from the existing blending oil patents, the destruction of unsaturated fatty acids by factors such as heating during cooking is ignored, and the intake of polyunsaturated fats that are not resistant to high temperatures and saturated fats and monounsaturated fats that are resistant to high temperatures are not considered. Fat is used together through high-temperature intake, and it also lacks a reasonable ratio of fatty acid composition when used together

Abstract

The invention discloses low-temperature used nutritional edible blend oil containing debitterized linseed oil and balanced omega-6 and omega-3 unsaturated fatty acids. The blend oil contains 20-65 parts of debitterized linseed oil, 0-10 parts of DHA or EPA rich oil and 30-80 parts of linoleic acid rich oil. The blend oil has no bitter taste and good flavor when used at low temperature, wherein omega-6 and omega-3 unsaturated fats respectively account for 30-60% and 20-40% of the weight of the total fat, DHA and EPA in the unsaturated fats accounts for 0-3% of the total fat content, and the ratio of the omega-6 and omega-3unsaturated fatty acids is (1-2) to 1. The debitterized linseed oil is prepared by winterization, tangential flow crude membrane separation, chromatographic separation andtangential flow fine membrane separation. The blend oil is blended on the basis of considering the influence of fatty acids in non-cooking oil in foods on polyunsaturated fats during heating and theamount of each fatty acid actually entering a human digestive system, and when the blend oil is matched with high temperature resistant cooking oil with high monounsaturated fatty acid content and lowomega-6 unsaturated fatty acid content in use, the ratio of the omega-6 and omega-3unsaturated fatty acids is reasonable so that the purpose of reasonable and healthy supplementation of the omega-6 and omega-3 unsaturated fatty acids can be achieved.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a low-temperature nutritious edible blending oil containing debittered linseed oil and balanced omega-6 and omega-3 unsaturated fatty acids. Background technique [0002] Linen ( Linum usitatissimum L.) is an annual herb of the Linaceae family. Flaxseed is the seed of flax. Zhang Qian of the Western Han Dynasty brought it back to my country via the Silk Road, so flax is flax. At present, flax in the world is divided into three varieties: flax for oil, flax for oil and fiber, and flax for fiber. Edible linseed oil is an oil made from linseed oil. It has attracted more and more attention because it is rich in the fatty acid α-linolenic acid (ALA; α-inolenic acid) necessary for the human body. Among them, α-linseed The acid content can be as high as 50-60%. Studies have shown that α-linolenic acid can esterify cholesterol and metabolize it out of the human body, which ...
