Problems solved by technology

However, in this preparation method, due to long-time high-temperature heating, the α-linolenic acid, protein and other substances beneficial to the human body that are rich in flaxseed will be decomposed and denatured, and the nutritional value of flaxseed will be greatly reduced; at the same time, the obtained by grinding method Flaxseed powder has large particles and low solubility
[0006] At present, the methods for extracting flaxseed lignans and dietary fiber include organic solvent extraction, ultrasonic method or microwave treatment, but these methods will have chemical reagent residues, which is not conducive to comprehensive utilization

Abstract

The invention belongs to the technical field of functional foods, and especially relates to a preparation method of skimmed linseed powder. The preparation method of the skimmed linseed powder comprises the following steps: 1) detoxifying linseeds; 2) skimming detoxified linseeds; and 3) preparing linseed powder, namely mixing the skimmed linseed meal with water, carrying out vacuum concentration,carrying out homogenization, and carrying out spray-drying so as to obtain the skimmed linseed powder. During the preparation process of the linseed powder, a microwave method, a spray-drying methodand a supercritical CO(2) extraction method are adopted so that ingredients, including lignan, dietary fiber and the like, enriched in the linseeds can be preserved to the maximum extent during the detoxifying and oil-pressing processes; and thus, application potentials of the skimmed linseed powder in the aspects of preventing cancer, resisting cancer and reducing weight are increased.

Description

Technical field [0001] The invention belongs to the technical field of functional foods, and in particular relates to a preparation method and application of defatted flaxseed powder. Background technique [0002] Flaxseed protein is a protein with a high content of branched-chain amino acids. As a food, it can perform specific physiological functions in special populations, such as malnourished patients suffering from cancer, burns, trauma, and hepatitis. Flaxseed is also an excellent source of lysine, glutamic acid and histidine. These three amino acids are of great significance for the body to maintain normal immune function. In addition, flaxseed is also rich in nutrients such as lignans, soluble dietary fiber, minerals and vitamins. [0003] Lignan, as a kind of phytoestrogens, has attracted great interest, mainly because it has been proven to have anti-tumor effects and strong antioxidant activity. It can effectively inhibit harmful chemicals that promote cancer and is a str...
