Abstract

The invention discloses barley tender seedling powder rich in phenolic acid and a production process thereof. The production process is characterized by comprising the following steps of performing germinating of barley grains under a non-stress condition, performing treating on enriched phenolic acid by using plasma activated water culture combined with gamma-aminobutyric acid, performing rinsing, then performing freeze-drying, crushing and sieving, performing compounding with sucrose, citric acid, apple powder, banana powder and orange powder, and carrying out sterilizing and packaging to obtain the barley seedling powder rich in phenolic acid. The raw material barley is naked barley, the product is bright green or yellow green in color, fragrant and mellow in taste and high in reconstituability, and the phenolic acid content of the product is 200-350 mg / 100 g. The product has the effects of resisting oxidation, purging gut, losing weight, maintaining beauty, enhancing immunity, delaying senescence and the like.

Description

[0001] 1. Technical field [0002] The invention relates to a barley tender seedling powder rich in phenolic acid and a production process thereof, belonging to the technical field of food deep processing. [0003] 2. Technical Background [0004] Phenolic acids are a class of natural active substances that widely exist in plant-derived foods. According to their carbon structure, they are generally divided into hydroxycinnamic acid and hydroxybenzoic acid. The former mainly includes p-coumaric acid, ferulic acid, sinapic acid and caffeic acid. , the latter mainly includes phenolic acids such as p-hydroxybenzoic acid, gallic acid, vanillic acid, syringic acid and protocatechuic acid, which are mostly covalently combined with sugars and organic acids to form phenolic acid derivatives. Most of the phenolic acids have pharmacological activity: ferulic acid can increase coronary blood flow, protect ischemic myocardium, inhibit the contraction of aortic smooth muscle, and resist the ...
