Method of preparing instant nursing barley green product through using hot-air dehydrated barley grass powder as raw material

Abstract

The invention discloses a method of preparing an instant nursing barley green product through using hot-air dehydrated barley grass powder as a raw material, and belongs to the technical field of research and development of health care foods. The method comprises the following steps: taking the hot-air dehydrated barley grass powder as the main raw material, adding other nutrient substances and food fillers (such as maltodextrin and beta-cyclodextrin) as processing auxiliary materials to produce the instant nursing barley green health care product, and specifically comprises the steps of extraction, concentration, mixing, pH value regulation, drying, packaging and the like. Compared with the conventional extraction method, the nutrients are extracted by a double-frequency ultrasonic wall breaking method from the hot-air dehydrated barley grass powder; the method is short in extraction time, high in nutrient extraction ratio and low in loss; the auxiliary materials can be added according to demands of different users, so that the quality of the barley green product can be improved, the product can achieve a better pertinence, and consumers can purchase the product with more accurate purposes; a low-temperature microwave vacuum spray drying method is adopted, so that the method is short in drying time, and low in damage to thermosensitive substances; the product is fine and smooth, and good in solubility.

Description

technical field [0001] The present invention relates to a kind of method that uses hot-air dehydration barley grass powder as raw material to prepare instant conditioning barley green product, specifically relates to a kind of hot air-dried barley grass powder as main raw material, and then adds other nutrients, food filler (such as malt paste The invention relates to a method of instant conditioning barley green health food produced by processing supplementary materials, and belongs to the research and development technical field of health food. Background technique [0002] Barley Grass Powder is processed from young barley leaves, rich in plant brass, active enzymes, chlorophyll, protein, amino acids, vitamins and minerals. Barley chlorophyll is a compound nutrient made from the young leaves of barley, wheat or highland barley as raw materials, extracting active ingredients and then drying. It is rich in nutrients, mainly including plant flavonoids, active enzymes, chloro...

Problems solved by technology

The three-step alcohol extraction takes too long, and the pH of the enzymatic hydrolysis method is acidic. During the extraction process, acidic conditions promote the decomposition and browning of chlorophyll, resulting in the loss of chlorophyll.

Vacuum freeze-drying has a high nutrient retention rate but high cost and is not suitable for large-scale industrial production. Spray drying is continuous drying, the drying time is short but the nutrient loss is large, and high-quality barley greens cannot be produced.
