Abstract

The invention provides barley grass powder rich in resveratrol and a preparation method for the barley grass powder. The barley grass powder comprises the following raw materials in part by weight: 1 to 3 parts of barley grass powder and 1 part of grape seed powder, wherein 100 grams of barley grass powder contains 6.25 milligrams of resveratrol. The preparation method for the barley grass powdercomprises the following steps of: pretreating the raw materials, crushing and juicing, concentrating, spray-drying, performing physicochemical measuring, obtaining the barley grass powder serving as a finished product, adding the grape seed powder and stirring, measuring the content of the resveratrol and the like. According to the method, the grape seed coarse powder is added into the spray-dried barley grass powder in a ratio, so that the barley grass powder is rich in resveratrol effective ingredients, and the functionality of resisting oxidation, aging and diseases relevant to aging by the barley grass powder is replenished. The barley grass powder is pure natural, does not have any additive and is suitable to be eaten by all people.

Description

technical field

[0001] The invention relates to a vegetable powder making process, in particular to a spray-drying method for preparing barley powder rich in resveratrol and a preparation method thereof. Background technique

[0002] Barley seedlings are functional food resources available for development. In the early 1990s, there was a frenzy of eating barley green juice for health care in Japan. In my country, the research on barley seedlings has been relatively mature in recent years, and the nutritional and health effects of the original leaves on the human body have been affirmed by relevant researchers, but how to make it convenient to eat and retain its original functional components is the key to the commercial development of barley seedlings . According to the report of Feng Qihao, a Chinese scholar, fresh wheat seedlings can be made into wort powder by freeze-drying method, which can keep most of the biologically active substances, but the cost is too high in larg...

Embodiment Construction

[0022] The barley grass powder of this embodiment, its raw material composition by weight is: 1-3 parts of barley grass, 1 part of grape seed powder. Its preparation method is made according to the following steps:

[0023] 1) Pretreatment of raw materials of barley seedlings: in the early stage of earing, the seedlings are 27cm±3cm high and harvested at a distance of 3-5cm from the roots. Blanching; the blanching temperature is 96-100°C, and the time is 1-2 minutes. After blanching, rinse with cold water to quickly cool down;

[0024] 2) crushing and squeezing the juice: the raw materials after step 1) pretreatment are crushed, filtered, and residues are removed to obtain barley seedling juice;

[0025] 3) Concentration: the barley juice obtained in step 2) is concentrated by vacuum and continuous film; the solid-to-liquid ratio of the barley juice is 15% to 30% as the termination point;

[0026] 4) Drying: Spray-dry the concentrated feed liquid in step 3), the air inlet te...
