Abstract
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...
