Problems solved by technology

In order to shorten the growth time of barley or wheat and increase the yield, people usually use chemically synthesized fertilizers; the use of chemical fertilizers weakens the production capacity and resistance to diseases and insect pests of crops. On the one hand, a large amount of beneficial trace elements in the soil cannot be effectively absorbed by crops. On the other hand, crops are prone to pests and diseases, which increases the possibility of using pesticides, and indirectly leads to the harm of pesticide residues and environmental pollution
In the production process of barley young leaf products, conventional drying methods are used, and the high temperature in the drying process can easily destroy vitamins and other nutrients in the product
In addition, most of the barley leaf products on the market do not separate the nutrients with different functions, so that they cannot provide targeted nutritional supplements for different groups of people

preparation example Construction

[0019] The preparation process route of the present invention mainly comprises:

[0020] 20-30cm highland barley seedlings → pretreatment → sterilized and soaked at 80°C → pressed dry → supercritical extraction → to obtain the extracted components →

[0021]

[0022] Preparation method of the present invention, concrete process is as follows:

[0023] (1) Harvest the young highland barley seedlings that grow to 20-30 cm from the Qinghai-Tibet Plateau, and transport them to the production workshop within 30 minutes after harvesting. After removing impurities, wash with water. The washed young highland barley leaves are soaked in 80° C. pure water for 3 minutes to kill enzymes and sterilize. After taking it out, rinse it with pure water, cool it down to room temperature quickly, and then dry it with a pressure dryer.

[0024] (2) The dried highland barley leaves are put into SFE equipment for supercritical extraction, and the extracted components containing green juice of ...

Embodiment 1

[0030] Harvest 20-30 cm highland barley tender seedlings in 1000 square meters of farmland, and get 243kg highland barley tender leaves, which will be transported to the production workshop within 30 minutes after harvesting. Remove impurities such as dead leaves and weeds, wash them repeatedly with tap water, and then rinse with pure water.

[0031]The washed young highland barley leaves are soaked in 80° C. pure water for 3 minutes to kill enzymes and sterilize. Rinse it with pure water after taking it out, cool it down to room temperature quickly, and then dry it with a pressure dryer to obtain 123.3 kg of dried material. The dried barley leaves enter the SFE equipment for supercritical extraction, and 37.4 kg of extract components containing barley grass leaf juice and 81.2 kg of extract components containing dietary fiber are collected.

[0032] Turn on the cooling brine of the colloidal grinder, add 16.8kg of pure water to the extracted components of 37.4kg of highland ...

Embodiment 2

[0037] About 20 days after fertilization and irrigation on the farmland that has been harvested once, the regenerated young barley leaves have reached the requirement of 20-30 cm. Harvesting the regenerated young highland barley seedlings of 1000 square meters of farmland yielded 128 kg of young highland barley leaves. Shipped to the production workshop within minutes. Remove impurities such as dead leaves and weeds, rinse with tap water repeatedly, and then rinse with pure water.

[0038] The washed young highland barley leaves are soaked in 80° C. pure water for 3 minutes to kill enzymes and sterilize. After taking it out, rinse it with pure water, cool it down to room temperature rapidly, and then dry it with a pressure dryer to obtain 64.3 kg of pressed dry material. The dried barley leaves were put into SFE equipment for supercritical extraction, and 19.6 kg of extract components containing green barley juice and 41.2 kg of extract components containing dietary fiber wer...

Abstract

The invention provides a preparation method for simultaneously extracting Tibet barley serum and Tibet barley dietary fiber. The method sequentially comprises the following steps of: cleaning tender Tibet barley leaves, soaking the cleaned leaves into hot water for enzyme inactivation and sterilization, cleaning the leaves again, and dry-pressing the leaves; then performing supercritical extraction, and collecting an extraction component containing the Tibet barley serum and an extraction component containing the Tibet barley dietary fiber respectively; performing low-temperature grinding and spray drying on the extraction component containing the Tibet barley serum to obtain powdery Tibet barley serum; and performing high-speed centrifugal dehydration, constant-temperature drying and super-micro crushing on the extraction component containing the Tibet barley dietary fiber to obtain powdery Tibet barley dietary fiber. The method ensures the reality of products, reduces the cost of raw materials, and has no pollution.

Description

technical field [0001] The invention relates to the technical field of bioengineering, in particular to a preparation method for simultaneously extracting highland barley grass juice and highland barley dietary fiber. Background technique [0002] In recent years, domestic and foreign medical experts and nutrition experts have highly appraised the efficacy of barley leaf food in medicine and health preservation. Barley young leaves are barley seedlings that have grown to 20-30 cm, and the seedlings at this stage contain the most abundant nutrients. Barley Grass Green Juice products have been popular in Japan, Taiwan, Europe, America and other countries for more than ten years. [0003] Highland barley is a cereal crop of the genus Barley in the Poaceae family. Because the inner and outer glumes are separated and the kernels are exposed, it is also called naked barley, barley, and rice barley. Highland barley has a long history of cultivation on the Qinghai-Tibet Plateau, a...
