Wheat Green and Its Processing Technology

Barley and barley leaves are rich in barley green, enzymes, natural vitamins, minerals and amino acids. Wheat green is not a medicine, but it can eliminate toxins accumulated in the blood for a long time. It has a good auxiliary effect on asthma, constipation, diabetes and other diseases. In addition, wheat green can also prevent coronary heart disease, cerebral hemorrhage, liver disease, poor vision and other diseases. A series of wheat leaf products have been developed abroad, such as wheat leaf fiber food, wheat leaf health food, wheat straw juice beverage, wheat green cola and so on. The market is selling well. At present, the main production bases of wheat green are in the United States, Canada, Australia and so on. Because of its pure nature and its effect on health and longevity, it caters to people's pursuit of "returning to nature", so it is popular in North America, Europe, Southeast Asia and Australia. The annual turnover has reached 23-2.7 billion US dollars. The domestic market has not been listed for a long time. Zhejiang Jinbakai Plant products Co., Ltd. cooperated with the United States to develop wheat green products; Huitang "Green finger" brand wheat green products in Heilongjiang Huatang, as a high-tech product with national patent, has been tested and evaluated by relevant departments for many times and listed as a national torch plan project.

The results of our research and analysis also show that wheat green is rich in nutrition. The development of wheat green is to make use of rich wheat crop resources growing in a pollution-free environment to produce wheat green nutrition and health food. It is a product made from the tender leaves of barley and wheat seedlings as the main raw materials, supplemented by malt, dextrin, gelatin and so on.

1. Technological process Ⅰ

Cultivate wheat seedlings in the incubator, watering every day, never spraying pesticides, no moldy roots, no miscellaneous bacteria → cut up when it grows to 16 cm, at this time, the highest nutritional content of wheat seedlings → washed, put into the blender, beat into wheat seedling juice → into-60 ℃ rapid freezer to freeze the wheat seedling juice into the most rapid freezing method, never lose nutrients → rapid drying, wheat seedlings have become a green solid containing less than 1% moisture Still maintain all nutrients → dry solid crushing that is powdered wheat seedling powder → made of wheat seedling powder, sampling in the quality inspection room, do bacterial culture → qualified wheat seedling powder can be aseptic aluminum foil automatic packaging factory, @ @ 222wheat powder @ all over the country.

2. Processing process Ⅱ

Raw materials are selected to remove impurity, →, disinfection, → cleaning, cutting, → drying, → juice extraction, → wheat leaf residue drying, → crushing, → ingredient → drying to produce green powder products. The product can be directly mixed with granule or capsule.

3. The preparation method of wheat chlorin powder Ⅲ

The leaves of cut barley seedlings (or wheat seedlings) are prepared by screening, cleaning, dehydration, crushing, filtration, homogenization and spray drying. it is characterized by the selection of raw materials: for barley seedlings growing to a certain height, a certain amount of effective tender leaves are cut as raw materials for the preparation of barley green powder. Pretreatment of raw materials: after removing impurities and yellow leaves, rinse with clean water of 8: 15 ℃, and then dry the washed barley seedlings with hot air at a temperature of 50: 60 ℃. Grinding and filtration: the effective amount of clean and dry barley seedlings is ground into paste by colloid grinding, the paste is filtered, the crude fiber of barley seedling is filtered, and then diluted with water to remove the paste of crude fiber, after the effective time of precipitation, filter the fine fiber and other filamentous impurities in the diluent, the filter screen is 80mm 200 mesh. Ingredient and concentration: add 4%-6% lactose or dextrin as disintegrating agent to the filtered barley leaf juice, stir evenly and send it into a vacuum concentrator to concentrate. The temperature in the concentration process is 46-55 ℃, the vacuum is 620-660 mm Hg, and the concentration time is 1-1.5 hours. The concentrated product is an emulsion with 50% concentration. High temperature sterilization and homogenization: the high temperature sterilization temperature of barley green powder emulsion with 50% concentration is 115 ~ 135 ℃, and the sterilization time is 0.3 ~ 0.6 seconds. After sterilization, the wheat green emulsion is homogenized. The homogenized wheat green emulsion was spray dried. The inlet air temperature in the spray drying process was 130 ~ 160 ℃, and the drying time was 0.2 ~ 0.4 seconds. The powder was made into wheat green powder after spray drying, and the finished product was packaged.

The key to the preparation technology of wheat green and its solution is to add the wort filter residue produced in the production process as a functional component of the product, which not only makes full use of the raw materials of wheat seedlings and reduces the production of by-products. At the same time, the content of dietary fiber in the product is increased, and the health care effect of the product is improved.

In order to prolong the shelf life of the product, the solution is to add cyclodextrin to the mixed wort in the preparation process, which can effectively prevent the browning of the product.
