Embodiment 1

[0031] Cut off the 1.3-1.5m high bamboo grass plant, wash the dust and soil with a high-pressure water gun, send 1 ton of fresh grass to the chopping and kneading machine, and transport the kneaded material to the hydraulic juicer to squeeze the juice. The obtained juice is 600-700kg, and the residue is 300-400kg. The grass residue is directly used to make silage feed with a baler and a coating machine. Filtration through a pressure membrane with a fiber tube with a diameter of 0.540-640kg is used to make the sports drink of Huangzhucao grass juice. ), 45°C (10 minutes), and 75°C (5-8 minutes) are the three best coagulation points, and then enter the stacked high-speed centrifuge (4000-7000r / m), centrifugal separation, the liquid part returns to 6000 Dal Filtrate again in the film, and the paste part enters the spray drying tower for drying (inlet air temperature 190-220°C, outlet air temperature 75-85°C, the dried product is light green to light yellow powder product, weight ...

Embodiment 2

[0033] Cut off the alfalfa plants in full flowering stage, wash the dust and soil with a high-pressure water gun, send 1 ton of fresh grass to the chopping and kneading machine, and send the kneaded material to the beater, and add water according to the grass-to-water ratio of 1:1 for beating , and then send the slurry into a plate and frame filter press to press and squeeze the juice to obtain 1600-1650kg of juice and 350-400kg of grass residue. The grass residue is directly used to make silage feed with a baler and a coating machine. Filtration and concentration in a 0.1-0.01u fiber tube pressure membrane, and the permeate is filtered through a 6000-dalton pore diameter fiber tube pressure membrane. The permeate is about 1540-1640kg and used to make Huangzhu grass juice sports drinks. The concentrate is twice Combine about 60kg together, transport to the temperature treatment tank for temperature treatment, 55°C (10 minutes), 80°C (5-8 minutes) are the two best coagulation po...

Abstract

The present invention discloses a method for extracting protein from plant leaf, it belongs to feed production and food processing areas. The invention includes such steps as chopping, kneading, pulping and squeezing. The concentrated liquid and the penetration liquid can be obtained by pressing juice through a filter. The plant leaf protein prepared through the concentrated liquid heating or cooling, centrifugal separating, drying. Residue can be made into meal or feed and so on. The penetration liquid can be made into beverage. The leaf protein can be obtained wherein the content of protein is 30-60%, and is rich in vitamin C, vitamin E, fat and carotenoids.

Description

technical field [0001] The invention belongs to the fields of biological feed production and food processing, and in particular relates to a method for compound extraction of plant leaf protein and the application of the method in the extraction of protein from leaves of imperial bamboo grass and the production of grass juice beverage of imperial bamboo grass. Background technique [0002] Leaf protein is a protein concentrate (leaf protein concentrate. LPC for short) prepared by pressing fresh green plant stems and leaves as raw materials, extracting juice, separating protein in the juice, concentrating and drying. A large number of studies have shown that the protein content of leaf protein products is 55% to 72%, the available carbohydrates are 5% to 20%, the crude fiber is 0.5% to 1.5%, the fat is 7% to 25%, the ash content is 0.5% to 1.5%, and the total energy is average It is 439kcal / 100g. Leaf protein contains 18 kinds of amino acids, including 8 kinds of amino acids...
