Embodiment 1

[0024] (1) Processing raw materials: use fresh alfalfa, take its top 30cm and plant leaves as processing raw materials, alfalfa should be processed as soon as possible after harvesting, if it needs to be stored for a short time, it should be sealed in a fresh-keeping bag and placed at 5 °C Refrigerate left and right, so as not to reduce the yield and quality of alfalfa leaf protein due to the action of the leaf itself and microbial contamination;

[0025] (2) Cleaning, crushing, beating and juicing: Clean the alfalfa, drain the water, cut into small pieces of 0.5-1cm, add water according to the ratio of raw material: water = 1:2 by weight, and put it into a tissue masher Uniform beating, filtering and squeezing with 120-mesh nylon filter cloth to obtain alfalfa juice;

[0026] (3) Leaf protein aggregation: use a water bath to gradually increase the temperature, first raise the temperature of the alfalfa juice to 60°C, keep it warm for 6 minutes, filter or centrifuge to obtain ...

Embodiment 2

[0031] (1) processing raw material: adopt fresh alfalfa, get its top 30cm and plant blade as processing raw material;

[0032] (2) Cleaning, crushing, beating and juicing: Clean the alfalfa, drain the water, cut into small pieces of 0.5-1cm, add water according to the ratio of raw material: water = 1:2 by weight, and put it into a tissue masher Uniform beating, filtering and squeezing with 120-mesh nylon filter cloth to obtain alfalfa juice;

[0033] (3) Leaf protein aggregation: use a water bath to gradually increase the temperature, first raise the temperature of the alfalfa juice to 60°C, keep it warm for 6 minutes, filter or centrifuge to obtain green fodder leaf protein aggregates; then heat the filtrate or supernatant to 80°C, keep warm 6min, filter to obtain white edible leaf protein aggregate;

[0034] (4) Separation of leaf protein aggregates: use filter cloth to filter, so that edible leaf protein aggregates and forage leaf proteins are separated from water respecti...

Embodiment 3

[0038] (1) Processing raw materials: use fresh alfalfa, take its top 30cm and plant leaves as processing raw materials, alfalfa should be processed as soon as possible after harvesting, if it needs to be stored for a short time, it should be sealed in a fresh-keeping bag and placed at 5 °C Refrigerate left and right, so as not to reduce the yield and quality of alfalfa leaf protein due to the action of the leaf itself and microbial contamination;

[0039] (2) Cleaning, crushing, beating and juicing: Clean the alfalfa, drain the water, cut into small pieces of 0.5-1cm, add water according to the ratio of raw material: water = 1:2 by weight, and put it into a tissue masher Uniform beating, filtering and squeezing with 120-mesh nylon filter cloth to obtain alfalfa juice;

[0040] (3) Leaf protein aggregation: use a water bath to gradually increase the temperature, first raise the temperature of the alfalfa juice to 60°C, keep it warm for 6 minutes, filter or centrifuge to obtain ...

Abstract

The invention discloses an extraction method for directly separating feed or edible leaf protein of clover and relates to an extraction method of leaf protein of clover; the extraction method of the leaf protein of the clover comprises the following steps: the edible leaf protein needs to be processed secondarily, decolorized and fishy removed, the technology of decolorization and fishy smell removing of the leaf protein of the clover is still in the researching stage and the technique is not mature; the invention provides an extraction method for directly separating the feed or edible leaf protein of clover, which comprises the following steps: material processing, cleaning, chopping, beating, juicing, leaf protein concentration, condensate separation of leaf protein, drying and storing; and the extraction method of the invention can directly separate the feed or the edible leaf protein of clover without needing the technique of decolorization and fishy smell removing, and the like.

Description

technical field [0001] The invention relates to a method for extracting alfalfa leaf protein, in particular to an extraction method for directly separating alfalfa leaf protein for feeding and eating. Background technique [0002] Alfalfa leaf protein (LPC) is a high-grade alfalfa deep-processing product. It is separated and purified to obtain two kinds of food and feed leaf protein products with different uses and different values. Among them, edible leaf protein is a kind of low-fiber, low-fat, and cholesterol-free protein source, which is more suitable as a health product for children, anemia patients, pregnant women, hyperlipidemia patients and the elderly, and can also be used as an extraction raw material for some medicines. It can also be used in cosmetics and daily chemical industry. Feed leaf protein can provide a rich source of plant protein for the feed industry. At present, the alfalfa leaf protein produced in my country can only be used as plant protein for fe...
