Abstract
The present invention relates to an edible protein producing method using plant leaves, which comprises the following steps: the anti-nutrition factors such as chlorophyll, alkaloid, saponin, etc., of plant leaves are removed by etanol or propyl alcohol; the plant leaves are pulverized and sieved to obtain leaf protein. The method has the advantages of high safety and innocuity. The yield of all leaf protein reaches more than 80 percents, and the protein content of products reaches more than 45 percents.
Description
The present invention relates to food processing field, particularly relate to a kind of method of utilizing plant leaf blade to produce edible protein.
Studies show that the protein content in the plant leaf blade is very high, account for more than 20% of blade dry matter, simultaneously, not only nutritive value is very high for a lot of plant leaf proteins, and nontoxic, fully can be edible for human security.But except some were used as the plant leaf blade of vegetables, other was as crops blades such as beans leaf, beet tops, potato leaf, numb leaf, mustard leaf and radish leaves, and great majority fail well to be utilized.In addition, some plant, its protein per mu yield is far above seed albumen such as soybean, clover for example, its per mu yield albumen can reach more than 0.5 ton, and for example water hyacinth, water lettuce, its per mu yield albumen can reach more than 1 ton.
Up to the present, about the production method of leaf protein matter, following youngster's class is arranged: the first kind is earlier blade to be squeezed the juice, and extracts the green portion that can make feed and the protein that can make food additives then from juice; Second class is with the complete post precipitation of the protein in the juice, with the chlorophyll in the organic solvent wash-out sediments such as propyl alcohol; The 3rd class is with after the bright leaf chopping, with producing protein concentrate behind the direct wash-out chlorophyll of methyl alcohol.Said method exists significantly not enough, and the yield of preceding two kinds of method protein is lower, and the methyl alcohol that the third method is used is poisonous.
The object of the present invention is to provide a kind of safety non-toxic, utilize plant leaf blade to produce the method for edible protein efficiently.
The present invention realizes successively through the following steps:
(1) a or b step are finished blade decolouring, detoxification by descending
A puts into a vacuum tank with plant leaf blade, seal after adding 85～100% heavy ethanol of 1.5～10 times of leaves or propyl alcohol, be warming up to 50～80 ℃, extracted in 10～15 minutes with 30～40 rev/mins of stirrings, after extract filtered with 0.250 millimeter～0.125 millimeter mesh sieve, reclaim ethanol or propyl alcohol in another vacuum concentration pot of suction, and it is returned extractor after by a surge tank, repeat last step, so till leaf green takes off to the greatest extent, being evacuated to vacuum is 113.32～127.99 Pascals, and precipitation 10～120 minutes must decolour, blade behind the precipitation;
B puts into the infuser that grease leaches system with plant leaf blade, with 1.5～10 times of leaves heavy 85～100% ethanol or propyl alcohol, carries out extracting under 50～80 ℃ of temperature conditions, to green take off use up till, precipitation must decolour, the blade behind the precipitation;
(2) will decolour, the blade behind the precipitation pulverizes, cross 0.149 millimeter～0.01 mm sieve and remove crude fibre, leaf protein matter.
Above-mentioned plant leaf blade can be bright leaf or cured leaf, can be blade of Folium Glycines, potato leaf, mustard leaf, numb leaf, radish leaves, beet tops, water hyacinth or water lettuce and other plant etc.
It can be flat turn type, satellite-type, loop type or pot group type grease leaching system etc. that grease leaches system.
Advantage of the present invention is, owing to use the extraction of ethanol or propyl alcohol, so safety non-toxic, simultaneously, this method can be sloughed chlorophyll fully, substantially remove the ANFs such as alkaloid, phenolic compound and saponin in the blade, the yield of full leaf protein matter reaches more than 80%, and protein content reaches more than 45% in the goods.
