Embodiment 1

[0014] Take 100 kg of fresh soybean leaves and put them into a vacuum tank, add 500 kg of 100% ethanol and seal it, heat up to 60°C, stir at 30 rpm for 10 minutes to extract, filter the extract with a 60-mesh sieve, and pump Enter another vacuum concentration tank to reclaim ethanol, and return it to the extraction tank after passing through a buffer tank, repeat the previous step, so until the leaves are green, vacuumize to a vacuum degree of 0.85 Torr, and desolventize for 10 minutes. Decolorized and presolventized leaves are obtained; the decolorized and presolventized leaves are crushed and passed through a 100-mesh sieve to remove crude fibers to obtain leaf protein.

Embodiment 2

[0016] Take 200 kilograms of fresh potato leaves and put them into a vacuum tank, add 300 kilograms of 85% ethanol and seal it, heat up to 50°C, stir at 35 rpm for 12 minutes to extract, filter the extract with a 90-mesh sieve, and pump Enter another vacuum concentration tank to reclaim ethanol, and return it to the extraction tank after passing through a buffer tank, and repeat the previous step until the leaves are completely green, vacuumize to a vacuum degree of 0.90 Torr, and desolventize for 60 minutes. Obtain the leaves after decolorization and precipitation; crush the leaves after decolorization and precipitation, and pass through a 600-mesh sieve to remove crude fibers to obtain leaf protein.

Embodiment 3

[0018] Get 300 kilograms of dried pickled mustard leaves and put them into a vacuum tank, add 3000 kilograms of 95% propanol and seal them, heat up to 80°C, and stir at 40 rpm for 15 minutes to extract, filter the extract with a 120-mesh sieve, Pump into another vacuum concentration tank to recover propanol, and return it to the extraction tank after passing through a buffer tank, repeat the previous step, so until the leaves are green, vacuumize to a vacuum degree of 0.96 Torr, and desolventize at 120 Minutes to obtain the leaves after decolorization and precipitation; crush the leaves after decolorization and precipitation, and pass through a 1200 mesh sieve to remove crude fibers to obtain leaf protein.

Abstract

The production method of edible protein by using plant leaf includes the following steps: using ethyl alcohol or propyl alcohol to remove nutrient-resistance factors of chlorophyll, alkaloid and saponin from plant leaf, pulverizing and sieving to obtain the invented leaf protein. Said method is safe and non-toxic, the yield rate of whole leaf protein can be up to above 80%, and the protein content in the product can be up to above 45%.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a method for producing edible protein by using plant leaves. Background technique [0002] Studies have shown that the protein content in plant leaves is very high, accounting for more than 20% of the dry matter weight of the leaves. At the same time, many plant leaf proteins are not only high in nutritional value, but also non-toxic, completely safe for human consumption. But, except that some are used as the plant leaves of vegetables, other crop leaves such as bean leaves, sugar beet leaves, potato leaves, hemp leaves, pickled mustard leaves and radish leaves, most of them have not been well utilized. In addition, for some plants, the protein yield per mu is much higher than that of soybeans and other seeds, such as clover, which can produce more than 0.5 tons of protein per mu, and water hyacinth and water floating lotus, whose protein yield can reach more than 1 ton per mu. ...
