Problems solved by technology

[0003] In the prior art, hemp seed health food and Chinese patent medicine preparation all directly use hemp seed as raw material, but because hemp seed contains rich oil (oil content 32%~40%), the processed product Easy to oxidize and deteriorate
However, the traditional methods of protein extraction such as separation and extraction by hydrolysis pulping, mechanical degreasing after steaming or roasting, leaching and extraction with ethanol, ether or n-hexane, hydrolysis distillation concentration and spray drying all have protein aging and denaturation due to high temperature treatment. defect

Embodiment 1

[0021] Hemp seeds with a protein content of 20.84% ​​and an oil content of 38% are used as raw materials. After screening to remove organic and inorganic impurities and magnetic separation to remove metallic impurities, the processed hemp seeds are processed in a fluidized tank dryer at 80°C. The hemp seeds are heated for 3 minutes, and then quickly cooled by natural cold wind outside the workshop for 3 minutes. After the rapid heating and cooling, the hemp seeds are mechanically hulled and crushed, and the two-stage screening and air selection are combined to separate the shell kernels and return to the machine for repeated hulling. Grind unhulled kernels, and directly use mechanical cold pressing to separate part of the oil from the hulled hemp kernels and make shelled hemp kernel protein embryo flakes with an oil content of ≤18%.

Embodiment 2

[0023] Repeat Example 1, with the following differences: after heating the raw material at 75° C. for 5 minutes, the natural cold wind outside the workshop was used for rapid cooling for 5 minutes.

Embodiment 3

[0025] Put the dehulled hemp seed protein germ slices that embodiment 1 makes into extraction tank, adopt butane as solvent to extract the fat in the germ slices and isolate the protein in the germ slices, when extracting the fat in the germ slices and separating the protein, the temperature ≤45℃, after 5 repeated cycles of extraction and separation, the degreased edem protein wet meal is obtained. The wet meal contains about 30% solvent, and it is decompressed and gasified to reach 0Mpa (gauge pressure).

[0026] Example 3

[0027] Repeat Example 2, with the following differences: propane is used as the solvent to extract the oil in the embryonic slices and to isolate the protein in the embryonic slices.

Abstract

A hemp seed protein powder is prepared from hemp seeds through removing impurities, classifying, quick heating, quick cooling, mechanical peeling, cold squeezing, separating protein flakes from oil, extracting and separating protein 4-6 times, vacuum evaporating to remove solvant, pulverizing and screening.

Description

technical field [0001] The present invention relates to the development and utilization of hemp seed, more specifically, the present invention relates to a kind of hemp seed protein powder, meanwhile, the present invention also relates to a kind of preparation method of said hemp seed protein powder and its application in food application. Background technique [0002] Hemp seed, commonly known as hemp seeds, hemp seeds, and hemp seeds, is one of the commonly used medicinal materials and health food raw materials in Chinese medicine. The 2000 edition of "Pharmacopia of the People's Republic of China" listed "the dry and mature fruit hemp seed of Moraceae plant cannabis (Cannabissativa L.)" in the Pharmacopoeia, and the Ministry of Health of the Ministry of Health issued [2002] No. 51 document "Ministry of Health on further standardizing Notice on the Management of Health Food Raw Materials, which included hemp seed in the "list of items that are both...
