Preparation method for separating auricularia auricula into auricularia auricula soft bone substance and auricularia auricula colloid substance

Abstract

The invention discloses a preparation method for separating auricularia auricula into auricularia auricula soft bone substances and auricularia auricula colloid substances and belongs to the field of auricularia auricula processing. According to the adopted method, the black fungus is effectively separated into the black fungus soft bone substance which is not liquefied and the black fungus colloid substance which is liquefied by utilizing the characteristic that the liquefaction speeds of the black fungus soft bone substance and the black fungus colloid substance are different in a high-temperature and high-pressure state. The result shows that the problem that the black fungus is separated into the black fungus soft bone substance and the black fungus colloid substance is simply and efficiently solved.

Description

Technical Field

[0001] The invention relates to the field of black fungus processing, and in particular to a preparation method for separating black fungus into black fungus cartilage material and black fungus colloid material. Background Art

[0002] Black fungus is a colloid fungus, which consists of mycelium and fruiting body. Mycelium is colorless and transparent, with transverse septa and multi-branched tubular structure. The space of mycelium is filled with colloid substances, which enables it to adapt to the drastic changes of dry and wet climate. Mycelium develops to a certain stage and twists into fruiting body. When the fruiting body is first born, it is soft and colloid, sticky and elastic, and then slightly cartilaginous. After drying, it shrinks strongly and becomes black, hard and brittle, horny to leathery, and can still return to its original state after absorbing water.

[0003] Black fungus cartilage and black fungus colloid are both important components of black fungus. Moreover, both parts have outstanding medicinal and edible values. There is more melanin in black fungus cartilage, and natural melanin without toxic side effects has a strong demand in food additives; black fungus colloid contains a large amount of black fungus polysaccharide, which is widely studied and applied in the medical field. Therefore, it is very necessary to separate black fungus into black fungus cartilage and black fungus colloid in a simple, convenient and fast method. Summary of the invention

[0004] The purpose of the present invention is to provide a method for preparing black fungus cartilage material and black fungus colloid material simply, quickly and in one time.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0006] Cut the soaked black fungus into blocks or strips with a width of 0.2 to 2.0 cm;

[0007] Prepare water according to the mass ratio of dry black fungus to water of 1:20 to 1:40;

[0008] Putting the soaked and cut black fungus into the prepared water and mixing to obtain a mixture of black fungus and water;

[0009] The temperature of the high-temperature pressure cooker is adjusted to 80-120°C, the pressure is adjusted to 70-140KPa, and the time is adjusted to 3-12 hours to process the mixture of black fungus and water;

[0010] The black fungus material processed in the high-temperature pressure cooker is separated by a sieve with a diameter of 0.1 to 1.0 cm to obtain black fungus cartilage material and black fungus gelatinous material.

[0011] The beneficial effect of the present invention is that the present invention utilizes common natural black fungus as raw material to separate black fungus cartilage and black fungus colloid, and through the effective separation of the two substances, all parts of the black fungus can be fully and comprehensively developed. DETAILED DESCRIPTION

[0012] The technical solution of the present invention is further illustrated below through specific embodiments, but is not limited thereto. Any modification or equivalent replacement of the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention should be included in the protection scope of the present invention.

[0013] Example 1
