Embodiment 1

[0022] Embodiment 1: (method 1 for improving tea tree mushroom powder properties and improving the dissolution of some nutrients)

[0023] The method proceeds as follows:

[0024] (1) Pretreatment of the fruiting bodies of the tea tree mushroom: cut the fruiting bodies of the tea tree mushroom into 3-4cm long segments; immerse in water until fully absorbing water and swell; pack in bags and vacuumize, and set aside;

[0025] (2) Ultra-high pressure treatment: Put the pretreated vacuum bagged raw materials into high pressure equipment, use water as the medium, pressurize to 100MPa at 25°C, keep the pressure for 15 minutes and then automatically release the pressure to normal pressure; put the raw materials from the bag Take it out, dry it at 60°C and crush it to 60 mesh particles to form tea tree mushroom powder;

[0026] (3) Microwave extraction: A tea tree mushroom powder and deionized water were prepared into a suspension in a ratio of 1:30 by weight; first boiled in a wate...

Embodiment 2

[0027] Embodiment 2: (method 2 for improving tea tree mushroom powder properties and improving the dissolution of some nutrients)

[0028] In this example, step (2) is pressurized to 200 MPa in a high-pressure device for ultra-high pressure treatment; step (3) is microwave extraction at 110° C.: the remaining steps are the same as in Example 1.

Embodiment 3

[0029] Embodiment 3: (improving the method 3 of tea tree mushroom powder properties and improving the dissolution of some nutrients)

[0030] In this example, step (2) is pressurized to 400 MPa in a high-pressure device for ultra-high pressure treatment; step (3) is microwave extraction at 120° C.: the remaining steps are the same as in Example 1.

Abstract

The invention discloses a method for improving micromeritic characteristics of agrocybe aegerita and improving dissolution of part of nutrient substances, belonging to the technical field of processing of edible and medicinal fungus products. The method comprises the following steps: (1) pretreatment of fruit bodies of the agrocybe aegerita; (2) ultra-high pressure modification treatment; and (3) microwave extraction and the like, wherein the ultra-high pressure treatment enables texture and tissue of the agrocybe aegerita to change, increases the water retention ability and the expansion force, reduces the viscosity and also improves the dissolution of water-soluble proteins, polysaccharides and reducing sugars; and the microwave extraction enables ultra-high pressure powder proteins and the polysaccharides to be easier to dissolve out. The method is convenient, time-saving, energy-saving, non-toxic and green and can obviously improve the extraction rate of the polysaccharides, the proteins and other nutrient substances. The method can be popularized and applied in enterprises for processing edible and medicinal fungi.

Description

technical field [0001] The invention relates to the technical field of edible and medicinal fungus product processing, in particular to a method for changing the physical properties of tea tree mushroom powder and improving the dissolution of some water-soluble nutrients in tea tree mushroom. Background technique [0002] Tea Tree Mushroom is an edible fungus with high protein, low fat, polysaccharides, relatively high mineral content and high nutritional value. With the continuous improvement of people's living standards, unbalanced diets lead to overnutrition, which is a common problem in modern human society and "three highs and one low". Health has become people's life pursuit. Tea tree mushroom is the nemesis of "three highs and one low". Its ingredients are completely suitable for people's nutritional balance needs. Long-term consumption is expected to achieve the purpose of strengthening the body and prolonging life. say. At present, the consumption of tea tree mush...
