Preparation method of ganoderma lucidum sporocarp instant tea capable of promoting polysaccharide leaching and enhancing flavor

Abstract

According to the method, a temperature difference method is introduced into a preparation process of the ganoderma lucidum sporocarp instant tea, and after steam explosion and temperature difference method treatment are combined, the volume of a material is increased suddenly, the tissue structure of the material is easily damaged, a loose tissue structure is formed, and the taste of the ganoderma lucidum sporocarp instant tea is improved. Meanwhile, the tissues are softened by a vacuum-assisted temperature difference method, the softened tissues are extremely easy to damage and release the effective components, and the polysaccharide is also prevented from being easily browned. Through organic combination of steam explosion pretreatment and vacuum microwave hot air combined drying, an appropriate temperature and humidity environment is created, chemical reactions related to flavor improvement such as Maillard are promoted to be better carried out, and the flavor quality of the product is remarkably improved.

Description

technical field [0001] The invention relates to a preparation method of ganoderma lucidum fruiting body instant tea which promotes polysaccharide leaching and enhances flavor, and belongs to the technical field of food. Background technique [0002] With the rapid development of the economy and the continuous improvement of living standards, people's consumption concepts have also undergone tremendous changes, and now they emphasize the combination of nutrition and delicious food. More and more people are beginning to pay attention to the nutritional and health functions of food, and various functional health foods have emerged as the times require, such as products such as ganoderma lucidum fruiting bodies used in traditional medicine and food. [0003] Ganoderma lucidum, also known as "immortal grass", is a precious medicinal fungus. According to ancient books such as "Shen Nong's Materia Medica" and "Compendium of Materia Medica", Ganoderma lucidum has the functions of "b...

AI Technical Summary

Problems solved by technology

The main components of the fruiting bodies of Ganoderma lucidum are cellulose, hemicellulose and lignin, and the formation of bundle crystal structure or lignin binding layer between the three makes the fruiting bodies of Ganoderma lucidum have strong hardness, and the presence of polysaccharides in Ganoderma lucidum In the cell wall of the fruit body, the extraction time of Ganoderma lucidum polysaccharides by the traditional water, alkali, and acid extraction method is long, the energy consumption is large, the extraction temperature is high, and the long-term high temperature may cause the degradation of Ganoderma lucidum polysaccharides, making the extraction of Ganoderma lucidum polysaccharides difficult. It is difficult to achieve the ideal effect, the residue after extraction is directly thrown away, the low added value causes a great waste of resources, and the low added value greatly limits the development and utilization of the fruiting bodies of Ganoderma lucidum

[0007] Chinese patent document CN201610769462.9 discloses a polysaccharide extraction process of Ganoderma lucidum sporocarp, which uses a dry ultrafine pulverization process to crush the sporocarp of Ganoderma lucidum into particles with a particle size ranging from 250 μm to 380 μm, and then extracts it with hot water. Although this method It can improve the extraction rate of Ganoderma lucidum polysaccharide, but the grinding time is longer, and the long-time grinding is easy to cause the quality of the powder to deteriorate, and it has no effect on improving the flavor of the product.

Although this treatment method can increase the polysaccharide extraction yield and improve product flavor under certain parameter conditions, it needs higher steam explosion pressure conditions and longer pressure holding time. Although the polysaccharide yield can be improved under this condition, the The product is prone to serious carbonization reaction, which makes the product lose its commodity value, and is not suitable for processing Ganoderma lucidum tea alone.
