A kind of bisporus seabuckthorn instant tea and preparation method thereof

Abstract

The invention provides agaricus bisporus and hippophae rhamnoides instant tea, and belongs to the technical field of processing of instant tea products. The agaricus bisporus and hippophae rhamnoides instant tea provided by the invention is powdery agaricus bisporus and hippophae rhamnoides instant tea prepared through the following steps of mixing an agaricus bisporus aqueous extracting solution with a hippophae rhamnoides leaf aqueous extracting solution, performing concentration, performing liquid state fermentation through eurotium cristatum and aspergillus niger, performing filtration and performing vacuum drying. Besides, the invention further provides a preparation method of the agaricus bisporus and hippophae rhamnoides instant tea. The preparation method specifically comprises the following steps of performing aqueous extraction on hippophae rhamnoides leaves so as to obtain a hippophae rhamnoides leaf aqueous extracting solution, performing aqueous extraction on pretreated agaricus bisporus so as to obtain the agaricus bisporus aqueous extracting solution, and mixing the hippophae rhamnoides leaf aqueous extracting solution with the agaricus bisporus aqueous extracting solution so as to obtain an agaricus bisporus and hippophae rhamnoides mixed solution; performing concentration; performing UHT sterilization; preparing an eurotium cristatum seed solution and an aspergillus niger seed solution; performing inoculation of mixed bacteria and fermentation twice; performing centrifugation; performing membrane filtration; and performing drying. According to the agaricus bisporus and hippophae rhamnoides instant tea and the preparation method thereof disclosed by the invention, the fermentation efficiency of bacterial strains is improved, bitter taste in the hippophae rhamnoides tea is eliminated, mannose, trehalose and various amino acid substances in the agaricus bisporus are reserved, the content of nutrient components is high, and the preparation method is suitable for mass production.

Description

technical field

[0001] The invention belongs to the field of instant seabuckthorn tea processing, in particular to a bisporus seabuckthorn instant tea and a preparation method thereof. Background technique

[0002] The meat of Agaricus bisporus is fat and tender, and contains more mannose, trehalose and various amino acid substances, so it is delicious and nutritious. It is determined that every 100g of dried mushrooms contains 36-40g of protein, 3.6g of fat, and carbohydrates. 31.2g, 718mg of phosphorus, 188.5mg of iron, 131mg of calcium, 14.2mg of ash, 6g of crude fiber, in addition, it also contains vitamin B1, B2, Vc, niacin, etc., because its nutrition is higher than that of ordinary vegetables, so it has "vegetable meat" known as.

[0003] Sea buckthorn (Latin scientific name: Hippophae rhamnoides Linn.) is a deciduous shrub, which is characterized by drought tolerance, wind and sand resistance, and can survive on salinized land, so it is widely used in water and soil...
