Functional brewing rice flour based on waste cordyceps militaris culture medium and preparation method of functional brewing rice flour

Abstract

The invention belongs to the technical field of agricultural and sideline products and food, and discloses functional brewing rice flour based on a waste cordyceps militaris culture medium and a preparation method of the functional brewing rice flour, and a cordyceps militaris culture technology is optimized by taking the appearance of the culture medium after sporocarp harvesting and the quantity of impurities as indexes; a pretreated waste culture medium is used as a main raw material, and raw material ratio, material water content, screw rotation speed and puffing temperature are used as investigation factors, so that an extrusion puffing production process of the brewed rice flour is optimized; a sensory evaluation system is established and utilized, and a compounding formula of the rice flour is optimized and determined; the preparation process of the edible independent small package is determined, the eating convenience of the product is improved, and the package of the product is improved; pollutants, nutrients and functional components of the rice flour finished product are determined; and safety hazards and key control points are determined, and an HACCP system is established. According to the rice flour, the health-care function and food safety of the product can be ensured, and multiple problems of waste, pollution and the like in the fields of agriculture, environment, food and the like can be solved.

Description

technical field [0001] The invention belongs to the technical field of agricultural by-products and food, and in particular relates to a functional brewed rice flour based on a waste Cordyceps militaris cultivation substrate and its preparation. Background technique [0002] At present, more than 60% of the population in my country takes rice as the staple food. Rice has high nutritional value. It can not only provide the human body with nutrients such as sugar, protein, fat and dietary fiber, but also provide the human body with iron, manganese, copper, Trace elements such as zinc and calcium. Rice protein is the best among cereal proteins. It has the characteristics of no pigment interference, low antigenicity, no irritating taste, and high digestibility. At the same time, rice protein also has the effects of lowering cholesterol, lowering blood pressure, and anti-oxidation. Therefore, rice is an ideal raw material for developing functional foods. In recent years, the con...

Problems solved by technology

[0006] (1) At present, there is no complete set of relevant technologies for further processing waste Cordyceps militaris cultivation substrates and developing them into functional foods

[0007] (2) In the existing commercial production of Cordyceps militaris, the value of the cultivation substrate is underestimated, and it is discarded or produced as feed, resulting in waste of resources and pollution to the environment

Therefore, when developing and utilizing these materials, the R&D and integration of related technologies must be carried out under the premise of ensuring the nutritional quality and health functions of the products, which is relatively difficult.

[0010] (2) With the continuous expansion of the market demand for Cordyceps militaris, the increase in production capacity has brought greater pressure on environmental protection, and there is a certain contradiction between the two. How to solve these two problems at the same time through one technology is relatively more difficult
