Technical Field

The invention relates to the field of functional food preparation, in particular to mixed functional golden yellow flour which is prepared by taking wheat flour and cordyceps militaris aqueous extract as main raw materials according to a proper matching ratio, and a bread product which is prepared by fermenting the flour with auxiliary materials in a certain proportion.

Background

With the improvement of living standard of people, the demand of people for functional food is increasing. At present, various functional foods are endlessly layered, but most of the functional foods are used as supplementary foods rather than staple foods, and only the functional properties are emphasized, while the influence of the appearance on the consumption desire of consumers is ignored. Therefore, the staple food product with multiple biological functions, unique appearance and certain aesthetic function is developed, and the staple food product has a wide market prospect.

Wheat is a staple food commonly used in daily life and is also a main industrial raw material, and is a main starch food raw material, and wheat flour can be used for making various foods with different flavors, such as noodles, cakes, bread and the like.

The cordyceps militaris is also called golden grass, and is congeneric with the cordyceps sinensis, the fruiting body of the cordyceps militaris is golden yellow, the color is full, and the appearance is attractive. The Cordyceps militaris contains main active ingredients such as Cordyceps polysaccharide, cordycepin, cordycepic acid, nucleoside, superoxide dismutase, sterols and the like, and also contains various proteins, amino acids essential to human bodies, various trace elements such as calcium, zinc, sun drying, copper, manganese, phosphorus and the like, palmitic acid, linoleic acid and the like. Cordyceps militaris is a famous traditional edible and medicinal fungus in China, and has attracted wide attention due to the application of various physiological activities in the medical field. In the well-known traditional Chinese medicine record, cordyceps sinensis has significant pharmacological activity in treating certain diseases. Is generally used for supplementing kidney and relieving lung cancer, hyperglycemia, hyperlipidemia, enhancing immunity, improving sexual function, renal dysfunction and liver diseases.

At present, most of cordyceps militaris related functional foods are developed into complementary food products, such as cordyceps oral liquid, cordyceps kidney-tonifying wine, cordyceps healthy beer, cordyceps capsules, cordyceps health-care soft sweets, buccal tablets, cordyceps nutrition and health-care jelly, cordyceps militaris beverage and the like. Therefore, the cordyceps militaris is used as a functional factor, partial technical support is provided for developing functional foods, and the development of related main food functional products of cordyceps militaris water extract is only related to cordyceps sinensis bread developed by using cordyceps militaris fruiting body powder as a raw material, such as Jiangzhi, and cordyceps sinensis bread developed by using N6- (2-hydroxyethyl) adenosine as a functional component, such as Chaiyouqiu, wherein the cordyceps militaris fruiting body powder is insoluble in water and possibly influences the taste of flour products, and the N6- (2-hydroxyethyl) adenosine has a single function, does not have the unique gold color of cordyceps militaris, and does not have aesthetic property. Therefore, the main food cordyceps militaris functional food which meets the requirements of taste and functional characteristics and aesthetic characteristics of the cordyceps militaris aqueous extract at the same time still needs to be developed and researched.
