Abstract

The invention belongs to the field of mulberry leaf processing, and specifically relates to a process for comprehensive utilization of mulberry leaves, comprising the following steps: (1) adding 6-10 times the weight of water to the dried mulberry leaves, extracting at 80-100°C, and extracting The mulberry leaves are filtered to obtain the mulberry leaf residue and mulberry leaf extract. (2) The mulberry leaf extract is concentrated and then spray-dried to obtain the mulberry leaf extract. (3) The mulberry leaf residue is added with carbon source and nitrogen source , adjust the water content to 30-45% to obtain the compost, inoculate the Monascus species after the compost is sterilized, and then ferment, and the fermented product is dried and pulverized to obtain the mulberry leaf red yeast rice. The process of the present invention combines extraction and fermentation, on the one hand, it solves the environmental problems caused by the slag after leaf extraction; The unextracted active ingredients in mulberry leaves can be brought into the following mulberry leaf red yeast rice, so as to strengthen the function of red yeast rice.

Description

technical field [0001] The invention belongs to the field of mulberry leaf processing, and in particular relates to a process for comprehensive utilization of mulberry leaves. Background technique [0002] Mulberry leaves, also known as fairy leaves, have the effects of nourishing yin and blood, dispelling wind and heat dissipation, benefiting liver and ventilation, reducing blood pressure and diuresis, and are both food and medicine raw materials announced by the Ministry of Health. [0003] At present, a variety of active ingredients have been isolated from mulberry leaves and their efficacy has been proved: such as mulberry leaf polysaccharides (Xing Dongxu et al., Comparison of medicinal effects of hot water extraction and microwave extraction of mulberry leaf polysaccharides and a preliminary study on the mechanism of hypoglycemia, Sericulture Science, 2008 Issue 03), glycosidase inhibitor 1-deoxynojirimycin (DNJ), gamma-aminobutyric acid (GABA) with the function of reg...
