The invention discloses a method for producing black tea through artificial intelligence enzymatic fermentation. The method has the advantages as follows: (1) the preparation process for producing high-quality black tea is a mechanical, intelligent and biological fermentation preparation process; (2) mechanical equipment configured for the process is energy-saving and environment-friendly, so that the economic, social and ecological benefits are significant; (3) the process integrates a computer intellectual technology to the field of black tea processing, so that a new high-tech process technology is initiated for black tea processing in China; (4) a glucoamylase enzymatic biological fermentation technology in the method disclosed by the invention optimizes the quality of the black tea and increases the nutritional function of the black tea; (5) a microwave sterilization process of the method discloses by the invention thoroughly kills all harmful organisms to ensure the quality safety of a product.

The invention provides a greenhouse hot pepper autumn postponing overwintering in field fresh retaining cultivation method. By adopting steps of cultivation condition selecting, seedling cultivating method, field planting, cultivation and management, preventing plant diseases and insect pests, harvesting and the like, a supply period of normal open ground autumn red hot pepper is postponed from original middle to late October to December until April of the following year, and hot peppers are successively in market. A greenhouse hot pepper cultivating technology is efficient, anti-season and characteristic, and further has the advantages of being simple to implement, strong in operability, wide in adaptability, and capable of meeting requirements for the hot peppers in a slack season of long winter and early autumn. Not only red hot pepper featured products achieve slack season peak shifting in mark, but also advantages of in field fresh retaining and opportunity and time selecting marketing are possessed, and thus economic benefit is very outstanding and stable. Besides, integrated application of green prevention and control measure on diseases, insect pests and weeds is paid attention to various stages of seed selection, seedling culturing and cultivation, use of agricultural chemical is prevented and reduced to the largest extent, and product quality and safety are guaranteed reliably.

The invention relates to the technical field of snow chrysanthemum extraction, and relates to a snow chrysanthemum extract and a preparation method thereof. The snow chrysanthemum is obtained according to the following preparation method: the first step, enzymatic extraction; the second step, filtering; the third step, using 0.3μm to 0.5μm pore size membrane microfiltration; the fourth step is to use membrane ultrafiltration with a molecular weight cut-off of 10000D to 500000D; the fifth step is to use a membrane with a molecular weight cutoff of 200D to 1000D for ultrafiltration; the sixth step is to The snow chrysanthemum extract is obtained after drying. Adopting the method of the present invention to extract dry matter from snow chrysanthemum has a high yield, and can effectively reduce cost and energy consumption. After microfiltration or ultrafiltration treatment by membrane separation process, the amount of macromolecular substances is reduced, and the filtrate is stored during storage. No flocculent precipitation is produced, the loss of active ingredients is also reduced, the product quality is improved, and the product quality and safety are guaranteed.
