Processing technology of Angelica keiskei (Miq.) Koidz. submicron powder

Abstract

The invention discloses a processing technology of Angelica keiskei (Miq.) Koidz. submicron powder. After de-enzyme of fresh Angelica keiskei (Miq.) Koidz., the Angelica keiskei (Miq.) Koidz. is dehydrated by vacuum freeze-drying. The whole dehydration process is in an anaerobic and low-temperature process, so that effective nutritional ingredients of the Angelica keiskei (Miq.) Koidz. are barelynot lost, the Angelica keiskei (Miq.) Koidz. is barely not discolored, the fragrance is not lost, and the taste is kept fresh and cool. Compared with hot air high-temperature drying dehydration, the processing technology of the invention has the following advantage: product quality is greatly improved. According to the invention, the UHT sterilization box is used for heating and sterilizing the powdery material, wherein the UHT sterilization box can be used for heating powder for a short time, and the whole heating process is continuously carried out without shutdown or pausing. The UHT sterilization box is suitable for industrial production. Meanwhile, during heating, high-temperature steam can uniformly contact with the powder, so that the sterilization effectiveness is improved, and thesituation that the powder is caked and cannot be uniformly heated for sterilization during instantaneous sterilization of the powder is avoided.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a processing technology of bright leaf superfine powder. Background technique [0002] Ashitaba is also known as Ashitaba, Immortal Grass, Bazhang Grass, and has high nutritional value. It is one of the plants approved by the state for both medicine and food. It is known as "Immortal Grass" in Japan. Its stems and leaves contain a variety of vitamins , carotene, 16 kinds of amino acids and phenylene phenyl ketone and other ingredients, so it enjoys the reputation of "magic plant". Regulate endocrine, strengthen pancreas, purify blood, promote insulin secretion, remove excess cholesterol, relieve rheumatism pain, reduce liver burden, etc. Therefore, Ashitaba has become one of the important raw materials of big health products; [0003] However, in the current processing of Ashitaba products, radiation sterilization is used for sterilization. After sterilizatio...

Problems solved by technology

[0003] However, in the current processing of Ashitaba products, radiation sterilization is used for sterilization. After sterilization, the product has radiation residues, and the product has potential safety hazards. Some consumers do not accept food sterilized by radiation; moreover, some countries Strictly limit the import of food after irradiation sterilization. For the above reasons, this severely limits the expansion of the market sales scale of Ashitaba using irradiation sterilization. In order to solve this problem, the present invention provides the following technical solutions
