Abstract

The invention relates to the field of fruit processing and discloses Actinidia arguta Sieb.et Zucc. freeze-dried powder and a standard thereof. A pre-cooling process comprises putting a device with Actinidia arguta Sieb.et Zucc. paste into a refrigerating chamber, carrying out pre-freezing at a pre-freezing temperature of -35 DEG C for 10h until the core temperature of the Actinidia arguta Sieb.et Zucc. paste is -40 DEG C, and keeping the temperature for 2-6h so that the pre-cooling process is finished. A vacuum freeze-drying process comprises feeding the pre-frozen Actinidia arguta Sieb.et Zucc. paste into a drying cabin, starting a vacuum pump, keeping vacuum pressure of 1-20pa, slowly heating the Actinidia arguta Sieb.et Zucc. paste to -30 DEG C at a heating rate of 1 DEG C/h, keeping the temperature for 12h, slowly heating the Actinidia arguta Sieb.et Zucc. paste to -5 DEG C at a heating rate of 2 DEG C/h, keeping the temperature for 8h so that a first drying stage is finished, on the premise of enzyme activity guarantee, slowly heating the Actinidia arguta Sieb.et Zucc. paste to 40 DEG C at a heating rate of 3 DEG C/h, keeping the temperature for 8h and taking the Actinidia arguta Sieb.et Zucc. paste out of the cabin. The Actinidia arguta Sieb.et Zucc. freeze-dried powder has small nutrition loss and good fruit powder processing effects and is suitable for being eaten in different seasons. The Actinidia arguta Sieb.et Zucc. freeze-dried powder has scientific and reasonable quality indexes and gets the guarantee.

Description

technical field [0001] The invention relates to the field of fruit processing, namely the freeze-dried powder of wild jujube and its standard. Background technique [0002] Wild soft jujube (Actinidia arguta Sieb. et Zucc.), commonly known as soft jujube and round jujube, belongs to the perennial deciduous vines of Actinidiaceae and Actinidia genus. It is widely distributed in the Changbai Mountain area in Northeast my country and has rich reserves. Unique flavor, sweet and sour taste, rich in nutrients, the pulp contains a variety of vitamins, of which vitamin C can be as high as 4mg / g, which can be called the king of fruits. At the same time, it contains more than 20 kinds of trace elements and 20 kinds of amino acids. The total content of various amino acids can reach 10mg / g. The function of fire can prevent and treat constipation and hemorrhoids; improve blood flow and prevent the formation of thrombus; regulate sugar metabolism, regulate intracellular hormones and ner...
