by:CBFI     2020-10-11
Common freeze-dried anthocyanin mainly through the lyophilizer and superfine grinding equipment and system, start with raspberries with extremely high content of anthocyanins, berries, mulberries, blueberries, raspberries, black currants, indigo fruit, black Chinese wolfberry, black Chinese wolfberry, red Chinese wolfberry, cranberry, etc as the raw material, through the beneficial bacteria fermentation at low temperature and low temperature drying and the lyophilizer superfine grinding equipment in low temperature crushing.

the lyophilizer vacuum freeze drying process was conducted under 0 ℃, namely in fruit frozen state. Under the condition of vacuum, when water vapor directly to sublimation, berries and active substances left in freeze when ice shelf, forms a spongy porous structure, so it is dry after size is almost the same. Due to drying under vacuum, oxygen is few, so easy oxidation of some substances in berries have been protected. And maximum limit retained powder of bioactive ingredients, made the required for high quality products. After bring of the fruit of freeze-dried superfine grinding, as quickly and is easy to be absorbed by human body bowel function in human body.
