Embodiment 1

[0015] 1. Pretreatment of raw materials: collecting, washing and drying fresh bamboo leaves for later use;

[0016] 2 Boiling extraction: Take 300KG of pretreated bamboo leaves and put them into a multi-functional extraction tank, add 2500KG of water, heat to 98°C for 1 hour, remove the residue, and use the solution for later use;

[0017] 3 diatomite filtration: filter the above solution on a diatomite filter to obtain clarified feed liquid;

[0018] 4 Separation: The above-mentioned feed liquid is adsorbed by two different types of macroporous resin exchange columns connected in series, and the column is washed with pure water after fully adsorbed to remove polar impurities such as water-soluble sugars and pigments.

[0019] 5 Elution: add 50% alcohol into the resin exchange column to wash off the active ingredients adsorbed on the resin, and recover the alcohol eluent under reduced pressure;

[0020] 6. Spray drying: use a centrifugal spray dryer to dry the above feed liqu...

Abstract

A process for extracting the antioxidant from bamboo leaf includes such steps as washing and drying fresh bamboo leaves, boiling in water at 80-100 deg.C, filtering to obtain solution, filtering by diatomite, exchanging by resin column, eluting with alcohol, and spray drying.

Description

technical field [0001] The invention relates to a method for extracting plant effective components, in particular to a production method for extracting bamboo leaf antioxidants from bamboo leaves. Background technique [0002] The whole body of bamboo is a treasure. Bamboo leaves have a long history of edible and medicinal use in my country. They are famous heat-clearing and detoxifying medicines in traditional Chinese medicine. The use of bamboo industry has a long history, such as fresh bamboo leek, an antitussive agent of traditional Chinese medicine, etc. If the development and utilization of active ingredients of bamboo leaves are limited to the field of health care products and medicine, the promotion effect on the bamboo industry is still relatively limited, and only when they are integrated into the large food industry , its great potential will be realized. Patent No. 200310107871.5, the Chinese patent bamboo leaf antioxidant and its use...
