Abstract

The invention belongs to the field of plant extraction, and particularly relates to an antioxidant containing an Macadamia ternifolia F. Muell green peel extract, a preparation method and applications thereof. According to the present invention, the dried Macadamia ternifolia F. Muell green peel is crushed, an organic solvent is adopted to extract, the extraction solution is subjected to solvent recovery to obtain the green peel extract, a proper solvent is adopted to disperse the green peel extract to obtain the antioxidant containing the Macadamia ternifolia F. Muell green peel; the antioxidant can be used for increasing the oxidation effects of greases, cosmetics, fruit wine, fruit juice, fried foods, meat products and other products so as to prolong the shelf life; and the technology is easy to operate, and the product is widely used.

Description

technical field [0001] The invention belongs to the field of plant extraction, and in particular relates to an antioxidant containing macadamia nut green bark extract, a preparation method and application thereof. Background technique [0002] Macadamia ternifolia F.Muell is a dicotyledonous evergreen tree of the Proteaceae family (Proteaceae), native to the subtropical rainforests of Queensland and New South Wales, Australia. Because of its unique flavor and rich nutritional content, it is considered by overseas as one of the best table nuts in the world, and has the reputation of "Queen of Dried Fruits"; it has developed into one of the four famous nuts in the world. [0003] Macadamia nuts were introduced to China in the 1960s and 1970s. In recent years, it has been planted on a large scale in my country's Yunnan, Guangxi, Guangdong and other provinces and cities, forming a preliminary industry (total planting area of ​​about 200,000 mu). In the whole fruit harvested fr...
