Description

A kind of frozen that adds the blueberry leaf extract and preparation method thereof
Technical field
The present invention relates to the frozen manufacture field, particularly, the present invention relates to a kind of frozen that adds the blueberry leaf extract and preparation method thereof.
Background technology
At present, the frozen of supplying on the market of a great variety, frozen product; Especially ice cream; Because its abundant and fragrant sliding careful mouthfeel has attracted a lot of consumers, account for a part bigger in the frozen, but the frozen that contains the health-care efficacy component lacks relatively on market.
Blueberry is born in hillside, roadside or the bushes, is the aithullium seeds, summer leaf color jade green, autumn, the leaf look little was red, height of tree 1m~3m, multi-branched, branch is thin, ash is redly brown, sprout has the fine and soft hair of taupe.The leaf keratin, avette, the narrow ellipse of ellipticity or avette, long 2.5~6 centimetres, wide 1~2.5 centimetre, the anxious point in top, the edge has sparse sharp sawtooth, and the base portion wedge-like is glossy, how many thin undercoats of giving birth to of Zhong Mai two sides; Petiole is short and not obvious, and Yangze river and Huai river one band is whenever adopted leaf in cold food festival and boiled into black meal, so the name blueberry.
The chemical composition that contains in the blueberry leaf has hentriacontane, freidelin (ketone), epifriedelanol, cupreol and ursolic acid 、 Quercetin, homo-orientin, hydroxycinnamic acid, meso inositol, malol, oleanolic acid.Also contain rich in amino acid and organic acid in addition in the leaf.Organic acid is mainly oxalic acid, tartaric acid, citric acid and butanedioic acid.Sugar mainly is glucose, sucrose, maltose and fructose or the like.The fatty acid material has 6 kinds: brown eleostearic acid, stearic acid, oleic acid, linoleic acid, leukotrienes, arachidic acid.
Blueberry leaf basis is: protein 3.02%, fat 0.8%, total reducing sugar 53.2%, moisture 7.3%, general flavone 3.42%.
Blueberry leaf has good dietary function:
A, antidotal effect: animal experiment shows that the blueberry leaf extract can significantly improve the balance of movement and the coordination ability of old mouse, strengthens the short term memory capacity of mouse.
The effect of B, anti-cancer and cancer-preventing: bring out cancer thereby free radical can destroy dna molecular, and anti-oxidant can play in metabolic processes in the effect of the free radical that produces, blueberry contains abundant anthocyanin class flavones, can suppress the generation of free radical.
C, to the protective effect of eyes: clinical research finds that it has good result of treatment to multiple ophthalmology disease, as activating the retina enzyme, promotes the synthetic of rhodopsin, improves half-light eyesight down, treats yctalopia etc.
D, antitussive effect: contain De Quercetin, ursolic acid in the blueberry leaf, and some flavones has significant antitussive action.
The present invention adds the blueberry leaf extract on the basis of the original prescription of frozen, because the blueberry leaf flavor is flat bitter, has antidiarrheal to remove after taking and sleep; Effects such as strong muscle benefit strength; And its extract has good colorability, be worth excavating for its utilization on frozen, but owing to the frozen bitter taste that has added blueberry leaf is overweight; How to guarantee the coordination of frozen taste, the pre-treatment of blueberry leaf with and to select addition be the problem that the present invention solves emphatically.
