Description
Technical field
The present invention relates to the extractive technique field of Anthocyanin, specifically a kind of extraction side of pitaya peel anthocyanidinMethod.
Background technology
Dragon fruit is common a kind of fruit, and dragon fruit is nutritious, and meat exquisiteness is subject to everybody liking deeply, and we are eatingWhen dragon fruit, generally pericarp can be thrown away, the pericarp nutritive value of dragon fruit is high in fact. In pitaya peel, contain ash content,Crude fat, crude protein, crude fibre, vitamin C, calcium, phosphorus, iron and lot of anthocyanin, water-soluble meals albumen, phytalbuminDeng. The pericarp of dragon fruit contains the nutriment-anthocyanidin being of great rarity. Anthocyanidin is a kind of antioxidant of brute force, is better thanCarrotene is more than 10 times, and can in blood of human body, preserve active 75 hours. It can protect human body avoid harmful substance-fromBy the damage of base, contribute to prevent the multiple disease relevant with free radical. Anthocyanidin can strengthen blood vessel elasticity, protection arterial bloodInside pipe wall; Reduce blood pressure; Promote the smoothness of skin, U.S. face skin; Inflammation-inhibiting and allergy, improve the pliability in joint, pre-Anti-arthritis; Can promote the visual purple regeneration in retina cell, improve eyesight; Also there is radiation-resistant effect etc. And it is fieryThe skin of dragon fruit is often abandoned as refuse, and applicant prepares anthocyanidin by the pitaya peel to discard as raw material, reachesTo waste reclamation.
Summary of the invention
The object of the present invention is to provide a kind of extracting method of pitaya peel anthocyanidin, to solve in above-mentioned background technologyThe problem proposing.
For achieving the above object, the invention provides following technical scheme:
An extracting method for pitaya peel anthocyanidin, comprises the following steps:
Step 1, pitaya peel powder preparation: pitaya peel slag heated constant temperature after washing is dry, then uses plant pulverizer powderBroken mistake 60～80 mesh sieves are collected powder, are pitaya peel powder;
Step 2, nitrogen protection: the pitaya peel powder of step 1 is placed in extraction kettle, adds 1% citric acid and 90% secondAlcohol is as extracting solvent, and their volume ratio is 3:28, fully mixes, and uses vavuum pump deoxidation, then passes into pure nitrogen gas;
Step 3, Microwave Extraction: pass into after nitrogen, and after alcohol solution dipping, adopt microwave to extract 2 times, merge 2The inferior pitaya peel solution that contains residue of obtaining, obtains extract after filtration;
Step 4, separate: by separator by the pitaya peel solution that contains residue in step 3 filter, centrifugal, discardFilter residue, obtains supernatant;
Step 5, concentrate drying: step 5 gained is carried out to concentrated frozen and be dried, vacuum keep is being 25Pa, continues 2h,To pitaya peel anthocyanidin.
As preferred version of the present invention, the dry temperature of heated constant temperature described in step 1 is 65～70 DEG C.
As preferred version of the present invention, the aridity that a kind of described freeze-day with constant temperature of step reaches is 93～95%.
As preferred version of the present invention, the Microwave Extraction in described step 32 times, microwave irradiation time is for the first time80s, extraction time is 60s for the second time.
In sum, the invention has the beneficial effects as follows: the present invention is to leaching process, taking ethanol and citric acid mixed solution asExtract solution, have pollution-freely, cost is low, the advantage of nonhazardous; Adopt Microwave Extraction, safe and reliable, promote active ingredientExtraction, simple to operate, extraction time is short, recovery rate is high, target component purity is higher and save energy consumption, improves the profit of resourceBy rate. The present invention has that technique is simple, the rate of recovery is high, oxidation loss is little, when joint, energy-conservation, recovery rate advantages of higher, avoid simultaneouslyThe use of toxic solvent, there is good industrial promotional value. Pass into pure nitrogen gas, ultrasonic extraction is obtained to oxidizable fluePericarp anthocyanidin is protected, and significantly improve, and quality of finished is high in this condition leaching rate. Utilize method of the present invention, extractPitaya peel anthocyanidin, one time recovery rate just can reach more than 80%, and purity reaches more than 91.85%.
