Abstract
The invention relates to a purple corn, particularly relates to a technology for extracting anthocyanin from purple corn and belongs to the technical field of food processing. According to the extracting technology disclosed by the invention, the purple corn is used as a raw material. The anthocyanin is extracted by various extracting technologies using different extracting agents. The different solvents have own advantages and defects as follows: an aqueous solution is suitable in price, but limited in extraction efficiency; and furthermore, a final product is obtained by using the aqueous solution with consuming a great amount of energy; because the anthocyanin is stable and easy to extract under a per-acid condition, an acidulated solution has the increased extraction efficiency compared with the aqueous solution, but the acylated anthocyanin is partially or entirely hydrolyzed due to the acidulated solution in evaporation concentration and a great amount of salts can be formed in the product, thereby reducing the product purity; and the extraction efficiency of the anthocyanin can be greatly improved by the acidulated alcohol, and the alcohol can be further recycled and utilized, thereby reducing the extraction cost.
Description
Technical field
The present invention relates to a kind of purple corn, be specifically related to a kind of extractive technique of purple corn anthocyanin, belong to food processing technology field.
Background technology
Cyanidin(e) is one type of water colo(u)r that extensively is present in the plant, belongs to flavonoids.The enhancing of Along with people's health care consciousness and the raising that food safety is required, the use of synthetic colour more and more is restricted, and the development of natural pigment obtains paying attention to day by day.That cyanidin(e) has is anti-oxidant, remove radical and certain physiology curative effect, and market outlook are very wide.Cyanidin(e) in the market is mainly from purple grape, black rice, black soya bean, strawberry etc.And purple corn is rich in cyanidin(e), and price is suitable, is the good source of extracting cyanidin(e).
Summary of the invention
The objective of the invention is to utilize purple corn to be raw material,, extract cyanidin(e) through the extractive technique of several kinds of different extraction agents; Different solvents possesses relative merits separately; Aqueous solution price is suitable, but extraction efficiency is limited, and the acquisition the finished product need consume significant amount of energy; Acidifying water increases than the water extraction rate, be prone to extraction because cyanidin(e) is stable under the peracid condition, but these acid can cause the part or all of hydrolysis of cyanidin(e) of acylations again when evaporation concentration, and possibly in product, form a large amount of salt, reduces product purity; Acidifying alcohol can improve the cyanidin(e) extraction yield greatly, and alcohol can be recovered further utilization, thereby has reduced extraction cost.
The present invention realizes with following technical scheme: a kind of extractive technique of purple corn anthocyanin; It is characterized in that: this extractive technique comprises that following several kinds of extracting solutions extract: (1) is extracting solution with water: solid-liquid ratio 1: 15; Extraction time 60rain extracts 37 ℃ of temperature, and extracted amount is 16.9mg/g; (2) with the sour water be extracting solution: solid-liquid ratio 1: 20, extraction time is 20min, and extracting temperature is 75 ℃, and extracted amount is 17.7mg/g; (3) with the acid alcohol be extracting solution: solid-liquid ratio 1: 20, time 60rain extracts 55 ℃ of temperature, and the cyanidin(e) extracted amount is 27.6mg/g.
Advantage of the present invention is: this process for extracting is to utilize purple corn to be raw material; Through the extractive technique of several kinds of different extraction agents, extract cyanidin(e), wherein acidifying alcohol can improve the cyanidin(e) extraction yield greatly; And alcohol can be recovered further utilization, thereby has reduced extraction cost.
Below in conjunction with embodiment the present invention is described further;
