Description

A kind of preservation method of fresh-cut rhizome vegetable
Technical field
The present invention relates to food processing technology field, particularly a kind of preservation method of fresh-cut rhizome vegetable.
Background technology
Fragrant taro (Eolocasia esculenta) belongs to Araeceae taro and belongs to, and being perennial unifacial leaf perennial root herbaceous plant, is one of important tuber crops in the tropical Asian-Pacific area.Fragrant taro, in the regional extensive cultivation of south China, southwest and Southeastern China, because of planting type and regional climate etc., defines local special product in zones of different, the fragrant taro in the Lipu as Guilin, the Zhang Xixiang taro in Shaoguan, Guangdong, the yam betel of Southern Hunan.The fragrant taro of high-density planting is mostly about 0.75 ~ 2.0 kilogram, and the fragrant taro of low-density cultivation mostly is about 2.0 ~ 5.0 kilograms, and a large person reaches more than 6 kilograms.
During current fragrant taro fresh goods is sold, in general, fragrant taro individuality is larger, and price is higher; Another main aspect, fragrant taro is sold in units of individuality, for most of family, the fragrant taro that single purchase is one 3-4 kilogram, once edible about 500 grams, fragrant taro storage will take the more space of refrigerator, if be placed in-20 DEG C frozen, the local flavor of perfume taro can not show a candle to fresh goods, and continuous eating feels not comply with one's wishes, and a large fragrant taro brings inconvenience and " waste " to consumer really, therefore, the plant husbandry of fragrant taro in the urgent need to being realized cold chain supply supermarket by fresh-cut, thus meets more consumer demands, and then improves the economic benefit of fragrant taro plant husbandry.
Fragrant taro will produce a series of physiological acoustic signals after cutting, these changes on the freshness of fragrant taro, quality even nutritional labeling will make a significant impact, what especially enzymatic browning and microbial spoilage caused is rotten, and this is also one of key factor affecting the fresh-cut fragrant taro shelf life life-span.
Enzymatic browning slows down brown stain process by the Chemical Control of anti-browning agent, and conventional anti-browning agent comprises the process such as citric acid, tartaric acid, ascorbic acid, sulphite, three pears hydrochlorates, Sodium Benzoate; In conventional chemical anti-browning agent, the health of Long-Time Service to human body such as aldehydes matter causes that the sense of taste of fresh-cut fruit and vegetable changes, sulphite and benzoate are unfavorable; Fresh-cut fruit and vegetable causes histiocytic under oxygen atmosphere because of otch damage, also easily produces cellular oxidation injury, causes the shelf life lost of life of fruits and vegetables.
The fresh-keeping report having some preliminary of the domestic fresh-cut to fresh taro at present, as, after Xu Xiaochuns etc. (2006) observe Zhang Xixiang taro peeling stripping and slicing, through sulphur blanching vacuum packaging process [with sodium sulfite (0.3%), alum (0.2%), 2min is soaked in the colour protecting liquid that vitamin C (0.2%) is mixed with, pull out and drop into blanching 30s in 100 DEG C of boiling water immediately], maintain local flavor and the soluble solid content of the fragrant taro of fresh-cut preferably, total phenol content and polyphenol oxidase, peroxidase activity is lower, vacuum packaging K cryogenic treatment is conducive to the fragrant taro fresh-retaining preserving of fresh-cut, but the program is only for physiology and the quality comparison of the fragrant taro of the processing process of laboratory test, Hu Weirong etc. (2010) are with the fragrant taro in Hunan for examination material, and research variable concentrations ascorbic acid and shitosan process are on the fragrant storage effect of taro of fresh-cut and the impact of physiological acoustic signals.Result shows, under 15 DEG C of reserve temperatures, compared with the control, ascorbic acid (VC) coordinates the outward appearance and nutrition that process and maintain the fragrant taro of fresh-cut preferably with shitosan, reduce weight-loss ratio and the brown stain degree of the fragrant taro of fresh-cut, and suppress polyphenol oxidase (PPO), peroxidase (POD) and diastatic activity.Xu Xiaochuns etc. (2007) are reported, under 4 DEG C of reserve temperatures, vacuum packaging energy (VP) is applicable to the short-term cryopreservation of fresh-cut taro, and igelite (PVC) blister-pack is applicable to the longer-term storage of fresh-cut taro.These researchs not yet can form practical technique, and fragrant taro is as a kind of agricultural product of top grade, its speciality as organic food and safety food must be guaranteed, the sulfide of food security hidden danger risk can not be used (as sulphite etc., need avoid using), and according to the characteristic of its Postharvest physiological changes, physiology should be implemented and decay and reach fresh-keeping effect, extend its shelf life.
