It is reported have a lot of country to be eaten as staple food grain by potato in the world, European Countries potato per capita year consumption figure be stabilized in 50-60kg, and Russia per capita potato consumption figure reach 170kg especially.At present, China only has minority area to be eaten as staple food grain by potato, is more eaten as dish by potato.In order to comply with world's Development of Potato Industry trend, for common people provide nutrient health staple food products more, China proposes the plan of potato the industrialization of staple food from national strategy height, Potato ring rot bacteria is become the staple food products such as bread, steamed bun, noodles adapting to Chinese's consumption habit.Potato staple food strategy has not only enriched staple food products kind, also can effectively adjust crop mix, realize agricultural resource efficiency utilization.
Zheganmian is the characteristic snack in Wuhan, Hubei, is referred to as Chinese five your name faces with mix sauce face, Henan stewed noodles, Shanxi plande noodles and Sichuan Sichuan noodles of Pekinese.The noodles of zheganmian are very thin, but have biceps, and color and luster is yellow and glossy, and flavour is delicious, mixes with the colors such as sesame oil, sesame paste batching time edible, looks good, smell good and taste good.At present, on market large-scale industrial production zheganmian mainly dewater after convenience type zheganmian, dewatering type comprises heated-air drying and fried dehydration etc., based on fried dehydration product, and fast food fresh flour wetted surface industrialization industry lack.In Wuhan City, the fresh flour in all kinds of breakfast shop or fresh-cut face produce primarily of workshop or small business, shelf-life is short, safe and sanitary can not get ensureing, develop long shelf-life thus, can be mass-produced fast food fresh flour wetted surface product, greatly can meet consumer for this type of product demand, promotes zheganmian industry development.
Lotus rhizome, water chestnut and lotus seeds all belong to aquatic vegetable product, except being rich in starch, have various health care functions.Research shows that lotus root starch has the antidiarrheal that helps digestion, appetizing heat-clearing, nourishing are nourished one's nature, the effect of the pachylosis that enhances metabolism, prevents; Water chestnut starch has the effect such as anticancer antibacterial, sharp intestines defaecation, diuresis row pouring, clearing lung and eliminating phlegm; Lotus nut starch has cancer-resisting, hypotensive, cardiac stimulant is calmed the nerves, nourish the effects such as qi-restoratives.Kudzuvine root starch is a kind of starch based health food deeply liked by consumer, has greasy clearly antipyretic, expelling phlegm and arresting coughing, hypoglycemic, protection cardiovascular health, adjustment endocrine effect.
Summary of the invention
The object of the present invention is to provide potato zheganmian product of the fresh wetted surface form of a kind of fast food and preparation method thereof, described potato zheganmian with the fresh wetted surface of fast food for product form, it is raw material with fresh potato that the present invention initiates direct, do not need to add any moisture and face, abandoned in traditional handicraft and utilize potato full-powder to prepare the method for zheganmian for raw material, economization prepares the loaded down with trivial details operation of full powder and energy consumption by fresh potato; By ultra high pressure treatment technology, reconstructization is occurred to the microstructure of farina, potato protein and potato dietary fiber in potato slurries, the potato slurries after processing are made to have possessed better physicochemical characteristic, the zheganmian prepared thus is relative to the zheganmian obtained without ultra high pressure treatment, there is better quality, comprise hardness, elasticity, gumminess, restoring force and chewability, and ultra high pressure treatment also gives zheganmian its more health-care efficacy; In addition, also with the addition of the nutritive plant powder be made up according to necessarily filling a prescription of lotus root starch, water chestnut starch, kudzuvine root starch and lotus nut starch especially to give potato zheganmian better nutrition and health care effect, this instant fresh wetted surface is under 0-4 DEG C of low temperature, shelf-life is longer, can meet market and consumer's diversified demand.
