Description

A kind of processing method of instant sweet corn
Technical field
The invention belongs to ready-to-eat food manufacture field, be specifically related to a kind of processing method of instant sweet corn.
Background technology
Corn is a mutation of corn, and it is a kind of emerging economies crop of fruits and vegetables dual-purpose, and along with the raising of people's living standard, this high-grade nutrient food of corn is valued by the people gradually.In least easy contaminated vegetables and fruits list, corn accounts for former positions, few more a lot of than residues of pesticides such as common leaf vegetables, cucumber, tomatoes.In west, it has become a kind of popular vegetables.Consuming maximum country is the U.S. and Japan, and producing at present upper common corn has common corn and super-sweet corn.The nutritional labeling of corn is much higher than conventional corn, and sugary 20% left and right exceedes 1 times of watermelon, is 5~6 times of conventional corn, contains abundant VB simultaneously; , VB., VC, VA and amino acid, maltose, fructose, melitose etc., nutritive value is very high, and easily digested, often edible corn can promote raising and the body development of children's intelligence to impel the elderly to promote longevity.Vertical fragrant, sweet, crisp, tender, soft, unique flavor, highly palatable, can be used as fruit edible, also can stir-fry and eat and cook soup, and can be processed into the tinned food of pasty state or whole grain, in very great demand on market at home and abroad, Hongkong and Macro citizen are referred to as " health fruit corn ".
Corn Seasonal Harvest is strong, and after gathering, quality deterioration is very fast, and shelf life is short, and the fresh-keeping difficulty of fresh fringe is large, if deal with improperly easily aging and lose its fresh quality and local flavor.Corn after receipts also processing is in time processed or is edible as early as possible, otherwise sugariness will decline very soon, and local flavor is very fast bad change also.Corn after generally gathering at normal temperatures quality only can keep 1~2 day.Due to the particularity in corn quality, the difficulty of processing and antistaling is very large.Separately or be combined with after existing fresh-keeping measure or means, the freshness date of corn also can only extend to about 15 days.Therefore, worldwide, corn, except having that minute quantity is fresh and selling, is sold after being mostly processed into seed can or quick-frozen, and the processed goods of other corns is little.
Prior art discloses the production method of the instant sweet corn that a kind of multistage sterilization can normal temperature preserves, Granted publication number is CN102405966B, has mainly solved the problem that multistage sterilization can normal temperature be preserved instant sweet corn.
But the tender anti-aging of the guarantor of instant sweet corn aspect, or existence much has problem to be solved.
Summary of the invention
The object of the present invention is to provide a kind of processing method of instant sweet corn, well solve instant sweet corn and protected tender age inhibiting problem, nutritious, tasty, long fresh-keeping period, method simple practical of the present invention, be convenient to promote, have good economic benefit.
The concrete technical scheme that realizes the object of the invention is: a kind of processing method of instant sweet corn, concrete steps comprise shell, select, segment, cleaning, pack and vacuum-pumping and sealing, soaking type high pressure sterilization, cooling, wipe bag step, unlike the prior art: further comprising the steps of, the sweet corn of cleaning is weighed, separate two kinds of specifications of single, double corn ear, then two kinds of specifications enter deairing step simultaneously.
Good exhaust corn ear is immersed in salt solution cooling.
The central temperature 80-85 DEG C of described steps of exhausting.
Described soaking step be in 1.5% salt solution 10 seconds carry out cooling.
In described segment step, be that corn ear is excised to two ends, every excellent length list rod is controlled at 15-18cm, double stick 14-16cm.
Described vacuum-pumping and sealing step, sealing vacuum control-0.085Map, the time of single rod is 5-6 second.
Described vacuum-pumping and sealing step, sealing vacuum control-0.085Map, double stick time 8-9 second, heat sealed time 2.0 seconds.
It is 121 DEG C that described sterilisation step adopts temperature by high temperature sterilization technique, and sterilizing time is 25 minutes.
In described cooling step, be that the corn ear of sterilization is carried out cooling 30 minutes, cooling water chlorine residue 0.5-0.8PPm..
The invention has the advantages that:
By steps of exhausting and soaking step in 1.5% salt solution 10 seconds carry out cooling, can get rid of the air in corn fruit ear body, the degree of oxidation of corresponding minimizing raw material, be conducive to preserve color and luster and the nutrition of product, in salt solution soak carry out cooling benefit be have no side effect can also protect tender anti-aging and protect look.
Production method of the present invention, have no side effect, can well protect tender anti-aging to instant sweet corn, color-protection technique process and equipment are simpler, cost of investment is low, be a kind of simple, economic benefit and all more significant instant corn ear production methods of social benefit, it is unchanged that the shelf-life can reach in 1 year color and taste.
