Abstract
The invention discloses a freshness-preserving processing method of tender corns and relates to the technology of food processing. The method is characterized by comprising the following steps of: peeling, selection, cutting, cleaning, packaging in vacuum and sterilization at a high temperature. The manufacturing process is simple; the original flavor of the corns can be kept; the nutrient substances and sugar of the corns are not lost; the corns prepared by the method can be stored for 16 months at normal temperature, so the storage period of the corns is greatly prolonged; and the corns can be commercially produced on a large scale and has high economical benefit.
Description
Technical field
The present invention relates to foods processing technique, the processing method for keeping fresh of concrete a kind of green corn.
Background technology
Green corn is with delicious flavour, nutritious the liking of urban and rural residents that be subjected to deeply.But, the popularization of fresh edible maize and the commercialization production of green corn are restricted because the processing and antistaling problem of green corn is not resolved.This mainly is because the processing and antistaling process of green corn runs into two problems: at first be that green corn preserves difficulty, particularly waxy corn and corn, after gathering under field conditions (factors) its sugar part can only preserve 10-20 hour.The method of employing quick-frozen is the cost height not only, and also is difficult to stop the conversion of primverose part in sales process.Next is that maize fragrance is difficult to preserve, and traditional canning method is often destroyed the color, smell and taste of corn, makes its characteristics that lose green corn, and carries inconvenience, so be difficult to promote on producing.At present, the resident is to eat after buying the steaming or boiling tender corn of gathering the same day from the market to the eating method of green corn basically.This method both had been subjected to the restriction in season, can not form industrialization, commercialization production again.If adopt scientific methods to stop the conversion of primverose part and the disappearance of maize fragrance, prolong storage period, not only the edible demand of resident can be satisfied throughout the year, and the value of corn can be improved greatly green corn, obtain good economic benefit.
Summary of the invention
The present invention needs the technical solution problem to provide a kind of processing method for keeping fresh that can keep maize fragrance and the green corn of prolongation corn holding time.
The processing method for keeping fresh of a kind of green corn is characterized in that: may further comprise the steps,
1, will gather good green corn peeling and remove palpus;
2, the corn after the peeling is carried out selected, select no mildew, sick worm, the good-looking corn of profile;
3, corn root after selected and head are sheared, be divided into 14-16cm, 16-18cm, three classifications of 18-20cm according to its size;
4, will shear sorted corn and put into basket, and again basket will be placed in the service sink and it be washed 5-15 minute with clear water;
5, it is carried out vacuum packaging after will washing good corn control water;
6, the corn that vacuum packet is installed is placed on the stainless steel frame, push sterilization tank and carry out high-temperature sterilization, elder generation uses 110-130 ℃ high-temperature sterilization 10-30 minute, again the hot water in the sterilization tank is bled off, put into cold water, make the temperature in the sterilization tank remain on 20-30 ℃, corn is kept releasing after 10-20 minute get final product.
Beneficial effect of the present invention: manufacture craft of the present invention is simple, the genuineness that can keep corn, guarantee that its nutritive value and sugar part can not run off, can preserve 16 months at normal temperatures through the corn that the present invention produces, prolonged the pot-life of corn greatly, and can be in enormous quantities, commercialization production, the economic benefit height.

Fig. 1 is a process chart of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with specific embodiment, further set forth the present invention.
As described in Figure 1,1, the processing method for keeping fresh of a kind of green corn, may further comprise the steps,
A. will gather good green corn peeling and remove palpus;
B. the corn after the peeling is carried out selectedly, select no mildew, sick worm, the good-looking corn of profile;
C. corn root after selected and head are sheared, be divided into 14-16cm, 16-18cm, three classifications of 18-20cm according to its size;
D. will shear sorted corn and put into basket, and again basket will be placed in the service sink and it be washed 10 minutes with clear water;
E. after will washing good corn control water it is carried out vacuum packaging;
F. the corn that vacuum packet is installed is placed on the stainless steel frame, pushes sterilization tank and carries out high-temperature sterilization, earlier with 121 ℃ high-temperature sterilization 20 minutes, again the hot water in the sterilization tank is bled off, put into cold water, make the temperature in the sterilization tank remain on 25 ℃, corn is kept releasing after 15 minutes get final product.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
