Description
Technical field
The present invention relates to corn deep processing technology field, the sweet corn can processing technology of specifically a kind of second level sterilization.
Background technique
Corn is annual monoecism cross-pollinatd plant, and plant is tall and big, and stem is strong, is important cereal crops and feeding
Material crop and the highest crops of whole world total output, cultivated area and total output are only second to rice and wheat.Corn one
Directly all it is known as life prolonging food, protein rich in, fat, vitamin, microelement, cellulose etc. have exploitation high
Nutrition, high biological function food great potential.But since its heredity is complex, variation type is abundant, in routine
In breeding process there is excessive cycle, the coefficient of variation is excessive, influences the shortcomings that offspring development, and modern biotechnology breeding skill
Art not only overcomes disadvantages mentioned above and deficiency, while also improving breeding speed and quality.
Corn is one of most important grain in the world, and there are about one third populations using corn as main for world today
Grain, wherein corn accounts for 50%, Duo Zheda 90% so that Africa accounts for 25%, and Latin America accounts for 40% in Asian food composition.
The protein content of corn is higher than rice, and fat content is higher than flour, rice and millet, and heat content is higher than flour, rice and height
Fine strain of millet, but the disadvantage is that particle is big, poor eating, sticky school in the lower area of living standard, corn is important grain.City and compared with
Developed regions, corn are the adjustment indispensable food of taste.With the development of Processing Industry of Con Grain, the edible quality of corn is not
Disconnected to improve, new corn food such as cornflakes, maize flour, maize pulp, special corn flour, fast food corn etc. generates therewith, and can
Noodles, bread, biscuit etc. is further made.Corn also can be processed into as zein, corn oil, monosodium glutamate, soy sauce, white wine etc.,
These products are at home and abroad popular in the market.
Corn is the favorite canned vegetables of American-European countries, has two kinds of yellow and white according to color, yellow accounts for about yield
95% or more.There are whole grain, paste by form point, wherein whole grain accounts for 70% of total output or so.Europe is with import whole grain product
Main, Asia, North America and the Middle East are based on import paste.Whole world sweet corn can annual output is ten thousand tons about more than 100, wherein with beauty
State's yield is maximum, accounts for 3/4, exports more than 10 ten thousand tons, other corns produce state-owned Canada, France etc..Sweet corn can
The state-owned Japan of main body entrance, Germany, Philippine and the portioned product by Hong Kong transit, in recent years, sweet corn can into
Mouth amount constantly rises.Show sweet tea jade light can main exit Japan, the Germany, Philippine, perfume (or spice) in the U.S. according to other statistics
The ground such as port.Sweet corn can competition in the international market is violent, and the U.S. has nearly 100 years processing histories, and also there is nearly 30 year calendar in Japan
History, China start late, and annual export volume is less than 3000t at present, but China is vast in territory, can plant from south to north.Corn
The quality of can depends on raw material variety and processing technology is equipped, and China should be in raw material breeding and processing technology, equipment from now on
It further explores, to accumulate experience.Sweet corn can quality is high to maturity requirement, and raw material site should be established attached in factory
Closely, development in flakes.Simultaneous processing also answers active adoption mechanization tinuous production to carry out.There are many sweet corn can form, mainly
There are whole grain and paste.Whole grain can technique includes decladding, palpus, inspection, cutting, tinning is gone to add saline solution, sealing, sterilization, cooling.Paste
The technique of shape sweet corn can includes cutting, cleaning, mixing, tinning, sealing, sterilization and cooling.
Ohmic sterilization is that the low frequency ac of 50~60Hz is directly led people's food material using electrode, carries out ohm and adds
Heat, because food dielectric property itself makes food product generate heat, to reach sterilization purpose.It can using Ohmic heating sterilization
The rate of heat addition (about 1~2 DEG C/s) more faster than conventional method is obtained, shortens heating sterilizing time, obtains high-quality product.It is killing
During bacterium, food sterilization temperature with material electrical properties in addition to having outside the Pass, also with the density of material, specific heat capacity and thermal conductivity etc.
Thermal property is related.
Although Ohmic sterilization is a kind of efficient sterilization mode, but since it is more demanding for the tightness of environment,
Therefore it is unable to get and is widely applied, simplified Ohmic sterilization process is added in consideration in the front end process of cooking disinfection, is protecting
Yields is improved while demonstrate,proving processing efficiency.
Summary of the invention
