Description
Technical field
The invention belongs to agricultural product and food processing technology field, relate to the sterilizing methods of the dehydration spinach that a kind of catalysis type infra-red radiation technology exceeds standard to bacteria containing amount.
Background technology
Dehydrated vegetables is one of leading products in China's agricultural exports, developed countries such as the state-owned Japan of main exit, the U.S., Korea S, European Union, can play the effect of providing additional supplies with prosperous, be food salable in the world, wherein spinach is one of staple of China's outlet dehydrated vegetables class, contains a large amount of vitamins and abundant mineral matter element, and cultivated area is wide, aboundresources can be used as a kind of good compensation process that eats leaf vegetables in some developed countries and fresh vegetables shortage area.Microbiological indicator is one of the index that spinach importer keeps under strict control of respectively dewatering.Because be difficult to killing microorganisms in the process of manufacture of dehydration spinach, the content of microorganisms situation of exceeding standard happens occasionally in outlet.And in case the suitable growth of microorganism of external environmental condition, the dehydration spinach will be taken place putrid and deteriorated, causes serious economic loss.
The dehydration spinach that exceeds standard for bacteria containing amount, the tradition sterilizing methods is to adopt earlier the high-temperature steam sterilization to be dried to safe moisture (8%) to reach the effect of sterilizing simultaneously and dewatering under 60 ℃～70 ℃ of temperature in 100 ℃～110 ℃ of the high temperature heated-air drying of sterilizing, and then utilize down dehydration spinach.Color and luster and the poor quality of this method secondary drying and dehydrating spinach, and energy consumption is bigger.In order to improve the quality of sterilization back dehydration spinach, generally adopt Co in recent years
60Irradiation method carries out sterilization treatment, but present Co
60The security of irradiation method also exists certain dispute, and the radiation agent is residual also certain harm.Currently used sterilization technology can not solve simultaneously well that dehydration spinach microorganism exceeds standard and the problem of poor product quality, at the development bottleneck of prior art, is badly in need of the method for seeking a solution.
Summary of the invention
The present invention provides catalysis type infra-red radiation and the follow-up insulated sterilizing method of a kind of spinach that dewaters in order to overcome above-mentioned the deficiencies in the prior art.
Catalysis type infra-red radiation and the follow-up insulated sterilizing method of dehydration spinach of the present invention, carry out according to following step:
(1) sterilized water of the dehydration spinach surface sprinkling constant weight that exceeds standard to bacteria containing amount leaves standstill 15min, transfers the water content quality to count 10%～30%;
(2) spinach that will dewater evenly is tiled in and is arranged in stainless steel mesh under the infrared emittance, open natural gas catalysis type infrared emittance, adopt the infra-red radiation method that the dehydration spinach is sterilized, spinach water content to be drained off reaches safe moisture and namely stops infra-red radiation
(3) the dehydration spinach after the infra-red radiation processing is transferred to continuation sterilization in the drier, 70～90 ℃ of holding temperatures, temperature retention time 10～60min rapidly;
(4) after sterilization finishes, obtain bacteria containing amount dehydration spinach product up to standard.
Step (2) 50～180s of described infra-red radiation time wherein.
Wherein the pressure of the described natural gas catalysis type of step (2) infrared emittance is 2kPa.
Wherein the described dehydration of step (2) spinach surface temperature is 100 ℃.
The resulting dehydration of the present invention spinach product, all within acceptability limit, the logarithm value of the residual motility rate of total number of bacteria is-2.09 ± 0.09～-1.83 ± 0.05 for total plate count and coliform; Appearance color is compared total color difference E value with fresh spinach be 1.43 ± 0.15～7.63 ± 0.44, whiteness L* value is 42.86 ± 0.47～52.94 ± 0.14, redness degree a* value is-11.20 ± 0.04～-6.59 ± 0.19, and yellow chromaticity b* value is 26.93 ± 0.66～29.34 ± 0.41; The chlorophyll retention rate is 77.4%～98.9%.
Advantage of the present invention: compare with existing sterilization technology, the infra-red radiation sterilization technology has that penetration power is strong, processing time weak point, no chemical residual, product quality advantages of higher, can be applicable to food and processing of farm products field, and industrialized popularization value is higher.Consideration for food security, glass and the use of ceramic infrared emittance in food and processing of farm products are very limited, and the catalysis type infrared emittance is to be radiant energy by catalyst with conversion of natural gas, and it is higher to have an energy transformation ratio, more energy-conservation, the more high advantage of security.Catalysis type infra-red radiation technology and generator are still blank in China at present.Catalysis type infra-red radiation technology can cause death to microorganism and damage to a certain degree, and follow-up insulation is handled also can further ensure the microorganism of killing in the dehydration spinach.The present invention makes the microbiological indicator of dehydration spinach up to standard except killing microorganisms effectively, the product quality of the spinach that can also guarantee preferably to dewater.
