Abstract
The invention provides a method for inhibiting enzyme and killing bacteria. The method is characterized as follows: materials are put in a closed container and the container is vacuumized (vacuum drying is carried out by microwave); the vacuumizing is stopped and inert gas is pumped; the container is heated by microwave; the heating by microwave is stopped and vacuumizing is carried out to achieve rapid cooling. The invention makes the most of the characteristics of speediness, uniformity and easy-control of microwave heating, protection of the inert gas and vacuumizing to achieve rapid cooling, thus achieving good effect of inhibiting enzyme and killing bacteria.
Description
Technical field
The present invention relates to a kind of method of inhibiting enzyme and sterilizing, concrete be meant a kind of microwave heating, inert gas shielding and evacuation combine method of inhibiting enzyme and sterilizing of cooling fast that adopts.
Technical background
At present the method for inhibitory enzyme activity mainly contains: add the thermally inactivating enzyme activity, drive oxygen, the metal ion of chelating enzymatic catalysis, transfer pH, add activity inhibitor in (sulfur dioxide, sulphite, inorganic salt, ascorbic acid etc.); Method for disinfection mainly contains: uviol lamp, steam, high pressure, cobalt 60, ozone, fill nitrogen, freshen antiseptic etc.
All there is one or several defective in said method at aspects such as heat time heating time, cost, safety, effects.
Summary of the invention
For overcoming above-mentioned defective, technical scheme of the present invention provides a kind of method of inhibiting enzyme and sterilizing.
The present invention has made full use of the microwave heating even fast easily protective effect and the quick refrigerative characteristics of evacuation of control, noble gas.
Concrete operations step of the present invention is as follows:
(1) material places the hermetic container evacuation
(2) (microwave vacuum drying)
(3) stop to feed noble gas in the evacuation hermetic container
(4) microwave heating
(5) insulation
(6) stopping the microwave heating evacuation cools off fast
Compare with existing inhibiting enzyme and sterilizing technology, technical scheme provided by the invention has following advantage:
1. adopt microwave heating, have the characteristics quick, even, that easily control that heat up.
2. inert gas shielding heats up down, can prevent the generation of the non-enzymatic browning that enzymatic browning and aerobic participate in, and plays good color fixative effect.
3. the mode that adopts evacuation has the characteristics rapidly of lowering the temperature to material cooled.
4. the entire process process is not added any composition.
Conclude above advantage as can be seen the present invention have safe and reliablely, inhibiting enzyme and sterilizing is thorough, the characteristics that color fixative is respond well.
The specific embodiment
Embodiment 1

(5) stop microwave heating, adopt water cycle vacuum pump evacuation to cool off fast.
Embodiment 4
(1) gets Lentinus Edodes fine powder 200g, place hermetic container to adopt water cycle vacuum pump evacuation;
(2) stop evacuation after, feeding pressure in the hermetic container is 1 atmospheric carbon dioxide;
(3) adopting power is the microwave heating 2min of 500W;
(4) the controlled microwave heating power is 100W, insulation 30s;
(5) stop microwave heating, adopt water cycle vacuum pump evacuation to cool off fast.
Key point of the present invention is that material to be processed rapid evacuation behind employing microwave heating under the protection of noble gas cools off fast.
Claims (5)
- The method of 1 one kinds of inhibiting enzyme and sterilizings, concrete steps are as follows:1.1 material places the hermetic container evacuation;(1.2 microwave vacuum drying);1.3 stop to feed noble gas in the evacuation hermetic container;1.4 microwave heating;1.5 insulation;1.6 stopping the microwave heating evacuation cools off fast.
- The method of 2 a kind of inhibiting enzyme and sterilizings according to claim 1, it is characterized in that: hermetic container is the hermetic container of vacuum-pumping in the operation 1.1, make by the material that does not absorb or seldom absorb microwave energy basically, as: politef, polypropylene, polyethylene, polysulfones etc., plastic and glass, pottery etc.
