Abstract
The invention discloses a method for killing microorganisms on surfaces of dry wolfberry fruits through circulating water vapor. The method is mainly characterized in that dry wolfberry fruits are put into a circulating water vapor sterilization cabinet, after water vapor is introduced, high-temperature short-time treatment is carried out, and dry wolfberry fruits are taken out and then placed in a clean room for cooling and packaging. According to the method for effectively killing microorganisms on surfaces of dry wolfberry fruits, the quality of dry wolfberry fruits is improved, any residue, wastewater and waste gas are not generated in the treatment process, no secondary pollution is realized, the sterilization time of circulating water vapor is short, the sterilization effect is complete, effective ingredients of the dry wolfberry fruits are not influenced and the method is simple and convenient, and easy to implement.
Description
Technical field
The invention belongs to food sterilizing technical field, the water vapour that espespecially circulates kills the method for dried fruit of lycium barbarum surface microorganism.
Background technology
Because part medlar fresh fruit does not add dust-proof, flyproof facility in natural drying process, fly during airing, insect fall, dust falls into and causes matrimony vine microbiological indicator to exceed standard; What have holds dried fruit of lycium barbarum with metal trough, and do not dress cleaners and polishes in selection, sales process, cause matrimony vine secondary pollution, sanitary index exceeds standard simultaneously.
The advantage of water vapour:
1 processing speed is fast: due to the specific heat of water vapour and ratio of heat transfer coefficient air large, the resistance to mass tranfer simultaneously in the dry medium of water vapour thousand can be ignored, and treatment cycle can obviously shorten;
2 securities are good: steam treatment avoids the danger of catching fire or exploding.Steam treatment exists without air, not oxidation and combustion reaction.Some can not, with the raw-food material of hot blast process, can use water vapour dry usually;
3 reduce the volume of equipment and the purge amount of waste gas: the specific heat of water vapour is large, and amount of steam is few, and this just can reduce the volume of equipment and the purge amount of waste gas;
4 are conducive to protection of the environment: steam treatment is carried out under air-proof condition, and dust content reduces greatly.
The temperature of steam treatment dried fruit of lycium barbarum is the boiling temperature of water under operating condition, when water vapour passes through dried fruit of lycium barbarum under circulation status, bacterium and other harmful microorganisms on dried fruit of lycium barbarum surface can be killed, the remains of pesticide on dried fruit of lycium barbarum surface can gasify by water vapour simultaneously, thus reduces matrimony vine residues of pesticides.
The sterilizing and the reduction agriculture that water vapour are used for dried fruit of lycium barbarum are residual, and safe noresidue, speed is fast, and cost is low, and Chinese-wolfberry nutritive material damage is few, is innovative point of the present invention.
Summary of the invention
Circulation water vapour is the object of the present invention is to provide to kill the method for dried fruit of lycium barbarum surface microorganism, it is under water vapour circulation status, high temperature, short time process is carried out to dried fruit of lycium barbarum, kill bacterium and other harmful microorganisms on dried fruit of lycium barbarum surface, thus improve dried fruit of lycium barbarum hygienic quality, do not produce any residue, waste water and waste gas in processing procedure, non-secondary pollution, adopt plant investment expense of the present invention few, operating cost is low.
To achieve these goals, technical solution of the present invention is: circulation water vapour kills the method for dried fruit of lycium barbarum surface microorganism, and it comprises the steps:
(1) dried fruit of lycium barbarum is laid in porcelain dish, surface coverage one deck gauze;
(2) be placed in circulation water vapour sterilizing cabinet after;
(3) pass into water vapour after, carry out high temperature, short time process;
(4) take out when the water vapour sterilizing cabinet pressure that circulates reduces to zero, put in toilet and cool, packaging.
Circulation water vapour of the present invention kills the method for dried fruit of lycium barbarum surface microorganism, and the thickness that in wherein said step (1), dried fruit of lycium barbarum is piled up is 1-5cm.
Circulation water vapour of the present invention kills the method for dried fruit of lycium barbarum surface microorganism, and in wherein said step (3), high temperature, short time process starts the temperature of timing is 100 DEG C to 110 DEG C.
Circulation water vapour of the present invention kills the method for dried fruit of lycium barbarum surface microorganism, and in wherein said step (3), high temperature, short time process starts the interior pressure of timing is 0.1-0.15Mpa.
Circulation water vapour of the present invention kills the method for dried fruit of lycium barbarum surface microorganism, and in wherein said step (3), the time of high temperature, short time process is 20-30 minute.
After adopting such scheme, the present invention, by pure physical method, by the process of water vapour high temperature, short time, kills the microorganism on dried fruit of lycium barbarum surface, thus improves dried fruit of lycium barbarum hygienic quality.Do not produce any residue, waste water and waste gas in processing procedure, non-secondary pollution, adopt plant investment expense of the present invention few, operating cost is low.
Circulation water vapour sterilization time is short, sterilization effect thorough, do not affect again the active ingredient of dried fruit of lycium barbarum, simple and easy to do.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth the present invention further.But these embodiments are only limitted to illustrate that the present invention and being not used in limits the scope of the invention.
Embodiment 1
The present invention's water vapour that circulates kills the embodiment of the method for dried fruit of lycium barbarum surface microorganism, the steps include:
Dried fruit of lycium barbarum is laid in porcelain dish, thickness 2 centimetres, surface coverage one deck gauze, puts in circulation water vapour sterilizing cabinet, pass into water vapour, when temperature rises to 100 DEG C to 110 DEG C, interior pressure is 0.1Mpa, timing 20 minutes, then takes out, puts in toilet and cool when pressure reduces to zero.The YXQ-WF2122 type rectangle steam sterilization cabinet that circulation water vapour sterilizing cabinet adopts Hengyang City He Chuanyao machine Science and Technology Ltd. to produce.
Dried fruit of lycium barbarum (during non-sterilizing):
Result: during non-sterilizing, it is 25 × 10 that every gram of dried fruit of lycium barbarum contains total plate count
4clump count (CFU).
The detection method of total plate count performs according to national standard " GB4789.2-2010 national food safety standard food microbiological examination total plate count mensuration ".
Dried fruit of lycium barbarum (after Ultraviolet radiation 24h):
Result: irradiate through ultraviolet 24h, it is 16200 clump counts (CFU) that every gram of dried fruit of lycium barbarum contains total plate count.
