Description
Technical field
The present invention relates to food processing technology field more particularly to a kind of pollen pini method for disinfection.
Background technique
Pollen pini (Pine pollen) is the unisexual flower of pine genus plant, refers to masson pine, Chinese pine, Japanese red pine and pinus yunnanensis etc.
The spermatid for belonging to several plants is the pollen kind of China's tradition food medicine dual-purpose, there is QI invigorating to remove wind, astringing to arrest bleeding, beauty treatment
Lengthen one's life and other effects.In addition, pollen pini is rich in more than 200 kinds of protein, free amino acid, polysaccharide, fatty acid, flavones, enzyme, sterol etc.
Bioactive substance, also referred to as " pine is yellow " and " natural miniature nutrition library ".In order to improve the biology benefit of pollen pini nutritional ingredient
With rate, after pollen pini sterilization treatment, broken wall treatment need to be carried out.However after broken wall in pollen pini lipid easily with lipase, air etc.
It contacts and hydrolysis even oxidation reaction occurs, cause rancid and form bad smell, to reduce the sense organ of pollen pini even
Nutritive value.Therefore it needs to seek a kind of sterilization method that can be sterilized and be passivated lipase or even lipoxygenase.
Irradiation is one of efficient cold sterilization technology, effective significant, the features such as having a wide range of application and is environmentally protective.In height
Energy electron beam is a kind of non-thermal technology technology, passes through the mechanical masterpiece such as high speed shear, the higher-order of oscillation, cavitation and convection current shock
With with corresponding fuel factor, physics, chemistry and the structural property that can induce material macromolecular change, and are finally reached homogeneous simultaneously
Have the function that the blunt enzyme of sterilization simultaneously.Together60Co irradiation sterilization is compared, and the great advantage of electron-beam accelerator irradiation is electron beam
Orientation is concentrated, using energy source is abundant, and irradiation efficiency is high and dosage is evenly distributed, and will not generate radioactive waste.In addition, high cobalt
Source and useless source processing cost highlight the economic advantages of electron beam sterilization more.Infrared Radiation Technology not only can be killed effectively
Pathogenic bacteria in food, and can preferably keep the original quality of food and inactivate lipase effect it is preferable, principle
When being that the frequency of object molecular thermalmotion is consistent with the frequency of infra-red radiation, infra-red radiation is converted into point by molecule absorption quickly
The warm-up movement of son, aggravates molecular motion, temperature of charge increases.
Summary of the invention
The present invention irradiates the problem to pollen pini sterilizing expense high effect difference for existing cobalt source, provides a kind of pollen pini and kills
Bacterium method.
The technical scheme to solve the above technical problems is that a kind of pollen pini method for disinfection, which is characterized in that packet
Include following steps:
1) pollen pini of the non-broken wall of fresh mature, the filtering of 80 mesh, room temperature shady place ventilation 12h are chosen；
2) pollen pini obtained by step 1) is subjected to electron beam sterilization, sterilising conditions are as follows: it is 5- that electron beam, which exports energy,
10MeV, electron-beam scanner and pollen pini distance are 520mm, scan frequency 400-450pps, sweep length 8.6A；
3) pollen pini after step 2) electron beam sterilization is moved on in the pallet of infrared laminar baking oven, opens infrared function,
It is sterilized after 10-20min at 90-110 DEG C, closes infrared function, 20min will be kept the temperature after near 60 DEG C of temperature；
4) pollen pini obtained by step 3) is cooled to room temperature, measures its total plate count, mould and yeast, coliform, cause
Germ and lipase active five indices；
5) it is fitted into sterile bag, is protected from light preservation at room temperature.
Wherein, the pollen pini be Pollen of Masson Pine, Chinese pine pollen, Mount Huang pollen pini, Pollen of Yunnan Pine, korean pine pollen,
The mixing of one or more of Huashan pollen pini, kahikatea pollen.
Step 4) measures five indices are as follows: total plate count≤2000cfu/g, mould and yeast≤100cfu/g, coliform
Group≤5MPN/100g, no pathogenic bacteria, lipase active≤5U/g
The beneficial effects of the present invention are: method for disinfection of the present invention uses higher electron beam radiant energy, combine heat auxiliary
Far infrared inactivates lipase while can effectively reduce the indigneous flora in pollen pini, improves the storage of preserved egg powder raw material
Stability is hidden, pollen pini obtained can preferably keep nutritional quality and organoleptic attribute, and coloration and crude fat content do not have
Significant changes.
