Managing has synergistic function to the microorganism in killing material and trophosome, i.e. the controllable instantaneous pressure of impulse magnetic field collaboration pulsation
The bactericidal effect of difference processing collaboration processing is better than individually successively handling using the impulse magnetic field of equivalent parameters condition, then using same
Deng the bactericidal effect sum of the controllable instantaneous differential pressure processing of pulsation of Parameter Conditions.After material is handled through present invention process, sample warp
Detected after culture without microbe colony.
(4) preparation-obtained carrots chips products taste of the invention is more crisp, and deformation ratio is low.By controllable instantaneous pressure
Difference processing is used with solar association vacuum heat pump, can produce cooperative effect.On the one hand, high temperature vapours is passed through, temperature is hypertonic
It is thoroughly fast, the heating of material moment is gone out enzyme, pressure leak process pressure differential is huge, carrot structure is disintegrated loose；On the other hand, vacuum
The contraction of carrot slice structure in the drying process can effectively be prevented by drying.It is final cause carrot slice prepared by present invention process compared with
Conventional convection dry products quality is significantly increased.Aid in solar association vacuum heat pump dried by controllable instantaneous differential pressure
Product, can form porous microstructure, that is, produce tasty crispy texture.
(5) the full powder nutrition of preparation-obtained carrots chips and carrot nutritional of the invention retains more complete, and class is recklessly
Radish element retention rate is significantly improved.Without any food additives in the present invention, the Color Quality of raw material can be effectively maintained.
Controllable instantaneous differential pressure processing can disintegrate carrot tissue structure, or even chromoplast in carrot cell can be promoted to discharge carotenoids
Element.Carrots chips crispy in taste, consumer's identical during intake, which chews mode, can make crisp chip broken more completely
The bioavilability of Carotenoid from Carrot can further be improved.It is gentle using solar association vacuum heat pump drying condition,
Advantageously in the reservation of nutriment.
(6) production equipment that the present invention is used is ripe, technique is simple, can use operating in a key..
