Description
Technical field
A food impregnation processability method for the strong electrolyte gas current that function signal is controlled, the present invention relates to a kind of novel foodstuff impregnation processability method, is applicable to the maceration extract of strong electrolyte class, belongs to and uses electromagnetic food processing technology field.The present invention compares with vacuum impregnation technology, can within the shorter time, complete the impregnation process to raw-food material.Can complete the reinforcement of wet method salt marsh, painted processing and trace mineral element.
Background technology
The traditional infusion of food processing method of China comprises five large classes, i.e. salt marsh, marinate, cured with germented grains, saucing and sugaring.Infusion of food is of a great variety, and the product being wherein widely known by the people has all kinds of pickles, pickles, acid bubble ginger splices, seasoning sunflower seed, salted eggs, Chicken Feet with Pickled Peppers and pigskin, wine preserved crab etc., and they are all subject to people's favor.The object of impregnation process is if hydrogen, sodium, potassium, calcium, iron, selenium, chlorion and sucrose, the little molecule infiltration of alcohols are in food tissue space and cell by all kinds of solute ions in dipping solution and molecule, because permeable pressure head is removed the part moisture in food, produce good local flavor simultaneously.In this process, in maceration extract solute diffusion rate be subject to that the partial pressure of the inside and outside various materials of histocyte is poor, the impact of dipping temperature, environmental pressure and raw-food material voidage.The aquatic products of brine cure particularly in infusion of food, because solute diffusion rate is slow, steeping can cause rotten, so general how pickled in the cold storage environment of 5 ℃, inevitably because of the long loss that causes soluble protein, vitamin, mineral matter and pigment of time.For accelerating the impregnation process of food, conventionally only have by improving dipping temperature, improve solute concentration and changing environment atmospheric pressure and undertaken.But because high temperature can cause the fermentation of infusion of food and become sour, therefore improve the mode that temperature is accelerated impregnation process, industrial, rarely has employing.Improve maceration extract solute concentration and can form " high salt " product, and must increase later stage desalinating process operation.Technology ripe application and that can accelerate food impregnation process only has vacuum impregnation technology (Vacuum Impregnation is called for short VI) at present, and central principle is to utilize hydrodynamics mechanism and the relaxation of deformation phenomenon that pressure reduction causes to improve pickled efficiency.In food tissue cell, have hole, under vacuum, at the inner low pressure bubble that forms of material, also cause iuntercellular apart from increase and mass expanded, under cell inside and outside differential pressure and capillary effect, outside liquid more easily infiltrates simultaneously.Conventionally in tens of minutes, complete the impregnation process of food, flood required several days with normal pressure or tens day time was compared greatly and shortened process time, therefore can extensive use.
The conductor of electric current is divided into two large classes, and the first kind is metallic conductor, and current forms is electronic current, and Equations of The Second Kind is electrolyte solution or fused electrolyte.Electrolyte can be divided into strong electrolyte and weak electrolyte, and strong electrolyte can ionize completely in solution, mostly is ionic compound and most of salt, and weak electrolyte ionization not exclusively, mostly is covalent compound.The conductive capability of electrolyte solution and degree of ionization, concentration, temperature have correlation, and current forms is gas current.In electrolyte solution, owing to containing a large amount of band negative ions, in having the environment of electrical potential difference, directional migration be can there is, according to the technology application of this principle, electrolysis, plating, electrophoresis and electrodialysis comprised.They are all to cause ion displacement by produce electrical potential difference between electrode, and wherein electrolysis, plating, electrodialytic processing object mostly are the negative ions in electrolyte, and its molecular weight is little; Electrophoresis is processed with the protein macromolecule class of a large amount of positron-electrons for some surfaces in solution.
Induction gas current introduces the magnetic flux changing in being full of electrolytical helical pipeline makes its production induced electromotive force drive the ionic transfer in solution loop system as " driving source ".In solution loop system, according to the different induced electromotive forces with different rules of the variation rate of magnetic flux of its coil, produce, and then there is different driving effects.This is because according to the motion of charged ion in electric field, and the power (F) that promotes charged ion motion equals ion institute with the product of net charge amount (Q) and electric-field intensity (X), i.e. F=QX.Because flux change rate is different, the alternation induced electromotive force producing is different at the peak value of positive negative direction, and the electric field force size that ion is subject at different directions is different with the duration.And the reach of ion to be subject to equally resistance (
f) impact, for a spheroidal ion of class, obey Stokes' law, that is:
f=6 π r η ν (r is ion particle radius, and η is the solution medium coefficient of viscosity, and ν is ionic transfer speed), when reaching balance, charged ion uniform motion, i.e. F=
f.
Summary of the invention
The object of the invention is to provide a kind of food impregnation processability method of the strong electrolyte gas current of controlling based on function signal, relate to a kind of novel foodstuff impregnation processability method, principle is to generate specific periodic signal waves by function signal generator, through power amplifier, signal code is amplified and is encouraged the coil windings of mutual inductance silicon steel core one end, the induced electromotive force that the magnetic flux changing produces respective change rule in the other end is full of the spiral silicone tube winding pipeline of strong electrolytic solution drives the ion in conducting loop and forms directional migration as " driving source ".Because induced electromotive force Changing Pattern is different, ion is subject to big or small and duration of the electric field force of " forward " and " negative sense " to be had differently, and then makes ion have different stepping effects.According to the ion characteristic of solution system, select suitable function waveform to reach best dipping effect.As shown in Figure 1, waveform example is as Fig. 2 for know-why.
