Description
Technical field
The present invention relates to food processing fields, and in particular to a kind of betel nut gas explosion softening process and device.
Background technique
Betel nut, it is nature and flavor Wen Xin, nontoxic, there are the multiple efficacies such as desinsection, broken product, lower gas, row water.There are many containing in Areca
The nutrient and benefit materials of needed by human body, such as organic acid, amino acid, fat, betel oil, alkaloid, catechin, choline
Ingredient, therefore it is properly termed as pure plant chewing gum again.PERICARPIUM ARECAE has expelling parasite, antibacterial, disperse accumulation, stomach invigorating, anti-atherogenic
The effect of hardening, appropriate chewing PERICARPIUM ARECAE body health benefits.
PERICARPIUM ARECAE, quality is hard, eats inconvenience.If fibre stiffness after betel nut processing, can stimulate the mouth of eater
Chamber mucous membrane, unfavorable oral health, therefore need the fibr tissue hard to its to soften before being processed into food.In addition, to Bin
Bulky fibr tissue carries out softening and is conducive to effective component dissolution in PERICARPIUM ARECAE, its effective component can be improved by the utilization of human body
Rate.The method of common softening areca-nut has following several:
(1) enzymatic isolation method, which refers to using cellulase, hydrolyzes softening areca-nut shell, reduces fiber by high pressure-enzymolysis
The tightness of tissue hydrolyzes PERICARPIUM ARECAE fibr tissue under the action of enzyme, to achieve the purpose that softening.Its disadvantage
It is, since the enzyme digestion reaction of cellulase needs specific temperature, pH value and longer enzymolysis time, so enzymatic isolation method produces work
Skill is complicated, operates more troublesome, and will cause betel nut surface and notch fluffing, influences quality of finished.
(2) conventional physical method refers to such as water-extraction method, steams the traditional softening method of profit method.These methods can make obtained
Finished product is harder, influences the flavor and taste of betel nut, causes the loss of effective components in betel nut, and difficult by the interior life in betel nut original seed
Bacterium kills, and goes mouldy to cause betel nut product.
(3) chemical method refer to sodium hydroxide solution handle betel nut, so that hydroxy combining power in betel nut fiber is died down, in conjunction with
The ability of moisture is kept to increase, hardness becomes smaller, and betel nut is soft, and flexibility increases, and anti-degree of grinding increases.Shortcoming is chemical method
It not only can cause environmental pollution, can also make residual chemicals in betel nut, threaten the health for the person of disappearing.
In place of the equal Shortcomings of the method for above-mentioned softening areca-nut fibr tissue, betel nut secondary industry is constrained to a certain extent
Development.
