Abstract
The invention provides a production method for frozen celery. The moisture content of celery is reduced by microwave drying, the aerobic respiration of the celery is reduced or even stopped, and the aging speed of the celery is retarded; the celery is soaked in a color protection liquid to maintain a good color and a good appearance after being frozen for a long time; bacteria on the surface of the celery can be killed by steam; and a suitable freezing temperature not only can prevent the celery from a frost damage but also can guarantee a longer preservation time. The frozen celery can be readily used just by unpacking the frozen celery, and is convenient and healthy, and can bring great convenience to daily lives of people.
Description
Technical field
The present invention relates to a kind of production method of freezing celery.
Background technology
Refrigerated vegetables are a kind of of frozen food, and it is after to be fresh vegetables through processing handle, with alap temperature and the speed prepacked food that freezes to make as soon as possible.This processing method makes the moisture in the vegetables form rule very soon and tiny ice crystal is dispersed in the cell equably, and vegetable tissue can be not destroyed, and the Biochemical processes of vegetables inside simultaneously can't be carried out again, so bacterium, mould can't grow.The quick-frozen vegetable edible is taken indoor need not and washed, cuts with very convenient, thaws a little, and is namely ripe in a twinkle with the very hot oven culinary art, and its taste, color and luster and vitamin content etc. are very nearly the same with fresh vegetable.
Summary of the invention
The object of the invention is to disclose a kind of production method of freezing celery, by microwave drying, protect look and sterilization, makes the freezing preservation that spinach can the long period can also keep appearance color preferably.
The present invention is achieved by the following technical solutions:
A kind of production method of freezing celery may further comprise the steps:
(1) celery is extractd Huang Yehou, clean with flowing water, carry out micro-wave vacuum then, temperature is controlled under 40-50 ℃, stops drying when the water content of spinach is reduced to 60-65%;
(2) celery that drying is crossed is at calcium chloride: potassium sorbate: Radix zanthoxyli water extract: soaked 8-10 minute in the colour protecting liquid of the ratio 1-2:1-2:1-2:1000 of water, protect look;
Described Radix zanthoxyli water extract is to adopt 6-8 times of water gaging of Radix zanthoxyli, decocts 1-3 hour, and filter residue obtains after concentrating;
(3) protect celery behind the look with 100 ℃ steamed 3-5 minute, to kill the bacterium except the celery surface;
(4) after celery takes out, the inflated with nitrogen packing, celery is put into 3-8 ℃ of storehouse precooling 3-4 days;
(5) change at-2-0 ℃ following freezing.
Advantage of the present invention is:
The invention provides a kind of production method of freezing celery, reduce the moisture of spinach by microwave drying, reduce or even stop the aerobic respiration of celery, slow down the celery aging rate; Make celery after long-time freezing, color outward appearance preferably can also be arranged by the colour protecting liquid immersion; Steam can be killed the spinach surface bacteria; Suitable cryogenic temperature can guarantee that spinach can freezingly can not guarantee the long holding time again.This product is namely torn i.e. usefulness open, and is convenient, healthy, brings convenience for people's daily life.
The specific embodiment
Embodiment
A kind of production method of freezing celery may further comprise the steps:
(1) celery is extractd Huang Yehou, clean with flowing water, carry out micro-wave vacuum then, temperature is controlled under 50 ℃, is reduced to the water content of spinach to stop drying at 60% o'clock;
(2) celery that drying is crossed is at calcium chloride: potassium sorbate: Radix zanthoxyli water extract: soaked 8 minutes in the colour protecting liquid of the ratio 2:1:1:1000 of water, protect look;
Described Radix zanthoxyli water extract is to adopt 6 times of water gagings of Radix zanthoxyli, decocts 1 hour, and filter residue obtains after concentrating;
(3) protect celery behind the look with 100 ℃ steamed 5 minutes, to kill the bacterium except the celery surface;
(4) after celery takes out, the inflated with nitrogen packing, celery is put into 8 ℃ of storehouse precoolings 3 days;
(5) change at-2 ℃ of following freezings.The invention provides a kind of production method of freezing celery, reduce the moisture of spinach by microwave drying, reduce or even stop the aerobic respiration of celery, slow down the celery aging rate; Make celery after long-time freezing, color outward appearance preferably can also be arranged by the colour protecting liquid immersion; Steam can be killed the spinach surface bacteria; Suitable cryogenic temperature can guarantee that spinach can freezingly can not guarantee the long holding time again.This product is namely torn i.e. usefulness open, and is convenient, healthy, brings convenience for people's daily life.
