Abstract

A technology for preparing high-pH canned bamboo shoot from fresh bamboo shoot includes such steps as choosing raw material, steaming, rinsing in cold water, removing shell, shaping, loading in cans, sterilizing, cooling, sudden freezing at -13- -16 deg.C for 1-2 hr, and cold storage.

Description

The preparation method of high pH value bamboo shoots

Technical field

The present invention relates to food processing technology field, particularly a kind of preparation method of high pH value bamboo shoots.

Background technology

Cellulose and amino acid whose pure natural, pollution-free green food are rich in bamboo shoots systems.Because its fiber content height, many foods can promote digestion, " street cleaner " of the human body that is otherwise known as.Bamboo shoot product is of high nutritive value, be fry, stewing, stew, pot all is the good merchantable brand on the dining table, ancient times just has the good reputation of " vegetarian diet first product ".High pH value bamboo shoots, bamboo shoot meat bamboo shoot fringe is yellow-white or faint yellow, and bamboo shoot meat is tender and solid, and is flexible slightly, and the bamboo shoot fringe is tender and tight, is loved by all superior food.Existing canned high pH value bamboo shoots, product has tart flavour, and mouthfeel is not good, does not very behave and likes, and technology is not advanced when producing, and the technological process required time is longer, generally needs 24 hours just can produce product, therefore yielding poorly of manufacturing enterprise, the cost height, and then cause deficiency in economic performance.

Summary of the invention

The object of the present invention is to provide a kind of shortened process greatly, and product can keep peculiar tastes such as the natural flavors of bamboo shoot and bright, crisp, perfume (or spice), mouthfeel is good, the preparation method of the high pH value bamboo shoots that added value of product is high.

The objective of the invention is to be achieved through the following technical solutions: high pH value bamboo shoots,----boiling----cold floating------------tinning----sterilization----cooling----chilling----warehouse-in refrigeration that clothing is removed in shaping of peeling off that its technological process of production is for selecting materials.Its key problem in technology is: after the tinning goods are carried out secondary, sterilization in open kettle, steam pressure is 4mpa, and the water temperature of sterilization for the first time is 100 ℃, and the time is 20-60 minute, mends full gate water after the sterilization for the first time, seals, and carry out the sterilization second time immediately; The water temperature of sterilization for the second time is 100 ℃, and the time is 10-60 minute; Can after the sterilization cools off with circulating water, is no less than 30 minutes cool time, and the tank body central temperature is reduced to about 30 ℃; It is that-13～-16 ℃ low temperature storehouse is beaten and carried out chilling in cold 1-2 hour that cooled tank body is put into temperature rapidly, and the tank body central temperature is reduced to about 5 ℃ as early as possible.

The present invention compared with prior art has following advantage:

1. the high pH value bamboo shoots of producing with the inventive method can keep peculiar tastes such as the natural flavors of bamboo shoot and bright, crisp, perfume (or spice), does not have tart flavour.

2. produce the technological process of high pH value bamboo shoots with the inventive method and shorten greatly, can finish in 10 hours from the finished product of selecting materials to, production output can increase substantially.

3. the high pH value bamboo shoots of producing with the inventive method, since best in quality, sell well, and added value of product height, and sale price improves nearly 70% than existing product.

The specific embodiment

A kind of high pH value bamboo shoots,----boiling----cold floating------------tinning----sterilization----cooling----chilling----warehouse-in refrigeration that clothing is removed in shaping of peeling off that its technological process of production is: select materials.Adding man-hour, at first the high-quality bamboo shoots fresh, that body is full are put into steam copper, is that 100 ℃, steam pressure are under the condition of 4mpa boiling 40-50 minute in water temperature, pulls out then with circulating water and cools off rapidly and continue with the circulating water rinsing more than 6 hours.Cutting thick old bamboo shoot head with cutter more also scratches bamboo shoot shell top layer along tender tips of bamboo shoot direction, and peel off 1/3 bamboo shoot shell, but keep the bamboo shoot shell of tender tips of bamboo shoot portion (full bamboo shoot long 50%) here, remove the tender clothing of not being with on the bamboo shoot shell part then, with the sheet cutter bamboo shoot head and bamboo shoot tail are repaired again, can not injure the tender tips of bamboo shoot, and peel off the thick shell of bamboo shoot tail to the tender clothing of bamboo shoot.Go into jar after then bamboo shoot shape size bamboo shoot about equally being weighed, clean, and contain 1/3 jar clear water and put into steam copper and carry out the secondary sterilization in open kettle, steam pressure is 4mpa.Tank body sterilization under uncovered situation for the first time, water temperature is 100 ℃, the steam time is 20-60 minute.After carrying out the sterilization first time, after tank body mended full gate water and sealing, under 100 ℃ of water temperature situations, steam and carried out the sterilization second time in 10-60 minute immediately.Again the tank body after sterilization is cooled off with circulating water, be no less than 30 minutes cool time, the tank body central temperature is reduced to about 30 ℃.Put it into temperature then and be-13～-16 ℃ low temperature storehouse and beat and carried out chilling in cold 1-2 hour, the tank body central temperature is reduced to about 5 ℃ as early as possible, can put into temperature and refrigerate standby for-1～3 ℃ storehouse.

Claims

1, a kind of preparation method of high pH value bamboo shoots, its technological process of production is for selecting materials, and------------peeling off,----clothing is removed in shaping, and----------------chilling----warehouse-in refrigeration is characterized in that cold floating: be that 4mpa, water temperature are to carry out re-pasteurization under 100 ℃ of conditions to handle with goods at steam pressure after the tinning in cooling in sterilization in tinning in boiling; Can after the sterilization cools off with circulating water, is no less than 30 minutes cool time, and the tank body central temperature is reduced to about 30 ℃; It is that-13 ~-16 ℃ low temperature storehouse is beaten and carried out chilling in cold 1-2 hour that cooled jar is put into temperature rapidly, and the tank body central temperature is reduced to about 5 ℃ as early as possible.

2, the preparation method of a kind of high pH value bamboo shoots according to claim 1, it is characterized in that: during re-pasteurization, be uncovered sterilization for the first time, sterilizing time is 20-60 minute, after finishing sterilization for the first time tank body is mended full gate water seal mouth, carry out the sterilization second time immediately, sterilizing time is 10-60 minute.
