Durian Freeze Dryer

Durian freeze dryer

The nutritive value of durian is high, every hectogram of durian contains 2 grams, of protein, 1.2 grams, of fat, 36 grams, of carbohydrate, vitamin B1 one o32 milligram, mono-0.28 milligrams of vitamin A MP.AMp.Amp, 44 milligrams of vitamin B3-1.1 milligram vitamin Cs, 18 milligrams of calcium, 1.1 milligrams of iron, and 56 milligrams, of phosphorus, often edible can improve the health, strengthens immunity, treat dysmenorrhoea, the short appetite of appetizing, defaecation treats constipation, prophylactic treatment hypertension, pre-anti-cancer, grow spleen tonifying Qi, tonifying kidney and strengthening yang, is a kind of fruit that has nourishing effects. Durian is hot in nature, therefore can tremble with fear by Huoxue San ", alleviates female menstrual period pain symptom, is especially applicable to being subject to the women of dysmenorrhoea puzzlement edible. Meanwhile, it is cold and cool that it can also improve the belly, promotes temperature rise, is cold physique person's desirable help the good merchantable brand.

In order to eat durian season non-durian, people carry out durian fried or air-dry preservation mostly, and wherein fried durian piece is tasted and lost crude oil durian taste, and oleaginous taste is dense, and are difficult for preserving, and nutrient loss is serious, outward appearance gross distortion; Heated-air drying durian, because the dry environment is difficult to control, is easily subject to microbial contamination, and directly dry under high ambient conditions, most of the nutritional labeling is destroyed, and process time is longer. The block-shaped shrinkage of heated-air drying durian is serious, and the mouthfeel is very hard, in process, along with nutritional labeling under long-time high-temperature action runs off in a large number, can not preserve for a long time.

The technical problem to be solved in the present invention is to provide a kind of freeze-drying durian preparation method, and the freeze-drying durian goods of the inventive method processing can keep the original shape color, and luster local flavor substantially, nutrient content unchanged, and the shelf-life can reach 3 to 5 years, lightweight is easy to transport.

The present invention adopts the following technical scheme:

A freeze-drying durian preparation method comprises the following preparation process:

A. select without disease and pest, non-rot, eight to ninety percent ripe fresh durians;

B. fresh durian selected in step a is rinsed to cleaning with clear water, washing time is 4 ~ 5 minutes, is then using thimerosal to carry out soaking disinfection sterilization, soak time is 6 ~ 12 minutes, taking-up after immersion completes, re-uses clear water and rinses, until its superficial no residue thimerosal;

C. the fresh durian vertical plane of having been sterilized in step b is cut, take out pulp bag, reject fruit stone;

D. the pulp in step c is carried out to spraying disinfection with alcohol, spray time 6 ~ 11 minutes, the rear draining of having sprayed;

E. the pulp after draining in steps d being finished carries out sabot quick-frozen, and quick freezing temperature, to-6 ℃ ~-8 ℃, then takes outstanding again, standing to pulp central temperature be 0 ℃, then again pulp is carried out to stripping and slicing, carry out freezingly after stripping and slicing completes, cryogenic temperature is-30 ℃ ~-38 ℃;

F. the pulp warehouse entry having frozen in step e is dry, vacuum ranges is controlled at 40pa ~ 90pa, and heating and temperature control is at 55 ℃ ~ 100 ℃, heat time 12h ~ 22h;

G., after having heated, the pulp is encapsulated.

As a preferred technical scheme, the thimerosal described in step b is the Lavelle water of 50ppm ~ 100ppm concentration.

As a preferred technical scheme, the concentration of the alcohol of the use of spraying in step d is 70% ~ 75%.

The invention has the beneficial effects as follows: the freeze-drying durian goods of the inventive method processing can keep original shape color and luster local flavor substantially, nutrient content unchanged, rehydration performance is good, shelf-life can reach 3 to 5 years, lightweight, be easy to transport, the method step of the present invention is comparatively simple simultaneously, without buying specific manufacturing equipment, input cost is comparatively cheap.

The specific embodiment

Below the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art, the protection scope of the present invention is made more explicit by defining.

After testing, the resulting freeze-drying durian of the present invention goods can keep its original shape color, and luster local flavor substantially, nutrient content unchanged, rehydration performance is good, and the shelf-life is lasting, lightweight, is easy to transport.
