Abstract
The present invention discloses a technique for preparing instant banana fruit juice powder. The technique comprises the following steps that 1. a mature banana is peeled and cut into segments, is put in a microwave oven and is sterilized, 2. the sterilized banana slices are pulped, then are added to a fruit pulp enzyme, are enzymolyzed, are separated by a centrifuge and are filtered to obtain banana fruit juice, and 3. an embedding medium is added in the obtained banana fruit juice, is stirred, is homogenized and is dried by spraying. In the present invention, polyphenol oxidase generated through the enzymatic browning of bananas is passivated or inactivated through microwave treatment, and consequently, the oxidation action of a phenol substance is decelerated, and the generation of melanin is reduced. Browning avoids being generated in the processing process, so the embedding rate of the obtained banana juice powder microcapsule reaches 94.4%. The present invention has the advantage of good solubility, the product is yellowish, and the heavy flavour of the bananas is maintained.
Description
Technical field
The present invention relates to a kind of quick dissovled banana dried fruit juice preparation technology.
Background technology
Banana is one of famous fruit, and fragrant and sweet good to eat, old children is all suitable, contains mineral nutrition and multivitamins such as abundant carbon aquation platform thing, crude fibre, pectin and calcium, phosphorus, iron in the fruit, and nutritive value is very high.The southern banana aboundresources of China, still blank basically to the deep processing and utilization of banana resource, mainly to eat raw; In the existing process technology, it is with freezing and vacuum dehydrating at lower temperature method banana meat to be dried, pulverized that banana is made powder, because required apparatus expensive, the energy consumption that yields poorly is big, and this method is difficult to extensive employing.Because banana is rich in pectin, tannin, carbohydrate and various enzyme, not only be difficult to store and transportation, and also very easily brown stain in process, cause the bad change of color, nutrition and local flavor, have a strong impact on the quality of product; A large amount of existence of pectin and carbohydrate cause certain difficulty to processing and utilization simultaneously.
Summary of the invention
The object of the present invention is to provide and a kind ofly can suppress brown stain, keep banana nutrition and local flavor and the simple quick dissovled banana dried fruit juice of technology preparation technology
Above-mentioned purpose can realize by following technical measures: the present invention includes following steps:
A, with after the ripe banana peeling segment, place micro-wave oven to carry out microwave deactivating enzyme and handle;
B, add the pulp enzyme through the banana chip making beating back of the enzyme that goes out and carry out enzymolysis, again through centrifugal, separate, filter and obtain banana fruit juice;
C, gained banana fruit juice add embedding medium, stir, homogeneous, spray-drying again, promptly get the quick dissovled banana dried fruit juice finished product that keeps the original color and luster of banana, local flavor and nutrition.
The detailed process that microwave deactivating enzyme is handled among the step a of the present invention is: the fragment that ripe banana peeling is cut into 1cm～4cm, put into the tray of microwave oven that power is 600W～1000W, carry out microwave treatment 34～60s, make the polyphenol oxidase enzymatic inactivation inactivation in the banana, thereby suppress the enzymatic browning of banana.
The detailed process of step b of the present invention is: will be through adding the sodium hydrogensulfite of its 0.05～0.3% percentage by weight and the cysteine of 0.05～0.3% percentage by weight in the banana chip of the enzyme that goes out, in tissue mashing machine, smash 0.1～1min to pieces through the 2000r/min tissue, the pulp enzyme that adds 0.03～0.08% percentage by weight again, in the stainless steel closed container at 30～50 ℃ of following enzymolysis 3～4h; With the centrifugal 8～15min of the rotating speed of 5000 commentaries on classics/min, get clear liquid and obtain banana fruit juice after filtration.
Embedding medium among the step c of the present invention by maltodextrin and soybean protein by 1～3: 0.5～1.5 weight portion mixes; To add embedding medium be 10～30% of bananas juice weight.
Carry out homogeneous with homogenizer among the step c of the present invention, homogenization pressure 25～35MPa, homogeneous number of times 3～5 times.
Carry out spray-drying with pneumatic atomizer among the step c of the present invention, the air inlet wind-warm syndrome is 60～80 ℃ of 160～200 ℃, leaving air temp.
The present invention compared with prior art has following advantage:
1, adopt microwave treatment can make polyphenol oxidase enzymatic inactivation or the inactivation that causes the banana enzymatic browning, thereby the oxidation of slowing down aldehydes matter reduce melanic generation, makes and avoids producing brown stain in the process.Shorter than traditional blanching enzymatic process required time that goes out, and can alleviate the bad change of banana flavor and the loss of nutrition;
2, by with pulp enzyme liquefaction banana pulp, can improve banana fruit juice crushing juice rate, and obtain clear juice simultaneously, make it have better smell and mouthfeel;
3, the microcapsule embedded rate of banana dried fruit juice that obtains reaches 94.4%, and its dissolubility is good; The product color that makes is faint yellow, has kept the strong local flavor of banana, and powder has good flowability and good instant capacity.
The contained nutritional labeling of banana dried fruit juice sees Table 1, table 2.
