The invention discloses a kind of processing methods of flue fruit powder, comprising the following steps: the pretreatment of S101 dragon fruit: pericarp chopping is spare, and sarcocarp section is spare；S102 pericarp soluble fibre extracts: impregnating, enzymatic hydrolysis, concentration, precipitating；S103 pulp deseeding processing: enzymatic hydrolysis, activation, filtering；S104 mixing homogeneous: deseeding pulp, soluble dietary fiber powder, beta-cyclodextrin are stirred into homogeneous by a certain percentage；S105 dries finished product: setting specified pressure, temperature, wind-force are spray-dried.Using a kind of processing method of flue fruit powder provided by the present invention, simple process, insoluble matter is reduced by the extraction of pericarp dietary fiber, the processing of pulp deseeding, to improve texture and mouthfeel, by the mixing homogeneous of pericarp dietary fiber and deseeding fruit juice, cooperation spray drying processes the fruit powder that water content is no more than 2%, while relatively retaining the nutritional ingredient of dragon fruit pulp and pericarp comprehensively.
Description
Technical field
The present invention relates to fruit field of deep more particularly to a kind of flue fruit powders and its processing method.
Background technique
Dragon fruit (Hylocereus undulatus) also known as Hylocereus undatus, Green Dragon fruit, pitaya fruit, sweet heart fruit etc. are celestial being
Palm section triangular prism category (Hyloeereus) is concerned, dragon fruit nutrition in recent years as a kind of new fruit tree in many tropical and subtropical countries
Abundant, meat is soft, taste is fragrant and sweet, in good taste, while having the healthcare functions such as reducing blood lipid, hypoglycemic, beauty treatment, can not only make fresh
Drinking water fruit may further be used to a variety of nourishing and health foods such as processing fruit juice, fruit juice, fruit wine, fruit vinegar, Yoghourt, preserved fruit, ice cream, can
Product.Dragon fruit is divided into red skin and white flesh, red skin red meat, Calusena lansium plain boiled pork three classes, wherein red skin red meat kind mouthfeel and nutritive value are most
Good, every 100 g of dragon fruit contains irony about 0.8mg, anthocyanidin about 45mg, Betacyanins about 28mg, dietary fiber about
1.3mg, Betacyanins and dietary fiber have the effect of inhibiting cancer cell, anti-inflammatory, anthocyanidin and irony mainly from pericarp
The irony abundant in pulp, dragon fruit, contributes to form the important source material of ferroheme, and anthocyanidin abundant can prolong
Slow blood vessel aging, has effects that reduce blood pressure, dietary fiber abundant being capable of prevent constipation there are also Betacyanins abundant.
Since fruit powder has nutrient composition content high, moisture content is low, small in size, easy to carry, and have a wide range of application equal spies
Point, therefore the Research on processing technology of flue fruit powder starts one upsurge.Patent CN201610676880.3 discloses a kind of flue
Fruit powder and its processing method choose sufficiently mature dragon fruit, deseeding, skin and flesh, using pulp as raw material, using spiral juice extractor
Juicing, colloid mill fine grinding, homogenizer homogeneous, and appropriate maltodextrin, beta-cyclodextrin and CMC are added in feed liquid, prepare flue
Fruit powder.Patent CN201610894805.4 discloses a kind of method for preparing the instant dry powder of dragon fruit, will pick fresh flue
Fruit is cleaned, and removes the peel, and slice is impregnated with sodium chloride and ascorbic acid colour protecting liquid, squeezed the juice using juice extractor, obtain dragon fruit Normal juice；Add
Enter mixed enzyme to be digested；Juice after enzymatic hydrolysis is by being dried in vacuo to obtain concentrate, and using vacuum refrigeration, microwave disinfection is cold
But it to room temperature, packs to get dragon fruit instant powder.The method of the present invention is by color protection treatment, enzymatic hydrolysis, vacuum freeze drying
Flue fruit powder obtained.
Currently available technology rests on mostly by fresh dragon fruit pulp simply through drying, powder the deep processing of dragon fruit
Flue dry powder is made in broken technique, and since Dragonfruit Juice sugar content is high, fruit powder is in flow regime, it is difficult to which obtained aridity conforms to
Ask and loose flue fruit powder, and pure pulp there are process be more than 60 degree be easy brown stains, fruit seeds removal does not cause mouth completely
Feel bad, after-ripening brown stain leads to problems such as the shelf-life short.
Summary of the invention
In view of this, solving existing in the prior art ask the present invention provides a kind of processing method of flue fruit powder
Topic.
The present invention provides a kind of processing methods of flue fruit powder, comprising the following steps:
S101: dragon fruit pretreatment
The mature red skin dragon fruit of fresh red heart is cut off into leaf, clean, peeling obtains pulp and pericarp respectively, by flue
Pericarp chopping is spare, and flue pulp is cut into slices shape, cryo-conservation is placed in；
S102: the extraction of soluble dietary fiber
The NaOH aqueous solution of low concentration is added toward the pericarp of S101, is stirred in water bath, cellulase degradation is added, after
It is centrifuged after being cooled to room temperature, takes the resulting supernatant heating evaporation concentration of centrifugation, the anhydrous second of 4 times of volumes is added to concentrate solution
Alcohol is stood, centrifugation, is recycled sediment and is dried, i.e. acquisition soluble dietary fiber powder；It is pre- by low-concentration sodium hydroxide
Processing, makes fibrous raw material sky ask loosely organized contact conducive to enzyme with raw material, by cellulose degraded cellulose, is allowed to turn
It is melted into the monosaccharide or oligosaccharides of small molecule, improves the yield of soluble dietary fiber.
S103: pulp deseeding processing
Pulp into S101 step is added the distilled water of 3 times of its weight, 0.2% cellulase and 0.2% pectin
Enzyme stirs evenly, after activate 30min in 50 DEG C of water-baths, filtering obtains fruit juice；
S104: mixing homogeneous
The soluble dietary fiber powder that the S102 of its weight 10% is extracted, 0.2% β-is added in the fruit juice prepared into S103
Cyclodextrin, stirring homogeneous obtain blended fruit juice；
S105: dry finished product
Blended fruit juice is spray-dried with high-pressure spraying equipment, cools down, pack.
S102 step is specifically, it is 0.5%NaOH solution that 20kg mass concentration, which is added, in the pericarp of 5kg S101, at 50 DEG C
Stir process 0.5h in water bath adds 0.2kg cellulase degradation 2h, with the revolving speed of 4000r/min after being cooled to room temperature
It is centrifuged 20min, takes the resulting supernatant heating evaporation of centrifugation to the 1/3 of original solution volume, 4 times of volumes is added into concentrate solution
Dehydrated alcohol, stand 60min, centrifugation, recycling sediment simultaneously dry, i.e., acquisition pericarp soluble dietary fiber powder.
The parameter being spray-dried in S105 step is that feeding temperature is 60 DEG C, atomizing pressure 200kPa, inlet air temperature
200 DEG C, 70 DEG C of leaving air temp, air quantity 1.5m3/min。
Preferably, pulp holding time longest under conditions of 5 DEG C.
On the other hand flue fruit powder of the water content no more than 2% of a kind of merger pulp and pericarp nutrients is provided.
Using a kind of processing method of flue fruit powder provided by the present invention, simple process passes through pericarp dietary fiber
Extract, the processing of pulp deseeding reduces insoluble matter, to improve its texture and mouthfeel, by the mixed of pericarp dietary fiber and deseeding fruit juice
Homogeneous is closed, cooperation spray drying processes the fruit powder that water content is no more than 2%, especially activates in flue pulp step at 50 DEG C
30min filtering, on the one hand removes most of fruit seed residue by filtering, on the other hand reduces high-temperature heating concentration or enzymolysis time
The too long destruction to pulp nutriment.
Pericarp soluble dietary fiber and pulp are mixed in proportion, not only solve dragon fruit pulp sugar content height,
Viscosity is big, is not easy dry problem, and retains the nutritional ingredient of dragon fruit pulp and pericarp comprehensively, improves dragon fruit utilization
Rate.
