Description

Loquat preserved fruit and preparation method thereof
Technical field
The present invention relates to field of food, more particularly to a kind of preparation method of preserved fruit.
Background technology
Loquat is the fruit of rosaceous plant loquat, also known as reed tangerine, Lu Zhi, golden ball, scorching fruit, thick visitor, burnt son etc., it is a kind of The fruit of the plant with edibility and medical value, is the distinctive fruit of south China, belongs to early spring fruit, existing so far The history of more than 3000 years.Loquat is distributed in south of the River each province, and Soviet Union, Zhejiang, Fujian are the main place of production.Criticize in 9~November of florescence, Fruiting period 4~May of next year.Batch fruit in ellipse long, it is covered with fine hair on faint yellow or orange-yellow crust, in pulp There is fraction of seed.Sweet and sour and succulence fragrance is good to eat, be the treasure in fruit, contain various nutrients such as carbohydrate, fat, albumen Matter, carrotene etc..
Because loquat picking time is short, inconvenience is preserved and transported for long-distance.Although various modern saving and processing technologies can reduce Pi Rake fruit postharvest decay, extends shelf-life, but in storage, loquat easily occurs nutritive value reduction and pulp The symptoms such as lignifying, be mainly shown as nutritional ingredient degraded, pulp be hardened, pericarp hardly possible stripping, fruit lopside, fruit juice reduction etc..Cause This, loquat intensive processing is always the focus of fruits and vegetables area research in recent years.
Preserved fruit is the distinctive traditional food of China.Candied fruit is carried out pickled with various water fruits and vegetables as raw material with sugar etc. Or after cooking, by drying or without drying, with certain form, sparkling and crystal-clear, full, tool gloss, a translucent tack-free class Sugar prod.The basic technology of the processing of fruit is:Sorting, hardening, color protection, ooze sugar, dry.Wherein, sugar and back tender are oozed Skill is most important.
The paper that Liu Hong et al. is delivered《The processing of low sugar Chinese lute preserved fruit》, a kind of processing method of loquat preserved fruit is disclosed, Including raw material arrangement, cleaning, cutting, stoning, color protection, blanching, hardening, strike-through, vacuum sugar infiltration, drying, cooling, packaging and finished product Several steps.But, the technology is excessively single as liquid glucose, mouthfeel is oozed using white sugar and starch syrup.In addition, heated-air drying Far from the requirement for meeting consumer and pursuing first-class quality, the color of heated-air drying product, nutrient, thermal sensitivity and easily The biological active component of oxidation can not preferably be retained.
The content of the invention
Liquid glucose is oozed it is an object of the invention to provide a kind of loquat, one of its primary raw material prepared as loquat preserved fruit, Can reconcile the taste of loquat preserved fruit.The second object of the present invention is the preparation method for providing loquat preserved fruit, and the method is simple, institute The loquat preserved fruit of preparation is nutritious, and sense organ is good.
To achieve the above object, the technical scheme is that:Loquat oozes liquid glucose, and every 100 parts ooze in parts by weight Liquid glucose is composed of the following components:25-50 portions of sucrose, 0.1-0.5 parts of citric acid, balance of water.
Further, loquat oozes liquid glucose, in parts by weight every 100 parts to ooze liquid glucose composed of the following components:30 parts of sugarcanes Sugar, 0.3 part of citric acid, balance of water.
Further, described loquat oozes liquid glucose, in parts by weight every 100 parts to ooze liquid glucose composed of the following components:45 Part sucrose, 0.2 part of citric acid, balance of water.
The method that liquid glucose prepares loquat preserved fruit is oozed with any one loquat, following steps are specifically included:
Loquat fruit is carried out into color retention with color stabilizer, and carries out blanching 1-5 minutes in boiling water, after cooling with hard Agent carries out cure process, after cleaning unnecessary curing agent, obtains loquat fruit pretreatment material;
B vacuum sugar infiltrations
Under conditions of being 30-50 DEG C in temperature, liquid glucose is oozed by way of vacuum sugar infiltration by step A gained with the loquat Loquat fruit pretreatment material ooze sugar treatment to loquat fruit and is translucent shape, must ooze sugared loquat fruit;
C dried process
Step B gained is oozed into sugared loquat fruit to be dried with microwave vacuum drying process, micro-wave vacuum parameter is true Reciprocal of duty cycle 0.04-0.08MPa, microwave intensity 2-8W/g, 10-45 minutes micro-wave vacuum time, dry to oozing sugared loquat fruit Middle moisture weight content is 13-20%, obtains loquat preserved fruit.
Further, described loquat oozes the method that liquid glucose prepares loquat preserved fruit, it is characterised in that:It is described in step A Color retention be specially:Loquat fruit is put into mass percent for 0.2% citric acid and mass percent are 0.3% sub- Soaked 1 hour in niter cake mixed solution.
Further, described loquat oozes the method that liquid glucose prepares loquat preserved fruit, it is characterised in that:It is described in step A Curing agent is the calcium chloride that mass percentage concentration is 0.5% and the mixed solution of the sodium chloride that mass percentage concentration is 0.5%, The time of the cure process is 12-15 hours.
Further, described loquat oozes the method that liquid glucose prepares loquat preserved fruit, it is characterised in that:In step B, true Reciprocal of duty cycle be 0.08mPa under conditions of carry out vacuum sugar infiltration treatment.
Further, described loquat oozes the method that liquid glucose prepares loquat preserved fruit, it is characterised in that:In step C, dry Moisture weight content is 13-20% into oozing sugared loquat fruit, obtains loquat preserved fruit.
Further, the loquat preserved fruit that will be prepared is encapsulated with high-temperature retort bag.
Loquat preserved fruit prepared by above-mentioned method.
The beneficial effects of the present invention are:Loquat preserved fruit of the invention is that loquat is processed by saccharification, forms mouthfeel Suitable food, overcomes the defect of the unsuitable long-term storage of loquat, makes full use of loquat resource, improves resource utilization and Pi The economic worth of rake;The shunting of loquat affluence yield can also effectively be solved, it is to avoid caused price is concentrated in the listing of production peak phase Too low problem, can increase planting loquat and sale, increase economic efficiency.And it with loquat, sucrose, citric acid etc. is main former to be Material retains the effective ingredient of loquat through science process technology, reaches i.e. nutrition and health care and the suitable food of mouthfeel.Finally adopt High-temperature retort bag, also known as soft tank packaging bag, is that plastic sheeting, metal foil or their composite are made with airtight The sack of property and light-proofness.By the way that after molten heat seal, pressurized, heated is sterilized, for containing finished food.
Gained loquat preserved fruit color and luster of the invention, flavor-stable;In addition to the effect for possessing general preserved fruit, while also having profit Lung, heat clearing function.
Specific embodiment
