Abstract
The present invention discloses dried blueberry fruits and a production method thereof. The production method includes the following steps: (1) trehalose solution process; and (2) vacuum freeze drying process. An ultrasonic treatment is carried out in the presoaking treatment process, expanding the cell membrane permeability of fresh blueberry fruits, and making it easier for trehalose and phosphate to play a protective role on blueberry fruit cells; the trehalose phosphate solution is used for preprocessing the fresh blueberry fruits, playing a protective effect of the trehalose on the blueberry fruit cells and anthocyanidin in the freezing and drying process, and also playing a role of the phosphate in stabilizing natural pigment.
Description
Technical field
The invention belongs to preserved fruit dried fruit technical field, be specifically related to a kind of blueberry dried fruit and preparation method thereof.
Background technology
Blueberry dried fruit, means the meaning of blue berry.One is low shrub, and short pin is wild, and particle is little, but the content of anthocyanidin is very high; The second is artificial culture blueberry, can grow to 240cm high, and fruit is comparatively large, and moisture is more, and anthocyanidin content is relatively on the low side.
Containing abundant nutritional labeling in Blueberry, it not only has good nutrition health-care functions, also has functions such as preventing cranial nerve is aging, cardiac stimulant, anticancer softening blood vessel, enhancing human organism immunity.Blueberry nutrient enriches, and is not only rich in conventional nutrients, but also containing very abundant flavonoids and polysaccharide compound, be therefore otherwise known as " fruit queen " and " king of berry ".Blueberry is that the fruit pulp that a kind of nutritive value is very high is rich in the nutrients such as abundant vitamin, protein and mineral matter, anthocyanin pigments proportion in many fruit of wherein unique in blueberry preciousness is height very, also have in blueberry and be rich in the nutrients such as rich in protein, dietary fiber, fat, vitamin, the nutrient that in blueberry, these are rich in is all higher than the nutrition that other fruit are rich in.Also contain the trace quantity mineral substance elements such as abundant calcium, iron, phosphorus, potassium, zinc in blueberry, these mineral elements there is ratio apparently higher than other fruit.So blueberry is a kind of fruit of high nutrition.
Traditional method makes blueberry dried fruit, is generally by blueberry Exposure to Sunlight, oven dry or freeze drying, and obtained blueberry dried fruit can make blueberry cell and anthocyanidin be destroyed, and anthocyanidin content is low, and mouthfeel is poor.
Summary of the invention
The defects such as blueberry cell and anthocyanidin are destroyed, and anthocyanidin content is low, mouthfeel difference can be made for overcoming existing blueberry dried fruit, the invention provides blueberry dried fruit and preparation method thereof.
The present invention solves the problems of the technologies described above adopted scheme:
The preparation method of blueberry dried fruit, comprises the steps:
(1) aqueous trehalose process: be in the phosphate solution of 0.6-0.8mol/L trehalose by being soaked in trehalose concentration after blueberry fresh fruit wash clean; Soak time is 1-5 hour;
(2) vacuum freeze drying process: the aqueous trehalose after process is put into freeze drying equipment, first be cooled to-50 DEG C, then 15 ~ 30MPa is evacuated to, by so carrying out the intensification of degree sequence, with-45 DEG C ,-40 DEG C ,-35 DEG C ,-30 DEG C ,-25 DEG C ,-20 DEG C each dry 2 hours, finally be dried to fruit water content for 13%-15% with-15 DEG C, obtain blueberry dried fruit.
Preferably, also comprise and select materials before aqueous trehalose process, concrete grammar is by the blueberry selecting maturation, go mouldy without rotten, nothing.
The invention also discloses the blueberry dried fruit obtained by said method.
Implement patent of the present invention, there is following beneficial effect:
(1) the present invention is in the process of dipping pretreatment, has carried out ultrasonic wave process, expands Blueberry membrane passage, makes trehalose and phosphate more easily carry out playing protective effect in fruit cell;
(2) blueberry dried fruit of the present invention and preparation method thereof adopts the phosphate solution of trehalose to carry out pretreatment to blueberry fresh fruit; play trehalose freezing with the protective effect to blueberry cell and anthocyanidin in dry run, play again the effect of phosphate-stabilized natural colouring matter.
