Abstract
The present invention relates to a method for fabricating crisp winter jujube. The present invention comprises: winter jujube is cleaned, selected and enucleated; the obtained winter jujube is placed in an impregnation tank, and is taken out after being heated for 1 to 6 minutes; the heating temperature is 60 to 90 DEGC; the obtained winter jujube is placed in a basket; the basket is fixed in a centrifugal machine in order to dehydrate the obtained winter jujube; the obtained basket together with the winter jujube is placed in a reaction pot which can be vacuumized; the reaction pot is vacuumized, and the vacuum degree is 0.089 to 0.1MPa; palm oil is filled in the reaction pot synchronously, and is heated to 95 DEGC by steam; the basket together with the winter jujube is deoiled for 1 to 4 minutes after the winter jujube is fried for 0.5 to 1.2 hours; the obtained winter jujube is enclosed by nitrogen through a nitrogen supplier, and is sealed and packaged; the obtained winter jujube is sterilized. The present invention aims to provide delicious crisp winter jujube convenient for storage and transportation.
Description
Technical field
The present invention puts it briefly and relates to a kind of processing method of dry fruit, relates in particular to a kind of preparation method of crisp winter jujube.
Background technology
The winter jujube is a kind of jujube class dry fruit, because its evening in maturity period, so name winter jujube.The winter jujube with its color and luster U.S., mouthfeel is good, fruit is big, juice is many, epidermis is thin, little, crisp sweet good to eat, the crisp no slag of jujube nuclear and enjoy great prestige the four seas, is a kind of extremely famous and precious rare fruit, the height of its nutritive value, rank 260 surplus the hat of kind of jujube class fruit.The single fruit of winter jujube can weigh 48 the gram, its fructose content is about 32.2%, vitamin content 303mg/100g, pectin content are 0.286%, fiber content is 1.747%, iron content is 0.2mg/100g, zinc content is 2.83mg/kg.But the resting period of winter jujube is shorter, and fresh-keeping being difficult for, because the winter jujube is difficult for long term storage under natural environmental condition, the phenomenon of variable color usually can take place, rotting, going bad is not easy to remote transportation, for bringing difficulty in its market of moving towards various places.
Summary of the invention
The object of the present invention is to provide a kind of be convenient to store and transport carry, the crisp winter jujube of delicious flavour.
The preparation method of crisp winter jujube of the present invention comprises the steps:
(1) to the winter jujube clean, select, stoning;
(2) the winter jujube that step (1) is obtained places dipping tank to carry out pulling out after 1-6 minute the blanching, and blanching temperature is 60-90 ℃;
(3) the winter jujube that step (2) is obtained places basketry, basketry is fixed in the centrifuge again it is carried out processed;
(4) basketry that step (3) is obtained places in the retort of vacuum-pumping together together with the winter jujube, be provided with rotating shaft in the described retort, liftably be provided with suspension bracket in the rotating shaft, described basketry is fixed on the suspension bracket, to vacuumizing in the jar, its vacuum is 0.089-0.1MPa, in retort, add palm oil simultaneously and utilize the Steam Heating palm oil to 90-95 ℃, utilize suspension bracket that basketry is placed palm oil together together with the winter jujube, through behind 0.5-1.2 hour fried, basketry is hung palm oil together together with the winter jujube, make rotating shaft drive basketry again and rotate, under vacuum state, the winter jujube is carried out de-oiling and handled 1-4 minute;
(5) the winter jujube that step (4) is obtained takes out from retort and packs after nitrogen is filled with nitrogen charger in the back;
(6) the winter jujube that step (5) is obtained carries out sterilization processing.
Processed substitutes with micro-wave drying in the preparation method of crisp winter jujube of the present invention, wherein said step (3).
The preparation method of crisp winter jujube of the present invention is characterized in that wherein the fried time is 1 hour in the described step (4), and de-oiling was handled 3 minutes.
The preparation method of crisp winter jujube of the present invention, wherein said step (6) is handled for ultraviolet sterilization.
Advantage of the present invention and good effect are: it adopts special process, especially in making the finished product process, increased that palm oil is crossed in blanching, freezing processing, processed, vacuum, vacuum de-oiling is handled, fill the operation of carrying out sterilization processing after packing behind the nitrogen with nitrogen charger, make the crisp winter jujube of producing under natural environmental condition, to store the long period, and be easy to carry, because the temperature of whole process is controlled at below 90 ℃, has kept exclusive local flavor, nutrition and the natural colour of fresh winter jujube.
The specific embodiment
The preparation method of crisp winter jujube of the present invention comprises the steps:
(1) to the winter jujube clean, select, stoning; Stoning can be adopted the manual removal method, also can adopt the mechanical means stoning.
(2) the winter jujube that step (1) is obtained places dipping tank to carry out pulling out after 5-6 minute the blanching, and blanching temperature is 90 ℃; Blanching is the dust for further place to go winter jujube top layer, remaining agricultural chemicals etc.
(3) the winter jujube that step (2) is obtained places basketry, basketry is fixed in the centrifuge again it is carried out processed; Basketry adopts the shaped steel welding to make, and can be cylindrical, also can be conical, or other are convenient to make and easy planform fixing in centrifuge.The winter jujube placed be fixed on centrifuge in the basketry again and carry out processed, the centrifuge that can avoid the winter jujube to be run up is smashed.
(4) basketry that step (3) is obtained places in the retort of vacuum-pumping together together with the winter jujube, be provided with rotating shaft in the described retort, liftably be provided with suspension bracket in the rotating shaft, described basketry is fixed on the suspension bracket, to vacuumizing in the jar, its vacuum is 0.089-0.1MPa, in retort, add simultaneously palm oil and utilize Steam Heating palm oil to 90 ℃, utilize suspension bracket that basketry is placed palm oil together together with the winter jujube, through behind 1 hour fried, basketry is hung palm oil together together with the winter jujube, make rotating shaft drive basketry again and rotate, under vacuum state, the winter jujube is carried out de-oiling and handled 3 minutes;
