Fruit jelly preparation method with short production cycle
Technical field
What the present invention relates to is field of food, specifically is a kind of fruit jelly preparation method with short production cycle.
Background technology
Fruit jelly all needs to produce by salt marsh and two steps of sugaring usually, salt marsh often needs tens of days, sugaring is also wanted the time of several days, the production cycle of fruit jelly is all long like this, and need a large amount of places to carry out salt marsh and sugaring, be unfavorable for fruit jelly production, objectively also increased the cost of fruit jelly.
Summary of the invention
The objective of the invention is on the basis that does not change the fruit jelly taste, a kind of fruit jelly preparation method with short production cycle is provided.
A kind of fruit jelly preparation method with short production cycle is characterized in that, comprises following production stage:
(1) with clear water rinsing fresh fruit raw material;
(2) fruit raw material is pulled out drain well;
(3) get sodium alginate and water by weight 1:100 and mix, add sodium acid carbonate furnishing pH value then and be 9~10 sodium alginate solution, fruit raw material was immersed sodium alginate solution 12~14 hours, the sodium alginate solution consumption gets final product with the submergence fruit raw material;
(4) get the fruit raw material that soaked sodium alginate solution in salt, the step (3) and 2~4 ℃ water is blended into salt marsh liquid by weight 1:8:10, and keep the salt marsh liquid temp be 2~4 ℃ 10~12 hours;
(5) salt marsh liquid is warming up to 60~65 ℃ in 20~30 minutes, and is incubated 30~40 minutes;
(6) again salt marsh liquid is cooled to 2~4 ℃ rapidly in 10 minutes, and is incubated 10~12 hours;
(7) repeating step (5)~(6) operation is 2~3 times, and the stain liquid that then the fruit raw material drop desalted shone system 5~7 days in the threshing ground;
(8) get fruit raw material and the water that solarization was made in white granulated sugar, the step (7) by weight 1:10:10 and be blended into sugaring liquid, soaked 12~14 hours;
(9) then sugaring liquid was warming up to 70~80 ℃ in 20~30 minutes, in this temperature-rise period, add the white granulated sugar of sugaring liquid weight 2~3% in the step (8), and constantly stir, after 30~40 minutes, in 20 minutes, be cooled to room temperature in 70~80 ℃ of insulations more then;
(10) repeating step (9) operation is 2~4 times, with fruit raw material drop desaccharification stain liquid, is dried to water content 13~25% then, makes the fruit jelly product through packing.
Described room temperature is 20~35 ℃.
The present invention soaks fruit raw material by using sodium alginate solution, make fruit raw material carry out can preventing from well becoming fragile in salt marsh and the sugaring in follow-up heating and cooling repeatedly, reduce the pulp dialysis effectively, both ability boil, anti-bubble, can absorb liquid glucose well again, keep original taste simultaneously.And salt marsh and sugaring are carried out in heating and cooling repeatedly, and the whole production cycle is shortened greatly; Temperature-rise period constantly adds an amount of white granulated sugar in the step (9), the concentration that can replenish sugaring liquid well, and fruit jelly is easier absorption sugaring liquid also, makes the fruit jelly taste better.
The fruit jelly that the present invention makes is compared with the fruit jelly that conventional method is made, and has reduced salt marsh and sugaring soak time, has kept the original taste of fruit jelly and nutrition well, the excellent taste of food; And the production cycle only be about 10 days, can shorten the production cycle of fruit jelly greatly, reduce salt marsh and the required place of sugaring, save a large amount of production costs.
The specific embodiment
The present invention will be described in detail to reach Comparative Examples by the following examples.
Embodiment:(1) with clear water rinsing fresh fruit raw material;
(2) fruit raw material is pulled out drain well;
(3) get sodium alginate and water by weight 1:100 and mix, add sodium acid carbonate furnishing pH value then and be 9 sodium alginate solution, fruit raw material was immersed sodium alginate solution 12 hours, the sodium alginate solution consumption gets final product with the submergence fruit raw material;
(4) get the fruit raw material that soaked sodium alginate solution in salt, the step (3) and 2 ℃ water is blended into salt marsh liquid by weight 1:8:10, and keep the salt marsh liquid temp be 2 ℃ 11 hours;
(5) salt marsh liquid is warming up to 62 ℃ in 25 minutes, and is incubated 35 minutes;
(6) again salt marsh liquid is cooled to 2 ℃ rapidly in 10 minutes, and is incubated 11 hours;
(7) repeating step (5)~(6) operation is 2 times, and the stain liquid that then the fruit raw material drop desalted shone system 6 days in the threshing ground;
(8) get fruit raw material and the water that solarization was made in white granulated sugar, the step (7) by weight 1:10:10 and be blended into sugaring liquid, soaked 11 hours;
(9) then sugaring liquid is warming up to 75 ℃ in 25 minutes, in this temperature-rise period, adds the white granulated sugar of sugaring liquid weight 2% in the step (8), and constantly stir, after 35 minutes, in 20 minutes, be cooled to room temperature in 75 ℃ of insulations more then;
(10) repeating step (9) operation is 3 times, with fruit raw material drop desaccharification stain liquid, is dried to water content 20% then, makes the fruit jelly product through packing.
The fruit jelly that present embodiment is made has kept the original taste of fruit jelly and nutrition well, the excellent taste of food, and pulp is complete.
Comparative Examples:Different with embodiment is, does not use sodium alginate solution to soak fruit raw material, makes the fruit jelly of Comparative Examples 1.The fruit jelly mouthfeel that Comparative Examples is made is poor, and pulp is cracked mostly.
