Abstract
The invention discloses a loquat dietary fiber vegetable and fruit sheet and a preparation method thereof. The method comprises the following steps: first blending, second blending, heat treatment, traying, freeze drying, and packaging to obtain a product. The loquat dietary fiber vegetable and fruit sheet is in dark yellow, slightly sweet and slightly acidic, and packaged by high barrier plastic, and has a shelf-life of 8 months, dietary fiber content of 80-90%, calcium content of 1ppm-2 ppm and iron content of 1-2 ppm. According to the invention, the fruit residue left from the production of loquat concentrated juice is selected as a main raw material, and mixed with nutrients comprising calcium gluconate and ferrous lactate, so as to prepare a low-calorie and high-dietary fiber health food product with function of supplementing calcium, and iron.
Description
Technical field
The invention belongs to the fruit and vegetable product field, be specifically related to a kind of loquat dietary fiber vegetables and fruits sheet and preparation method thereof.
Background technology
At present, all pomace is abandoned as the waste material thing during domestic processing loquat inspissated juice.Common Loquat-Shaped Cake per ton just has 200 kilograms of pomaces to abandon, not only waste but also contaminated environment.
The Loquat-Shaped Cake is through stoning, and juice is removed in the pulp squeezing, still contains carbohydrate in the remaining loquat pomace, the nutriments such as protein and fat, vitamin, and be rich in a large amount of dietary fibers.As long as through conditioning processing, the nutritional labeling in the pomace and dietary fiber just can utilize for the people.
Summary of the invention
The object of the present invention is to provide a kind of loquat dietary fiber vegetables and fruits sheet and preparation method thereof, selecting and producing the pomace of leaving over behind the loquat inspissated juice is primary raw material, be equipped with the nutrients such as calcium gluconae, ferrous lactate, make have additional calcium, the edible health product of a kind of low in calories, the high dietary-fiber of iron function.
For achieving the above object, the present invention adopts following technical scheme:
Concrete steps comprise: once allotment, secondary allotment, heat treatment, shop dish, freeze drying, pack to get product.
Raw material and percentage by weight: loquat pomace 90%-95%, edible gelatin 0.5%-1%, calcium gluconae 0.01%-0.02%, ferrous lactate 0.01%-0.02%, vitamin C 0.1%-0.2%, water 3%-5%.
Edible gelatin is added in 60 ℃ of-70 ℃ of hot water, the weight ratio of edible gelatin and hot water is 1:20-1:25, being stirred to edible gelatin melts fully, get a seasoning liquid, in a seasoning liquid, add the calcium gluconae that measures, ferrous lactate, vitamin C, add the loquat pomace in the stirring, mix, with the heating material to 85 that mixes ℃-90 ℃, keep 15min-20min, the material after the heating is layered on the freeze-drying dish equably, material thickness is at 4-6mm, carry out vacuum drying 16h-18h after-24 ℃ of IQFs, the material after the freeze drying is packed with the high-barrier plastic packaging bag in 3h-5h.The loquat dietary fiber vegetables and fruits sheet color and luster that makes is buff, little sweet little acid, by high-barrier plastic packaging bag packing, 8 months shelf-lifves; Dietary fiber content: 80%-90%, calcium content: 1ppm-2ppm, iron content: 1ppm-2ppm.
Remarkable advantage of the present invention is: selecting and producing the pomace of leaving over behind the loquat inspissated juice is primary raw material, is equipped with the nutrients such as calcium gluconae, ferrous lactate, make have additional calcium, the edible health product of a kind of low in calories, the high dietary-fiber of iron function.
