Embodiment 1

[0030] A preparation method of freeze-dried candied strawberries, comprising the following steps:

[0031] (1) Picking of raw materials: pick a total of 1,500 kilograms of raw materials with a maturity of more than 8 minutes, no green skin, and no rotten fruit;

[0032] (2) Cleaning: The raw materials obtained in step (1) are selected and graded, and 1480 kilograms of raw materials and impurities that do not meet the requirements such as rot, stain, and insect damage are removed, and the first bubble cleaning machine is used to rinse the fruit. The washing machine has the effect of rinsing and not hurting the fruit;

[0033] (3) disinfection: the raw materials obtained in step (2) are sterilized in batches, each batch is controlled at 150 kilograms, and soaked for 60 seconds with the sodium hypochlorite solution of 250PPM; then rinsed with flowing water for 30 seconds;

[0034] (4) rinsing: the raw material obtained in step (3) is put into the second bubble cleaning machine f...

Abstract

The present invention provides a freeze-dried and sugar-soaked strawberry preparation method. The prepared freeze-dried and sugar-soaked strawberry slices or dices preserve various vitamins of strawberries themselves and unique nutrients of fruits and the preparation method retains original color, smell and taste of the strawberries. The sugar-soaked strawberry technology improves a special strong acid taste of the freeze-dried pure strawberries, which is mainly realized through the following steps: primary quick-freezing and preserving, beating, blending, stirring and putting still, plate laying, quick-freezing, slow-freezing, shape cutting, plate laying, quick-freezing, freeze-drying, semi-finished product inspecting, and finished product packaging. The finished products obtained by the process technology are rich in nutrients. Each 100 grams of the freeze-dried and sugar-soaked strawberries contain 1488 KJ of energy, 5.2 g of proteins, 1.3 g of fats, 77.3 g of carbohydrates, 4.7 g of dietary fibers, less than 5 mg of sodium and 520 mg of vitamin C. The freeze-dried and sugar-soaked strawberry preparation method is easy to operate and remarkable in energy saving effect. The obtained sugar-soaked strawberries are very convenient in consumption, transportation, storage, etc. and easy to promote.

Description

technical field [0001] The invention relates to the field of freeze-dried food production, in particular to a preparation method of freeze-dried candied strawberries. Background technique [0002] Freeze-dried candied strawberries are in a vacuum state, using the principle of sublimation, so that the water in the pre-frozen food is directly sublimated into water vapor in the ice state without being melted by the ice, so that the food is dehydrated and dried. Due to dehydration at low temperature in a vacuum environment, the vitamins and trace elements rich in fruits will not be oxidized, so the color, flavor and taste of the material can be well preserved. The product is crispy in taste and good in rehydration. It does not need to add any additives during processing and preservation. It is a good product for leisure and entertainment, and can also be used as a baby food. convenience and so on. [0003] At present, the production process of freeze-dried candied strawberry s...
