Embodiment 1

[0013] Fruit picking: From August to October, pick fresh yellow and ripe Rosa roxburghii fruits that are free from diseases and insect pests, rinse with clean water, remove impurities, put them in baskets and drain;

[0014] Fengruan: Weigh 100g of the drained fresh Rosa roxburghii fruit, spread it out on the wire mesh rack in the drying room, and air-dry it at room temperature until the fruit is soft, and the water content of the fruit is 55% and taken out.

[0015] Seed removal: remove the calyx with a stainless steel knife, and cut the fruit from here to the fruit pedicle, do not completely cut and separate, open it with a stainless steel scissors, and remove the bony achenes;

[0016] Air-drying: Immediately send it to the wire rack in the drying room, use medium-temperature hot air at 60°C until the fruit is half-dried, and the water content of the fruit is 35%;

[0017] Air-drying: Use low-temperature hot air at 38°C again, and cool down to room temperature when the wate...

Abstract

The invention relates to a method for making dried roxburgh rose fruit. In the fabrication method, aiming at the defects of the existing roxburgh rose sun-drying and drying processing method such as oxidation of vitamin C under ultraviolet rays, great loss of nutrients and human health hazards caused by later-stage sulphur powder fumigation, a three-segment air-drying mode is adopted so that the fruit product is dried from inside to outside, the high temperature time is shortened, the probability of oxidation reaction is reduced, the greatest nutrient quantity of the fruit product is maintained, the problems such as cracked surface, poor appearance and high humidity in the fruit during the high-temperature sun-drying process are avoided, the sulphur fumigation procedure is not required, and the loss of the vitamin C is reduced to 3.2%-4.8% during the preservation period, thus solving the problems such as difficulty in preservation and nutrition loss.

Description

technical field [0001] The invention relates to deep processing of fruit, in particular to a method for making dried roxburghii. Background technique [0002] The current processing of dried roxburghii is to dry and dry the fruit, because sunlight and ultraviolet rays have oxidative defects on the vitamin C contained in the roxburghii fruit; direct drying, the loss of nutrients caused by high temperature, and the prior art The dried prickly pears made are smoked with 2 kg of sulfur powder per ton of dry product for 2 hours before storage, then packed in sacks and stored in film bags with a coat. After 1 year, vitamin C only loses 2.85%. If it is not treated with sulfur fumigation, the loss of vitamin C will be as high as 80% after one year. Sulfur is a kind of chemical raw material. Sulfur combustion can bleach and keep fresh, making the color of items appear white and bright. But it is very harmful. For example, ① the residual sulfur in the sulfur smoking process will gene...
