Problems solved by technology

The main deficiency of the above invention is that the skin layer of pomelo peel is much denser than the sponge layer, and its ability to absorb the penetrating fluid is low, causing the skin layer and the sponge layer to absorb components in the penetrating fluid unevenly, and the skin layer of the finished product Easy to shrink
For debittering, soy milk is used to cover the bitterness of pomelo peel, which will cause aftertaste in the mouth when eaten; microwave, hardening, and β-cyclodextrin embedding debittering process is more complicated

Abstract

The invention discloses a shaddock ped preserved fruit and a preparation method thereof. Fresh shaddock ped is adopted, the outer layer of the fresh shaddock ped is punctured, the fresh shaddock ped is immersed into water to be de-bitterized by virtue of ultrasonic wave, then the fresh shaddock ped is immersed into mixed solution of lower-concentration sugar and edible gum to be subjected to vacuum penetration, and then air pressurizing penetration is carried out, and finally drying, packaging and surface sterilizing are carried out, thus low-sugar shaddock ped preserved fruit finished product is obtained. The invention has the advantages of fast debitterizing speed, uniform penetration, full product appearance, low sugar content, good taste and the like.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a preserved pomelo peel and a preparation method thereof. Background technique [0002] Preserved fruit is a traditional food in my country and is liked by consumers in general. However, traditional preserved fruit has a high sugar content, generally greater than 55%, and the product has a high calorific value. Long-term consumption can easily cause obesity. Low-sugar preserved fruit has become an important direction for the development of the preserved fruit industry. Pomelo is the mature fruit of pomelo, a plant of Rutaceae, which is produced in southern my country such as Fujian, Jiangxi, Guangdong, and Guangxi. The volatile oil in pomelo peel is mainly citric acid and aromatic alcohol, which has the effect of warming the stomach, reducing phlegm, and moisturizing the throat; pomelo peel also contains flavonoids such as naringin and rutin, which have antioxidant eff...
