Abstract

The invention discloses a method for preparing loquat fruit rolls and the prepared loquat fruit rolls. The preparation method comprises the following steps of: cleaning, blanching for peeling, splitting for denucleating, pulping, performing vacuum degassing, blending a colloidal substance, boiling, baking, slicing and rolling, and packaging. The sugar content of the loquat fruit rolls prepared bythe method is 65 to 70 percent and the acid content is 1.65 to 2.40 percent; and the loquat fruit rolls have moderate acidity and sweetness, the flavor of loquat, smooth and fine mouthfeel, high softness and hardness, high quality and certain refreshing and moisturizing effects, are yellow red, and do not stick teeth. Aiming at young people and juvenile and children consumer groups and by using the characteristics of abundant pectin and orange yellow and bright color of the loquat, the loquat is processed into the loquat fruit rolls with rich nutrition and attractive color, so that the loquatprocessed product variety is enriched, and the consumer market is expanded.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a loquat fruit roll and a production method thereof. Background technique [0002] Loquat pulp is soft and juicy, moderately sweet and sour, and has a good flavor. It has high medicinal and health effects. It is one of the rare fruits in southern my country. However, due to concentrated listing and perishable deterioration, it is difficult to store and keep fresh, resulting in greater waste and economic loss.
