Freeze-dried lemon slices and making method thereof

Abstract

The invention provides freeze-dried lemon slices and a making method thereof. The freeze-dried lemon slices comprise lemon slices and coating substances coating the surfaces of the lemon slices, and are obtained through coating the coating substances onto the surfaces of fresh lemon slices and performing vacuum freeze drying, wherein the coating substances comprise the following components in parts by weight of 3-5 parts of beta-cyclodextrin, 1-2 parts of stevioside, 5-8 parts of soluble starch and 20-35 parts of water. In the drinking process of the freeze-dried lemon slices, a sweetening agent and citric acid are released together in proportion, so that the sweet-sour proportion can be maintained in a certain range for a long term, besides, destruction and damage of the lemon slices in the transportation process can be avoided to the maximum extent, and the freeze-dried lemon slices can still maintain good appearance state in the process of room temperature storage.

Description

technical field [0001] The invention relates to the technical field of lemon slices, in particular to a freeze-dried lemon slice and a preparation method thereof. Background technique [0002] Lemons are rich in citric acid, vitamin C and other nutrients that are beneficial to the human body. Long-term consumption can clear away heat and cool blood, lower blood pressure and blood lipids, improve blood circulation, regulate physiological functions and prevent aging. The research and development of lemon processed products has promoted the development of lemon industry. [0003] Most of the lemon slices currently on the market are hot-air-dried lemon slices, which are characterized in that the water in the lemon itself is removed by hot-air drying during processing, but at the same time a large amount of nutrients are lost, especially the lemon slices themselves will turn black. , deformation, taste difference and other issues; followed by freeze-dried lemon slices, freeze-dr...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve the problem that the sweetener of the freeze-dried lemon slices and the citric acid in the lemon slices of the prior art are slow-released at the same time and cannot maintain the stability of the mouthfeel and the freeze-dried lemon slices are fragile, so that the freeze-dried lemon slices are packaged, In order to deal with problems such as damage during transportation and affect the appearance and quality of freeze-dried lemon slices, a freeze-dried lemon slice is provided, which releases sweetener and citric acid together in proportion during the drinking process, and can maintain a certain amount for a long time. The sweet-acid ratio within the range; and it can avoid the damage of the lemon slices during transportation to the greatest extent; it can still maintain a good appearance during storage at room temperature
