Description

TECHNICAL FIELD

[0002] The freshly picked Zhigan Junju jujube does not achieve the best sensory quality, such as high water content and low total sugar content. The current technology generally uses constant temperature drying Zhigan Junju jujube. Although this method is simple, long-term high temperature can easily cause the quality of Zhigan Junju jujube to deteriorate, resulting in browning and souring of the fruit pulp. How to further process Zhigan Junju jujube to improve its sensory quality and meet the current demand for higher quality Zhigan Junju jujube food requires further research.

[0003] In order to solve the above technical problems, the present Chinese patent with publication number CN112205461A discloses a temperature change drying method for Zhigan Junju jujube, which includes the following steps: the first stage drying lasts for 90-110 min, and the temperature is 60-70℃; the second stage drying lasts for 190-210 min, and the temperature is reduced by 5-10℃ every 30 min until it reaches 40-50℃; the third stage drying lasts for 45-75 min, and the temperature is reduced by 3-7℃ every 15 min until it reaches 25-30℃, and the drying is completed. The present application selects a higher temperature in the early stage of drying to obtain the fastest drying rate, and selects a lower temperature in the later stage to reduce the negative effects of high temperature on the raw materials. By combining high temperature with low temperature, a higher drying rate is obtained while the original quality is preserved to the greatest extent. This method is suitable for continuous production, reduces energy consumption, and avoids tissue shrinkage caused by rapid cooling. Compared with traditional constant temperature drying, the Zhigan Junju jujube dried by the present application has a high sugar-acid ratio, low internal browning, and stable quality. The fruit is fully saccharified while maintaining its original quality.

[0004] The above technical solution uses a temperature change method for drying, but it cannot effectively control the size of Zhigan Junju jujube and cannot quickly produce an integrated product, which affects the efficiency of drying. Therefore, it needs to be improved. SUMMARY
