Method for producing low-sugar and low-heat value golden thread preserved date

The invention relates to a manufacturing method for golden thread preserved dates with low carbohydrate and lower calorific value, which comprises the steps of the screening, the cleaning, the filum dividing, the scalding and bleaching, the saccharifying and soakage, the baking and the reshaping of Chinese date fruit and the packaging of finished products; and is characterized in that: ethroglucin is used for replacing part of saccharose in the saccharifying or soakage process for manufacturing the Chinese date fruit. Being determined by tests, the sugar content of the golden thread preserved dates produced by the method of the invention is reduced from 70 percent or so which is originally processed by adopting the traditional technology to 20 to 30 percent, and the original flavor and sweet taste of the golden thread preserved dates are not affected; furthermore, as the permeation pressure of the ethroglucin is high, sugar-permeating time is greatly reduced, process is simplified and cost is reduced; in addition, the ethroglucin does not have the Maillard reaction of reducing sugar, therefore, in the process of saccharigying, the color change of the Chinese dates is small, and the products have light color and luster and better condition.
