The invention discloses a 
processing method for low-
sugar preserved ginger, and relates to the technical field of preserved fruit 
processing. The 
processing method for the low-
sugar preserved ginger comprises the following steps: 
slicing fresh gingers; soaking ginger slices with brine containing 8% of 
citric acid, then adding edible salt which accounts for 2-3% of the total 
mass of the brine and the ginger slices, soaking, then adding 1-2% of edible salt, soaking, adding 1-2% of edible salt, naturally fermenting, and taking out the ginger slices; 
scalding the ginger slices in boiling water, taking out the ginger slices and then draining water from the ginger slices; placing saccharose which accounts for 60-70% of the initial 
mass of the ginger slices in the ginger slices, blending uniformly and carrying out sugaring; adding 
sodium alginate which accounts for 0.1-0.3% of the initial 
mass of the ginger slices and 
carrageenan which accounts for 0.05-0.1% of the initial mass of the gingerslices in the sugared ginger slices, cooking with 
sugar, and then taking out the ginger slices; and heating and baking the sugar slices until the 
water content reaches 35-45%, and then 
drying under vacuum until the 
water content reaches 25-30%. The processed preserved ginger is brilliant yellow, is good in glossiness, has full appearance, is full in sugaring, and has uniform 
sweetness, the insideof the preserved ginger has weak spicy taste, the sugar content is low, the quality is good, and the health value is high.
