The invention belongs to the technical field of food 
deep processing and particularly relates to a low 
sugar high 
dietary fiber composite fruit and vegetable paste and a preparation method thereof. 
Fruits and vegetables subjected to sugaring, acidity regulators, thickening agents, coloring matters and essence are subjected to 
scalding treatment, pulping, blending, concentrating, homogenizing, canning and sterilization to form the composite fruit and vegetable paste, the 
mass content of 
soluble solids is in a range from 26% to 31%, and the 
mass content of total 
sugar is in a range from 35.23% to 39.53%. According to the low 
sugar high 
dietary fiber composite fruit and vegetable paste and the preparation method thereof, the 
fruits and vegetables subjected to sugaring are used as main raw materials, the use ratio of the raw materials is improved, the production costs are lowered, types of 
jams are enriched, the preparation method is simple, the operation is simple, convenient and easy to control, the prepared composite fruit and vegetable paste has comprehensive nutritions, low sugar and high 
dietary fiber, health care and edible effects are integrated, the effect of balancing 
human nutrition can be achieved, simultaneously the taste is good, the low sugar high dietary 
fiber composite fruit and vegetable paste has low price and fine quality, the process is simple, the cost is low, the environment is not polluted, and the industrialized production is facilitated.
