Abstract

The invention relates to strawberry-carrot composite jam and a preparation method thereof and belongs to the technical field of food production. The strawberry-carrot composite jam comprises 30-45 parts of strawberries, 15-30 parts of carrots, 10-15 parts of white sugar, 0.1-0.5 parts of citric acid, 0.1-0.5 parts of isoascorbic acid, 0.1-0.5 parts of a curing agent and 0.15-0.3 parts of a thickening agent. The preparation method comprises selecting full ripe strawberries, cleaning the strawberries, carrying out pulping, selecting compact orange-red carrots with small center pillars, cleaning the carrots, beating the carrots through a tissue stamping machine to obtain slurry, mixing the carrot slurry and the strawberry slurry, carrying out stirring to obtain a uniform mixture, adding granulated sugar into the mixture according to a proper ratio, adjusting pH of the mixture to about 3.5 through citric acid, carrying out vacuum concentration at a temperature of 70-80 DEG C under pressure of 0.6MPa for 20-25min, adding the thickening agent, the curing agent and sodium isoascorbate into the mixture, carrying out concentration under normal pressure until a terminal point, carrying out loading in a pot at a temperature of 85 DEG C, sealing the pot, carrying out sterilization in boiling water for 20min, taking out the mixture, carrying out stepped cooling, carrying out thermal insulation at a temperature of 38 DEG C for 7 days to obtain a non-swelling finished product and carrying out packaging. The strawberry-carrot composite jam is rich in nutrients and has good color, smell and taste.

Description

technical field [0001] The invention relates to a strawberry and carrot compound jam and a preparation method thereof, belonging to the technical field of food production. Background technique [0002] China's fruit planting area continues to expand, output has increased year after year, but prices have continued to fall, especially the special fruits in the Pearl River Delta, such as lychee and longan, have also lost their price advantages and dropped to the lowest level in history. This shows that the development of deep processing of fruits is on the way. It must be done. The development of jam is one of the only ways. The fruit jam is made of fresh fruit as the main material, which is deeply processed by high-tech technology formulas such as peeling, denuclearization, color protection, sterilization, and flavor preservation, so that the jam maintains the unique characteristics of fresh fruit. Natural flavor, and after various collocations and adjustments, it has sweet an...
