Low-sugar dried blueberry production technology

The invention relates to the technical field of food processing, in particular to a low-sugar dried blueberry production technology. The technology comprises the steps of S1, performing cleaning and blanching; S2, performing sugar soaking, wherein blanched fresh blueberries obtained in S1 are placed into a sugar solution, and vacuum sugar infusion and normal pressure sugar infusion are performed in sequence to obtain sugar-infused blueberries; S3, performing gluing-off; S4, preparing liquid medicine, wherein by weight, 2-5 parts of astragalus membranaceus, 2-5 parts of medlar, 3-6 parts of mint, 2-4 parts of white atractylodes rhizomes, 3-5 parts of licorice roots and 100 parts of water are taken for warm-fire decoction for 1-2 h, and after filtering is performed, concentration is performed according to the ratio being 50:1 to obtain the liquid medicine; S5, performing drying; S6, performing sterilizing. By adopting the low-sugar processing technology, the safety problem caused by sulfured treatment in a trad
