Abstract

The invention relates to a processing method and a processing device of dried dragon fruit slices. The processing method comprises the following steps: (A) cleaning dragon fruit, cutting off the two ends of the dragon fruit, and cutting the dragon fruit into slices with the thicknesses of 4-6mm along the transverse direction, or removing the peel and cutting the dragon fruit into slices with the thicknesses of 4-6mm along the transverse direction to obtain the fruit slices; (B) rapidly soaking the fruit slices into a color fixative for 30-60 minutes, then cleaning the fruit slices with clear water to remove the color fixative from the surfaces of the fruit slices, wherein the color fixative comprises the following components by weight percent: 0.5-1.0% of ascorbic acid, 0.5-1.0% of citric acid, 0.4-0.8% of table salt and the balance of water; (C) drying the fruit slices processed in the step (B) at the temperature of 50-60 DEG C until the water content of the fruit slices is 16-28%; (D) ironing the two sides of the dried fruit slices for 5-20 seconds at the temperature of 100-110 DEG C to obtain the dried dragon fruit slices. The dried dragon fruit slices prepared by the method have the strong characteristic aroma of the dragon fruit and the seeds of the dragon fruit emit unique fragrance of sesame.

Description

technical field [0001] The invention relates to the processing of fruits, in particular to a processing method of dried pitaya fruit slices. Background technique [0002] Dragon fruit is the fruit of the cultivars of the genus Trigonum (or Hylocereus undatus) of the family Cactaceae (Cactaceae), which originated in Central America and is widely distributed in Vietnam and Thailand. my country is mainly distributed in Taiwan. , Guangdong, Guangxi, Yunnan, Guizhou, Fujian and other places, the common varieties include red skin and white meat, red skin and red meat, and yellow skin and white meat. The nutritional value of dragon fruit is very rich. The anthocyanins it is rich in have the effects of anti-oxidation, anti-free radicals, and anti-aging. It is also rich in water-soluble dietary fiber, which has the effects of losing weight, lowering blood sugar and moisturizing the intestines. The seeds of dragon fruit contain unsaturated fatty acids and antioxidant substances, which...
