Problems solved by technology

Although there are currently reports on dragon fruit series products, most of the research is to explore its processing technology, and its products are still in the research stage, the applicability is not strong, and there are few actually put into large-scale industrial production
Pitaya is not resistant to storage. At present, the main storage method of pitaya is low-temperature refrigeration, but the storage effect is not ideal, and the fresh-keeping period is very short (2-3 weeks). The annual loss rate of pitaya is as high as 20-25% in China
[0005] Under the condition of backward fresh-keeping technology, only fresh fruit sales restrict the cultivation and development of dragon fruit

Abstract

The invention discloses a production method of red dragon fruit vinegar. The production method comprises the following steps: pulping red dragon fruits; controlling the viscosity value of dragon fruit juice at 100 to 140mpa.s; adding pectinase in an amount of 0.4 to 0.6 percent based on the volume of the juice; stirring uniformly; stirring at the temperature of 47 to 52 DEG C for enzymolysis for 2.5 to 3 hours; adjusting the sugar degree of the juice to 20 to 25 degrees BX; sterilizing; inoculating yeast: after the juice is cooled to 40+ / -2 DEG C, filtering the juice by a 80-mesh screen and adding 0.02 to 0.04 percent brewer's yeast; activating and stirring uniformly; fermenting at the room temperature till the alcohol by volume of the juice is more than or equal to 16+ / -1 percent; ageing the fruit wine; activating an acetic acid strain; performing fruit vinegar fermentation, ageing, blending, sterilizing and hot filling. The fruit vinegar product has the advantages of high quality, safety for eating, pure taste and short production period.

Description

technical field [0001] The invention belongs to the field of food biotechnology, and in particular relates to a production method of red dragon fruit vinegar. Background technique [0002] Pitaya, also known as red dragon fruit, fairy fruit, lover fruit, etc., belongs to the Cactaceae (Cactaceae) triangular column (Hylocereus) and Xishi fairy column (Selenicereus) plants, of which the red dragon fruit (Pitaya) is a triangular column . There are three types of dragon fruit: red-skinned and white-fleshed (Hylocereus undatus), red-skinned and red-fleshed (Hyhcerms polyrhizus) and yellow-skinned and white-fleshed (Hylocereus). Dragon fruit is a high-fiber, low-sugar, low-fat "one high and two low" green health food. It is rich in vitamins, calcium, magnesium, phosphorus, iron and other minerals, and contains plant-based albumin, which is rare in ordinary plants. And anthocyanins, rich in vitamins and water-soluble dietary fiber. Red meat dragon fruit contains a relatively com...
