Preparation process and room-temperature preservation process of loquat pulp

Abstract

The invention discloses a preparation process and a room-temperature preservation process of loquat pulp. The preparation process comprises the following steps: firstly, selecting fresh loquat fruits, washing, removing peels and kernels of the loquat fruits, primarily crushing, and adding a color-preserving reagent; secondly, deactivating enzymatic activity, secondarily crushing, and preserving heat and stirring; thirdly, vacuumizing the stirred loquat pulp; fourthly, preheating the loquat pulp in a sterilizer, and homogenizing the loquat pulp in a homogenizer; fifthly, performing ultrahigh-temperature instantaneous sterilization in the sterilizer, and cooling in the sterilizer after sterilization; finally, performing saturated steam high-temperature filling in a filling machine by using aluminum foil packaging bags, and carrying out sealing, warehousing, and preserving at room temperature, wherein procedures from primary crushing to filling preservation are performed in a sealed environment. The loquat pulp prepared by the preparation process is low in preservation cost; the preparation process is simple, and the loquat pulp can be preserved at room temperature; the procedures after primary crushing are performed in the sealed environment, and the loquat pulp does not contact outside air any longer, so that the loquat pulp cannot be oxidized to cause browning.

Description

technical field [0001] The invention relates to a process for preparing loquat pulp and storing it at room temperature, belonging to the field of food processing and storage. Background technique [0002] Loquat is a kind of fruit that is very popular and often eaten by the public. The beverage with loquat pulp as the main ingredient is orange in color. In addition to the functions of general beverages, it also has the functions of moistening the lungs and clearing away heat. The nutrients contained in the edible part of loquat fruit include protein, fat, carbohydrates, calcium, iron, gamma vitamins, carotenoids, etc. Among them, calcium, phosphorus and carotene are significantly higher than other common fruits, and contain essential nutrients for the human body. of 8 amino acids. [0003] Since the shelf life of fresh loquat fruit is not long, if it is preserved by freezing, Xiaoxu loquat fruit needs to be thawed before each processing, and then made into pulp. Such a cumb...

Problems solved by technology

[0005] Existing methods for the preservation of loquat pulp have many deficiencies: the pulp is oxidized and browned in contact with the outside air, which directly affects the color and quality of the product, and is not conducive to preservation; the processing process is complicated, the cost is high, and the efficiency is low; the added food Additives contain excessive toxic and harmful ingredients to the human body, destroying the nutritional ingredients in the pulp; during the production process, the discoloration and deterioration of the pulp cannot be effectively suppressed
