Embodiment Construction

[0040] In order to make the present invention easier to understand, the present invention will be further described below in conjunction with specific embodiments.

[0041]1. Preparation of composite biological preservative ice: ① Prepare a composite biological preservative with a concentration of tea polyphenols of 0.5% and a concentration of phytic acid of 0.15%; taking the preparation of 1L as an example, weigh 5g of tea polyphenols and 1.5mL of phytic acid , add water to make up to 1L. ②Add the emulsifier glycerin into the compound biological preservation solution to make the mass concentration 0.1%; that is, 1 g of glycerin is added to the compound biological preservation solution to make up the volume to 1 L, and then ultrasonic cleaning machine is used for 15 minutes, and the ultrasonic frequency is 50 Hz. ③Put the complex biological preservation solution containing glycerin in a stainless steel tray (length*width*height=50cm*30cm*5cm) and store it at -18°C for 8 hours ...

Abstract

The invention discloses a method for refreshing pomfrets by using ice containing a composite biological refreshing agent. The method comprises the following steps of: (1) preparing composite biological refreshing liquid containing tea polyphenol and phytic acid; (2) adding glycerinum into the composite biological refreshing liquid; (3) freezing the composite biological refreshing liquid containing the glycerinum into ice blocks at the temperature of -18 DEG C; (4) cleaning the selected pomfrets with ice water, and draining for 2-3 minutes; (5) crushing the ice blocks containing the composite biological refreshing agent by using an ice crushing machine, and storing layered pomfrets and layered ice in a foam box to realize surrounding of crushed ice for the pomfrets; (6) putting the foam box in a refrigerated cabinet with the temperature of 1-4 DEG C for storage; and (7) supplementing the ice containing the composite biological refreshing agent at proper time during the storage period. Compared with the method for refreshing pomfrets by using common ice, the shelf life of the pomfrets can be prolonged for 9-10 days by using the ice containing the composite biological refreshing agent. The method disclosed by the invention is simple and easy, is obvious in refreshing effect, reduces the waste of the pomfrets to a great extent, is a good method which can replace the common iced storage for refreshing the pomfrets, and has large potential for market application.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping of aquatic products and the technical field of composite biological fresh-keeping, in particular to a method for keeping fresh-keeping pomfret on ice, in particular to a method for keeping fresh-keeping pomfret on ice containing a composite biological preservative. Background technique [0002] Pomfret, also known as anchovy, is an economical edible fish, mostly in the South my country Sea and East China Sea, and less in the Yellow Sea and Bohai Sea. Chilling technology is one of the most widely used and earliest technologies for keeping aquatic products fresh. It can keep the original flavor and nutrition of aquatic products to the greatest extent, and it can be seen everywhere in the process of capturing, storing, transporting and selling aquatic products. However, the preservation effect of chilling technology is related to factors such as the type of aquatic products, the amount of ice u...
