Embodiment 1

[0019] Embodiment 1: the frozen processing method of the whitebait of the embodiment of the present invention comprises the following steps:

[0020] 1. Choose fresh whitebait with complete fish body, plump flesh, transparent eyeball cornea, clear and shiny body surface, and white or blue-white translucent state.

[0021] 2 Rinse the qualified raw fish into a mixed solution of sodium polyphosphate and sodium pyrophosphate to remove impurities. The concentration of the solution is 3%, and add ice cubes to keep the water temperature at 5°C. Ice and weeds, and sort out other fish and shrimp. After rinsing, fish body sizes of 3-5 cm, 6-8 cm, 9-12 cm, and 13-15 cm are stored in different flat baskets for processing.

[0022] 3 Put the rinsed whitebait into a container with a leaking hole at the bottom, drain for 10 minutes, and keep the room temperature at 10°C.

[0023] 4 The drained whitebait is weighed and bagged according to different specifications. When weighing, add an ap...

Abstract

The invention discloses a freezing processing method of whitebait. The method comprises the following steps: selecting high-quality fresh whitebait; rinsing the raw material whitebait to remove impurities, and classifying and containing the whitebait according to the length; draining the rinsed whitebait in a container with the bottom provided with water leakage holes; weighing and bagging the drained whitebait according to different specifications; regularly arranging the whitebait, and sequentially putting the whitebait in freezing discs in a face-down manner; boxing the freezing discs, immediately sending obtained boxes into a cold store with the temperature of -25 DEG C or below, and freezing the whitebait; and packaging the frozen whitebait, and refrigerating the packaged whitebait in a -18 DEG C cold store. Compared with the prior art, the method disclosed in the invention has the following advantages: the high-quality raw material whitebait are selected and are classified and contained according to the length, and different freezing times are set according to the different size, so the processing efficiency is improved; the water temperature and the room temperature environment in the whole processing process are low, so deterioration of the whitebait in the processing process is effectively prevented, and high-quality whitebait with the advantages of freshness, normal color, no peculiar smell, complete body form and realization of the weight of unfrozen white bait being not lower than a prescribed weight are finally obtained.

Description

technical field [0001] The invention relates to a freezing processing method for whitebait, belonging to the technical field of food processing. Background technique [0002] Whitebait (English: salangid) is a freshwater fish found in saltwater and freshwater in East Asia, and is known as a delicacy in China.
