Embodiment Construction

[0021] Below in conjunction with embodiment, the present invention will be further described:

[0022] Experimental equipment: FW-200 strong acidic electrolyzed water generator (AMANO, Japan), ultra-clean bench (ESCO WORLD CLASS WORLDWIDE), pH / ORP tester (Mettler Toledo Instruments Shanghai Co., Ltd.), RC~3F High-concentration available chlorine tester, BagMixer400VW flapping homogenizer (French interscience company), QL~901 vortex oscillator (Jiangsu Haimen Qilinbeier Instrument Manufacturing Co., Ltd.), water-proof constant temperature incubator.

[0023] Example:

[0024] (1) Preparation of acidic electrolyzed water: Dissolve 2g of sodium chloride in 2L of deionized water, and then place the aqueous sodium chloride solution in a FW-200 strong acidic electrolyzed water generator. Under the operating conditions of A, after 13 minutes of electrolysis, collect strongly acidic electrolyzed water in the anode area; under the condition that the above electrolysis equipment and wo...

Abstract

The invention belongs to the field of food fresh keeping, and particularly relates to a fresh-keeping method for penaeus vannamei by acidic electrolyzed water ice. The method comprises the following steps of firstly, using a sodium chloride solution as an electrolyte, and electrolyzing to prepare acidic electrolyzed water; then, freezing the prepared acidic electrolyzed water to obtain the acidic electrolyzed water ice, and crushing the acidic electrolyzed water ice for standby; and finally, flatly putting the penaeus vannamei on the crushed acidic electrolyzed water ice. The mass concentration of the sodium chloride solution is 0.1% to 0.5%, the voltage is 100V, the current is 0.5A, and the electrolyzing time is 10 to 20 minutes. Because the acidic electrolyzed water ice has low temperature, low pH (potential of hydrogen) value and certain content of effective chlorine concentration, the growth of the exogenous microbes on the surface of the penaeus vannamei is effectively decreased, the fresh-keeping time of the penaeus vannamei is prolonged, the organoleptic effects on the color, odor, muscle and the like of the penaeus vannamei are reduced, and the blackening speed of the penaeus vannamei head is decelerated; the acidic electrolyzed water is used after being sealed and frozen, the loss of effective chlorine concentration in the electrolysis is little, and the fresh-keeping effect is good.

Description

technical field [0001] The invention relates to the field of food preservation, in particular to a method for preserving the freshness of Penaeus vannamei by using acidic electrolytic water ice. Background technique [0002] Penaeus vannamei grows fast, has strong disease resistance, delicious meat, a wide range of suitable temperature and salt, and a processed meat rate of 67%. It is an excellent freshwater cultured species and has become one of the three major cultured prawns in my country. At present, my country's Guangdong, Guangxi, Fujian, Hainan, Zhejiang, Shandong, Hebei and other provinces or autonomous regions have gradually promoted breeding. [0003] Although Penaeus vannamei is delicious, nutritious and of high economic value, compared with some other aquatic products, it is very easy to spoil and deteriorate. Shrimp usually dies soon after fishing. The enzyme activity of the head of the shrimp is very strong. Many, because vannamei shrimp meat has high water co...
