Embodiment 1

[0027] Experimental raw materials: fresh mantis shrimp, purchased from the market. Live mantis shrimps with similar body shape, flexible movement and complete limbs were selected as experimental raw materials. The average body weight of mantis shrimps was 13g±2g.

[0028] Experimental supplies: fresh-keeping bags, plastic wrap, polyethylene sample bottles, rubber bands. (The above items are all sterilized by ultraviolet light before use).

[0029] Experimental reagents:

[0030] (1) NaOH (Tianjin Damao Chemical Reagent Factory, analytically pure)

[0031] (2) Concentrated HCl (Quzhou Juzhou Reagent Co., Ltd., analytically pure)

[0032] (3)H 3 BO 3 (Dongguan Dongjiang Chemical Reagent Co., Ltd., analytically pure)

[0033] (4) MgO (Beijing Tongguang Fine Chemical Company, analytically pure)

[0034] (5) Mixed indicator: 2g / L methyl red (Tianjin Benchmark Chemical Reagent Co., Ltd.) + 1g / L methylene blue (Shanghai Sanaisi Reagent Co., Ltd.) (1:1)

[0035] (6) Pure ethan...

Abstract

The invention relates to the field of food storage detection, and discloses a rapid mantis shrimp freshness analysis method under freezing condition. An electronic nose with a plurality of sensor arrays is used in the method, and the sensor arrays include a sulfide sensor, a hydrogen sensor, an ammonia gas sensor, an alcohols sensor, an alkane sensor, a methyl propyl butane sensor, a propyl butane sensor and a nitrogen oxide sensor. The method has the advantages of being capable of rapidly detect a mantis shrimp sample, relatively targeted, accurate and reliable in result, capable of obtaining the detection result without damaging the sample, and strong in applicability.

Description

technical field [0001] The invention relates to the field of food storage detection, in particular to a method for rapidly analyzing the freshness of mantis shrimp under freezing conditions. Background technique [0002] Aquatic products are one of the important components of human food, and are deeply loved by people because of their rich nutrition, delicious taste, and various types. Mantis shrimp is a kind of aquatic product, which is mainly produced in shallow seas in temperate zones. In my country's Bohai Sea, South China Sea and other places, the production of mantis shrimp is relatively large, and it is an important economic fishery resource. Mantis shrimp meat is fresh and tender, with good taste, good taste and high nutritional value. It is not only rich in protein, but also has an ideal amino acid composition. The amount of 8 kinds of essential amino acids contained in it is higher than that of prawn meat. At the same time, the various trace elements rich in manti...
