两种多金属氧酸盐对冷藏南美白对虾保鲜效果的研究
Study on the Preservative Effects of Two Types of Polyoxometalates on Refrigerated Litopenaeus vannamei
摘要
Abstract
To investigate the preservative effects of transition metal-substituted Dawson-type phosphomolybdic acid on Litopenaeus vannamei(Pacific white shrimp)under refrigerated storage at 4℃,5 mmol/L cobalt-substituted phos-phomolybdic acid(P2Mo17Co)and zinc-substituted phosphomolybdic acid(P2Mo17Zn)were used as treatment agents,with a blank control group established.The quality changes of the shrimp under refrigerated storage at 4℃were ana-lyzed through indicators including sensory evaluation,melanosis score,total colour difference(ΔE),drip loss rate,total volatile basic nitrogen(TVB-N)value,and total viable count(TVC).The results showed that although both treatment agents caused a slightly higher drip loss rate than the control group on day 10,they significantly delayed the quality de-terioration of shrimp.On day 6,the sensory scores of the P2Mo17Co and P2Mo17Zn treatment groups reached 6.56 and 6.58 points,respectively,significantly higher than the 4.28 points of the control group.On day 10,the ΔE value,melano-sis score,pH increase,TVB-N value,and TVC of both treatment groups were significantly lower than those of the control group.Specifically,TVB-N was reduced by 31.2%-38.8%and TVC was reduced by 17.6%-23.4%compared with the control group.Overall,P2Mo17Co and P2Mo17Zn could extend the shelf life of refrigerated L.vannamei by 2-6 days,with P2Mo17Co showing superior performance in inhibiting TVB-N accumulation and microbial proliferation.This study con-firmed the potential of transition metal-substituted Dawson-type phosphomolybdic acid for aquatic products preservation.关键词
