Research Of Instant Jellyfish Standard And The Predictive Of The Shelf-life

As aquatic biological resources,Instant jellyfish were more susceptible to bacteria,viruses,and biological toxins in water,heavy metals,pesticides,organic pollutants such as pollution,and then through the food chain caused harm to the health and safety of consumers.And instant jellyfish as a ready-to-use product,prone to quality problems such as insufficient solids content exceeds bid,aluminum residue.In addition,high temperature would destroy the collagen structure of jellyfish,affected the taste,so in the instant jellyfish usually adopt uv in the production process of sterilization,instead of using high temperature for sterilization,this would inevitably lead to microbial residues,microorganisms in the process of transportation,sales growth,eventually led to the microorganism.Therefore,the purpose of regulating the production of instant jellyfish,promotd the sustainable development of the aquatic products processing industry in liaoning,urgently to instant jellyfish local standards in liaoning province.In order to understand the quality of instant jellyfish products produced in Liaoning province,in this study,the investigated data obtained from the jellyfish products were analyzed,which could provide a significant information for establishing a local standard of instant jellyfish including sensory index,physical and chemical index and microbial indicators.The results revealed that the deficiencies of solids content,the excess of the residue of aluminum and microbial overweight were existed in the individual instant jellyfish products.Among these standards examed,solid content was lower than 50 g / 100 g in 32 samples of 59 samples;meanwhile,the residue of aluminum over the standard was discovered in 6 samples,and the proportion was 10.2 %;total viable count within more than 6 Log CFU/g was detected in 6 samples of 59 samples(10.2 %).In addition.Because the phenomenon of quality degradation was existed in instant jellyfish during the shelf life,setting up a reasonable shelf life for instant jellyfish products was necessary.The materials were analyzed quality and the safety and a prediction model of shelf life was established.According to this model,shelf life of instant jellyfish in the production process could be estimated under the known storage temperature and TVB-N content.
