| Abstract | ||
| Intelligent food packaging, is new packaging, that in recent decades has been used in developed countries and is designed to show safety, quality and product security. Given the importance of fishery products at the household food basket, on the other hand, this product is made of quick-corruption to the color indicators on the packaging fillet of rainbow trout used during refrigerator storage. in this research, treatments includes common packaging with phenol red indicator and common packaging with bromocresol green indicator, Indicators made of colored reagent phenol red and bromocresol green in matrix low-density polyethylene film were used in bags made of low-density polyethylene was produced in the country. For the determine quality were used of the microbial tests (total count bacteria, psychotropic bacteria) and chemical (pH, TVN, TBRSA) at the time of changing the color indicators and also on days zero, 5, 10, 15 and 20 are kept at refrigerator temperature CË (4±2). Based on the results of the color change indicators and its relationship with chemical and microbial tests have been done by SPSS 18 statistical software. Shelf-life rainbow trout fillet for the treatments of common packaging with phenol red indicator and common packaging with bromocresol green indicator was determined at refrigerator temperature 13 to 14 days. | ||
