Prediction of egg freshness during storage using electronic nose
The aim of the present study was to investigate the potential of a fast gas chromatography (GC) e-nose for freshness discrimination and for prediction of storage time as well as sensory and internal quality changes during storage of hen eggs. All samples were obtained from the same egg production farm and stored at 20 °C for 20 d. Egg sampling was conducted every 0, 3, 6, 9, 12, 16, and 20 d. D...
متن کاملNon-destructive egg freshness determination: an electronic nose based approach
An electronic nose (EN) based system, which employs an array of four inexpensive commercial tin-oxide odour sensors, has been used to analyse the state of freshness of eggs. Measurements were taken from the headspace of four sets of eggs over a period of 20–40 days, two ‘types of egg data’ being gathered using our EN; one type of ‘data’ related to eggs without a hole in the shells and the other...
متن کاملDiscrimination and Prediction of Pork Freshness by E-nose
An electronic nose (e-nose) was used to establish a freshness evaluation model for pork. A pre-experiment was performed to acquire optimum parameters (10 g sample mass with 5 min headspace-generation time in 500 mL vial) for later e-nose detection of pork. Responding signals of the enose were extracted and analyzed. Linear Discriminant Analysis (LDA) results showed that the e-nose could classif...
متن کاملMonitoring the Freshness of Rainbow Trout Using Intelligent PH-sensitive Indicator During Storage
Background: The rainbow trout fish is susceptible to spoilage due to its high content of unsaturated fatty acids. It should be kept at low temperature to reduce microbial, enzymatic, and oxidation reactions. The purpose of this study was to design a packaging that contains a pH indicator for monitoring freshness of the rainbow trout fish during storage at refrigerator. Methods: The indicator co...
متن کاملPoultry meat freshness evaluation using electronic nose technology and ultra-fast gas chromatography
ABSTRACT To ensure that chicken meat products are safe to consume, it is important to be able to reliably determine its shelf-life. To assess the applicability of ultra-fast gas chromatography and electronic nose technology in evaluation of poultry, an analysis of the headspace of ground chicken meat samples refrigerated over a period of 7 days was performed. Chemometric techniques were used to...
