Tilapia Fillets

This research aims to analyze the response of methyl red indicator film sensor label color changes on smart packaging in detecting the freshness of tilapia fillets over a shelf life of 10 hours at room temperature (± 25ºC). This research uses a comparative descriptive method. The parameters observed were pH values, total plate count (TPC) and total volatile base nitrogen (TVBN). The results of this research indicate that the response of the film label consists of several concentrations of methyl red namely control (0%); 0.05%; 0.5% and 1%. The best results from film sensor label response is 0.05% Methyl red concentration in detecting the freshness of tilapia fillets and showed the most rapid response to changing the color of the label at the observation of the 7th hours during storage of 10 hours with 8 times the observation time. The freshness of tilapia fillets has decreased quality with changes in pH that tend to fluctuate ie the pH has decreased and then rose again as the color changes are indicated by the film label from yellow to reddish-orange. Total volatile base nitrogen (TVBN) and total plate count (TPC) during the observation showed a trend towards the same graph results, namely, the longer shelf life will increase the decrease in freshness quality of tilapia fillets with marked decay. Therefore, the freshness level of tilapia fillets can be determined by the smart packaging sensor methyl red indicator label at room temperature storage (± 25ºC).

Humidity-controlled dehydration (HCD) was innovatively applied in this paper to control the growth of microorganisms in fresh wet noodles (FWN). Effects of HCD treatment with different temperatures (40, 60 or 80 °C), relative humidity (RH, 50%, 70% or 90%) and treatment time (5–32 min) on the total plate count (TPC), the shelf-life, and qualities of FWN were investigated. The results showed that HCD reduced the initial microbial load on the fresh noodles and extended the shelf-life up to 14–15 days under refrigeration temperature (10 °C). A 1.39 log10 CFU/g reduction for the initial TPC was achieved after HCD treatment at the temperature of 60 °C and RH of 90%. HCD with higher RH had a more positive influence on quality improvement. The L* values, the apparent stickiness, and the cooking properties of the noodle body were improved by HCD while good sensory and texture quality of noodles were still maintained after the dehydration process.

In this study, the pH, total volatile base nitrogen (TVB-N) amounts, total viable counts (TVC) of microbial flora, and the sensory quality of liquid-smoked tilapia fillets were analyzed under different storage conditions. Lengthy storage caused, the smoked flavor to disappear and juice seeped from the samples. Over time, it was found that the pH of the products decreased and then subsequently increased, whilst the amount of TVB-N showed an overall increasing trend. Under all storage conditions tested, the TVC of microbial flora slowly increased, followed by a sharp increase, and then stabilized. These results showed that vacuum-packed products stored at low temperatures were highly stable; hence this storage method can effectively guarantee the quality of liquid-smoked tilapia fillets and the extension of the shelf life.

The combined effects of organic acids and irradiation on shelf life of pork loins were examined. Fresh pork loins were sprayed with organic acids (lactic, citric, and acetic) at 2%, packaged aerobically, and irradiated with an electron beam at 1, 2, and 3 kGy. During 14 days of storage, total plate count, coliform number, pH, and thiobarbituric acid–reactive substances were measured. Combinations of organic acid and irradiation were more effective in reducing and maintaining low total plate counts and coliform levels during storage than either treatment alone. Higher lipid oxidations were observed in all combination treatments at 1 day of storage than in the irradiation-only group. However, lower lipid oxidations were the result after 14 days of storage when combination treatments were used with irradiations of 2 and 3 kGy. Combined treatments involving lower irradiation doses than those required for irradiation alone could be used to extend the shelf life of pork loins during postirradiation storage without increasing lipid oxidation.
