Optimal packaging and storage conditions for fresh tilapia fillets were established by evaluating sensory and microbiological changes, as well as monitoring physicochemical properties. Nile tilapia (Oreochromis niloticus) farmed in recirculation aquaculture system was filleted, deskinned, and packaged in air and 50% CO2/50% N2 prior to chilling and superchilling storage at 1°C and -1°C. Sensory...

This study was performed to improve the techniques used for tenderizing red meat as elderly food. Beef meat was immersed in liposome encapsulated enzyme solution and the effect of protease encapsulation on the beef properties was analyzed. The protease encapsulation properties were analyzed according to the size distribution and enzymatic activity. After enzyme reaction on the beef, the chemica...

Han F., Huang X., Teye E., Gu H., Dai H., Yao L. (2014): A nondestructive method for fish freshness determination with electronic tongue combined with linear and non-linear multivariate algorithms. Czech J. Food Sci., 32: 532–537. Electronic tongue coupled with linear and non-linear multivariate algorithms was attempted to address the drawbacks of fish freshness detection. Parabramis pekinensis...

An intelligent pH-sensing indicator containing Roselle (Hibiseus sabdariffa L.) (RS) anthocyanin and curcumin (CR) was developed characterized as on-package tags to check the freshness of shrimp during storage at 4°C. FE-SEM FT-IR analysis showed that RS CR were successfully immobilized in gelatin–glycerol film-forming substrate. The addition various natural dyes increased thickness antioxidant...

The aim of the work was to analyze effect storage in freezing conditions (-18 ° C) during 3 months on formation malondialdehyde MDA, TVB-N (total volatile basic nitrogen), and colour. Rainbow trout up 500 g (RT) aged 1-1.5 years (n=15) (RT1) 3.5 kg 2-2.5 were included experiment. stated weight fish is already after processing. After slaughtering fish, samples taken from each for analysis meat c...

Summary This study was conducted to evaluate the effect of chitosan coating enriched with garlic extract (GE) and coriander essential oil (CEO) on shelf life rainbow trout fillet. Treatments were prepared (2%) containing GE CEO (0.1% 0.5%) both separately in combination. The results showed that had significant effects peroxide value (PV), thiobarbituric acid (TBA), total volatile basic nitrogen...

This study was carried out to evaluate the effects of various kinds of salt on the quality and storage characteristics of tteokgalbi. The tteokgalbi was prepared using four types of salt: 1.5% purified salt (control, C), 1.5% five-year-old solar salt (FS), 1.5% Topan solar salt (TS), and 1.5% French Guérande solar salt (GS). The moisture, crude lipid, crude ash, crude protein and calorie conten...

plants have noticeable effects on soil resources distribution and its biochemical processes, and organic materials are naturally much more in the understory soil as compared to open areas. vegetation as one of the soil formation factors is not always an independent variable, so that the soil and vegetation can have interaction. the present study was conducted to investigate the effects of hedys...

In this research, the effect of different parameters of coal composition (coal chemical properties) were studied, to estimate the coal HGI values index. To estimate the HGI values artificial neural networks (ANNs) and linear multivariable regression methods were used for 400 data. In this work, ten input parameters, such as moisture, volatile matter (dry), fixed carbon (dry), ash (dry), total s...
