The sensory, microbiological and physicochemical attributes of fresh meat stored at 5 and 15 degrees C were affected by the combined effect of volatile compounds of oregano essential oil and modified atmosphere packaging conditions (40% CO2/30% N2/30% O2, 100% CO2, 80% CO2/20% air, vacuum pack and air). It was found that the extension of shelf life of meat samples depended on the packaging cond...

Many factors influence the shelf-life, color, and sensory attributes of beef. Packaging is one of those factors. There are several different types of packaging used in the meat industry, including vacuum packaging, overwrap, and modified atmosphere packaging (MAP). Traditionally wholesale cuts are vacuum packaged, boxed, and sent to retailers where they cut the meat, place it on a styrofoam tra...

The dose effect of the addition of natural antioxidants (tea, chestnut, grape seed and beer extracts) on physicochemical, microbiological changes and on oxidative stability of dry-cured "chorizo", as well as their effect during the storage under vacuum conditions was evaluated. Color parameters were significantly (p < 0.05) affected by the addition of antioxidants so that samples that contained...

This study was carried out to investigate the effects of three different packing methods including modified atmosphere, vacuum and common packaging on chemical, microbial and sensorial quality and shelf life of hot smoked Rainbow trout (Oncorhynchus mykiss) during storage at refrigerated temperature. For hot smoking, rainbow trout were gutted and cut in butterfly form and washed. Fish gutted br...

INTRODUCTION Meat and processed meats, depending on the animal species and anatomical element from which they were obtained, exhibit a varied fat content (most typically from 10% to 80% dry matter). Fats are relatively unstable food components. The aim of this study was to determine the effect of an addition of model brines on lipid oxidation rate in the selected beef element stored under aerob...

Lipid oxidation, color, volatiles, and sensory evaluation of double-packaged pork loin were determined to establish a modified packaging method that can improve the quality of irradiated pork loins. Vacuum-packaged irradiated samples produced dimethyl sulfide and dimethyl disulfide responsible for irradiation off-odor, whereas lipid oxidation was promoted under aerobic conditions. Exposing doub...

Changes in essential oils (EOs) content and composition of lemon verbena leave at different packaging methods (packaged with air, nitrogen, or under vacuum) and during storage period (0, 2, 4, 6 and 8 months) were determined. All the samples were hydrodistilled every 2 months during storage for EO content evaluation. EO composition was determined by gas chromatography and gas chromatography-mas...

A study was conducted to determine the effects of dietary vitamin E supplementation on the storage stability and volatiles production in irradiated cooked turkey meat. Turkeys, raised with diets containing 25, 50, 75, or 100 IU of dl-alpha-tocopheryl acetate (TA)/kg diet from 1 to 105 d of age, were fed with diets containing 25, 200, 400, or 600 IU of TA/kg diet from 105 to 122 d of age. Breast...

In order to evaluate present and future retail packaging systems, it is necessary to review past fresh red meat (FRM) packaging systems. Prior to 1967, whole beef carcass shipments were traditionally made to retail outlets where carcasses were fabricated into retail items by butchers in individual stores. The "boxed beef" concept was introduced in 1967, dramatically changing beef processing, di...

Proximate analysis, expressible water(EP), water holding capacity (WHC), pH value, total acidity, free fatty acids (FFA), thiobarbituric acid values (TBA), and microbiological examination were determined in order to evaluate the effect of packaging materials and treatments in addition to spice extracts on the shelf life of buffalo meat product stored for nine months under frozen condition. The ...
