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...

Aim of this study was to investigate influence the shelf life and quality characteristics fried chicken with various levels shrimp powder (0%, 5%, 10%, 15%). Fried in soybean oil heated 170°C stored at 4°C for 3 weeks refrigerator. Quality determined by analyzing color, pH, sensory properties, thiobarbituric acid reactive substance (TBARS), volatile basic nitrogen (VBN), total plate counts (TPC...

In this study, we evaluated the effects of immersion freezing (IF) with coolant and air (AF) techniques different storage temperature (?18°C ?30°C) on quality groupers following frozen storage. Water loss rate, total volatile basic nitrogen, K-value, were positively correlated time. The pH first decreased then increased. Destruction muscle fiber structure led to changes in grouper texture chara...

This study investigated the antioxidative and functional effects of a curing agent containing grapefruit seed extract (GSE) on the quality and storage characteristics of chicken breast. The total polyphenol and total flavonoid contents of GSE were 45.06 mg/g and 36.06 mg/g, respectively. The IC50 value of 2,2-diphenyl-1-picrylhydrazyl hydroxyl scavenging of GSE was 333.33 μg/mL. The chicken bre...

This study was aimed to determine the changes of the local anchovy meal which is known as hamsi kaygana in Turkey during cold storage at +4°C ± 1°C. Physicochemical (pH, TVB-N, TMA-N, and TBA) shelf life analyses were carried out for hamsi kaygana samples. It was confirmed that the pH values obtained from research groups were within the limit values of the literature. No statistically significa...

In this study, the performance of two aerobic sequencing batch reactors (SBR) in removing carbon and nutrient (N & P) from Faraman’s industrial estate wastewater (FIW) with flocculated and granulated sludge were compared. The comparison study was performed by varying two significant independent variables (aeration time and mixed liquor volatile suspended solids (MLVSS)). The experiments were co...

 Cypermethrin is a potential toxic pollutant that directly threatens the aquatic ecosystems and environment. Propolis, a natural product collected from plants by honey bees has many functions, such as antimicrobial, antioxidant, and anti-inflammatory. This study attempted to detrmine some biochemical and microbiological parameters of rainbow trout fillets after exposure to propolis an...

Atlantic horse mackerel (Trachurus trachurus) fillets were coated by gallic acid and chitosan solutions, including nanoparticles, fish quality shelf life assessed during chilled storage for 13 days. All chitosan-containing coatings decreased microorganisms’ growth in more than 2 log cycles up to late stages; however, those with nanoparticles resulted be effective, probably due a greater contact...

The purpose of the study was to compare basic fruit chemical composition of four highbush blueberry cultivars: ‘Spartan’, ‘Bluecrop’, ‘Jersey’ and ‘Blueray’. The plants were grown on plantation near Szczecin in the years 2001 – 2003. Basic chemical composition of fruit including total ash, crude fibre, total nitrogen, soluble solids, titratable acidity, dry weight and total polyphenol content w...
