ABSTRACT The drying of sea bass was examined using oven and infrared (IR) at 60–80°C, and microwave (MW) at 140–350W. Effective moisture diffusivities and activation energies were determined, and mathematical models were applied to the data. Moisture content was found as 1.8571 kg water/kg dry matter and reduced to 0.1009–0.0798, 0.0767–0.0520, and 0.0783–0.066 kg water/kg dry matter for oven, IR, and MW, respectively. Drying times were found as 300–180, 315–135, and 18–5 for oven, IR, and MW, respectively. The most compatible models found as Midilli and Kucuk for oven, Aghbashlo et al. for IR, and Alibas for MW.

ABSTRACT R-phycoerythrin (R-PE) is a red pigment present in algae with potential application in the biotechnology industry. This study aims the physical-chemical characterization and antioxidant activity of R-phycoerythrin from Gracilaria birdiae (CE-Gb). The spectroscopic stability of the pigment against different additives was also evaluated. The results showed antioxidant activity dependent on pigment concentration. Furthermore, the degradation of R-PE was maximum in CE-Gb without preservatives, and the addition of ascorbic acid (AA) reduced the color loss of the pigment during storage. G. birdiae proved to be a potential source of R-PE, which can be used as a dye in the food industry.
r -藻红蛋白(R-PE)是一种存在于藻类中的红色色素，在生物技术工业中具有潜在的应用前景。本文研究了江蓠(Gracilaria birdiae, CE-Gb)中r -藻红蛋白的理化性质及抗氧化活性。并对该色素在不同添加剂下的光谱稳定性进行了评价。结果表明，抗氧化活性与色素浓度有关。在不添加防腐剂的CE-Gb中，R-PE的降解率最高，抗坏血酸(AA)的添加降低了色素在储存过程中的颜色损失。鸟类被证明是R-PE的潜在来源，可以用作食品工业的染料。

ABSTRACT A modified method to extract chitosan from crustacean shell waste is presented. Separate steps for deproteinization, decolorization, and deacetylation were replaced with single-step steeping in an alkali solution for 24 h. This method resulted in 33.26%, 11.39%, and 10.15% of chitosan yield, respectively from whiteleg shrimp, blueswimming crab and giant freshwater prawns whilepreserving physicochemical properties, which was evident by FTIR, XRD, SEM, EDS, ash, viscosity, colour, and antioxidant values. A comparison with the conventional heating method shows 8.10% chemical and 13% energy savings and comparative simplicity of the modified method showing potential to be executed at the industrial level.

ABSTRACT The aim of the study is to incorporate seaweed powder (Caulerpa racemosa) at different percentages in pasta. The increasing level of seaweed in pasta increases the nutritional composition compared to control pasta. In seaweed incorporated pasta, FTIR analysis confirms the enrichment of seaweed polyphenols due to the presence of functional group in the wavenumber 3761.81 cm−1 and the microstructure studies exhibited a better protein starch network. Phenolic content and DPPH radical scavenging activity are also found to be enhanced. Sensorily, the 5% seaweed powder incorporated pasta was well accepted, with high amino acid and fatty acid contents, and high antioxidant properties.

ABSTRACT The effectiveness of B. ciliata in sous-vide processed tilapia fillets during storage under refrigerated conditions (2°C) for a study period of seven weeks was studied. Significant changes between treatment and control were seen from the 21st day (p < .05), with the treated sample being of superior quality. The final PV, TBARS, and SPC on the 49th day of storage was 8.22 ± 0.18 mEq O2/kg, 0.87 mg MDA/kg, and 4.72 ± 0.22 log cfu/g, respectively, for control. Samples sous-vide treated with herb maintained higher values for the sensory attributes and instrumental hardness throughout the storage period.

ABSTRACT Histamine-producing bacteria (HPB) were isolated from Longtail and Eastern Little tuna harvested from Indonesian waters and processed as salted-boiled fish (SBF). Mesophilic and psychrophilic bacteria were isolated on Niven’s agar, screened for histidine decarboxylase activity and the presence of the hdc gene, and then histamine production was quantified. Six genera of HPB were identified: Enterobacter, Erwinia, Hafnia, Klebsiella, Serratia and Shigella. At stationary growth phase , mesophilic isolates produced approximately 400 times more histamine than psychrotrophic isolates. The proportion of hdc-positive isolates increased with SBF processing steps, indicating the importance of food safety measuresto minimize HPB growth and histamine production.

ABSTRACT In this study, seasonal changes in the muscle tissue, total lipid, and fatty acid composition of phospholipid (PL), triacylglycerol (TAG), and phospholipid classes of female Capoeta umbla were investigated. Fatty acid compositions of TAG and PL classes were found to be different in C. umbla muscle. Percentages of myristic acid, 16:1n-7, 18:1n-9, monounsaturated fatty acid (ΣMUFA), linoleic acid (18:2n-6), and linolenic acid (18:3n-3) were found to be higher in TAG than the values determined in PL classes. In PL classes, 16:0, 18:0, arachidonic acid (20:4n-6, AA), EPA (20:5n-3), DHA (22:6n-3), and polyunsaturated fatty acid (ΣPUFA) were higher than TAG fraction.

ABSTRACT In this study, the yield of gelatin extraction from fish waste was optimized using response surface method. The highest yield was obtained with 0.8% citric acid concentration at 72.95°C for 58 minutes. Then, fish gelatin was modified using ultraviolet radiation to overcome fish gelatin defects including unsuitable rheological properties and low thermo-stability. UV irradiation can create crosslinks via alkyl or phenyl groups of the proteins. The modified sample also showed the highest melting point due to the creation of cross-links and improved emulsification and foaming properties of fish gelatin through structural modification and increased surface hydrophobicity of gelatin.

ABSTRACT This study showed that the dark muscle of yellowtail stored in pure O2 had almost unchanged redness, pH, and MetMb formation during 72-hour storage, while the N2 and air groups had significantly lower redness and pH, and significantly higher MetMb formation indices. Lactic acid content showed a significant negative correlation with pH. Pearson correlation analysis demonstrated that the lower redness was correlated with the lower pH and higher MetMb formation index. Thus, pure O2 could inhibit the MetMb accumulation and decrease pH, thereby suppressing discoloration and making the dark muscle more likely to gain bright red color.
