The study was conducted in aims to investigate the effects of frozen storage and cooking conditionson proximate compositions and formaldehyde content (FA) in some selected fish from three different sourcesin Bangladesh. Proximate composition in fresh and final frozen samples was determined by standard AOACmethod and FA content in fresh, frozen stored, and cooked samples was determined by spectrophotometricmethod. Among the studied fishes, marine fish contained higher protein (except Rita), lipid, and ash followedby estuarine and culture fish samples. Protein, moisture and ash content decreased and lipid content increasedsignificantly (p<0.05) during frozen storage for all samples and sources. The FA was lower in cultured fishsamples compared to that of the river and marine fish samples, both at fresh and end of frozen storage. Atfresh condition, FA content in all samples ranged from 0.41 to 0.71µg/g, 0.51 to 0.89µg/g, and 0.73 to1.69µg/g which increased to 0.95 to 2.11µg/g, 1.74 to 1.95µg/g, and 3.22 to 5.20µg/g at end of the storageperiod, respectively (p<0.05). Further, FA content significantly decreased after cooking in all the fishsamples (p<0.05). However, irrespective of fish species and sources, the FA content was higher than WHOrecommended value (0.2 µg/g). The study findings revealed that longer frozen storage of fish could be apublic health concern to the consumers.

Currently, monitoring of persistent organic pollutant (POP) content in various biological and environmental matrixes in the Arctic is an urgent task. The present study focused on the determination of POPs such as: PCB#28, PCB#52, PCB#101, PCB#105, PCB#118, PCB#123, PCB#153, PCB#128, p,p’-DDE, o,p’-DDE, p,p’-DDD, o,p’-DDD, hexachlorobenzene (HCB), cis-nonachlor, trans-nonachlor, cis-chlordane, trans-chlordane, mirex, 1,2,3,5-tetrachlorobenzene and 1,2,4,5-tetrachlorobenzene in fish consumed by the indigenous people of the Nenets Autonomous Okrug (NAO) of the Russian Arctic. Fish samples were analyzed by gas chromatography triple quadrupole mass spectrometry (GC-MS/MS) using the multiple reaction monitoring (MRM) technique. The obtained results show that the major POPs in fish were dichlorodiphenyltrichloroethane (DDT) breakdown products and polychlorinated biphenyls (PCB) congeners. The ∑PCB8 in pink salmon, Arctic char, navaga, humpback whitefish and northern pike were 1.54, 1.58, 1.24, 0.72 and 0.32 ng/g (ww), respectively. The main PCB congeners maximum average medium concentrations were 0.68 ng/g (ww) and 0.51 ng/g (ww) of PCB#153 in navaga and PCB#128 in pink salmon, respectively. The main DDT breakdown product was p,p’-DDE. In Arctic char, pink salmon, navaga, humpback whitefish and northern pike, the concentration of p,p’-DDE was 0.58, 1.61, 0.49, 0.63 and 0.08 ng/g (ww), respectively. A moderate positive relationship between ∑PCB8 and lipid content and a high positive relationship between ∑DDT and lipid content were observed. In fish samples with fat content <0.5% (northern pike, humpback whitefish), the amount of analyzed POPs was 2 or more times lower than that in fish species with fat content >1% (pink salmon, Arctic char). Despite the large number of fish in the diet of indigenous peoples from NAO, no significant risks were identified. Most legacy POP and organochlorine pesticides (OCPs) tend to decrease, which can be explained by past national and regional bans and restriction on their use and emission.

The production and determination of the nutritional properties of cookies produced by partial substitution of margarine with avocado pear pulp was studied. Well cleaned avocado pear was blended into paste and used to substitute margarine in the prepared cookies. The ratio of avocado pear pulp substituted was 20%, 30%, 40% and 50%. The substituted products and the control (100% margarine) were subjected to physicochemical and sensory evaluation. The results of the proximate analysis showed that the protein content ranged from 6.93% -7.83% with sample A having the highest protein content and fat content. Moisture content and ash content of samples were seen to be higher in sample E (50:50 ratio). Sample A had the least value of moisture, ash and crude fibre with moisture content of 11.13%, ash content of 1.40% and crude fibre value of 0.29%, while sample E  recorded the least value of crude fat  (16.00%). The carbohydrate content was recorded to be higher in sample C. The physical properties showed that cookies made with higher avocado pear pulp had less thickness compared to the control cookies. The sensory evaluation results showed that sample A had the highest values of 8.05%, 7.85% and 7.95% for appearance, taste and aroma respectively while sample E (50:50 ratio) had the least values in crunchiness, taste and aroma. The overall acceptability of the results showed that sample A recorded the highest value but not significantly different (p<0.05) from sample B (80:20 margarine avocado). The research concluded that the partial substitution of avocado improved the nutritional value of the cookies by lowering the saturated fat content.

Fat content is one of the most important parameters of beef grading. In this study, a hyperspectral imaging (HSI) system, combined with multivariate data analysis, was adopted for the classification of beef grades. Three types of beef samples, namely Akaushi (AK), USDA prime, and USDA choice, were used for HSI image acquisition in the spectral range of 400–1000 nm. Spectral information was extracted from the image by applying the partial least squares discriminant analysis (PLS-DA) for the three classifications. A total of eight different types of data pre-processing procedures were tested during PLS-DA to evaluate their individual performance, with the accepted pre-processing method selected based on the highest accuracy. Chemical and binary images were generated to visualize the fat mapping of the samples. Quantitative analysis of the samples was performed for the reference measurement of the dry matter and fat content. The highest overall accuracy, 86.5%, was found using the Savitzky–Golay second derivatives pre-processing method for PLS-DA analysis. The optimal wavelength values were found from the beta coefficient curve. The chemical and binary images showed significant differences in fat mapping among the three groups of samples, with AK having the greatest intramuscular fat content and USDA choice having the least. Similar results were observed during the proximate analysis. The findings of this study demonstrate that the HSI technique is a potential tool for the fast and non-destructive determination of beef grades based on fat mapping.
