Protein, lipid, ash and moisture content in the body muscles of two commonly available puffer fish species in Bangladesh (Leiodon cutcutia and Dichtomyctere fluviatilis) have been analysed from January 2018 to June, 2018. The puffer fish species were collected from different habitats i.e., Leiodon cutcutia from freshwater and Dichtomyctere fluviatilis from estuarine water. The percentage of the proximate composition varied in different months in both the species. In Leiodon cutcutia, moisture content fluctuated from 79.32% to 87.61% with an average of 83.75%; protein content from 6.35% to 13.31% with an average of 9.49%; lipid content from 1.57% to 2.32% with an average of 1.92% and ash content from 2.30% to 3.27% with an average of 2.84%. In Dichotomyctere fluviatilis, moisture content fluctuated from 73.77% to 84.18% with an average of 77.49%; protein content from 10.03% to 19.77% with an average of 16.80%; lipid content from 0.92% to 1.71% with an average of 1.32% and ash content from 2.77% to 3.34% with an average of 3.05%. The comparative evaluation of the nutritional value of the studied fish species revealed that the puffer fish from estuarine environment might contain higher amount of nutrients. Thus, proper utilization of this species towards sustainable management, nutritional composition and biosecurity issues will lead to achieve sustainable blue economy. Jahangirnagar University J.

The present study was carried out to determine the proximate composition of green tiger prawn and to select the suitable solvent system for carotenoid extraction. Samples (P. semisulcatus) were purchased from the landsites and transported to the laboratory in an ice box. The whole shrimp were peeled manually, and the residues, consisting head, tail and shells are separated. The moisture content, total lipid, protein, and ash content were quantified using standard methods. Weight of extracted crude of shrimp shells and retention factor (Rf) for the shrimp shell powder were determined using different pure and mixed organic solvents. Moisture content of the fresh shrimp shells was found to be 76.40 ± 0.92 %. In the present study, quantification showed that the shrimp shells are significantly rich in ash content (25.52 ± 0.06 % in dry weight). Significantly (p < 0.05) the highest crude yield of 10.24 ± 0.02 % was obtained from shrimp shells, when the dried shrimp shells powder was dissolved with the mixture of acetone and ethanol (1:1) than the other solvents. The lowest crude yield (2.32 ± 0.01 %) was extracted with ether. The highest Rf was obtained when the shrimp shell crude was dissolved with the mixture of acetone and ethanol (1:1). It can be recommended from our findings that the dried shrimp shells of Peneaus semisulcatus would be directly utilized for formulations of poultry animal feeds and sea cucumber juvenile feeds due to its high ash content. The mixture of the acetone and ethanol (1:1) would be the better choice for obtaining the highest crude yield from the shrimp shells.

Calliblepharis jubata is an edible red seaweed and a carrageenan primary producer, considered native in Figueira da Foz (Portugal). C. jubata has the particularity of producing only one kind of carrageenan, the iota fraction. However, this seaweed is not yet valuable for the food industry or even for human consumption. In this work, we characterize important biochemical compounds of C. jubata growing up within different cultivation techniques and wild specimens. The aim of this work is to know if there are differences between the biological compounds of interest and identify the advantages for human consumption and the food industry. The results supported the nutritional value of the seaweed, where the ones from inshore cultivation (T) were more identical to the wild specimens (F), than the indoor C. jubata (A, B, C). The parameters analyzed were fatty acids, carbohydrates and carrageenan content.

Se estudiaron la variación estacional de la composición química proximal y el contenido energético de la carne de las pianguas Anadara tuberculosa y A. similis. Mensualmente, entre marzo de 2010 y febrero de 2011, se recolectaron de 15 a 20 ejemplares de cada especie. La composición proximal se determinó siguiendo la metodología recomendada por la Asociación Oficial de Químicos Analíticos (AOAC). El valor promedio de las proteínas de la carne de A. similis fue de 57.9 ± 7.2%, carbohidratos 25.6 ± 4.4%, cenizas 6.87 ± 0.23% y lípidos 9.2 ± 0.2%. El contenido calórico promedio fue de 5.3 ± 0.2 kcal/g. Para A. tuberculosa se calculó 61.6% de proteínas, 21.6% de carbohidratos, 8.8% de cenizas, 7.9% de lípidos; el valor calórico fue de 5.2 kcal/g. Se puede concluir que tanto A. tuberculosa como A. similis presentan valores nutricionales óptimos para el consumo humano, por su bajo contenido de grasa y su aceptable contenido proteico. Abstract The seasonal variation in proximate biochemical composition and energy content of Anadara tuberculosa and A. similis were studied between March 2010 and February 2011 on a monthly basis. Fifteen to twenty individuals of each species were collected monthly. The proximate composition was determined following the methodology recommended by the Association of Official Analytical Chemists (AOAC). The average value of meat protein in A. similis was 57.9 ± 7.2%, carbohydrate 25.6 ± 4.4%, ash 6.87 ± 0.23%, and lipids 9.2 ± 0.2%. The average caloric content was 5.3 ± 0.2 kcal/g. For A. tuberculosa the values were protein 61.6%, carbohydrate 21.6%, ash 8.8%, and lipids 7.9%. The caloric value was 5.2 kcal/g. It can be concluded that both A. tuberculosa and A. similis have optimal nutritional value for human consumption, due to their low lipid and high protein contents.

Introduction: Honey is widely known as a natural product which is collected from various plants by bees. The aim of this study was conducted to determine the proximate composition (moisture, ash, crude protein, total fat, dietary fiber and total carbohydrate) of four Malaysian honey samples. Methods: TB1 (Trigona bee honey from Kedah), TB2 (Trigona bee honey from Kelantan), TU1 (Wild Tualang bee honey from Pahang) and TU2 (Tualang bee honey was collected from a farm from Pahang) were examined for their proximate compositions. Proximate composition was determined using the methods of AOAC (1990; 1995; 2003). Results: Moisture content was significantly the highest (p<0.05) in TB2 with a value of 30.586± 0.109 g/100g and the lowest in TU2 with a value of 18.914± 0.264 g/100g. TB2 had significantly (p < 0,05) higher ash content than other examined samples with a value of 0.766±0.010 g/100g. Protein content of TU1was significantly higher than the other analyzed honey samples with a value of 1.776±0.04 g/100g. The total fat content of TB2 was significantly lower than the other honey samples. Dietary fiber of TB1 was found to be significantly higher compared to the others with a value of 0.612±0.027. Total carbohydrate content was significantly (p<0,05) the highest in TU2 compared to other samples  with a value of 79.980±0.280 g/100g. Conclusions: All honey samples are good sources of nutrients for human consumption. Moreover, the differences in the components of the different honey samples were probably connected with the variances in the floral sources

Biofortified yellow-fleshed cassava is important in countries with high cassava consumption, to improve the vitamin A status of their populations. Yellow- and white-fleshed cassava were evaluated over three locations for proximate composition and cyanide content as well as retention of carotenoids after boiling. There was significant variation in the crude fiber, fat, protein and ash content of the genotypes. All but one of the yellow-fleshed cassava genotypes recorded higher protein values than the white-fleshed local genotypes across locations. The cyanide content of the genotypes varied between locations but was within the range of sweet cassava genotypes, but above the maximum acceptable recommended limit. Micronutrient retention is important in biofortified crops because a loss of micronutrients during processing and cooking reduces the nutritional value of biofortified foods. Total carotenoid content (TCC) ranged from 1.18–18.81 μg.g−1 and 1.01–13.36 μg.g−1 (fresh weight basis) for fresh and boiled cassava, respectively. All the yellow-fleshed cassava genotypes recorded higher TCC values in both the fresh and boiled state than the white-fleshed genotypes used as checks.

A novel method was developed for the determination of linting propensity of paper based on printing with an IGT printability tester and image analysis of the printed strips. On average, the total fraction of the surface removed as lint during printing is 0.01%-0.1%. This value is lower than those reported in most laboratory printing tests, and more representative of commercial offset printing applications. Newsprint paper produced on a roll/blade former machine was evaluated for linting propensity using the novel method and also printed on a commercial coldset offset press. Laboratory and commercial printing results matched well, showing that linting was higher for the bottom side of paper than for the top side, and that linting could be reduced on both sides by application of a dry-strength additive. In a second case study, varying wet-end conditions were used on a hybrid former machine to produce four paper reels, with the goal of matching the low linting propensity of the paper produced on a machine with gap former configuration. We found that the retention program, by improving fiber fines retention, substantially reduced the linting propensity of the paper produced on the hybrid former machine. The papers were also printed on a commercial coldset offset press. An excellent correlation was found between the total lint area removed from the bottom side of the paper samples during laboratory printing and lint collected on halftone areas of the first upper printing unit after 45000 copies. Finally, the method was applied to determine the linting propensity of highly filled supercalendered paper produced on a hybrid former machine. In this case, the linting propensity of the bottom side of paper correlated with its ash content.

This paper presents a method of sorption using peat for elimination of emergency spills of crude oil and petroleum products and the possibility of energy use of oil-saturated peat. The results of assessment of the sorbent capacity of peat are presented, with waste motor oil and diesel fuel chosen as petroleum products. Natural peat has been found to possess sorption properties in relation to petroleum products. The sorbent capacity of peat can be observed from the first minutes of contact with motor oil and diesel fuel, and significantly depends on their viscosity. For the evaluation of thermal properties of peat saturated with petroleum products, experimental studies have been conducted on determination of moisture and ash content of as-fired fuel. It is shown that adsorbed oil increases the moisture and ash content of peat in comparison with the initial sample. Therefore, when intended for energy use, peat saturated with petroleum products is to be subjected to additional drying. Simulation of net calorific value has been performed based on the calorific values of peat and petroleum products with different ratios of petroleum product content in peat and for a saturated peat sample. The obtained results are compared with those of experiments conducted in a calorimetric bomb and recalculated for net calorific value. A satisfactory discrepancy is obtained, which amounts to about 12%. Options have been considered providing for combustion of saturated peat as fuel (burnt per se and combined with a solid fuel) and processing it to produce liquid, gaseous and solid fuels. Peat can be used to solve environmental problems of elimination of emergency spills of crude oil and petroleum products and as an additional resource in solving the problem of finding affordable energy.

<em>Sweet potato is an important staple food crop especially for the local people of Central Highlands Jayawijaya. There are many accessions that have always been maintained its existence to enrich their various uses. Traditionally, sweet potato accessions were grouped based on the utilization, such as for animal feed, cultural ceremonies, consumption for adults, as well as for infants and children. This study was aimed to analyze the nutritional value of sweet potatoes consumed by infants and children of the Dani tribe. Chemical analyses were conducted at the Laboratory of Post-Harvest Research and Development Center, Cimanggu, Bogor. The results showed that each of 4 (four) sweet potato accessions which were consumed by infants and children had good nutrient levels. Accession Sabe showed the highest water content (72.56%), vitamin C (72.71 mg/100 g), Fe (11.85 mg/100 g), and K levels (130.41 mg / 100 grams). The highest levels of protein (1.44%), fat (1.00%), energy (154.43 kkal/100 gram), carbohydrate (35.47%), starch (30.26%), reducing sugar (3.44%), riboflavin (0.18 mg/100 g), and vitamin A (574.40 grams IU/100 were produced by accession Manis. On the other hand, accession Saborok produced the highest value for ash content (1.32%), vitamin E (28.30 mg/100 g), and ?-carotene (64.69 ppm). The highest level of crude fiber (1.81 %) and thiamin (0.36 mg/100 g) was produced by accession Yuaiken.</em>
