A comparative evaluation of the nutritional quality of three wild populations of female mitten crabs (Eriocheir sensu stricto) in northern China

Abstract There are three major wild populations of mitten crab (Eriocheir sensu stricto), Suifenhe River (SF), Tumenjiang River (TM) and Liaohe River (LH) in northern China. However, the information on the nutritional quality of these three populations of crabs is still scarce. Thus, we investigated and compared the tissue indices, total edible yield, proximate composition, fatty acid compositions and amino acid contents of these wild crab populations. We showed that: (1) TM population had the highest meat yield among the three populations; (2) TM recorded the highest moisture and the lowest total lipid content in ovary and muscle; (3) a higher level of total n-3 poly-unsaturated fatty acids was found in TM, except for the ovary in SF; (4) the three populations had similar essential amino acids scores. In conclusion, Eriocheir s.s. from these three populations all showed a high nutritional quality suitable for humans, especially the TM, which contains more eicosapentaenoic acid and docosahexaenoic acid.

Abstract The Japanese mitten crab Eriocheir japonica is an economically important species widely distributed throughout the East Asia region, but information on the compositional characteristics and nutritional quality of E. japonica is still scarce. Thus, this study was conducted to compare the edible tissue indices, proximate composition, fatty acid profiles and amino acid contents between wild E. sinensis and E. japonica. It showed that: (1) both E. sinensis and E. japonica have a high total edible yield (approximately 40%); (2) E. sinensis and E. japonica have a similar proximate composition, except for total lipids; (3) female E. japonica have higher percentages of C18:3n3, C20:5n3 and C22:6n3; (4) E. sinensis have higher levels of essential amino acids than E. japonica in muscle. In conclusion, these results demonstrated that wild E. japonica is rich in omega-3 fatty acids, and both E. sinensis and E. japonica are aquatic food of high nutritional value, with a high edible yield.

Significant Difference

Three wild populations of crucifix crab Charybdis feriatus were sampled and muscle was analyzed for proximate composition, amino acid and fatty acid composition, aimed to quantify and compare the nutritional quality from three different locations in China. Results showed that crude protein content in muscle of female crucifix crab C. feriatus from Zhoushan (ZS) and Xiapu (XP) (84.84%-88.35%) were significantly higher than that of crucifix crab C. feriatus from Qionghai (QH) (74.33%), while there was no significant difference in terms of crude fat content (3.82%-4.07%). The highest content of ash was found in muscle of crucifix crab C. feriatus from QH (5.36%). The muscle of crucifix crab C. feriatus from ZS and XP had significantly higher contents of total amino acids, essential amino acids, non-essential amino acids and delicious amino acids than those of QH group (P < 0.05). The total saturated and unsaturated fatty acid content in the muscle of crucifix crab C. feriatus from three wild populations showed significant difference (P < 0.05). The ZS group had highest content of poly-unsaturated fatty acids (33.64%) and total content of EPA and DHA (22.85%) as well, followed by XP and QH group (P < 0.05). Overall, the differences in chemical composition in muscle of C. feriatus from different locations could be attributed to environmental variables and maturation stage.

n the current paper, we aimed to analyze the way in which packing (different polyethylene types) influence the quality of pasteurized melange during storage, packing being realized in units of 1 kg (Tetra Pak) (batch Lexp-1) and units of 5 kg (Bag in box) (batch Lexp-2). Products were stored during a period of 28 days at a temperature of +4�C, qualitative determinations being realized in first day (day 0), at 7 days, at 14 days, 21 days and in day 28 of storage. Were effectuated a sensorial examination and chemical analysis were was established the content in dry matter (%), water (%), proteins (%), content in essential amino acids (isoleucine, methionine, tryptophan, phenylalanine) and non-essential amino acids (alanine, histidine, glycine, serine) (mg/100g) as well as the content in lipids (%) establishing their profile by identification of some saturated fatty acids (16:0 mg/100g and 18:0 mg/100g) and unsaturated fatty acids (16:1 mg/100g and 18:1 mg/100g). After sensorial examinations, the first modifications were observed at the checking effectuated in day 21 for batch Lexp-2, the obtained score being of 18 points, and at checking effectuated in day 28 was given a score of 18 points for melange belonging to batch Lexp-1 and only 14 points for melange from batch Lexp-2. Differences were recorded also in case of chemical composition of products, so for protein content at batch Lexp-1 in first checking day was obtained a mean of 12.730�0.24% and at batch Lexp-2 12.614�0.22%. Differences between those two batches were insignificant (p[0.05). In case of fat content, at the end of storage period was obtained a mean of 11.256�0.06% for batch Lexp-1 and 11.244�0.11% for batch Lexp-2, differences being insignificant (p [ 0.05). Regarding the profile of amino acids and fatty acids, the mean values obtained during whole storage period oscillated from one stage to another, but the differences between those two batches were insignificant (p [ 0.05). Pasteurized egg melange suffers certain sensorial modifications during storage, especially on consistency and colouring, modifications which are accentuated mainly by storage conditions. Type of polyethylene utilized for this product hadn�t influenced the nutritive qualities of product.

Formation Phase

The paper presents the results of long-term research on the infl uence of pinching of Northern ecotype soybeans (Okskaya variety) on yield, protein, and oil productivity in high latitudes (57°), a long day, a limited amount of active temperatures (1700…2000 °C) on sod – podzolic soils of the Non-Chernozem zone of the Russian Federation. The authors determine the prospects of using the method for varieties of an indeterminate type of growth. The pinching of crops was carried out three times: at the beginning of the fl owering phase, in the middle of the fl owering phase, and at the beginning of the bean formation phase. It was found that the pinching of crops carried out at the beginning of the bean formation phase, reduces the duration of the growing season by an average of 15 days. The technique ensures a more than double increase in the number of side shoots. The share of the coarse fraction of seeds was about 89%, the yield of seeds reached up to 2.00 t/ha, the protein content in seeds – up to 42.2%, fat – up to 19.1%, protein collection from the seed yield – up to 0.834 t/ha, essential amino acids in protein – up to 0.459 t/ha, fat – up to 0.380 t/ha, collection of unsaturated fatty acids – up to 0.228 t/ha. It is shown that the technique allows optimizing the ripening processes without reducing the productivity and quality of the crop, while the costs of pinching are paid off by reducing the costs of harvesting. The obtained data can be used to optimize soybean growing technologies at the northern border of the soy cultivation

Nutritional Benefits

This short review compiles the data concerning the quality of flesh, processed roe and smoked fillets of grey mullets (Mugilidae), including when available the data concerning the fish from freshwater and in particular those from Tunisian reservoirs. The biochemical and mineral composition of the fish, the nutritional benefits and the potential health risks related to the consumption of fish products are discussed with regard to human health, taking into consideration the nutritional recommendations and normative toxicological limits defined by leading health authorities. Flesh proximal compositions of fish from freshwater are relatively scarce, but the few available lipid data are within the very large proximal range (from less than 1% to more than 11%) reported for grey mullets in general. Most of the studies reveal the predominance of unsaturated fatty acids with a substantial proportion ω3 type not only for fish from marine environment but also for those from freshwater. Flesh constitutes a source of essential amino acids and mineral nutrients too. The mullets are generally reported to be safe for human consumption except the fish from heavily contaminated zones. Globally, it should be regarded as an interesting contribution to a healthy diet. The mullets are also greatly appreciated for the production of salted and dried roe as well as smoked fillets, which allow increasing their economic value while preserving products health beneficial attributes. Data concerning processing mullet's roe from freshwater are missing, but it may be supposed that these roes have acceptable texture, taste and flavour as they are highly sought by connoisseurs. It is recommended to perform studies on the qualities of freshwater mullet's roe and to look for labelling the origin for both the roes and the smoked fillets of mullet from Tunisian reservoirs dedicated to the production of drinking water as it would guarantee that the fish come from unpolluted environments.

Phloem Feeder

Abstract D. noxia has a great economic impact on cereal crops (Brooks et al., 1994). It is a phloem feeder like other aphids and the symptoms evident on plants are a result of this feeding mechanism. By feeding on the phloem, the aphid damages the plants through nutrient drainage (Dixon, 1985) which results in chlorosis, necrosis, wilting, stunting, and curling of the leaves, misshapen or nonappearance of new growth, and localised cell death at the site of aphid feeding. D. noxia further elicits an increase in essential amino acids in the phloem sap by triggering the breakdown of proteins in infested wheat leaves (Burd and Burton, 1992; du Toit, 1986; Ma et al., 1998; Miller et al., 2001). The damage to the foliar tissue is thought to play a role in the pest's ability to increase nutritional quality of the host plant (Botha et al., 2006).

Fat Supplements

The nutritional characteristics of rumen-protected protein and fat supplements produced by formaldehyde treatment of oilseeds and meals are reviewed. The proportion of rumen undegraded protein (RUP) in different protein sources can be controlled by this process, bio-available lysine is 82–84% and the proportions of acid detergent and neutral detergent insoluble nitrogen are unchanged by formaldehyde treatment; this is in contrast to heat treatment of proteins where significant increases in these nitrogen components can occur if the RUP content exceeds 60% of the crude protein (CP). A RUP content of 75–80% of CP is optimal when using protein supplements for milk production, and for body growth in steers a lower RUP content is desirable (i.e. 50–55% of CP). Both the fat and protein constituents in rumen-protected fat supplements derived from the emulsification and formaldehyde treatment of oilseeds are highly protected from ruminal metabolism (75–90%) and are readily digested in the small intestine (90% for C18 unsaturated fatty acids, 82% for the essential amino acids). Protected fat/protein supplements are designed and fed to lactating and non-lactating ruminants to increase efficiency of production, enhance product quality, augment n-3, n-6 and n-9 fatty acid content of meat and milk, and to improve reproductive performance. The challenges and potential role for these protected fat/protein supplements in improving productivity and quality of ruminant derived foods are discussed.
