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.

Teff and amaranth are gluten-free cereals with significant nutritional and health benefits. However, they are underutilized and known in limited areas of the world. The present study evaluated the fatty acid profile, crude fat, squalene content and lipid quality of seven teff (Eragrostis teff (Zucc.) Trotter) and three amaranth (Amaranthus caudatus L.) varieties from Ethiopia. The fat content ranged from 2.92 to 3.34% (averaging 3.06%) and from 8.28 to 9.21% (averaging 8.6%) for teff and amaranth, respectively. Linoleic, oleic and palmitic acid were predominant in both teff and amaranth, accounting for approximately 89 and 85% of total fatty acid content, respectively. The saturated to unsaturated fatty acids ratio ranged from 0.30 to 0.32 in teff and from 0.38 to 0.40 in amaranth. The parameters used to describe lipid quality, i.e., thrombogenicity and atherogenicity indices, show that teff was superior over amaranth, suggesting a preference for the former for healthy food formulation. The squalene content of white amaranth (486.54 mg/100 g DM) was significantly higher than that of the other two varieties (327.54 and 340.81 mg/100 g DM for red and brown amaranth, respectively). In general, both gluten-free crops should be exploited for their potential as ingredients for the development of novel functional foods.

<p>Three wild populations of crucifix crab<em> Charybdis feriatus</em> 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<em> C. feriatus</em> from Zhoushan (ZS) and Xiapu (XP) (84.84%-88.35%) were significantly higher than that of crucifix crab<em> C. feriatus</em> 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<em> C. feriatus</em> from QH (5.36%). The muscle of crucifix crab<em> C. feriatus</em> 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 (<em>P </em>&lt; 0.05). The total saturated and unsaturated fatty acid content in the muscle of crucifix crab<em> C. feriatus </em>from three wild populations showed significant difference (<em>P </em>&lt; 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 (<em>P </em>&lt; 0.05). Overall, the differences in chemical composition in muscle of <em>C. feriatus </em>from different locations<em> </em>could be attributed to environmental variables and maturation stage.</p>

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.

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

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.

Meat from rabbits offers high nutritive properties as it has high levels of essential amino acids, minerals and vitamins. Rabbit meat is also regarded lean, since it contains less fat than many other meat types. The composition of rabbit meat lipids is also favourable due to higher contents of unsaturated fatty acids compared to other types of meat. The aim of the present study was to examine and compare meat quality from male and female rabbits. A total of 24 rabbits (12 males and 12 females) were used. The rabbits were slaughtered at an age of 17–18 weeks. The following parameters were studied: slaughter traits, colour, pH, cooking loss, tenderness, total fat content and water holding capacity (WHC). Interestingly, the ultimate pH was significantly lower in male compared to female rabbits (p = 0.008). Moreover, cooking losses were higher in the meat from male rabbits (p = 0.001). No other relevant differences were found between meat from male and female rabbits suggesting that sex might be regarded as a minor factor in the production of rabbit meat at the chosen slaughter age.

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.

Perkembangan dunia perbankan syariah tidak lepas dari peran para nasabah yang memberikan kepercayaan terhadap pihak perbankan untuk penyimpanan asset keuangannya. Faktanya banyak kelompok nasabah yang memutuskan untuk menjadi nasabah di perbankan syariah karena faktor religiusitasnya. Faktor lain yang dapat ikut mempengaruhi keputusan nasabah adalah kualitas produk. Di mana kualitas produk merupakan karakteristik yang melekat dari suatu produk. Kemungkinan yang terjadi bahwa kebanyakan nasabah pada perbankan syariah juga masih merupakan nasabah perbankan konvensional.Tujuan yang ingin dicapai dalam penelitian ini adalah untuk mengetahui pengaruh kualitas produk dan tingkat religiusitas nasabah terhadap keputusan nasabah untuk menyimpan dananya atau tidak di BSM Cabang Purwokerto. Alat analisis yang digunakan adalah analisis regresi linier berganda, dengan jumlah sampel 100 nasabah. Diperoleh hasil Y = 5,046 + 0,101X1 + 0,218X2. Berdasarkan uji F yang sudah dilakukan maka dapat diketahui bahwa variabel kualitas produk dan religiusitas secara bersama – sama berpengaruh terhadap keputusan nasabah untuk menyimpan dananya di BSM Cabang Purwokerto. Berdasarkan uji t yang sudah dilakukan dapat diketahui bahwa secara partial baik variabel kualitas produk maupun variabel religiusitas berpengaruh terhadap keputusan nasabah untuk menyimpan dananya di BSM Cabang Purwokerto. The progress of the Islamic bank cannot be separated from the role of its customers who give trust to the bank to deposit their financial assets. It is a fact many groups of customers decide to be the customers of the Islamic bank because of their religiosity. The other influences factor of a customer’s decision is the quality of the product. The aim of this research was to determine the effect of product quality and level of customers’ religiosity towards customers’ decision whether to keep their funds in Syariah Mandiri Bank, Branch of Purwokerto, or not. The analytical tool used was multiple linear regression analysis, with a sample of 100 customers. The results indicate Y = 5,046 + 0,101X1 + 0,218X2. Based on F, it can be seen that both variables of product quality and religiosity simultanously affect the customers’ decision to keep theirfunds in BSM Branch of Purwokerto. Based on t test, it can be seen that independently, either variable of product quality or variables of religiosityinfluences the customers’ decision to keep their funds in BSM Branch of Purwokerto.
