Cirrhinus Molitorella

Proximate body composition and amino acid profile of flesh of wild Cirrhinus molitorella (Valenciennes, 1844) from a reservoir and a river was compared with that of C. molitorella cultured in an aquaculture pond. The results showed the fat content to be highest in C. molitorella caught from reservoir followed by samples from river and lowest in pond cultured fishes. Protein content exhibited the opposite trend. Flesh of C. molitorella from river had optimum protein quality while flesh of fishes from reservoir had the best taste. Flesh of C. molitorella was found to be nutritionally rich and well balanced and its high glutamic acid as well as lysine content made it a superior forage fish for Siniperca chuatsi. Overall, C. molitorella flesh had a more balanced nutritional composition, but lower nutritional value than that of seven other reference fish species.

Quinoa (Cheopodium quinoa), kañiwa (Cheopodium pallidicaule), kiwicha (Amaranthus caudatus) and tarwi (Lupinus mutabilis) are ancient crops from the Andean region of South America. Recently, interest in these crops has grown, and worldwide demand for them has increased considerably. The aim of this study was to study the bioactive compounds and nutritional compositions of different varieties/ecotypes of quinoa, kañiwa, kiwicha and tarwi. Proximate, mineral, dietary fibre, fatty acid and amino acid compositions were evaluated. The content of phenolic compounds, tocopherols and phytosterols, and the folic acid and antioxidant capacity, were determined as well. The protein content of the grains was between 13.00% and 20.00%. More important than protein quantity is protein quality, which is demonstrated by the composition of the amino acids. All analysed grains, and especially the kañiwa, had very high lysine content. This amino acid is especially important in vegetarian diets because it is the limiting amino acid in cereal protein. The content of the total phenolic compounds in the studied grains was 27–58 mg gallic acid/100 g of sample. In quinoa, the principal flavonoids found were quercetin and kaempferol, in kañiwa quercetin and isorhamnetin. In kiwicha, no detectable amounts of flavonoids were found. Plant sterols (phytosterols) were another group of biologically active compounds detected. Andean lupin, tarwi, is very rich in oil, which has a beneficial nutritional composition. In conclusion, all studied grains have a very high nutritional value, are interesting sources of bioactive compounds and could be used as ingredients in health-promoting functional foods.

The Impact

Quinoa cultivation has been expanded around the world in the last decade and is considered an exceptional crop with the potential of contributing to food security worldwide. The exceptional nutritional value of quinoa seeds relies on their high protein content, their amino acid profile that includes a good balance of essential amino acids, the mineral composition and the presence of antioxidants and other important nutrients such as fiber or vitamins. Although several studies have pointed to the influence of different environmental stresses in certain nutritional components little attention has been paid to the effect of the agroecological context on the nutritional properties of the seeds what may strongly impact on the consumer food’s quality. Thus, aiming to evaluate the effect of the agroecological conditions on the nutritional profile of quinoa seeds we analyzed three quinoa cultivars (Salcedo-INIA, Titicaca and Regalona) at different locations (Spain, Peru and Chile). The results revealed that several nutritional parameters such as the amino acid profile, the protein content, the mineral composition and the phytate amount in the seeds depend on the location and cultivar while other parameters such as saponin or fiber were more stable across locations. Our results support the notion that nutritional characteristics of seeds may be determined by seed’s origin and further analysis are needed to define the exact mechanisms that control the changes in the seeds nutritional properties.

<p>Nutritional composition of a composite sample of whole green crabs, <em>Carcinus maenas </em>(L.), was undertaken to evaluate efficacy as a forage fish replacement for seafood-meal manufacture. Whole green crabs sampled from New Hampshire waters were ground together and analyzed for proximate profile (moisture, lipid, protein, fiber, and ash), fatty acid profile, amino acid profile, mineral composition, and mercury content. Green crab mince contained 16.55 ± 0.29% ash, 12.27 ± 0.25% protein, and 0.21 ± 0.07% lipid, and comprised all amino acids essential for chickens and most species of fish. Fatty acid composition of ground green crab was 67.98% unsaturated, and 23.29% saturated, and was richer in eicosapentaenoic acid (EPA) than docosahexaenoic acid (DHA). Levels of mercury in green crab mince were below testable limits. The nutritional profile of green crab mince was evaluated relative to the nutritional profile of menhaden from the literature, and possible agrifeed applications for whole green crab were considered. Green crab showed great potential as a forage fish replacer in seafood-meal applications for chickens and ash tolerant species of fish.</p>

The nutritional composition and amino acid profile ofMoina macrocopawere studied using different types of yeast (Saccharomyces cerevisiaeandRhodotorula glutinis) as fodder substrates. The effective accumulation of carotenoids inMoina macrocopaduringR. glutinisyeast application was not accompanied by deterioration in the nutritional value of zooplankton. The content of total proteins and total lipids inMoinagrown onS. cerevisiaeandR. glutiniswas not significantly different. However, the use ofR. glutinisin the cultivation ofM. macrocopaled to the change in the ratio of proteinogenic amino acids in the studied cladocerans. In particular, the share of methionine, leucine and isoleucine significantly increased. It allowed to enhance the quality of protein in the fodder zooplankton, that is especially important in the feeding of fish fry.

Cookies, which form the largest category of bakery snacks, are considered a good vehicle to introduce nutrients into the diet. In this study, to increase the nutritional value of traditional commercial cookies, wheat flour was substituted with defatted flours made from flax, sesame, chia, and poppy, which are byproducts of the oil extraction industry. The differences in the technological properties, nutritional composition, and consumer acceptance of the reformulated cookies were evaluated. The results show that the wheat cookies used as the control showed a more elastic behavior than the cookies elaborated with defatted seed flours, which showed a greater tendency to crumble. The use of defatted seed flours yielded cookies with a higher content of protein and fiber, and a lower content in carbohydrates than the wheat cookies. Consumer evaluations for the sesame and flax cookies were similar to those for the traditional wheat cookies, with positive assessments on all of the parameters evaluated. On the other hand, the cookies elaborated using chia and poppy flours received the least positive evaluations from consumers. Thus, the use of some defatted seed flours, mainly flax and sesame, is proposed as an interesting alternative to produce health-promoting cookies in order to cover the current demand for gluten-free products.

Abstract Objective: This study aimed to characterise the availability, the nutritional composition and the processing degree of industrial foods for 0–36-month-old children according to the neighbourhoods affluence. Design: A cross-sectional exploratory study. Setting: All food products available in retail stores for children aged 0–36 months were analysed. Data collection took place in two neighbourhoods, comparing two different sociodemographic districts (high v. low per capita income), Campanhã and Foz do Douro in Porto, Portugal. Participants: A total of 431 commercially processed food products for children aged 0–36 months which are sold in 23 retail stores were identified. Food products were classified according to their processing degree using the NOVA Food Classification System. Results: For NOVA analysis, of the 244 food products that were included 82 (33·6 %) were minimally processed, 25 (10·2 %) processed and 137 (56·1 %) ultra processed. No food product was classified as a culinary ingredient. The products included mostly cereals, yogurts, prevailed in high-income neighbourhoods for the 0–6-month-old group. It was observed that some categories of ultra-processed food (UPF) presented higher amounts of energy, sugars, saturated fat and salt than unprocessed/minimally processed products. Conclusions: The high availability of UPF offered for 0–36-month-old children should be considered when designing interventions to promote a healthy diet in infancy.

Nutritional Components

In Vietnam, the giant mottle eel Anguilla marmorata is the most widely distributed species and being exploited for seed in aquaculture as well as for human consumption. This study aims to investigate the basic nutritional components of the fish. The eels were collected from six locations of Thua Thien Hue province, with weights from 5 to 3200 g. In addition, the content of lipid in skin and tissue was also examined. The results show that eel flesh has a relatively high nutritional value. The water, protein, lipid, and total sugar content of the fish meat is 60.4 ± 0.94%, 19.54 ± 4.31%, 18.2 ± 1.02%, and 1.34 ± 0.34 (mg/g), respectively. The nutritional components of the eel have a good correlation with the weight according to the equation: Y = a × ln (W) + b (where W is the weight of eels; Y is the content of nutritional components; a is the correlation coefficient b is a constant) with r > 0.9. The lipid content of the fish skin is higher than that of muscle and meat.
