The effects of fermentation on proximate and anti-nutrient compositions of Afzelia africana seed were investigated. Two methods of fermentation were employed; the traditional fermentation (TF) and gut-filtrate treated fermentation (GFTF). Anti-nutrients tested for were; alkaloids, phytate, tannins, saponins and flavonoids. All proximate contents varied significantly (P<0.05), except for ash. Afzelia africana fermented with cow gut filtrate poised the highest protein (19.35%), ash (4.20%) and lipid (32.13%) contents. The effects of cow gut filtrate fermentation on the nutritional status of A. Africana seed was only apparently (P>0.05) more pronounced than those of the natural fermentation. Fermentation significantly (P<0.05) increased the proximate nutrients except for nitrogen free extracts; which it reduced significantly. Fermentation also increased all anti-nutrients composition of the seeds except for phytate content. Fermentation significantly (P<0.05) enhanced crude protein by 30.45% for NF, 39.31% for GFTF and crude lipid by 77.64% for TF and 99.56% for GTFT. Thus fermenting Afzelia africana seed for aquaculture purpose is advocated for owing to its ability to enhance crude protein and crude lipid, not forgetting its medicinal potential due to its enhanced phytochemical levels.

The effects of various processing methods on the proximate composition and dieting ofAmaranthus hybridusandAmaranthus cruentusfrom West Cameroon were investigated in this study. Both amaranths leaves were subjected to same treatments (sun-dried and unsliced, sliced and cooked), milled, and analysed for their mineral and proximate composition. Thirty-SixWistaralbino rats of 21 to 24 days old were distributed in six groups and fed for 14 days with 10% protein based diets named D0 (protein-free diet), DI (egg white as reference protein), DII (sun-dried and unslicedA. hybridus), DIII (cooked and slicedA. hybridus), DIV (sun-dried and unslicedA. cruentus), and DV (cooked and slicedA. cruentus). The protein bioavailability and haematological and biochemical parameters were assessed in rats. The results showed that K, P, Mg, Zn, and Fe had the higher content in both samples regardless of processing method. The sun-dried and unslicedA. cruentuscontained the highest value of crude protein 32.22 g/100 g DM (dry matter) while the highest crude lipid, 3.80 and 2.58%, was observed, respectively, in sun-dried and unslicedA. hybridusand cooked and slicedA. cruentus. Cooked and slicedA. hybridusandA. cruentuscontained high crude fiber of 14 and 12.18%, respectively. Rats fed with diet DIII revealed the best protein bioavailability and haematological parameters whereas 100% mortality rate was recorded with group fed with diet DIV. From this study, it is evident that cooked and slicedA. hybridusandA. cruentuscould play a role in weight reduction regimes.

Phytochemical and nutritional potentials of various parts (leaf, stem and root) of Talinum triangulare were evaluated using standard techniques. Analysis of Variance (ANOVA) was employed in data analysis. All the parts of the species were found to contain nutrient compositions in varying levels. Dry matter and carbohydrate were highest in the stem (91.69±0.12 and 68.66±0.01) respectively. Moisture, ash content and crude fibre were highest in the root (9.78±0.04, 17.53±0.11and 15.32±0.03) respectively while ether extract and crude protein were highest in the leaf (1.09±0.01 and 17.72±0.17) respectively. The results showed also varying quantities of the phytochemicals in the leaf, stem and root with some parts lacking some of the phytochemicals. The leaf contained the highest percentage of all the phytochemical investigated alkaloid, flavonoid, tannin, sterol, Terpenoid, phenol and saponin (0.47±0.01, 0.26±0.00, 0.36±0.07, 0.03±0.01, 0.42±0.02, 0.02±0.01and 0.68±0.05 respectively. The root lacked sterol and phenol while stem lacked only phenol. The leaf, stem and root lacked cyanogenic glycoside. The results have indicated that these parts of the Talinum triangulare investigated are very nutritious and possessed bioactive compounds that could be extracted for the manufacture of new drug, food supplements and also be used in ethnomedicine for the treatment of diseases.

Globally, fermented beverage and condiments are made by using different conventional practices, raw materials, and microorganisms. This paper presents the available literature review on the technology and microbiology of traditional Ethiopian beverages and condiment products. Traditional fermented beverage and condiment products have essential vitamins, minerals, enzymes, and antioxidants that are all enhanced through the process of traditional fermentation practices. In Ethiopia, fermented beverage and condiment products have practiced in a long history. During the production of traditional fermented beverage and condiment products, controlled natural fermentation process with the absence of starter cultures are used to initiate it. Moreover, the preparation of many traditionally fermented beverage and condiment products is still practiced in a household art, thereby a wide variety of fermented beverages and condiments are consumed in Ethiopia. In conclusion, the review discusses the nature of the beverage and condiment preparation, poor traditional household processing, and the extent and limitation of scientific work done so far and suggests some recommendations to limit the problem in Ethiopia.

AbstractThis research focused on the effect of distant hybridization to improve the flesh quality of offspring from Oreochromis aurea (♀)×Siniperca chuatsi (♂). The proportions of different tissues and percentages of nutrient components were compared between fish of the F3 generation and O. aurea and S. chuatsi. The results showed that the proportion of flesh in F3 hybrids was significantly lower than that in O. aurea. Crude lipid content was lower and crude protein content significantly higher in the F3 generation. Concentrations of four kinds of amino acids important for flavour (DAA) were higher in the F3 generation than in O. aurea, and the total DAA was significantly higher. Furthermore, the other amino acid contents and essential amino acid index of the F3 generation were intermediate between O. aurea and S. chuatsi. We conclude that some effects of hybridization have induced flesh quality improvement.

AbstractIn a factorial design, animal fat was added incrementally (0, 35, 70 and 105 g/kg) to maize starch (M) or to two sources of fermentable carbohydrates (260 g purified cellulose (C) per kg or 270 g soya-bean hulls (S) per kg). The 12 experimental diets were formulated by replacing maize starch in the control diet with fat, cellulose and soya-bean hulls of equivalent estimated net energy. Ninety-six castrated males were given these diets according to net energy. Apparent digestibilities of crude protein, crude lipid, crude fibre and nitrogen-free extract were measured and were compared with those expected from the separate ingredients. Net energy conversion ratio (nECR) was also measured. Results showed that in the C and the S diets prediction of the apparent digestibility of nutrients was worse than in the M diets (significant effect of source of carbohydrate). Prediction of apparent digestibility of crude protein and crude lipid improved as the added fat increased (significant effect of amount of fat), except in the C and S diets where for digestible crude lipid the 70 g added fat per kg gave the worst prediction (significant effect of the interaction). The net energy calculated from the experimental data on apparent digestibility was proportionately between 0·83 and 0·98 of that calculated from the expected data. The pigs on the C and S treatments showed a significant lower nECR when calculated from the expected apparent digestibility coefficients, but not when calculated from those which were measured. At the highest fat addition, the nECR was poorest. It is concluded that the amounts of digestible components in compound foods cannot always be obtained from those in the separate ingredients.

The coefficients of the apparent digestibility for dry matter, crude protein, crude lipid and gross energy in cooked and raw green plantain meal (GPM), cassava root meal (CRM), and peach palm meal (PPM) were determined for juveniles of black pacu (60.8 ± 6.4 g) and red pacu (76.3 ± 5.0 g). The ADC of each alternative ingredient was determined by comparison of the digestibility (based on recovery of 1% chromic oxide as an inert marker) of a reference diet (consisting of 70% of test diet and 30% of the feedstuff) against with a test diet (24.5% of crude protein). Fish were bred in a recirculation system including 42, 110-L glass aquaria (21 tanks per species) at a density of five fish per tank, and fed their respective diets to apparent satiety, twice a day. Feces were collected after 10 days in plexiglass fecal collectors. Apparent digestibility coefficients of crude protein, crude lipid and gross energy from raw and cooked GPM and CRM were low compared to values to other common vegetal ingredients like corn and wheat. Conversely, ADC values for raw and cooked PPM were, in most cases, higher than those reported in raw or cooked GPM and CRM. In comparison with other traditional feedstuffs, apparent utilization of PPM was similar to corn and higher than reported for soybean meal and wheat bran in these fish species. Peach palm meal appears to have good potential as a feed ingredient in low-cost diets for pacu species.

Caulerpa lentillifera is an edible and functional seaweed due to its high nutritional compositions and its biological activities.  In this study, C. lentillifera was evaluated for its proximate compositions (moisture, ash, protein, lipid and fiber contents) and its biological activities (antimicrobial, anti-oxidant, and toxicity). Moisture content, crude lipid, crude protein, and crude fiber were determined using oven method, soxhlet extraction, semi-micro Kjeldhal, and hydrolysis, respectively.  Fresh C. lentillifera of Natuna Island, Indonesia, showed its higher level content of ash, crude lipid, and crude fiber compared to that of fresh C. lentillifera of Penghu, Taiwan.  For its biological activity assays, the extracts were prepared from fresh and dry C. lentillifera (FC and DC).  Both of the extracts showed the broad spectrum of weak antimicrobial using well-diffusion agar tests and antioxidant activities using a modified linoleic acid emulsion system.  The toxicity for both extracts was determined using brine shrimp lethality test.  DC extract showed its very low toxicity level and there was no toxicity for FC.  Hemolytic activity was determined using red blood assay.  Both extracts showed their low hemolytic activities (about 5-13%) for the concentration of 100 and 150 μg/mL, but the activity increased sharply (about 96%) on the concentration of 200 μg/mL.  It was concluded that C. lentillifera has a potency as a functional food due to containing secondary metabolites with various biological activities.

The aim of this study was to determine crude protein, fibre and phytic acid in vitro digestibility of selected legumes and buckwheat products. All analyses except the phytic acid contents were performed in the line with the Commission Regulation (EC) No. 152/2009. A modified version of Holt’s Method was used for phytic acid (phytate) determination. None of all samples contained more than 11% of moisture. Soybeans are rich in crude protein; they contain nearly 40% of this compound. The content of crude protein in buckwheat flours was about 14%. The highest amount of phytate was found in common beans and soybeans-about 2 g/100 g of dry matter. On the other hand, the lowest phytate content was observed in buckwheat pasta (< 1 g/100 g). The quantification of phytate in F. esculentum groats was 1.9 g per 100 g of dry matter. In vitro digestibility was determined using an incubator Daisy and pepsin enzymes and the combination of pepsin and pancreatin. The highest coefficient of crude protein digestibility was discovered to be in peels and wholemeal flour. The greatest fibre digestibility coefficients were obtained for peels, which contain about 65% of fibre in their dry matter. When pepsin was used, a higher phytic acid digestibility coefficient for G. max, Ph. vulgaris, peels, flour, groats and broken groats was observed; while when the combination of pepsin and pancreatin was used, higher phytic acid digestibility coefficients for peas, lentil and wholemeal flour were observed.

In this paper, a mathematical model was used to evaluate a dynamical hybrid system for optimizing and controlling the efficacy of plant-based protein in aquafeeds. Fishmeal (FM), raw rapeseed meal (RM), and a fermented meal with yeast (RM-Yeast) and fungi (Aspergillus oryzae RM-Koji) were used as test ingredients for the determination of apparent digestibility coefficients (ADCs) of dry matter, crude protein, crude lipid, energy, and essential amino acids (EAA) for olive flounder (Paralichthys olivaceus, 7 ± 0.02 g) using diets containing 0.5% Cr2O3 as an inert indicator. Among all ingredients tested, FM had the maximum ADC of dry matter ( P < 0.05 ), protein ( P < 0.05 ), lipid ( P > 0.05 ), and energy ( P > 0.05 ). Fermented meals (RM-Yeast and RM-Koji) showed higher ADC ( P < 0.05 ) of crude protein compared with RM, while there was no significance in ADCs of crude lipid and energy among different forms of rapeseed meal. Besides, ADC of crude lipid for RM-Yeast and RM-Koji, on the one hand, and ADC of gross energy for RM-Yeast, on the other hand, were not varied from that for FM ( P > 0.05 ). Amino acid digestibility reflects protein digestibility in most cases. Interestingly, protease, lipase, and amylase activities were better expressed in RM-Koji, RM-Yeast, and FM over RM, respectively. The current results deliver important information on nutrients and energy bioavailability in raw and fermented RM, which can be implemented to accurately formulate applied feeds for olive flounder. Compared with other applicable systems, the complexity of the approach implemented has been considerably reduced.
