Chin-Chin, a traditional Nigerian snack was prepared utilizing wheat-fermented maize residue composite flour at 0 – 30% replacement levels. Effects of this addition on the functional and pasting properties of the flour composite was evaluated. The snack produced was also evaluated for its sensory attributes, proximate composition and invitro-protein digestibility (IVPD). Functional properties results showed an increase in water absorption capacity (WAC), a decrease in oil absorption capacity (OAC), decrease in Bulk Density (BD), swelling power and solubility index with residue addition. Pasting property results showed a drop in the value of peak, trough, breakdown and final viscosity with substitution while set back viscosity increased.Peak temperature decreased, but values for pasting temperature showed no significant difference between the control and the blends. Results for sensory evaluation showed equal preference for overall acceptability. Proximate composition results showed residue addition led to an increase in crude fibre and protein content with a drop in the carbohydrate value. Residue addition did not increase protein digestibility. Addition of fermented maize residue in chin-chin production can be another way of utilizing the fibre rich by-product of the production of fermented maize starch.

The proximate and mineral constituents of six plantain forms, raw green plantain (RGP), cooked green plantain (CGP), raw ripe plantain (RRP), cooked ripe plantain (CRP), green plantain meal (GPM) and ripe plantain meal (RPM) were determined by chemical analysis. 24 large white barrows, weighing initially, between 40-45 kg., were used to study the apparent digestibility of nutrients, digestible energy (DE), metabolizable energy (ME), metabolizable energy corrected for nitrogen retention (ME(n) and total digestible nutrients when the plantains served as the only source of nutrients. In a second experiment ME and ME(n) were measured for the plantain forms using 28 Large White barrows, with diets in which the plantains replaced 50% of maize in a basal diet. All the plantain forms had low fat, crude fibre and crude protein content but high in nitrogen-free extract, phosphorus, potassium and Iron. Identically high dry matter (D.M.) and nitrogen-free extract (N.F.E.) digestion coefficients were obtained for all the plantain forms except RPM, which had significantly lower values. Digestion coefficients for crude protein (46.9, 53.6, 51.8, 34.3,-32.7 %), crude fibre, (46.6, 49.5, 58.7, 62.6, 56.9, 39.6 %), ether extract (55.9, 56.6, 66.9, 69.2, 54.7 and 34.6 %) for RGP, CGP, RRP, CRP, GPM and RPM respectively were considerably lower than for D.M. and N.F.E. The DE, ME ME(n) and TDN values were comparable for all plantain forms except RPM, which had significantly lower values in most cases. The fresh green plantains and green plantain meals had slightly higher energy values than the ripe plantains, even though the nutrients in the ripe plantains were better digested than in the green forms. The results are discussed in relation to variations in the relative proportions of the simple and more complex carbohydrates during ripening.

The present study was undertaken to evaluate the effect of different levels of corn flour on the quality characteristics of chicken meatball. The meatballs were formulated having 0, 05, 10 and 15% of corn flour. After formulation, samples were preserved at -20˚C for 60 days and analyzed the data at 0, 15, 30 and 60th day, respectively. The products were analyzed for various sensory, proximate, biochemical and physicochemical attributes. The sensory (color, flavor, tenderness, juiciness and overall acceptability), proximate composition- dry matter (DM), ether extract (EE), crude protein (CP) and ash, biochemical parameters- free fatty acid (FFA), peroxide value (PV) and thiobarbituric acid value (TBARS) and physicochemical (raw pH, cooked pH and cooking loss) were analyzed. Data were analyzed in a 4x4 factorial experiment in completely randomized design with replicated three times per cell. Results showed that corn flour inclusion in meatballs have no effect on sensory parameters, but the highest value for all sensory parameters was found at 15th day storage period, (p<0.05). After 15th day, with the increasing of storage period the value for all sensory parameters were decreased (p<0.05). The proximate component’s value were differ with treatment and day interval group (p<0.05). The highest value of raw pH and lowest value of cooking loss were found in 5% corn flour group (p<0.05). The highest value of cooked pH and lowest value of cooking loss were found at 15th day storage period. There were no effect of treatment or day interval on FFA and TBARS. Highest value of PV were found in 0% cornflower group (p<0.05). It may be concluded that 5% corn flour and 15 days storage period is suitable for chicken meat ball.Bang. J. Anim.

The aim of the current study was to find out the effect of adding different levels of lemon extract to the chicken meatballs. Fresh lemon extract was incorporated into freshly prepared meatball and compared with 0.01 % beta hydroxyl toluene (BHT) and control (without antioxidant). For this purpose, chicken meatball samples were divided into four treatment groups; viz. T0 (Control), T1 (0.01% BHT), T2 (0.5 % lemon extract) and T3 (1 % lemon extract). The study was conducted in completely randomized factorial design. The samples were analyzed for determination of sensory, proximate components, physicochemical, biochemical and microbiological qualities at 0, 30th and 90th days of preservation. Color, flavor, Juiciness, tenderness and overall acceptability increased significantly (p<0.05) among different treatment groups than control and BHT group but decreased at different days of intervals. Dry matter (DM) content decreased significantly (p<0.05) with different treatment levels than control and BHT group and increased with days of intervals. Crude protein (CP), ether extract (EE) and Ash of all treatments were decreased significantly (p<0.05) among different treatment groups. Raw pH, cooked pH and cooking loss were decreased significantly (p<0.05) with different treatment levels than control and BHT group and decreased with days of intervals. Free fatty acid (FFA), peroxide value (POV) and thiobarbituric acid reactive substances (TBARS) value were decreased significantly (p<0.05) with different treatment levels than that of control and BHT group and increased with days of intervals. Total viable count (TVC), total coli form count (TCC) and total yeast mould count (TYMC) decreased significantly (p<0.05) at different treatment levels than that of control and BHT group. Therefore, it can be concluded that 1 % lemon extract for formulation of value-added chicken meatballs was enriched source as natural antioxidant. SAARC J. Agri., 18(2): 139-156 (2020)

Aim: The aim was to evaluate the chemical, physical, sensory and microbial qualities of fruit bars produced from blends of banana and cashew apple fruits and to investigate the applicability of cashew apple in fruit bar production. Study Design: The experimental design used was the complete randomized design (CRD) and the data obtained were analyzed using one – way analysis of variance (ANOVA). Place and duration of Study: The study took place at the Department of Food Science and Technology, University of Nigeria, Nsukka between January and July, 2016. Methodology: Fruit bar samples were prepared with blends of  ripe banana and cashew apple purees in the ratios of 90:10, 80:20, 70:30, 60:40, 50: 50% (Banana puree : Cashew apple puree). One hundred percent (100%) banana pulp based fruit bar served as the control. Formulated fruit bars contained 7% sugar, 5% date powder, 0.2% sodium metabisulphite and 0.5% citric acid in 1000 g of fruit purees and dried at 80oC for 8 hours. Fruit bar samples were analysed for sensory qualities, proximate composition, micronutrient compositions (vitamin C and potassium), physicochemical properties (pH, brix and titratable acidiy), and microbiological quality using standard methods. Results: There were significant (p<0.05) differences in the proximate composition, potassium, vitamin C and tannin content of samples. The carbohydrate, protein, crude fibre, ash and moisture contents ranged from 68.78 to 74.51%, 3.06 to 3.38%, 1.00 to 2.05%, 2.33 to 2.76% and 18.92 to 22.64% respectively. The fruit bars have high caloric energy values. The vitamin C content increased as the ratio of cashew apple increased. Potassium and tannin contents of the samples ranged from 125.50 to 220.00mg/100g and 52.04 to 84.23 mg/100g respectively. Titratable acidity, pH and brix of samples varied significantly (p < 0.05) and ranged from 0.23 to 0.37%, 4.00 to 4.65% and 7.10 to 11.85% respectively. The microbial results showed that total viable count found present in the fruit bar samples ranged from 4.0 x 102 to 1.3 x 103 while the mould count ranged from 2.0 x 101 to 7.0 x 101. The sensory scores showed that all samples were generally accepted while the sample with 20% of cashew apple was the most preferred. These results showed that underutilized fruits such as cashew apple can be utilized in this regard instead of being wasted.

PurposeThis study aims to investigate the effects of incorporating seaweed composite flour on soft roll dough rheological characteristics and quality.Design/methodology/approachIn this study, wheat flour was substituted with seaweed powder obtained from red seaweed (Kappaphycus alvarezii) at varying proportions (100:0; 99:1; 98:2; 97:3; 96:4; 95:5, 94:6, 93:7 and 92:8) and applied in soft roll production. The effects of seaweed composite flour were evaluated in terms of rheological characteristics, proximate composition and physical properties. The sensory characteristics of the soft rolls was evaluated by 40 untrained panellists by using a hedonic scale.FindingsFarinograph analysis of the soft roll doughs showed that the incorporation of seaweed powder promoted an increase in water absorption, development time and mixing tolerance index, whereas it decreased stability time. Analysis of the proximate composition of the soft rolls showed that protein and carbohydrate contents decreased, but moisture, ash and crude fibre contents substantially increased. Dietary fibre increased with the increase in the proportion of seaweed powder added. The specific volume, bulk density and firmness of the soft rolls ranged from 3.01 to 5.48 cm3/g, 0.18 to 0.33 g/cm3 and 1.86 to 20.63 N, respectively. Sensory evaluation results showed that the mean score of sensory attributes decreased as the proportion of seaweed powder added was increased in the formulations. With regard to the overall acceptability, the panellists preferred the soft rolls with the least amount of seaweed powder added. The results of hedonic tests revealed that the panellists' acceptance decreased as higher amounts seaweed powder were added in the formulations.Originality/valueThis study showed that the seaweed powder of K. alvarezii can be utilised as an ingredient to improve the nutrient composition of baked products.

Storage stability of raw chevon (goat meat) chunks wrapped in preformed, bioactive, biodegradable films based on composite starch–chitosan and impregnated with nisin (60 000 IU/g; T-1) and cinnamaldehyde (0.5% v/v; T-2) was evaluated relative to unwrapped product (control) under aerobic refrigeration (4°C ± 1°C) conditions for 10 days. Samples were taken on Days 1, 4, 7 and 10 to assess various physicochemical, microbiological and sensory quality parameters. Water activity and pH of raw chevon chunks followed a decreasing trend during storage under all packaging conditions; the rate of decrease of water activity was higher (P < 0.05) in the control than in bio-packaged products. Values of thiobarbituric acid reactive substances increased throughout storage and were lowest in T-2 and highest in the control. Extract release volume decreased throughout storage under all packaging conditions; however, it was higher (P < 0.05) in bio-packaged products than the control. Microbial quality was better in bio-packaged products than the control throughout storage. Standard plate count was 2.09 log10 cycles lower in T-2 than the control, and coliform count was lower by log10 2.31 cfu/g in T-2 and log10 1.88 in T-1 than the control on Day 7 of storage. Staphylococcus counts were lower (P < 0.05) in bioactive-packaged products than the control throughout the storage period. Sensory quality attributes colour, odour, texture and overall acceptability were better maintained in bio-packaged products than the control during storage, and maximum scores were awarded to T-2. The results indicate that starch–chitosan composite films impregnated with cinnamaldehyde can be used for the packaging of raw goat meat and successfully extend storage life by inhibiting the colour, oxidative and microbial deteriorative changes under refrigeration.
