Aim: The study was conducted to determine the effect of fermented finger millet flour supplementation in wheat on the physical and sensory properties of bread.

Methodology: Finger millet grains were cleaned, washed and fermented in deionized water for 72 h at room temperature (27±2oC), with sampling at every 24 h interval. Fermented grains were washed, drained, dried (65oC, 4 h), milled and sieved (<250 µm) to produce Fermented Finger Millet Flour (FFMF). Composite flour was formulated by supplementing wheat flour with Fermented Finger Millet Flour (FFMF) at 0, 5, 10, 15 and 20 % (w/w), and used to produce bread samples. Physical (Oven spring, loaf weight, loaf volume and specific volume) and sensory (crust colour, crumb colour, aroma, texture, taste, mouth feel and overall acceptability) properties of the bread samples were determined.

Results: Physical properties showed less oven spring, loaf volume and specific loaf volume and increased loaf weight with increased FFMF replacement. The sensory analysis showed significant differences (p<0.05) between 100% wheat bread and FFMF supplemented samples in all the determined sensory properties. It was concluded that fermentation period of 24-48 h, and substitution of 5-10% FFMF into wheat gave the bread samples with the best overall acceptability.

Aims: The present work is part of a sanitary quality control of market garden products in Korhogo. The objective of this study was to know the microbiological quality of tomatoes (Solanum lycopersicum L.) sold on the markets of the city of Korhogo.

Place and Duration of Study: The analyses were carried out at the microbiology laboratory of Peleforo Gon Coulibaly University during the months of October, November and December 2020.

Methodology: Germs such as molds, yeasts, mesophilic aerobic germs, total coliforms, Staphylococcus aureus, Escherichia coli and Clostridium were tested and enumerated on 40 tomato samples from the markets of Haoussabougou, Koko, Sinistré and the big market according to conventional microbiology methods.

Results: The average loads of molds and yeasts range from 1.2x104 to 6x105 CFU/g. The average loads of mesophilic aerobic germs vary from 2.3x104 to 2.3x105 CFU/g. The highest loads recorded for Staphylococcus aureus and total coliforms were 3.1x104 CFU/g and 1.5x104 CFU/g respectively. Escherichia coli (4x101 CFU/g) was isolated only from tomatoes collected in Haoussabougou. As for the Clostridium genus, it was not detected on all the tomatoes analyzed.

Conclusion: In general, the microbial loads of the analyzed samples are higher than the accepted norm. Thus, the tomatoes sold on the markets of the city of Korhogo have an unsatisfactory microbiological quality. It is advisable to clean, disinfect and rinse these tomatoes carefully with drinking water before consuming them raw.

Aims: Sri Lankan tea which is known as the Ceylon tea is the world’s finest tea. Currently Sri Lanka remains as the second main black tea (BT) exporter and the main orthodox BT exporter in the world. Although several pharmacological activities of Ceylon tea have been reported, its anti-acetylcholinesterase (AChE) activity which has a direct relationship with the management of Alzheimer's disease or type 3 diabetes has not reported to date. Further, there are no comprehensive studies on anti-AChE activity of tea world over. Present study evaluated anti-AChE activity of commercially important Ceylon BT grades belonging to different elevations.

Methodology: Freeze dried hot water extracts of Broken Orange Pekoe Fannings (BOPF), Orange Pekoe (OP) and Dust No.1 BT grades from low, mid and high grown elevations and a Ceylon green tea sample collected from the local market were studied for anti-AChE activity using 96 well micro plate-based assay (n=3 each).

Results: Results showed that all tested Ceylon tea had anti-AChE activity with varying degrees of potentials in a dose dependent manner. The mean IC50 values of BOPF, OP and Dust No. 1 tea grades at different elevations varied from 499.61±10.95 - 569.19±5.78, 598.80±24.95 - 677.81±6.61 and 509.44±3.81 - 621.39±3.29 µg/mL respectively. Interestingly, observed anti-AChE activity of black tea showed significant differences (P< 0.05) among elevations. The order of potency of BOPF, OP and Dust No:1 BT for anti-AChE activity at different elevations was low grown>high grown=mid grown, high grown=low grown>mid grown and mid grown>low grown>high grown respectively. Anti-AChE activity of Ceylon green (433.96 ± 5.95 µg/mL) tea was significantly high (P<0.05) compared to the tested BT and activities of all Ceylon tea were moderate compared to the reference standard Galantamine (IC50:2.52±0.17 µg/mL).

Conclusion: It is concluded that selected Ceylon BT grades had varying levels of anti-AChE activity and it varied with the elevations.

The research work is done to evaluate the effect of temperature on drying characteristics and quality of red, cream and white varieties Nigerian onion using a locally fabricated electrically powered dryer. Clean onion samples of 1.5 kg from each of the three varieties were sliced into 3 mm thickness. Fresh samples of the three onion varieties were analyzed to determine the initial values of protein, fat, ash, crude fibre, and moisture content on a dried basis (m.c.d.b.) using recommended AOAC methods.. Vitamin C and microbial loads content were determined before loading into a locally fabricated electrically-powered dryer. The onion samples were dried at varying pre-determined temperatures of 50, 60, and 70 oC. After drying, the proximate compositions, vitamin C and microbial loads were also determined. The protein, fat, ash and crude fibre of the fresh onion samples were 1.5, 0.5, 0.6 and 0.5%, respectively, while m.c.d.b, vitamin C content and microbial loads ranged from 85.1-88.2%, 8.1-8.3 mg/100 gm and 4.45-5.39 mg. Red onion samples were dried for 13:15h, 12:10h and 10:30h; white onion samples for 13:00h, 12:25h and 10:40h; while cream onion samples for 13:10h, 12:35h and 10:15h at 50, 60, and 70 oC, respectively. The protein, fat, ash, crude fibre, m.c.d.b, vitamin C content and microbial loads of the dried onion samples at all the drying temperatures ranged from 10.110.4, 1.1-1.5, 3.3-3.5, 5.5-5.8, 5.5-6.9%, 3.1-4.9 mg/100 gm, 1.314.17 mg, respectively. The drying temperature had a significant effect (p-value < 0.05) on the quality of all the onion samples. At 70 oC, protein, fibre, ash, fat and pungency retention were significantly (p< 0.05) high and within acceptable limits while microbial loads were low with the reduction in Vitamin C contents in all the onion varieties. Therefore, onion can best be dried at 70 oC to achieve the optimum quality and flavour required for its use as a spice.

Kokoro, a maize-based snack was made from maize flour and supplemented with Moringa
seed flour (MSS) and defatted sesame flour (DSF) flours with the aim of improving its nutritional quality. An experimental design was carried out using optimal mixture model of response surface methodology which yielded 16 formulations in which three blends in terms of the best proximate composition and the control sample (100% maize) were selected. The snacks were analyzed for proximate, mineral, amino acid composition, sensory and antioxidant properties. Proximate analysis results showed significant (p<0.05) increase in protein (9.25–24.23%), fat (15.07–35.25%), ash (2.25–4.25%) content, and energy value (508.43–607.71 KJ/ g), while crude fiber (7.58–5.80%), moisture (4.58-3.64%) and carbohydrate (61.27–26.83%) content decreased with inclusion of MSF and DSF. Potassium (4.02-5.03mg/100 g) was the predominant mineral, followed by calcium (3.31-5.41mg/100 g) and potassium (1.67-3.75mg/100 g). Glutamic acid was the most abundant non–essential amino acids while leucine was the predominant essential amino acid in the enriched kokoro. There was an increase in the amino acid content (except for aspartic acid, arginine and histidine) of the kokoro samples as the proportions of MSF and DSF increased. The result also showed that the essential amino acid index, predicted biological value, protein efficiency ratio and nutritional index of the enriched kokoro were higher than the control sample with values ranging from 0.6108-0.8944, 54.88-85.79%, 1.63-3.49g/100g and 5.65-21.67%, respectively. The result also showed that there was a significant (p<0.05) increase in the flavonoid, phenolic content and DPPH of the kokoro as supplementation with MSF and DSF increased. The control sample compared favourably with kokoro supplemented with 6.25% and 17.5% MSF and DSF, respectively, in terms of sensory evaluation. Hence, acceptable and nutritious kokoro snacks from this blend can be formulated which could enhance the nutritional wellness of consumers.

DOI: 10.9734/afsj/2021/v20i1030368

Valid and reliable questionnaires are necessary to improve the existence and quality of nutrition information, which determines interventions in low-resource settings, especially among decision makers and change agents.

The present study evaluated the internal consistency and test-retest reliability of the data collected among 255 head teachers from schools in Mukono and Wakiso districts in Uganda using a general nutrition knowledge questionnaire (GNKQ) earlier developed. Cronbach alpha (α) was used to determine internal consistency. Pearson's correlation coefficient (r) and intraclass correlation coefficient were used to measure test-retest dependability on scores (ICC2,1).

Overall internal consistency on 94 items was α = 0.89 at time one and 0.92 at time two. All items yielded data with a satisfactory internal consistency (α > 0.7). Two domains, Expert advice (ICC = 0.64) and Selecting food (ICC = 0.41), were determined to have insufficient test-retest reliability (r < 0.7 and ICC = 0.7), and their items were removed from the next analyses. The remaining nutrition knowledge topics with adequate test-retest reliability were food groupings (ICC = 0.9), nutrition and sickness (ICC = 0.91), and food fortification (ICC = 0.95). According to the findings, the prototype nutrition knowledge questionnaire had acceptable internal consistency and test-retest reliability.

These findings indicate that the previously established questionnaire can be used to assess general nutrition knowledge among head teachers. To boost generalizability, future studies could use the questionnaire on a different group of adults.

Robert Mugabi

Asian Food Science Journal, Volume 20, Issue 10, Page 137-144
DOI: 10.9734/afsj/2021/v20i1030369

Introduction: Particle size is one of the main variables that influence coffee brewing process and also most obvious to the consumers. The aim of this study was to evaluate the effect of different particle sizes on the color of ground coffee.

Methods: A laser diffraction analyzer was used to determine the particle size distribution of the 14 dry ground coffee samples. The particle size distribution of the roasted ground coffee samples that underwent grinding at different time periods was based on volume distribution. Color measurements of all coffee samples were made using a portable CR-400 tristimulus colorimeter and Spectra-Match software, set to L*, a*, b* mode. Color measurements were recorded for two replicates of each sample.

Results: Coffee samples ground for short times of 30s, 20s and 10s, were observed to have coarser particles than those that underwent longer grinding times. The 20s and 30s grinding times did not exhibit any significant differences for the D50 and D90 particle size distributions. There was no significant difference in D50 and D90 values for Colombian 1.3, Leyenda and Tarrazu brands. It was observed that lightness (L*) as well as a* and b* were highly significantly different between the different coffee samples with P < 0.0001. The coffee samples that underwent grinding for 60s had the highest L*, a* and b* values of 30.72, +1.31 and +1.39 respectively. Colombian 1.3 coffee brand had the lowest L* and a* values of 29.8 and +0.67 respectively, with brand 1820a having the lowest b* value of +0.39.

Conclusion: The results of this study show that there was no significant effect of particle size distribution of coffee samples on color of the ground coffee particles. L*, a* and b* values decreased during roasting, due to the darkening of the beans resulting from sugar caramelization and Maillard reactions.

Cassava occupies an important place in the food security of populations in Côte d'Ivoire. There are many products derived from cassava but«attiéké» remains the flagship product in Côte d'Ivoire. Faced with the productivity challenges, organic fertilization is increasingly used by farmers in order to sustainably increase cassava production. The perspective of our study is to assess the effects of the uncombined use of cowpea and poultry manure as organic soil fertilizers on certain physicochemical and sensory characteristics of «attiékés» of three varieties of cassava. To do this, on an experimental plot installed, cowpea fertilization was tested at planting densities of 62,500; 250,000 and 125,000 plants/ha and poultry manure at rates 5; 15 and 5 t/haon, respectively, the cassava varieties Yavo, BoCou1 and Yacé.The results obtained show that cowpea and poultry manure increased the dry matter content respectively by 3.99 and 3.53 % in the Yavo variety by 3.57 and 18.06 % in the BoCou 1 as well as by 17.43 and 17.64 % in the Yacé. For the other parameters of pH, titratable acidity, total carbohydrates and free glucose, the variations depended on the variety and the level of fertilization. The sensory attributes of attiekes from these varieties grown on fertilized soil have been accepted by consumers in terms of color, smell, taste and consistency. In addition, they were rated less good than the controls obtained without fertilizer due to color, taste and consistency, while in terms of odor, it would be the same rating.

Oats are known to be a healthy food for the heart mainly due to their high β-glucan content. Besides, they contain more than 20 unique polyphenols, avenanthramides, which have shown strong antioxidant activity in vitro and in vivo. The polyphenols of oats have also recently been shown to exhibit anti-inflammatory, anti-proliferative, and anti-itching activity, which may provide additional protection against coronary heart disease, colon cancer, and skin irritation. Oats have been labelled as a functional food as they contain β-glucan, minerals, and antioxidants. Owing to their high nutritional value, oat-based food products like bread, biscuits, cookies, probiotic drinks, breakfast cereals, flakes, and infant food are gaining increasing consideration.
