Purpose: The study was carried out to evaluate the proximate, rheological and sensory properties of Millet based salad cream in comparison with the conventional salad cream. Methodology: Starches were extracted from four different local varieties of millet, comprising two varieties of pearl millet, namely Gero and Maiwa (Pennisetum glaucum), Tamba-Finger millet (Eluesine coracona) and Acha-Fonio millet (Digitaria exillis) using dry and wet milling processes for the purpose of making salad cream. Standard analytical methods were used in measuring the pH values, proximate composition and viscosity. A 9-point Hedonic scale was used to evaluate the sensory characteristics of the salad cream. Findings: Values obtained for pH varied between 3.10 and 3.62 while the sample used as control had a pH of 3.07. Millet starch-based salad cream as well as the control sample had moisture content above 40 %, while protein and fat content ranged from 1.90 % to 4.49 % and 24.41 % to 33.74 % respectively. The control sample had protein content of 4.11% and fat content of 31.89 % in that order. Total available carbohydrate was highest in the samples tested (18.38 %) and 15.33 % in the control sample. Ash content was significantly (p < 0.05) different in the samples and the control; sample values ranged from 1.38 to1.81 % while the control was 1.29 %. Fibre was not detected in all the samples including control sample. Meanwhile, there was significant (p<0.05) difference in Energy (Kcal) and Energy (KJ) in the Millet starch based salad cream and the sample used as control with Millet starch based salad cream having Energy (Kcal) and Energy (KJ) in the range of 287.19 to 331.88 Kcal and 1190.0 to 1374.2 KJ respectively. The control sample had 364.77 and 1510.4 Energy (Kcal/KJ). The viscosity of dry and wet milled millet starch-based salad cream ranged from 0.006-0.033 mls. The control sample value was 0.006 and 0.004mls respectively. All salad cream samples exhibited a non-Newtonian behaviour. Sensory analysis result showed no significant (p >0.05) difference in colour, taste, texture among Millet starch based salad cream, however, there was significant (p < 0.05) difference in the colour, taste, texture attributes in the control sample. .The mean scores of colours, appearance, flavour, taste, mouth feel, texture and overall acceptability of the salad cream samples prepared from the four different local varieties of millet starches compared with a commercial salad cream shows Colour range of 4.30 – 8.50. Appearance ranged from 3.13 – 8.10. Sample Wmg had the least score of 5.00 in the taste attribute while the highest value was observed in Wmm (8.16). Highest score for Mouthfeel was observed in Wmm sample (7.43) with Wmg having the least score of (5.40). Average score for texture range from 4.80 to 7.53. The sample Wmm had the highest value (7.87) for Overall acceptability while Wma had the least value of 5.11. Sample Wmm (wet milled Maiwa) was preferred by the Panellist over the control sample, this means that comparable salad cream can successfully be produced from Millet based starch.

Purpose: The study was carried out to evaluate the physico-chemical properties of starches from four local varieties of millet in salad cream production. Methodology: Starches were extracted from four varieties of millet, two varieties of pearl millet were used namely Gero and Maiwa (Pennisetum glaucum), Tamba-Finger millet (Eluesine coracona) and Acha-Fonio millet (Digitaria exillis) using dry and wet milling processes for characterization and salad cream production. Standard analytical methods were used in determining the physicochemical properties of the starches. Findings: The various starches physical properties, including colour, Amylose, Amylopectin, Starch Damage and Total Starch of millet cultivars were determined, and significant (p < 0.05) differences were observed among them. Values obtained for Amylose and amylopectin ranged from 24.47 to 26.91% and 73.09 to 74.51% respectively. The amount of starch damage varied from 0.08 to 0.10 % while total starch contained in the various samples ranged from 89.74 to 98.42 %.  Proximate composition showed no significant difference among the starches in terms of moisture except in the wet milled Acha with 10 %. Ash content of the starches ranged between 0.79 and 9.22 %.  Fat was higher in the control sample 10.22 % and lowest in the wet milled Tamba 1.69 %. Significant differences P<0.005 were found in the protein content amongst the various starches extracted, with Wmg having the highest value of 9.26 %. Crude fibre was in the range of 2.37 and 4.50 %. The Resistant starch was highest in Wmt (79.44%) and lowest in Dma (16.90%). Carbohydrate content was less in the control sample Wmc (62.40%) and highest in Wma (75.29%). Functional properties of various starches such as Bulk density ranged from 0.59% to 0.77%. Water absorption capacity of the starches were between 0.35% and 4.80% with Dmm starch having the lowest and Wmg the highest. Oil absorption capacity of starches varied between 2.10g/ml and 2.80g/ml. while swelling power were 0.43 to 0.91% with Dmc starch recording the lowest and Dmg starch the highest. Solubility values ranged from 9.50 to 24.00% with Dmm and Dmg having lowest and highest respectively. Least gelation capacity varied from 6% to 10%. The pasting characteristics of the four different starches were significantly (p < .05) different. Peak viscosity ranged from 2145.5 to 4379.0 RVU while Trough viscosity ranged from 1311.0 to 3190.0 RVU. Breakdown viscosity ranged from 625.5 RVU to 2401.5 RVU. The Final viscosity varied between 2704.5 and 5495.0 RVU. Increase may be attributed to high carbohydrate content in the different starches. Setback viscosity in this study ranged from 1393.5 to 2633.0 RVU. Peak time measured the peak viscosities in minutes of the cooking time of the starches and it ranged from 4.93 min to 6.30 min. Pasting temperature varied between 75.85°C and 88.40°C. Starches produced from the four local Millet varieties can be utilized for making diverse food products to meet the growing demand for starches in the food industries.

The world is tending towards fortification of cereal, root and tubers food products to increase and enhance its macro and micronutrients content for her teaming population. This study investigated the quality and sensory evaluation of spaghetti produced from plantain and wheat flour blends. The dried plantain chips were milled, sieved to pass through sieve number 60 BS and blends with wheat flour at levels of 100:00%, 85:15%, 80:20%, 75:25%, 70:30%, respectively. The five samples formulated were analyzed for nutritional properties and sensory attributes using a 9-point hedonic scale of preference. All data were subjected to analysis of variance while significant differences were determined at p<0.05, while Duncan multiple range test was used to separate the mean. The study finding shows that nutritionally improved spaghetti products could be produced from mixture of plantain and wheat flour within the range of 15% - 25% wheat flour substitution. The mineral profiles of the study show improvement in quality and quantity compare to the control sample. However, iron, sodium and zinc content of the spaghetti samples were far below recommended daily allowance, hence there is need to supplement such food with fruit- vegetables. The high mean score obtained for the overall acceptability showed that the plantain-based spaghetti samples were accepted by the panellists. Sample with 20% wheat flour substitution level had the highest mean score (6.77) than other wheat flour substituted samples. This might be the perfect blend to make spaghetti from plantainwheat flour blends.

The nutrient and sensory properties of malted pre-gelatinized maize supplemented with varying amounts of soy and carrot flour was evaluated. The blends (Malted pre-gelatinized maize flour : Soy flour : Carrot flour) in grams were: A (80: 20: 0), B (73.125: 23.125: 3.75), C (66.250: 26.250: 7.50), D (65.625: 23.125:11.25), E (65: 20:15), F (63.125: 33.125: 3.75), G (63.125:25.625: 11.25), H (60: 25: 15) and I (100:0:0). There were significant (P ≤ 0.5) differences in the proximate composition of the blends. The moisture content ranged between 3.55 - 8.10%. The protein content of the samples increased (P ≤ 0.5) with the increase in soy substitution and varied from 11.61% for the control (sample I) to 21.53% for sample F. The fat, ash and crude fibre content of the blends varied from 1.68 - 10.86, 1.45 - 2.8 and 0.20 - 4.40% respectively. The control had significantly (P ≤ 0.5) the highest carbohydrate content of 75.61%, while it varied between 55.30 and 71.60 % for others. The energy values varied from 360.43 - 405.00 Kcal/g. The sensory scores were based on a 9-point hedonic scale, with 1 and 9 expressed as dislike extremely and like extremely. The assessors’ likeness for the sensory attributes (colour, texture, taste, aroma and general acceptability) was below neither like nor dislike. This study revealed that substitution with soybeans and carrot flours increased the nutrient composition of the malted pre-gelatinized maize, soybean and carrot flour blends. Particularly the soy flour as sample F with the highest soy flour substitution (33. 123g) had significantly the highest protein (21.53%), fat (10.86%) and energy (405 Kcal/g) values. This would be recommended for good quality porridge. Although, the sensory analysis revealed the need for further investigation on processing methods especially the malting process as to enhance the overall acceptability of the product.

Gluten-free and vegan bakery items have been gaining popularity. Their demand has increased over the past few years, with India being one of the largest gluten-free food consumers. The gluten-free pieces of bread available in the market are crumbly in nature and have a dry mouthfeel, reducing its overall acceptability among consumers. Therefore, the present study was undertaken to develop gluten-free and vegan bread and enrich it with a functional component such as flaxseeds and assess its overall acceptability and nutritional value compared to gluten-free bread available in the market. Once the product was standardized for its serving size and yield, various sensory evaluation trials were conducted using 9 points hedonic scale on bread attributes with the help of semi-trained(n=30)and trained panellists(n=3). Proximate analysis of macronutrients was conducted along with the microbial analysis. The proximate analysis showed that the experimental product had a higher protein content(18.26g)and a lower fat content (5.58g) as compared to the market-bought control sample of gluten-free bread (Total protein content was 3.44g and total fat content was 9.20g). The experimental bread microbial analysis indicated that the total plate count, yeast and mold count, and coli form count were in the acceptable range. Salmonella and E.coli were absent in the sample Statistical analysis using paired t-test was performed found a significant difference between the experimental and control group among the following characteristics: taste/flavour, texture/mouth feel, and overall acceptability (p≤0.05). A shelf-life study of the bread was conducted, and it was seen that the bread remained sensorial acceptable for three days at a refrigerated temperature and four days at room temperature. The bread had a higher nutritional profile than the control sample and received higher overall acceptability.

Out of the thirteen probiotic strains procured from different sources or isolated from thecommercially available sachets, seven isolates showed growth in the ready to serve (RTS)mango beverage. Among the seven strains, only three strains, i.e., Lactobacillus helveticusMTCC 5463, L. rhamnosus MTCC 5946 and Saccharomyces boulardii showed significant growthin the mango beverage. These three strains were further evaluated for population build-up,physico-chemical and sensory evaluation parameters in the fermented mango beverage. Basedon the results of sensory scores, minimum threshold population required for classification asprobioticated beverage and physico-chemical characteristics, L. helveticus was used forprobiotication of the RTS mango beverage. Mango beverage fermented with L. helveticus MTCC5463 showed an average score of 7.34 on a hedonic scale of 9 for overall acceptability, had anacidity of 0.29%, sugar concentration of 7.6% and pH of 4.4. Probioticated mango beveragealso had about 20 and 13% higher phenolics and flavonoids, respectively, compared touninoculated RTS mango beverage. This study has shown that the RTS mango beverageinoculated with L. helveticus MTCC 5463 has potential for developing probioticated mangobeverage.

Purpose The purpose of this paper is to assess the bioactive ingredients of whole flours of oat, maize and soyabean, utilise them for developing functional cookies and evaluate their physical and nutritional quality parameters. Design/methodology/approach Cookies were prepared from blends of whole flours of wheat, oats, maize and full fat soyabean. Whole wheat and oat flours were blend in different proportions (100:0, 80:20, 60:40, 40:60 and 20:80 and 0:100, wheat:oat, w/w) and supplemented with quality protein maize (QPM) and full fat soyabean flours, at 10 per cent (w/w) each, of the total blend. Cookies were studied for their physical attributes, proximate and nutritional compositions. A significant (p=0.05) increase in spread ratio, crude protein, crude fat and crude fibre contents of the cookies was observed with increase in the proportion of oat flour in the blend. Findings Cookies prepared from blend containing QPM and soyabean flours had higher antioxidant activity than control whole wheat cookies. An increase in extractable β-glucan content and in-vitro protein digestibility was also observed with the increase in the proportion of oat flour. The highest overall acceptability was observed for cookies prepared from blends having a wheat–oat proportion of 60:40. These cookies also had a 17.5 per cent higher genistein content as compared to their raw flour blend. Higher genistein levels were observed in the composite cookies. Originality/value The cookies prepared from composite whole flours rich in isoflavones and β-glucan reflect their potential as a new functional food for the prevention and management of diseases such as cancers, diabetes and cardiovascular disorders.

Abstract Beef genotypes and diets can improve the eating quality and consistency of beef. A 2-yr study was conducted to evaluate the effects of beef genotypes and diet on consumer acceptability of beef. Steaks were from Red Angus (RA) and RA x Akaushi (AK) crossbreed, fed one of two finishing systems: grazing (GRASS) and feedlot (GRAIN). Consumers (n = 105 in each year) evaluated cooked steaks for flavor, tenderness, juiciness, and overall acceptability using a 9-point hedonic scale. Demographical information was collected and used as covariates in the statistical model. There was no difference in sensory attributes (P &gt; 0.05) between the genotypes, except that steaks from AK tended to be juicier than RA (P = 0.06). Sensory attributes were scored better in GRAIN than GRASS beef (P &lt; 0.01) for all variables. There was a genotype by system interaction for flavor (P = 0.02), where beef from RA had a lower flavor rating in GRASS than in GRAIN, and no difference was observed for AK. Demographic effects showed that gender and beef consumption location had significant effects on flavor. Flavor scores were higher for females than males (6.1 vs 5.7, P = 0.02), and higher from consumers who eat beef in restaurants than consumers who do not eat beef in restaurants (6.6 vs 5.3, P &lt; 0.01). Juiciness scores were impacted by the frequency of beef consumption. Panelists who eat beef once every 2–3 weeks rated the steaks juicier than those who eat beef once every 2–3 months (6.5 vs 4.3, P = 0.04), and consumers who eat grass-fed beef twice a year rated the steaks worse than those who eat it less than once a year (P = 0.02). Our results suggest that the beef finishing system had a marked impact on consumer acceptability, and AK might produce meat juicier than RA. Some demographic factors may influence consumer perceptions of beef.

The goal of this research is to evaluate the influence of the polyphenols extract of Polygonum multiflorum Thunb. root on the lipid oxidation, chemical properties and sensory characteristics of ground beef during frozen storage. Beef was ground in aqueous solutions of polyphenols extract at different concentrations: 830, 415, 277, 208 and 166 mg GAE/L, polyphenols solution/sample ratio is 1/20 (v/w). Then, the ground beef was stored for up to 100 days at -20±2oC. The best oxidation inhibitor for ground beef was at the highest polyphenols concentration of 830 mg GAE/L. All quality parameters (pH, PoV, MDA, color parameter and sensory evaluation) of the treated sample and of the control sample display significant differences (p<0.05) during storage period. For this reason, it was concluded that the polyphenols extract of Polygonum multiflorum Thunb. root could be used as an alternative source of natural antioxidant in beef processing.
