This study examined the addition of carrot paste (CP) at levels of 3%, 5%, and 10% as a potential antioxidant in frankfurter-type sausages, denoted as F1, F2, and F3. F0, was a control sample with no addition of CP. All formulated samples were stored for 14 days during which their physicochemical, oxidative stability, and sensory properties were evaluated. Results showed that the pH of frankfurter-type sausages was not affected by the addition of CP, however, higher pH values were observed in CP-enriched samples on the first day of production and subsequent storage days. Cooking loss (CL) in frankfurter-type sausages was in the range of 2.20% to 2.87%, with the CP-enriched samples having a lower CL percentage, particularly F3 samples, compared to the control. Protein and fat content were lower in CP-enriched samples, but ash content increased. CP-enriched frankfurter-type sausages recorded significantly higher polyphenol contents compared to the control. Total polyphenol content in CP-enriched samples F1, F2, and F3 was higher throughout storage compared to the control. Lower peroxide values were also recorded in CP-enriched samples F1 (2.5 meq/kg), F2 (2.4 meq/kg), and F3 (2.2 meq/kg) compared to the control (2.9 meq/kg), demonstrating greater 2,2-Diphenyl-1-picrylhydrazyl (DPPH) antioxidant activity than the control samples. Formulations treated with 10% CP gained significantly higher scores for color, texture, and overall acceptability. Principal component analysis showed that higher inclusion levels of CP in formulation improved the sensory quality and oxidative stability. In conclusion, CP could be used to enhance the oxidative stability of frankfurter-type sausage without negatively influencing the sensory quality.

Breakfast strips were produced from different blends of orange-fleshed sweet potato (Ipomea batatas), plantain (Musa paradisiaca) and soybean (Glycine max) flours with substitution ratios of 100:0:0, 90:10:0, 90:0:10, 80:10:10, 70:15:15, 60:20:20 and 50:25:25 and labelled as samples A, B, C, D, E, F and G, respectively. The blends were evaluated for functional properties, total carotene, vitamins (B2 and B6) and sensory properties of the breakfast strips with a commercial breakfast food (Flakes) as control (sample H) . For the functional properties, the water absorption capacity decreased while the oil absorption increased with an increase in substitution levels of the soybean flour. The bulk density, solubility, swelling power and swelling volume were higher in sample A. The least gelation capacity maintained a constant rate of 4% across the blends. The moisture content of the strips ranged from 7.25-9.40%. The Ash contents were below 3% for all the blends. The protein contents increased with an increase in substitution with soybean flour while sample A - breakfast strips from 100% orange-fleshed sweet potato flour showed the highest value for fats (5.62%). The fibre content ranged from 0.69 to 5.14% and carbohydrate content reduced with an increased substitution with soybean flour (72.25-78.70%). The energy value ranged from 351.90-384.80 Kcal/100 g which was within the limit recommended for breakfast foods. Total carotene content increased with increased substitution with orange-fleshed sweet potato (15.18-33.56 mg/kg) which is significantly higher than the control at 0.75 mg/kg. The result of the sensory evaluation showed that the overall acceptability of the samples produced compared favourably with the control. Sample A and B showed a vitamin B2 of 4.70 and 4.00 mg/kg, respectively. However, the values decreased with increase in the addition of soybean while vitamin B6 increased with increase in soybean.

The study examines consumer sensory preferences of 12 different handmade pastry products in the form of minions, made of rice and flaxseed flour, tapioca starch with natural taste ingredients and with addition of prebiotic (inulin), herbs and other ingredients. The sensory evaluation was performed by professionals (experienced tasters). Preferred minion flavour was tested at group of 324 consumers (hotel guests) of different nationality. ANOVA and t-test were performed to reveal differences in attitudes related to socio-demographic characteristics of the consumers. Also, determination of taste preferences according to consumer nationality was examined as an additional consumer care aspect. The evaluation of equality of the samples? average rates, as well as the groups of minions, is done by parametric or nonparametric model of variance analysis. Principal component analysis (PCA) was applied in order to group the investigated minions regarding their sensory properties, while the sum of ranking differences (SRD) was used to determine the minions with the best sensory properties. Consumers and experienced tasters have almost the same opinion about the sensory quality of minions, which indicates that assessment of the consumer can be considered as a representative opinion in the near future. Such functional food - minions could be widely used as a substitute for the most common commercial sweets rich in sugar and fat.

The aim of this study was to incorporate brown flaxseed into bread in order to improve it quality. For this purpose, different levels of whole ground brown flaxseed (5%, 10%, 15% and 20%) were used to substitute wheat flour 650 type of a very good quality for bread making. The bread samples obtained were analyzed from the physical, colour, crumb cell, textural and sensory characteristics point of view. Samples containing 10% of brown flaxseed were with the highest values for loaf volume, porosity and elasticity. The control sample had lowerest redness and greenness value. The maximum hardness was found for bread with 20% brown flaxseed addition. With the increase level of brown flaxseed addition large cells can be noticed in crumb structure of bread. Samples containing 20% of flaxseed were rated poorest in tase, texture, overall acceptability, appearance. Our results indicated that brown flaxseed addition could be added to a typical bread formulation up to levels of 10% with a good overall acceptability offering promising healthy and nutritious alternative to consumers. Between bread flour characteristics at different brown flaxseed flour substitution levels principal component analysis shown significant correlations (p < 0.05) between bread physical characteristics (loaf volume, porosity, elasticity) and bread  overall acceptability.

The effect of fat content and added yoghurt, honey and pomegranate juice concentration on the overrun, and the physicochemical, rheological and sensory properties of frozen yoghurt samples was investigated, aiming in the production of a novel low-fat and functional dairy fermented frozen dessert. For this purpose, the methodology of mixture experiment was applied to twenty samples, while a control sample (without using honey and pomegranate juice) was also produced. According to the results, the increase in yoghurt concentration resulted in increasing pH, overrun, brightness, elastic modulus (G&acute;) determined at -2 &deg;C and sensory hardness of the samples, while it reduced color parameters a* and b*, creaminess, sweetness and fattiness. Increasing honey concentration reduced lactic acid concentration, G&acute; at -2 &deg;C, hardness, sensory acidity, and to a lesser extent pH, while increased color parameter b*, overrun, sensory color intensity, creaminess, sweetness, and fattiness of the samples. The increase in pomegranate juice concentration resulted in decreasing pH, brightness and b*, as well as increasing a*, color intensity, creaminess and sensory acidity. Finally, fat, by interacting with one or two of the three constituents (yoghurt, honey and pomegranate juice), decreased pH, creaminess and fattiness, while increased lactic acid concentration, b*, color intensity and to a lesser degree the overrun level of the samples. Overall acceptability of the samples indicated that it is possible to use honey and pomegranate juice in the production of low-fat frozen yoghurt with favorable sensory properties.

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.

The whole buckwheat flour (WBF) was used in Turkish flat bread, lavaş, up to 30% level without gluten, and up to 40% level with gluten and sodium stearoyl-2-lactylate (SSL) additions. Some physical, chemical, and sensory properties of lavaş bread samples were determined. While ash, crude fiber, phytic acid (PA), Fe, K, Mg, and P contents of lavaş breads increased with WBF addition, gluten supplementation caused an increase especially in protein and Ca contents. Leavening process decreased PA contents in the breads compared to raw material, but WBF substitution increased PA contents up to 729 mg/100 g. As a result, the utilisation of WBF in lavaş bread improved the nutrients contents of the bread except PA. The dark colour and slight bitter taste of the WBF affected the sensory score of lavaş bread negatively at 40% substitution level, but the overall acceptability values did not change significantly (P &lt; 0.05) compared to control sample.

Amrakhand is a variation of shrikhand where it is mixed with pureed mango popular in western part of southern peninsula of India; consumers in Gujarat prefer its sweet variety while those in Maharashtra prefer the tangy/soury variety. High sugar content in the Amrakhand contributes to the total energy intake; carbohydrate is the most restricted item in the diet of both dietetic and diabetic individuals. Stevia is a natural sweetener with zero calories and its beneficial influence on human health, there is a great possibility of its use in food industry. The main aim of study was to investigate the sensory quality of Amrakhand prepared by using stevia leaf extract powder at different level of concentrations. Six different concentrations of sucrose and stevia used were 30:70(T1), 25:75 (T2), 20:80 (T3), 15:85 (T4), 10:90 (T5) based on quantity of chakka. Control sample (T0) was prepared from 100:0 sucrose and stevia leaf extract powder concentration. Sensory attributes (colour and appearance, flavor, Mouthfeel, Body and texture, taste and overall acceptability) were judged by panel using 9- point hedonic scale the preferred order of samples was as follows : T1>T2>T0>T3>T4>T5. Amrakhand with treatment T1 (30:70) was more acceptable by the panel of judges.

Aims: To investigate the effect of supplementation of kunu-zaki with milk on its nutritional and microbiological qualities and overall acceptability. Place and Duration of Study: Department of Science Laboratory Technology, Faculty of Applied Sciences, Rufus Giwa Polytechnic, Owo, between April, 2019 and July, 2019. Methodology: The two (2) Kunu-zaki blends were produced by traditional fermentation method, thereafter, they were screened for the presence of microorganisms using pour plate method while colonial characteristics and biochemical tests (Sugar utilization, catalase, coagulase, oxidase) were done to confirm the identity of the organisms. The proximate composition (moisture, protein, lipid, ash, fibre and carbohydrate) of the samples were assayed using standard procedures. The sensory properties of the Kunu-zaki were assessed using a trained panel. Data were analyzed statistically using SPSS version 17.0 and the means separated using Duncan Multiple Range Test. Results: Coliforms and Enterobacteriacea were not found in the enriched and control Kunu-zaki samples. However, the highest total heterophilic bacterial count (107x103 cfu/ml) and lactic acid bacterial count (131 x103 cfu/ml) were found in sample B while the least counts were found in the control sample with 92 x103 cfu/ml and 122 x103 cfu/ml total bacterial and lactic acid bacterial counts respectively. Further, the highest fungal count was found in control sample (67 x103 sfu/ml) while the least count were observed on sample B (52 x103 sfu/ml). The control sample had the lowest pH 4.65 while sample C had the highest pH of 5.95. Also, the TTA ranged between 0.57% I sample C and 0.83% in control sample. A total of six (6) bacteria and six (6) fungi were isolated from the freshly prepared kunu-zaki-tigernut milk blends, they were Bacillus subtilis, Bacillus licheniformis, Micrococcus luteus, Lactobacillus acidophilus, Lactobacillus plantarum, Streptococcus species, Geotrichum candidum, Saccharomyces cerevisiae, Aspergillus niger, Rhizopus stolonifer, Fusarium and Penicillium species. The crude protein, moisture content and fat of the enriched Kunu-zaki were significantly (p≤0.05) higher than the control sample. Also, there was a reduction in fibre, ash and carbohydrate content of the enriched Kunu-zaki product compared with the control sample. The enriched Kunu-zaki samples had higher level of potassium, magnesium and phosphorus than the control Kunu-zaki while they had lower calcium and sodium concentrations. Kunu-zaki-tigernut milk blends had comparable rating to the control in appearance and aroma but had a higher rating for taste and overall acceptability. Conclusion: The enrichment of Kunu-zaki with tigernut milk had significant elevating effect on the nutrition and sensory properties of the Kunu-zaki and its overall acceptability.
