Soy corn yoghurt is a vegan friendly product prepared by using soymilk as the major ingredient. The aim of this study was to assess the effect of corn milk addition (0, 10, 20, 25 & 30%) on the quality of soy yoghurt. The samples were subjected to sensory evaluation for consumer acceptability and data were subjected to statistical analysis. From sensory evaluation and statistical analysis 10% corn milk inclusion was selected as the best product (p<0.05). The yoghurt thus prepared using 10% corn milk had total solids 22.04%, moisture content 78.62%, protein 4.84%, fat 3.29%, carbohydrate 12.57%, ash 0.81%, acidity 0.68% and pH 4.58. Both control and 10% corn milk incorporated yoghurts were stored under refrigeration 6±1° C and analyzed at 2 days interval till 10 days. Yoghurts with corn milk and control were organoleptically acceptable up to 10 and 6 days respectively. Acidity and syneresis increased but pH decreased with storage time in both samples.

The present study was concerned with the preparation of potato flour with various treatments and to formulate the chapatti and biscuit incorporating potato flours were prepared by treating the raw potato slices as blanched, blanched plus potassium meta-bisulphite (KMS) treatment and one as control. Various substitution levels from 15 % to 30 % of potato flour was used in the formulations of chapatti and biscuit in conjunction with wheat flour. Chapatti and biscuit prepared with either blanched or blanched plus KMS treated sample of potato flour had very good physical and baking quality. And chapatti prepared with 20% potato flour and biscuit containing 25 % had the most suitable baking properties among other proportions. The statistical analysis of sensory evaluation data indicated that the baked products prepared with potato flour from blanched plus KMS-treated samples ranked very well and were more acceptable than those made from blanched sample.

Before And After

Samples of three types of honey: polyfloral (PH), linden (LH) and acacia (AH,) without and with addition of dried cherries (40%) were analyzed before and after three months of storage. The total phenol (TPh), flavonoid (TFd) and anthocyanin (TAn) contents, antioxidant activities and sensory properties of honeys with and without the addition of dry cherries were evaluated. TPh and TFd increased with addition of dried cherries to the honey, while enriched honeys showed high TAn. The LH sample with dried cherries showed the highest anthocyanins content (41.41mgCGE/100g). The antioxidant activity increased with addition of dried cherries in honey in the DPPH? test and reducing power. The PH and enriched PH exibited the best antiradical activity compared to LH and AH. The EC50 DPPH values were: 23.81 for PH and 24.19 mg/mL for PH, while the EC50 DPPH were: 1.16 mg/mL for PH40 and 1.18 mg/mL for PH40s. RP0.5 values were: 57.00 mg/mL for PH40 and 56.00 mg/ml for PH40s, while RP0.5 were: 15.05 mg/mL for PH40 and 15.18 mg/mL for PH40s. The statistical analysis showed that TPh, TFd and TAn, and antioxidant activity of honeys and enriched honeys showed significant correlation. Sensory analysis of honey with dried cherries, before and after storage, indicated very good sensory characteristics.

Moringa oleifera is local plant rich in nutrients, unfortunately its utilization as a foodstuff is limited. In order to maximize the absorbtion of nutrients inside moringa, it should be made as favor food enjoyed by the people such as jelly candy. This research was conducted to evaluate organoleptic properties and nutritional value (energy and â-caroten) of jelly candy formulated with Moringa leaves powder. Using Comlpetely Randomized Design with 6 times repetition in 4 formulas which are 1 controlled formula and 3 modifi ed formulas (F1, F2, and F3), jelly candy then tested to 32untrained panels. Treatment given in this study was by adding 2%, 4%, and 6% moringa leaves powder into jelly candy formula. Data was analyzed descriptively and statistically using Kruskal Wallis and Mann Whitney test to fi nd out the difference pair. Recommended formula was chosen by counting the highest mean score of the sensory evaluationtest. The result of sensory evaluation showed that Moringa Jelly Candy was generally accepted with category “like”. However, jelly candy with lowest level of Moringa leaves powder (F1) was most acceptable in terms of color, odor, texture, and fl avor. Statistical analysis showed that the scores of color, odor, and texture were not signifi cantly different (p > 0.05) and fl avor was (p < 0.005) which means that by adding moringa leaves powder into jelly candy formula only infl uence the fl avor of jelly candy. Recommended jelly candy formula is F1 with nutritional analysis showed that per 100 g of jelly candy contains 205,8 kcal and 0.178 mcg of B -caroten.Keywords: moringa leaves powder, sensory evaluation, Moringa oleifera, jelly candy

Três diferentes formulações de vinagre de folhas de videira foram elaboradas, mantendose a proporção de folhas e água, e variandose a concentração da sacarose. Realizouse análise sensorial das formulações, segundo os atributos aparência geral, cor, odor, sabor geral e acidez, além de análise química de acidez titulável. Vinagres comerciais de vinho branco e vinho tinto foram utilizados como padrões. Concluiu-se que somente a formulação com maior teor de sacarose apresentou porcentagem de ácido acético de acordo com os padrões recomendados para tais produtos. Considerando a avaliação sensorial, duas formulações não diferiram significativamente dos vinagres comerciais. Abstract Three different vinegar formulations from grapevine leaves were elaborated, maintaining the waterleaves rate and varying the saccharose concentration. Sensory evaluation of the formulations was realized by the characteristics: general appearance, color, odor, general taste and acidity, in addition to chemical analysis of titratable acidity. It was employed commercial vinegars of white wine and red wine, as standards. It was concluded that only the formulation with higher saccharose rate showed acetic acid percentage within the recommended level for this products, however, two of the formulations tested did not differ meaningfully from commercial vinegars.

Yam (Dioscorea spp.) is a tuberous plant of high energy and nutritional value, with great importance for the industry and as a food because of its composition. With the purpose of developing bakery products and determining its acceptability, cake, biscuit, pasta, pancake, bread, and pizza were prepared with 0 to 20% of starch in substitution for wheat flour. Yam starch was obtained when arriving at the industry in Caapiranga-AM, the flagship yam processing town in the region. Sensory evaluation was carried out by a target audience of 50 individuals, using a hedonic scale. For the statistical analysis, the Tukey&rsquo;s test was used, and it was found that in the overall analysis, the best treatments were the control (no yam starch) and the one with 5% of yam starch. The production of these byproducts is viable, adding value to yam and delivering a product with better quality to consumers.

Traditional airag (fermented mare’s milk) is a sour, slightly alcoholic drink handmade by Mongolian nomads. As airag is not heated after production, the fermentation continues to proceed and the taste changes rapidly. The objective of this study was to investigate the association of the sensory taste evaluation of airag with some properties—electrical conductivity (EC), pH and concentrations of macro minerals (calcium (Ca), phosphorous (P), sulfur (S), magnesium (Mg), potassium (K), and sodium (Na))—of airag. We held an airag contest in Mogod county, one of the most famous airag production areas, in order to collect samples of airag for the analysis of airag properties and to conduct an airag taste evaluation by Mongolian people. The results of the statistical analysis indicated that the EC-value was related to the evaluation score of airag. Except for EC, no statistically significant relationship between the taste score and the other properties was found in this study. It was concluded that the EC-value would be a simple measurement indicator for evaluating the quality of airag on site.
