The increasing numbers of overweight or chronically obese individuals have led the market to produce sweet snacks and desserts that are low in calories, low in fat or low in sugar. Sugar replacers have low calorific value and lower glycaemic index as compared to sucrose which not only helps in controlling weight but also is safe for diabetics. The study is aimed to develop a sugar free chocolate by using a combination of various zero calorie sweeteners i.e., stevia, isomalt and erythritol through response surface methodology (RSM). The final run optimized by RSM consists of 21.9g cocoa butter, 5.1g erythritol, 0.10g stevia and 14.9g isomalt. Organoleptic evaluation of modified chocolates was evaluated using 9 point hedonic scale for the parameters like, appearance, color, aroma, taste, texture, mouthfeel, aftertaste and overall acceptability. The overall acceptability of sugar free chocolates was found to be 8.9. Further, the fortification of chocolates was done with the help of vitamins and minerals rich fruit powders such as beetroot powder, jamun seed powder and pink pithaya powder (dragon fruit). Vitamins and minerals analysis was performed for sugar free chocolate fortified with beetroot. Shelf-life study of sugar free chocolate fortified with beetroot was carried out.

<p>Studies were carried out to optimize the percentage of ingredients for the development of ready to eat mutton bar. Central composite rotatable design of response surface methodology (RSM) was used for designing the experimental combinations. Matrix for compression was designed by selecting factors like mutton powder, binders and applied pressure. Protein percentage, hardness and over all acceptability (OAA) were taken as responses. OAA and hardness showed highly significant and fitted with quadratic model whereas other response i.e. protein levels found to be significant and fitted with linear model. From the design of experiments 45g/100g of mutton powder with 5g/100g binders having an applied pressure of 142 kg/cm<sup>2</sup> yielded a bar having a protein percentage of 35g/100g with a hardness of 20.9 N with an overall acceptability score of 8.6 ±0.2 on a 9 point hedonic scale. The product gives energy of 393 kcal per 100 g.</p>

Oat (Avena sativa L.) is an underutilized cereal and is considered as a rich source of protein, minerals, lipids, β-glucan and other phytochemicals. It has an immense scope for its application in preparation of various nutraceutical and functional foods. Oat flour was incorporated with wheat flour at different concentrations for preparation of breads and noodles. Breads were prepared by incorporation of oat flour (OF) in wheat flour (WF) at different levels (0, 10, 15, 20 and 25%). Overall acceptability of breads decreased with increase in level of oat flour. However, breads were moderately desirable up to 20% replacement of WF with OF and slightly desirable at 25% level of replacement. Significant decrease in loaf volume of oat incorporated bread (OIB) was observed with increase in level of incorporation of OF in WF. Oat incorporated noodles (OIN) were prepared by substitution of OF in WF at proportion of 0, 10, 20, 30 and 40%. These were moderately desirable only up to 30% replacement of wheat flour with oat flour and slightly desirable thereafter. There was significant (P≤0.05) increase in proteins, crude fibres, ash and fat content but significant decrease in carbohydrate content and calorific value of processed products was recorded with increased incorporation of OF in WF. Results of organoleptic evaluation concluded that bread and noodles were moderately desirable up to 20 and 30% replacement of wheat flour with oat flour, respectively. Therefore, oat can be successfully substituted with wheat flour upto a level of 20% for bread and 30% for noodle preparation thereby, enhancing the nutritional components such as crude protein, fibre, fat and ash content in prepared products.

Breakfast cereal plays an important role in a balanced diet. In Malaysia, tons of highly nutritious banana peels, overripe, oversupplied and rejected bananas end up in food waste, as a result of high production and consumption of banana. Thus, this study aimed to produce flaked breakfast cereal with banana pulp, banana peel and cornmeal through oven -baking. Baking temperature, baking time and volume of banana pulp and peel mixture were optimized by using response surface methodology (RSM) to achieve desired fracturability and yellowness. Through this study, fracturability (R2 = 0.98, P≤0.05) and yellowness (R2 = 0.99, P≤0.05) were found to be significantly related to the processing parameters and formulation of the flakes. The optimum processing parameters and formula obtained from this study were the baking temperature of 129.5°C, baking time of 15 mins and volume of banana pulp and peel mixture of 140 g. Besides, a sensory evaluation was conducted and compared among the optimized flakes and commercial corn flakes. Based on the results, there was a significant difference (P≤0.05) in aroma, appearance and taste but no significant difference (P>0.05) in mouthfeel and overall acceptability between both types of flakes. It was recommended that the shelf-life study of the optimized flakes could be done for future study.

<p>Malnutrition is one of the causes of triple burden on the nation. It is decreasing in South Asian countries but still almost 83 million are suffering<sup>1</sup>. To combat the condition of malnutrition, bio-fortified crops are being developed. One of the crops which were developed is quality protein maize; maize with better biological value and balanced amino acid profile which helped in increasing the absorption of other vitamin A, calcium and carbohydrate 2. In this background, the present study was planned with an objective to develop biscuits with optimum sensory and nutritional attributes which can help in impeding malnutrition. The biscuits were subjected to organoleptic evaluation by the panel of 10 semi-trained judges. A 9- point hedonic scale was used for evaluating sensory attributes of the developed biscuits. There was insignificant difference between overall acceptability score of the developed biscuits but was highest for the biscuits developed from quality protein maize. The quality protein maize containing biscuits had high protein (8.11 g/100 g), ash (1.46 g/100 g), lysine (3.66 g/100 g protein), methionine (1.66 g/100 g protein), tryptophan (0.84 g/100 g protein), linoleic (25.57%), linolenic acid (1.66%) and in vitro protein (81.92%) and starch digestibility (53.18%) acceptability in comparison to wheat biscuits. Thus, incorporation of quality protein maize in the development of bakery products helped in improving the nutrient contents and thus is a good alternative to be used during feeding trial.</p>

Roasting of cocoa beans is a critical stage for development of its desirable flavour, aroma and colour. Prior to roasting, cocoa bean may taste astringent, bitter, acidy, musty, unclean, nutty or even chocolate-like, depends on the bean sources and their preparations. After roasting, the bean possesses a typical intense cocoa flavour. The Maillard or non-enzymatic browning reactions is a very important process for the development of cocoa flavor, which occurs primarily during the roasting process and it has generally been agreed that the main flavor components, pyrazines formation is associated within this reaction involving amino acids and reducing sugars. The effect of cocoa nib roasting conditions on sensory properties and colour of cocoa beans were investigated in this study. Roasting conditions in terms of temperature ranged from 110 to 160OC and time ranged from 15 to 40 min were optimized by using Response Surface Methodology based on the cocoa sensory characteristics including chocolate aroma, acidity, astringency, burnt taste and overall acceptability. The analyses used 9- point hedonic scale with twelve trained panelist. The changes in colour due to the roasting condition were also monitored using chromameter. Result of this study showed that sensory quality of cocoa liquor increased with the increase in roasting time and temperature up to 160OC and up to 40 min, respectively. Based on the Response Surface Methodology, the optimised operating condition for the roaster was at temperature of 127OC and time of 25 min. The proposed roasting conditions were able to produce superior quality cocoa beans that will be very useful for cocoa manufactures.Key words : Cocoa, cocoa liquor, flavour, aroma, colour, sensory characteristic, response surface methodology.

A study on organoleptic evaluation for accessing sensory attributes of lycopene containing tomato purees & its overall acceptance was conducted at Food Science Analysis Laboratory, School of Home Science, B.B.A.U, Lucknow, Uttar Pradesh, India, during July 2020 to May 2021. Different treatments under the investigation were prepared using dried tomato (Lycopersicum esculentum), tomato pulp and water to find out most appropriate treatment having significantly higher sensory attributes and overall acceptability. Five different types of treatments/purees viz. Dried tomato powder without food additives (T1), Mixture of tomato powder and water (ratio 1:10) without heating (T2), Mixture of tomato powder and water (ratio 1:10) heating at 60-70 ᴼC for 5 minutes (T3), Fresh tomato pulp (T4) &  Tomato pulp cooked at 60-70 ᴼC for 35 minutes (T5) were used in the investigation. The effect of these treatments was distinguished as reflected on sensory characters like appearance, aroma, texture & overall acceptance. The highest overall acceptance of 8.20±0.7 on hedonic scale was obtained from tomato pulp cooked at 60-70 ᴼC for 35 minutes (T5) followed by dried tomato powder without food additives (T1) ie. 7.90±1.0. These results appeared highly promising depending on the appearance, aroma & texture.

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.
