Background: Chocolate is a popular product that millions enjoy every day due to its unique, rich and sweet taste. Jackfruit seeds rich in nutrients, produce a chocolaty aroma and could be potentially cheap abundant substitute for making chocolate. Hence, the present study was carried out to formulate nutritionally superior chocolates using jackfruit seed. Methods: Jackfruit seed flour was used in varying proportions ranging from 30 to 70 per cent along with 10 to 50 per cent cocoa butter and 20 per cent other ingredients. Other ingredients used were cane sugar, cocoa powder and milk powder. The best treatment was selected through sensory evaluation using a score card with a 9 point hedonic scale. Result: Based on organoleptic evaluation, chocolate prepared with 30 per cent roasted jackfruit seed flour and 50 per cent cocoa butter had a maximum mean score of 8.31 for overall acceptability. The selected roasted jackfruit seed flour based chocolate was subjected to physico-chemical analysis and observed to have moisture (7.62%), carbohydrate (63.03g 100g-1), protein (3.78g 100g-1), fat (1g 100g-1) and fibre (3.13g 100g-1).

The aim of this investigation was to incorporate mustard flour into bread in order to improve its quality. For this purpose, wheat flour 650 type for bread making was replaced with mustard seed flour at the level of 5, 7 and 10%. Bread quality through physico-chemical and sensory characteristics was analyzed and compared to those of bread without mustard flour. The protein content of mustard flour bread increased with 5.03% as a result of mustard flour incorporation, coupled with an increase in ash content. Sensory evaluation results revealed that the sample containing 7% mustard flour scored highest in most of the attributes including overall acceptability. The study reveals that incorporation of 7% mustard flour gave desirable results in terms of phisyco-chemical and sensory caracteristics of mustard flour fortified bread.

The aim of this study was to evaluate the effect of different origin (Venezuela, Ghana, Peru) dark chocolates on emotions induced for consumers, and to analyse the relationships among overall acceptability (OA), emotions, and physicochemical attributes of the chocolate (fatty acids (FAs) and volatile compounds (VC)). Chocolate-elicited emotions were measured with FaceReader 8 software, scaling 10 emotion patterns (neutral, happy, sad, angry, surprised, scared, disgusted, contempt, valence, arousal). The OA was carried out by using a 10-point hedonic scale, ranging from 1 (extremely dislike) to 10 (extremely like). The obtained results showed that, among all chocolate-elicited emotions, the intensity of “happy” was the highest. In most cases, the influence of the different origin chocolate on the emotions induced for consumers was significant (except on emotions “neutral”, “scared”, and “disgusted”). Significant differences between the tested chocolates OA were not found. The origin of chocolate had a significant effect on most of the identified VC and the content of the main FAs (methyl palmitate, methyl stearate, cis,trans-9- oleic acid methyl ester, and methyl linoleate). Significant correlations between chocolate-elicited emotions and separate FAs and VC were found. Finally, this study showed that the origin of dark chocolate significantly influenced most of chocolate-elicited emotions and physicochemical attributes of chocolate, while separate FAs or VC can be used as chocolate quality indicators related to the chocolate OA, as well as chocolate-elicited emotions.

Sugar Replacers

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.

Yoghurt is a popular fermented milk product across the globe. As consumers become more health conscious, there has been rising interest in probiotic yoghurts, fermented with bacteria that can promote human health, as well as yoghurts containing fruit pieces, juice or pulp, which increase the levels of phytochemicals, dietary fibre and some vitamins in the product. Generally, the fruit products are added only up to about 20%. Here we investigated the physicochemical, sensory and microbial properties of analogous fermented products containing milk, but consisting mainly of papaya fruit pulp. Formulations were made at different ratios ranging from 50-100% papaya pulp. Yoghurt (with 0% papaya) was made to serve as the control. Conditions for pasteurization prior to fermentation were optimized for the control of yeasts and molds. The products were fermented with a probiotic culture consisting of Streptococcus thermophilus + Lactobacillus acidophilus + Bifidobacterium spp. Sensory analysis on a 9-point hedonic scale revealed an increase in acceptability of the various attributes with increase in pulp. Formulations containing 80% to 100% papaya fruit were found to be most liked and of comparable quality to the control, having scores of ≥ 7 (ranging from moderately liked to liked very much)) in colour, taste, texture and overall acceptability. Compared to the control, these formulations were found to contain more ascorbic acid, riboflavin, niacin, folic acid, dietary fiber and carbohydrates. The control was however higher in thiamine, protein and fat levels. The products were stable under refrigerated storage (4 ⁰C) for 3 weeks. In conclusion, we found that papaya pulp fermented with a probiotic starter culture, and containing up to 20% milk had good sensory acceptability. The health benefits of such products are worthy of further investigations.

<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>

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.

Ketchup is making of various pulps, but the best type made from tomatoes. Roselle having adequate amounts of macro and micro elements, and it is rich in source of anthocyanine. The ketchup made from pulped of waste of soaked karkede, and homogenized with starch, salt, sugar, ginger (Zingiber officinale), kusbara (Coriandrum sativum) and gum Arabic. Then processed and filled in glass bottles and stored at two different temperatures, ambient and refrigeration. The total solids, total soluble solids, pH, ash, total titratable acidity and vitamin C of ketchup were determined. As well as, total sugars, reducing sugars, colour density, and sodium chloride percentage were evaluated. The sensory quality of developed product was determined immediately and after processing, which included colour, taste, odour, consistency and overall acceptability. The suitability during storage included microbial growth, physico-chemical properties and sensory quality. The karkede ketchup was found free of contaminants throughout storage period at both storage temperatures. Physico-chemical properties were found to be significantly differences at p?0.05 level during storage. There were no differences between karkade ketchup and market tomato ketchup concerning odour, taste, odour, consistency and overall acceptability. These results are encouraging for use of roselle cycle as a raw material to make acceptable karkade ketchup.

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.
