The aim of this paper is to determine the sensory quality of food in restaurants by professional food evaluators and to research the impact of education, age and number of employees on the quality of food.

In the first phase five trained food tasters evaluated the sensory quality of food. In the second phase, the analysis of the structure of employees was done by establishing their level of education, age and number of employees. In the third phase the regression and correlation analysis was done with the aim to establish the impact of the level of education, age and number of employees on the sensory quality of food.

The sensory evaluation has shown that the evaluated food is of moderate quality. Correlation matrix has shown that the education level of employees has a high impact on the sensory quality of food. There is a correlation between the number of employees, their age and their education.

Obtained results are the indicators of the quality of food in restaurants in the region and they can serve for the improvement of quality. They have shown that education and staff training can contribute to a better quality of food. Established methodology can also contribute to the practical evaluation of quality.

This paper is reflected on the specific application of methodology of the sensory analysis of food in restaurants. The paper pointed to the impact of employees on the sensory quality of food by statistical methods. Statistical results which point to the great impact of the level of education of employees on the sensory quality of food in restaurants are particularly valuable.

Cassava is a starchy crop with several industrial applications, but it deteriorates very fast after harvest. Refrigeration has been used to extend the storage life of the root and the starch isolated from the stored roots characterized. Hence, the purpose of this research is to investigate the chemical, functional, pasting and sensory properties of custard prepared from starch isolated from refrigerated cassava root.

Freshly harvest cassava root were cleaned and stored in a refrigerator operating at 4 °C for a period of one, two and three weeks. Starch was extracted from the fresh and stored roots using established method and custard prepared from each of the starch sample. The custard sample was analysed for amylose content, functional, pasting and sensory properties.

Amylose content in the pastes varied significantly from 18.45 to 25.45%. Refrigeration showed a significant impact on the swelling power of the custard, which could be linked to variation in amylose content. Colour and textural properties of the custard were similar across the samples suggesting a minimal impact of refrigeration on the isolated starch. Refrigerated cassava roots can produce acceptable custard with minimal changes in sensory properties if the storage period is closely monitored.

In a previous study, the authors have shown that starch and cooked paste may be made from stored cassava roots without substantial changes in the quality of these products. This study further confirms the possibility of using starch from the stored roots in food applications such as in custard formulation. No report has documented the properties of custard from starch obtained from refrigerated cassava root.

Although milk is considered a vital source of nutrition for the livelihood, as the beginning of civilization, its antioxidant potential is required to be improved. This paper aims to increase antioxidant activities in milk and soy milk (Glycine max L.) has been found as a good compatible source. Hence, the present work was planned to investigate the impact of blending of different proportions of soy milk with standardized milk (i.e. 50 per cent soy milk with 50 per cent standardized milk, 60 per cent soy milk with 40 per cent standardized milk, 70 per cent soy milk with 30 per cent standardized milk and 100 per cent standardized milk as control sample) on antioxidant properties and sensory attributes of the blends.

Antioxidant properties of the blends were determined in terms of 2,2-diphenyl-1-picrylhydrazyl, ferric reducing antioxidant power and total phenol content. Sensory evaluation was carried out using a nine-point hedonic scale based on four selected quality attributes (i.e. smell, taste, color and appearance and mouthfeel) and ranked for their quality traits by fuzzy modeling.

A blend containing 70 per cent soy milk with 30 per cent standardized milk showed the highest antioxidant activities as compared to control milk sample (p < 0.05). Blend of 50 per cent soy milk with 50 per cent standardized milk was found most acceptable on the basis of sensory analysis and its antioxidant activities were also appreciable as compared to control milk sample (p < 0.05). Smell, taste, color and appearance and mouthfeel influenced the acceptability of formulated milk samples in decreasing order of significance (p < 0.05).

The present attempt has been made to formulate liquid milk by mixing standardized milk and soy milk, in which enhancement in the antioxidant activities of standardized milk and masking of off-flavor of soy milk is done. It is not done before and it may improve the nutritional and commercial value of the milk. Further, fuzzy modeling used for choosing appropriate blend in terms of sensory scores is also found as a novel approach.

The effects of incorporation of Locusta migratoria (LM) powder at different levels (0, 1, 2, 3, 4 and 5%) on nutritional, qualitative and sensory properties of baked breads were investigated.

Chemical composition, mineral elements and functional properties of wheat flour, LM powder and their binary mixture systems were determined. The breads were assayed for proximate composition, minerals, amino acids profile, physical characteristics and sensorial properties.

LM powder have relatively high levels of protein (51.97% db), fat (23.15% db) and fibers (13.76% db). LM powder presented significantly (p ≤ 0.05) greater water absorption capacity (WAC), oil absorption capacity(OAC), emulsion activity (EA) and foam capacity (FC) as compared to wheat flour. Blending wheat flour with various levels of LM powder significantly (p ≤ 0.05) improved the functional properties of binary mixture systems. Protein, fat, fiber and ash contents of bread samples significantly increased with the addition of LM powder. No significant differences (p ≤ 0.05) were recorded in specific volume between control breads and those breads containing LM powder up to 2%. Breads fortified with LM powder contained higher values of essential amino acids than the limits of FAO/WHO pattern, with exception of lysine. Sensory evaluation results showed that bread samples with the addition of LM powder at levels 1–4% had high overall acceptability.

Limitations of our study are the lack of approved and professional programs about management, collection, harvesting, processing, marketing and consumption of edible insects; therefore, these results should be generalized implications for industry. This present study, therefore, provides useful data to support public health nutrition aimed at improving the nutritional health of populations through the promotion of bakery products enriched with LM powder.

The main findings of this study indicated that the addition of 1–4% of LM powder into wheat flour enhanced sensory and nutritional properties of produced breads.

It is concluded that the addition of LM powder improves the nutritional and sensorial properties of the produced bread when the wheat flour is substituted with 1–4% of LM powder.

The purpose of this paper is to develop poundmix for reconstitution as pounded yam, from yam, cocoyam, breadfruit and plantain and to evaluate their physico‐chemical and sensory properties.

Instant flour of the components was prepared separately and 30‐50 per cent composite blends of poundmix were formulated. The physico‐chemical, and sensory properties of the poundmix were determined and the results were subjected to appropriate statistical analysis.

The swelling capacities of the poundmix are 3.14±0.03, 3.13±0.04, 3.81±0.01 per cent for 30, 40 and 50 per cent composite levels, respectively, as against 2.27±0.04 per cent for yam flour. Whole yam flour compared well with the composites in terms of peak temperatures with the 40 per cent composite flour having the highest pasting temperature 93°C and 50 per cent composite with the lowest (72°C). However, the higher the composite level the lower the peak viscosity as 390, 260, 210, and 190 BU were recorded for 0, 30, 40 and 50 per cent composites, respectively (F=3.18, p<0.05).

These findings showed that supplementing poundo yam at 40 per cent composite level should be practiced as it gives the best physico‐chemical properties and sensory score.

The purpose of this paper is to investigate the influence of different dietary fibers on color, nutritional, physico-chemical, sensory and textural properties of fresh sausage.

This study was undertaken to determine the effects of partial beef meat substitution (15, 10.5 and 6 percent) at different combinations: barley beta-glucan concentrate (BBC at 1 percent) alone, carrot fiber (ID809 at 1 percent) alone and a mixture of both fibers (BBC and ID809 at 0.5 percent of each), on the quality of fresh sausage.

Results revealed that the supplementation of dietary fibers generally decreased protein contents and increased moisture. Color parameters were significantly affected by the addition of dietary fibers. Meat substitution with dietary fibers tended toward red coloration, which enhanced sensory properties of fresh sausages, especially general acceptability. Fresh sausages formulated with a mixture of dietary fibers recorded good firmness. Indeed, it increased extrusion force values and provided a greater hardness at sensory level. This manuscript reports that beef sausage formulated with a mixture of BBC and ID809 and reduced beef meat rate improved acceptability to consumer.

The paper approaches a new subject that may be relevant to functional food. There are few research works to evaluate consumer preferences of new product developments and to achieve healthier and more economic fresh sausages formulated with a mixture of two fibers after reducing beef meat content.

The purpose of this paper is to substitute wheat flour by passion fruit peel flour in Brazilian honey bread (pão de mel), with evaluation of the breads’ sensory features, chemical composition and physical properties.

Honey breads with wheat flour (standard) and with replacement of this ingredient by 10 to 50 per cent passion fruit peel flour were produced. Two sensory tests were applied, to identify how different formulations with passion fruit peel flour were when compared to the standard formulation, and also the acceptability of the products. The selected honey breads, through sensory results, were evaluated regarding to chemical composition and physical properties.

Formulations with 10 and 20 per cent substitution were the least different to formulations with only wheat flour, and were as acceptable as the wheat flour sample. Physical and chemical characteristics of breads with 10 and 20 per cent passion fruit peel flour were similar; however, honey bread with 20 per cent passion fruit peel flour had higher fibre content, ash quantity and hardness value; a lower specific volume; and a different colour from the wheat flour sample.

This study offers an opportunity to food industries through utilization of an agro-industrial by-product on the formulation of a Brazilian traditional product.

This study presents the feasibility of using an agro-industrial by-product to Brazilian honey bread, enhancing the nutritive value of this product and reducing the impact of passion fruit peel flour on the environment.

This paper aims to develop a good quality pork sandwich spread incorporated with different levels of antioxidant mixture [butylated hydroxyanisole (BHA) + butylated hydroxytoluene (BHT); 1:1] and to assess sensory, physico-chemical and microbiological properties of frozen product during storage.

Three levels of antioxidant mixture (BHA + BHT; 1:1) i.e. 100, 200 and 400 ppm were tried, and the product was compared for physico-chemical, microbiological and sensory properties along with the control during frozen storage (−18 ± 1°C).

pH and water activity decreased significantly (p < 0.05), whereas water holding capacity, 2-thiobarbituric acid reacting substances value, total plate count and psychrotrophic count increased significantly (p < 0.05) during storage period. No coliform, yeast and molds were detected throughout the study period. There was non-significant (p < 0.05) effect of antioxidant treatment on the scores of colour, texture, juiciness, adhesion ability and spreadability, but scores for flavour and overall acceptability significantly (p < 0.05) increased.

Pork sandwich spread is envisaged to help in providing nutrition to a large section of needy population and will add a new dimension to the convenience foods.

Antioxidant mixture (BHA + BHT, 1:1) treatment improved the sensory and microbiological properties of pork sandwich spread at frozen storage (−18 ± 1°C). At the end of storage period (60 days), the pork sandwich spread was found safe for human consumption. Hence, BHA and BHT antioxidant mixture could be used to improve quality attributes of meat products during storage.

This study aims to evaluate the effectiveness of substituting different concentrations of sesame, soy butter, dried moringa leaves and coconut powder on the physicochemical and sensory properties especially calcium and protein content of salted and sweet cookies.

Cookies were prepared by fortifying refined flour with sesame (T1 and T3) and soy butter (T2 and T4) and further fortified with dried moringa leaves (salted) and coconut (sweet). Linear programing was used to formulate percentage of major ingredients to yield maximum calcium and protein. Cookies were evaluated for physical, textural, colour, nutritional, functional and organoleptic properties and compared with refined flour cookies, C1 (salted) and C2 (sweet).

It was observed that fortification significantly decreased the hardness of the test cookies when compared with control. C2 cookies were observed to be the hardest (42.3 N), whereas T2 cookies were the softest (23.7 N). Nutritional and functional components of fortified (T) cookies were significantly (p = 0.01) higher than control (C) cookies, and within T cookies, salted cookies were more nutritious than sweet cookies. Cookies fortified with sesame and dried moringa leaves (T1) contained the highest protein (19 g), calcium (312 mg) and flavonoids (2.0 QE mg/100g) content. Scores on sensory acceptability revealed that T cookies were highly acceptable when compared to cookies for all sensory attributes tested.

Incorporation of protein and mineral rich natural ingredients like sesame, soy butter, dried moringa leaves and coconut powder has improved the nutritional, functional and sensory properties especially calcium and protein content of salted and sweet cookies. There is tremendous scope for utilisation, commercialization of such plant-based nutrient dense ingredients in variety of food snacks, and this will ensure better nutritional security.

Fortification of biscuits with sesame, soy butter, dried moringa leaves and coconut powder resulted in to a superior quality of biscuits in terms of its protein, minerals specially calcium, flavonoid content and organoleptic acceptability. These protein and calcium rich biscuits may help in solving many nutritional deficiencies and can add variety to the bakery industry.

The purpose of this paper is to develop chicken cutlets enrobed with bread crumbs vis-à-vis dried carrot pomace and to assess its effect on physico-chemical properties, sensory attributes and texture profile analysis.

Three experimental groups were made: control group chicken cutlets (C), chicken cutlets enrobed with bread crumbs group (T_b) and chicken cutlets enrobed with dried carrot pomace group (T_c). All the procedures used in the study for estimation of various physico-chemical properties, sensory evaluation and texture profile analysis were standard protocols.

There was a significant (p < 0.05) increase in water holding capacity, crude fibre content and ash content of enrobed chicken cutlets, whereas moisture, fat content and shrinkage of product were significantly (p < 0.05) decreased. The results for sensory evaluation and texture profile analysis of enrobed chicken cutlets were better than control group. Overall acceptability score of chicken cutlets enrobed with dried carrot pomace was revealed to be highest (7.5 ± 0.29) and that of control group was found to be lowest (6.4 ± 0.22). Hardness (N/cm²) value found for control group chicken cutlets, chicken cutlets enrobed with bread crumbs group and chicken cutlets enrobed with dried carrot pomace group were 2.2 ± 0.17, 3.1 ± 0.29 and 4.3 ± 0.27, respectively.

Future research may benefit to assess the effect of enrobing with bread crumbs and dried carrot pomace on mineral and vitamin content and lipid profile of meat products.

Enrobing of chicken cutlets with bread crumbs and dried carrot pomace improved the sensory attributes along with texture profile analysis. Hence, enrobing with bread crumbs and dried carrot pomace could be used as processing technology to improve sensory appeal, especially crispiness of meat products.
