This paper aims to prioritize National Board of Accreditation (NBA) quality parameters in engineering education as per student’s needs using quality function deployment (QFD). Design/methodology/approach This study is conducted among students of an institute of National importance in three stages. Stage 1 involves conducting interview with 23 students to find the student’s requirement from an institute. Further Stage 2 involves importance rating collection through questionnaire survey method. In this stage, 228 students have given a rating of each student’s requirement. Finally, Stage 3 involves establishing correlation between student’s requirement and NBA quality parameters that has been done by 20 academic experts and finally making a QFD matrix for ranking of each NBA quality parameter. Findings The result of the study first indicates that among all students’ requirements, job-oriented requirement is the most important need, and ergonomics-based requirement is the least important need of students. Further, to fulfill their needs, an institute has to focus on each NBA quality parameter. But among all NBA quality parameters, student’s performance is highly desirable quality parameter. Practical implications This study will help top management of engineering institutions in making better policies and strategies for preparing their quality framework. These strategies will indirectly fulfill the customer needs that help in attracting more number of students toward those institutes. Originality/value In India, NBA is one of the leading bodies that monitor the quality of education. On the other hand, the institution has to satisfy the need of customer of education sector; therefore, prioritization of NBA quality parameter as per student’s need is one of the important needs that will help engineering institution to focus on a certain parameter to get a good quality certificate and also attract a number of meritorious students.

There is an upward trend towards reducing or suppressing additives in foods, as well as reducing the use of E-numbers in labels providing clean label foods. Therefore, the development of confectionary products based exclusively on natural ingredients with antioxidant properties may offer valuable solutions to the confectionery industry. Fruit juices and purées may provide functional and organoleptic properties in jelly candies in a natural way. The consumption of pomegranate fruit and derivative products has increased due to their association with health benefits. The aim of this study was to determine consumer insights about pomegranate-based jellies, cultivar “Mollar de Elche”, as affected by formulation (100% pomegranate juice or 50%–50% pomegranate juice–apple purée) and type of sweetener (sugar or honey), and to link affective and descriptive data from sensory studies. The most valued quality parameter of pomegranate products, red color (measured by the green–red coordinate, a*), was not negatively affected by jelly preparation. It was determined that the main liking drivers for pomegranate jellies were intense red color and high brightness. The results might be used by pomegranate processing companies to improve their manufacturing protocols and to develop successful products meeting consumer demands and needs. The formulation containing 20% gelatin, pure “Mollar de Elche” pomegranate juice, 1% citric acid, and sucrose as sweetener provided the best quality of jellies in terms of color, texture, antioxidant capacity, and sensory attributes.

Rusk and ring-shaped bakery products relate to the group of long-stored ones. For today it is urgent to use ingredients that give products functional properties in food technologies. The important source of food fibers, full-value protein, unsaturated fatty acids, mineral substances and vitamins are grain and oil-bearing crops. Buckwheat and flax seeds are separated among them due to the valuable chemical composition and positive effect on the human organism. The aim of the work was to establish the influence of buckwheat flour and flax seeds on the technological process course and quality of long-stored bakery products. Buckwheat flour of green and dark buckwheat of TM “Organic-Eco-Product” (Ukraine) is used in the rusk technology. For producing ring-shaped products (ring-shaped crackers), gold flax seeds were used. Research results testify that good quality parameters of bread for producing rusks from it, were achieved at dosing green buckwheat seeds as 20 % and dark ones as 15 % instead of the flour mass. It has been established, that rusks with adding green buckwheat flour have quality parameters, corresponding to requirements of normative documents. It has been proven, that it is not expedient to use dark buckwheat flour in the rusk technology, because ready products have the increased water share and soaking index. It is connected with the influence of the operation of hydrothermal processing of grains that dark buckwheat flour is produced of, its high water-absorbing and water-retaining capacities. For the technology of ring-shaped crackers, enriched with flax seeds, it is recommended to dose flax seeds as 15 % of the flour mass. At such dosage bakery products got the highest number of points by the complex quality parameter and corresponded to requirements of normative documents.

Forage harvest belongs to the principal works in contemporary agriculture. Increasingly popular technology is the making round bales. The basic advantage of round balers is application versatility. Harvest method is useful for making hay, straw and haylage, Quality of the bale is dependent on the level of work equipment and operator. This paper is focused on comparing the round baler with variable bale chamber. Round baler Vicon RV 1601 OC14 was compared with round baller Welger RP 435 Master. Both models were equipped with variable chamber. The variable chamber was formed by the endless belts. The evaluation was conducted from quality of work perspective and efficiency. The most important quality parameter was the density of bales. Quality parameters of bales were determined by measuring and weighing. Straw bales and haylage bales were used for studies. Qualitative indicators were converted into dry matter content. Microwave drying according to Swedish University of Agricultural Sciences was used to determine the dry matter. Baler Welger reached better qualitative parameters of work. It was also demonstrated by statistical evaluation using Tukey test. It has clearly demonstrated that round baller Welger achieves significantly greater pressing than round baller Vicon. Greater difference was measured at baling straw. Difference was below the threshold of statistical significance during haylage baling. This difference shows favour of the round baller Welger. On the other hand baler Vicon requires lower input power.

Modern technologies of food products provide creation of healthy, tasty and safe products, characterized by high organoleptic properties, balance by main food factors and structural-mechanical parameters of a product. The main technological process in the technology of fish marinades and a jelly pouring is the hot smoking. Technological parameters of the hot smoking have been scientifically grounded on the base of the statistical processing of data of sensory studies. Organoleptic assessment of semi-products after the thermal processing was carried out by 5-point system corresponding to the elaborated scale. The quantitative assessment of organoleptic parameters of the quality of experimental samples was determined by the totality of all assessment points, taking into account chosen weight coefficients depending on the importance degree of a given parameter at forming consumer qualities of a product. The generalizing quality parameter was calculated as a sum of assessments of organoleptic parameters – taste, consistence and appearance. Individual assessments of separated quality parameters of products (in points) were put in degustation lists and statistically processed by the averaging method. The smoking process realization, according to scientifically grounded parameters allows to produce the new type of tasty, healthy and presentable culinary products of a perspective object of Ukrainian aquaculture – silver carp of a prolonged storage term.
