Apple juices are already well-known and appreciated products, which under certain conditions can be enriched with vitamins, minerals and other nutrients, contributing to increasing nutritional intake as well as to completing some nutritional deficiencies. Such an approach often constitutes sustainable solutions from an economic and process point of view. Obtaining these new types of apple juices ensures the completion of their already known nutritional benefits with the therapeutic ones brought by the intake of ho...

In this research, we studied wines from eleven wine regions of Romania (Stefanesti, Dragasani, Dealul Mare, Minis, Blaj, Babadag, Focsani, Tarnave, Silagiu, Iasi, Cotnari), but also for two years of different production (2019 and 2021), to observe their chemometric profile according to the geographical origin. The chemical composition was determined for 40 white wines and 34 red wines. The studied chemical parameters were alcohol concentration, wine density, total acidity, free and total sulfur dioxide, non-reduci...

With the development of food production technologies, the consumers attention has turned to products with specific nutritional and health-promoting properties. For this necessity, today's manufacturers have turned their attention to fortified foods, and a raw material that is found in great diversity and that can be used to enrich food is represented by mushrooms. The purpose of this study consists in determining how the addition of different concentrations of crued polysaccharides extracted from mushrooms and add...

This thesis studies the impact of the addition of two types of enzymes: Rohapect PTE-100 and Pectinase to 6 varieties of apple, grown in the Valea Dambovi?ei area in order to improve the quality of apple juice. The 6 apple varieties used are: Sirus, Florina, Red Topaz, Golden, Starkrimson and Rozela. Thanks to the new varieties planted, and the use of modern technology, the production of apples has increased, and the apples are used fresh or processed in the form of natural juice as such or mixed with other fruits...

Sustainable food production is growing along with consumer demands to find healthy products. The management and minimization of food by-products and the recovery of products with low economic value represent both a trend and a current necessity for the food industry. Prunus cerasifera is a species of plum native to Southeast Europe and Western Asia. It is also called Cherry Plum and Myrobolan Plum. It is cultivated mainly as an ornamental plant with several varieties differing in leaf and bud color and secondarily...

Food waste is a growing global concern, with the attention of major global organizations focusing on monitoring and finding solutions to optimize it. According to the latest data published by the National Institute of Public Health on this topic (2019), in Romania, food waste is estimated at 6,000 tons per day 49% from households, 37% from the food industry, 7% from retail, 5 % of public catering and 2% of the agricultural sector. In this context, it was proposed to implement a system based on reducing waste and w...

The concept of sustainable development involves economic development, social development, ecological development, political development, human development, spiritual and cultural development. All these elements pursue three fundamental objectives: smart growth - developing a knowledge and innovation-based economy, sustainable growth - promoting a more competitive and greener economy, in which resources are used more efficiently and inclusive growth - encouraging or high employment of the workforce, to ensure socia...

The purpose of this study is to highlight the flavour compounds found in tonic beverages obtained from plants with bioactive potential. Identifying these compounds through GC-FID (gas-chromatographic coupled with flame ionization detector) modern methods are leading to the appreciation of these beverages and the possibility of improving the proposed recipes. Six drinks rated B1, B2, B3, B4, B5, B6 made from indigenous plants; the plants were dried at 65 пїЅ C, macerated in 50% vol. ethanol for three days in a rati...

The purpose of this study was to determine an optimal variant for producing skimmed stirred yoghurt with chia powder. Three variants of product with chia powder at levels of 0.3%, 0.5%, respectively 0.7% and two control samples have been manufactured. Chia was used due to its remarkable content in fibre, ?-3 and ?-6 fatty acids, polyphenols, which are essential compounds for a healthy human body. The physicalchemical parameters (acidity, pH, dry matter) and rheological properties of yogurts samples were determined...

In the present study, low-fat muffins in which butter has been replaced at different levels (50% and 100% respectively) with pumpkin seeds powder were prepared. The valuable content of the pumpkin seed powder in proteins, fibres, vitamins, minerals and its good sustainability are important reasons for adding this ingredient in the food products. The physical-chemical parameters: weight, moisture, moisture loss, volume and specific volume were determined during storage period. Minerals content was carried out by us...

This work aims to analyze in terms of phenolic compounds of beverages obtained from indigenous plants, plants that are known in the specialized literature as being rich in bioactive compounds. Frum (2016) developed the identification method of the phenolic compounds, and this was based on a HPLC system, produced by Agilent Technologies 1200 Series, equipped with degasser, quaternary pump, DAD detector, automatic sampler with thermostat and column compartment equipped with thermostat. The measurements that were mad...
