The increasing amounts of agro-food waste generated globally represent a major challenge for environmental protection and sustainable development. Among these, onion peels resulting from processing, storage, and commercialization constitute an important source of bioactive compounds such as flavonoids, polyphenols, quercetin, and sulfur-containing compounds, with high potential for valorization in the field of green nanotechnologies. The study aims to valorize the extract obtained from onion peels in the green syn...

Quince (Cydonia oblonga) is a fruit of notable nutritional and therapeutic value, largely due to its high content of bioactive compounds. This study presents a comprehensive evaluation of the nutritional composition, antioxidant capacity, and polyphenolic profile of quince fruits Through standardized and rigorous physico-chemical analyses, the fruit was shown to possess a complex nutritional profile, with a particularly high concentration of vitamin C. Additionally, quince exhibited strong antioxidant activity, wh...

The objective of this work was to evaluate the physical, chemical and rhelogical characteristics of vegetable milk of soybean (soymilk homemade prepared, and some types of soymilk purchased from Romanian supermarkets). Soymilk is an alternative to dairy products and it has long been a traditional drink in China, Japan and other parts of Asia. The soybean (Glycine max) is the most important bean in the world, providing a wide range of vegetable proteins. Soybean is an important source of many bioactive compounds, w...

Tomatoes (Solanum Lycopersicum) are fruits rich in bioactive substances, especially compounds with antioxidant characteristics. Tomato fruits are a source of vitamin C, having beneficial properties for health. Current indications lead us to the conclusion that tomato fruits are potential candidates for the study of bioactivity, as well as for functionally developed fruits. The activity of these bioactive compounds is to combat the activity of free radicals. Tomatoes are the most popular vegetable crop in the world...

Taking into account the fact that by fortifying chocolate, more nutritious and healthier chocolates are obtained, in this work we set out to obtain an assortment of milk chocolate with the addition of chicken eggshell powder and to evaluate its mineral intake. Practically, the purpose of this experiment is the superior valorization of eggshell waste from household activities as a mineral fortification for milk chocolate. Four types of milk chocolates were prepared with the addition of 0, 1, 2 and 4% chicken eggshe...

The purpose of this study was to demonstrate the role played by different wastewater treatment technologies in the dairy industry in the context of the challenges of sustainable development: water scarcity and conservation of water resources, the constant growth of the population and the costs of wastewater treatment in centralized systems, increasing constraints and stricter environmental protection regulations. In this sense, the efficiency of wastewater treatment plants belonging to a number of 8 factories was ...

This paper presents the preliminary results obtained for the determination of some nutritional parameters of homemade chocolate fortified with nettle powder (NP) obtained from young nettle leaves grown in spontaneous flora, in pollution-free areas. 4 types of homemade chocolate with the addition of 2.5 - 10 % NP and a control chocolate (without the addition of NP) were prepared. Samples were analyzed from the proximate composition and mineral content point of view. The obtained preliminary results show that the ch...

The Fourier Transform Infrared (FT-IR) spectroscopy is one of the suitable experimental tools for analysis of urinary calculi constituents. However, interpretation of infrared spectra for quantifying urinary calculus constituents in mixtures is difficult, requiring expert knowledge by trained technicians. The development of automated methods for determining the composition of uroconcrements is very important since it can facilitate the determination of the factors which influence the occurrence of calculi in urina...

Increasing tendency for fresh food - fruits, vegetables, and herbs - consumption worldwide and also in our country shows the important role they play in the diet. In this case, it is not only good looks, nice color or taste and aromas that are considered to be important, but especially their nutritional value, rich in sugars, vitamins and minerals necessary in the diet of the human body. They also have the advantage to be fit for consumption without any processing which could reduce their nutritional value. The pu...

The fruit represents the group of foods with vegetable origin, very precious from nutritional point of view, rich in carbohydrates, cellulose, minerals and organic acids, needed daily for the human body. A popular form often used for preserving fruit in cold periods, are fruit compotes which occupies an important place in our daily diet. Pineapples and mango fruit are consumed fresh, cooked, juiced and also can be preserved. The aim of the study was to evaluate some physicochemical characteristics (pH, total solub...
