Whey is a significant environmental contaminant since its waste load is estimated to be 100-175 times more than that of an equivalent volume of household wastewater. It is estimated that around half of the whey produced is used for human or animal use, and the other half is released into the environment as waste water, which adds to pollution. Thus, in accordance with the guidelines established by the EU Green Deal Program, its valorisation through the development of health-promoting products is an important step ...

Whisky is one of the most consumed alcoholic beverages in the world obtained from cereals. By-product and waste management are considered significant economic and environmental issues in whisky production. The aim of this study was to assess the components of spent grain (draff) resulting from the only factory in the whisky industry in Romania. Spent grain consists of layers of peel, pericarp, and seeds with residual amounts of endosperm and aleurone from malt used as raw material. Spent grain was stored at -18 °C...

Malt is the essential raw material for beer production. Currently, in Europe the most used cereal for beer is barley due to its many advantages in the manufacture of malt. Recently, research has intensified to replace this raw material for beer with other cereals or pseudo-cereals. These include buckwheat which does not contain toxic prolamins to celiac disease patients. Buckwheat is an annual plant of Polygonaceae family and is produced in many countries for its characteristics such as high economic value, easily...

Acrylamide (AA) is a chemical contaminant that is formed in bakery products during baking in especially for those obtained from flour with a high extraction rate. There are several ways to reduce the level of AA in bakery products, one of them being the use of antioxidants in bread making. The present study aims to analyze the effects antioxidant addition, respectively a rosemary extract one, in various levels (0.02%, 0.1% and 0.5% on wheat flour of a high extraction rate of 1250 type) to obtain bread products, in...

The use of various ingredients in the formulation of yogurt, in order to diversify a dairy product particularly appreciated by consumers, is a constant concern for industry specialists. The paper proposes the use pumpkin seeds in the recipe of a classic yogurt, in order to improve its physico-chemical, textural and sensory characteristics. Pumpkin seeds, like other oilseeds, are in the attention of specialists because they are a very good source of proteins and dietary fibers. For the consumer, the increase in the...

In this paper we used the research done in a previous laboratory study in which we optimized the addition of seabuckthorn powder, rosehip powder and grape seed extract to the classic yogurt formulation. Yogurt with the best physicochemical and sensory properties was obtained by adding 1.5% rosehip powder and 0.5% grape seed extract, respectively 1.75% seabuckthorn powder and 0.25% grape seed extract to its manufacturing formulation. Prior to inoculation, the ingredients mixture was pasteurized at 85В°C for 30 minu...

Novel trends in the market of fermented dairy products are leading to obtain various products with high functional and nutritive but less energy value. The development of new fermented dairy products could be divided into two groups in order to: 1. obtain products with improved physicochemical characteristics, rheology, texture, microstructure and sensory properties; 2. obtain products with pronounced nutritive characteristics and functionality. Yogurt is a very popular dairy product in most countries, it is consi...

Particle size is an essential concept in flour milling which influences dough rheological properties and food product quality. The grape seeds flours (GSF) obtained by further grinding grape seeds vary in particle size and differ in chemical composition. Grape seeds selected from red wine pomace and wheat flour of a low extraction rate of 480 type were used in samples formulation. The objective of this work was to investigate the influence of different particle sizes and addition levels of grape seeds flour (GSF) ...

The aim of this paper was to investigate the effect of defatted rapeseed flour addition from which proteins were extracted (DRF) on quality characteristics of bread as a finished product by baking test, rheological and microstructural examination. The dough rheological properties were determined by using the Alveograph device and its microstructure was analyzed by using the epifluorescence light microscopy (EFLM). Also, there were conducted analyses on the bread quality prepared from composite flour (wheat flour 6...

Sea buckthorn (Hippophae rhamnoides L.) has gained worldwide researchers attention as a unique and valuable plant, primarily for its medicinal and nutritional potential. The berries can be capitalized by their processing in order to obtain derived alimentary products such as, e.g. juice and jam, as well as used for flavoring of dairy products. The dried sea buckthorn berries and leaves are used for tea. Lately, due to the fact that consumers are more open to information, so their level of awareness is higher, ther...

Yogurt is widely consumed as functional food because of the good taste and nutritional properties (rich in potassium, calcium, protein and vitamins), being an excellent vehicle to deliver probiotics to consumers. However, its enrichment with various physiologically active ingredients could provide specific health benefits beyond basic nutrition. The reason for incorporating the sea buckthorn powder (SBP) in yogurt was to enhance its functionality, considering the sea buckthorn content in non-digestible oligosaccha...

Worldwide, the yogurt is a very popular fermented dairy food and it is known for its health benefits, nutritional value and digestibility. The factors that influence the quality of yogurt are milk composition, dry matter content, the temperature and time at which pre-treatment of the milk is carried out, the type and the quantity of starter culture used, incubation temperature and storage conditions for the final product. A major problem in the production of yogurt is the whey separation. In the yogurt industry, s...
