The qualities of the type 500 flours for the production of bread imported in the republic of Kosovo
The quality of baking products is dependent on wheat respectively flour. During the grinding process there are produced many types of flour which can be divided into different types according to the mineral content. The typical flour for making bread is from the type 500 flour so its quality has a special place in the industry of bread production.
The analyzed flour is an import to Republic of Kosovo. From the results that we have gotten we can see that the humidity level of the flour is in between the allowed boundaries at 13.238±1.08%, the acidity degree is also in between the allowed boundaries at 1.765±0.087%, the mineral matter content is characteristic to the type 500 flour at 0.48±0.02 of which we have iron at 40.49±14.67%. The proteins as a key factor to the baking technology are at a lower content at 11.016±0.33% but the content of wet gluten is at an average of 25.675±0.47%, also the sediment value as a factor on bread quality is at an average of 35.85±1.5cm3
Chemical composition and nutritional value of Raspberry fruit (Rubus idaeus L.)
Raspberries fruits (Rubus idaeus L.) as important part of our diet are known for their sensory and nutritional characteristics, because of high content of essential nutrients that are beneficial for biological activity in human health. A high consumption of plant foods, such as raspberries, appears to decrease the risk of obesity, diabetes, heart disease, and overall mortality. It can also promote a healthy complexion, increased energy, and overall lower weight. Nutritional quality was analyzed through by chemical parameter of fresh raspberry samples from plantation in Kosovo area at the ripe stage. The following quality parameters were determined in the raspberryâs fruits: pH, dry matter, total soluble solids (TSS/âŠBrix), total acidity (TA), TSS/TA ratio, total sugars, reducing sugars, sucrose, vitamin C, protein, and lipids. Results can be used to inform potential raspberry farmers about the nutritional qualities and consumer preferences for raspberries. The rich nutritional composition of the studied fruits makes them a very special diet. All statistical analysis performed using the MS Excel program and SPSS 22.0 statistics software
Effect of extraction solvent on bioactive compounds and antioxidant activity of Achillea millefolium L. grown in Kosovo region
Achillea millefolium L. is a plant of the family Asteraceae, commonly known as yarrow, which grows and is being distributed in countries of Europe. Achillea millefolium L. has been traditionally used in medicine. The medical properties of Achillea millefolium L. have been known for a long time. This study aims at assessments of the total phenolic content, flavonoid content and antioxidant activity of Achillea millefolium L. flowers, grown in Kosovo region. Solvent extracts with different polarity (aqueous, ethanol-EtOH, methanol-MeOH, ethyl acetate-EtOAc, acetone) from the flowers of Achillea millefolium L. are analyzed. The total phenolic and flavonoid quantities were analyzed by using FolinâCiocalteuâs and AlCl3 reagents, respectively. The antioxidant activity was assessed by DPPH in vitro assay methods. The extract obtained by methanol showed the highest total antioxidant activity and DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity (51.9±0.3 ÎŒMol/g). The same extract also exhibited the highest phenolic content (52.6±0.3 mg GAE/g) and the highest flavonoid content (27.8±0.2 mg CE/g). Further studies need the assessment to quantify and isolate the phytochemicals from Achillea millefolium L. flowers, grown within the Kosovo region, which might serve as a cheap natural antioxidants in food and drug industry
Environmentally Friendly Extraction of Bioactive Compounds from Rosa canina L. fruits Using Deep Eutectic Solvent (DES) as Green Extraction Media
In this study, the green extraction of Bioactive compounds and antioxidant activity from Rosehip (Rosa canina L.) fruits was investigated using ultrasound-assisted extraction combined with deep eutectic solvents (DES). A deep eutectic solvent-based on citric acid has been specially designed.

Determination of Physico-Chemical Analysis of Milk from Three Different Regions
One of the primary foods for human health is milk and dairy products. In dairy industry measuring the quality of milk is crucial for procesing and production of dairy products. Determination of milk quality is done through physico-chemical analysis. Out of 70 milk samples were analyzed from the region of Malisheva, Rugova and Skenderaj. The average fat results in order were 3.98%, 4.06% and 3.92% respectively, the average pH results in order were 7.12, 7.17 and 7.09 respectively. The results of physico-chemical analyzes can be used for various reasons such as milk payment and is of great importance in the processing of milk into dairy products
The Distribution of Minerals in Crucial Parts of Mountain tea (Sideritis scardica Griseb.)
The aim of this study was the determination of mineral content in spontaneous flowering stems and rosette leaves of mountain tea (Sideritis scardica Griseb.) collected in four different localities in North Macedonia. The plant material was air-dried, packed in paper bags, and kept in a dark and cold place until analysis. Samples were digested in a microwave system by the wet digestion method. The minerals were determined by the application of inductively coupled plasmaâatomic emission spectrometry (ICP-AES) and inductively coupled plasmaâmass spectrometry (ICP-MS). The rosette leaves exhibit a very similar mineral content profile to the flowering stems of S. scardica, and accordingly can be recommended as a plant material of this endemic aromatic plant

Optimized conditions for extraction, quantification and detection of bioactive compound from Nettle (Urtica dioica L.) using the deep eutectic solvents, ultra-sonication and liquid chromatography-mass spectrometry (LC-DAD-ESI-MS/MS)
ABSTRACTThe bioactive constituents of Nettle (Urtica dioica L.) plants were extracted by green and environmentally friendly methods using several deep eutectic solvents (DESs) followed by liquid chromatography-mass spectrometry separation and identification. To optimize the extraction process, bio-solvents composed of organic acids such as hydrogen bond donors (HBD) and mannitol/menthol/sugars as HBA were selected and coupled with ultrasound-assisted extraction. The maximum bioactive compound contents were TPC 2423âmg GAE/100âg, TFC 134.71âmg CE/100âg, and DPPH 1071.05âmol TE/mL. The optimum extraction parameters to achieve the highest values of phenolic compounds from Nettle (Urtica dioica L.) via UAE-DES were obtained at an extraction temperature 70°C, extraction time of 30âmin, and water addition on DES 20%. The ideal experimental conditions were confirmed using the Central Composite Design (CCD) of the Response Surface Methodology (RSM) model to analyze the significance of extraction parameters demonstrating high prediction levels of the bioactive compounds. Liquid chromatography coupled with diode array detection and electrospray ionization tandem mass spectrometry (LC-DAD-ESI-MS/MS) was used to identify the extracts. The results showed that quercetin-3-O-rutinoside, 5-ocaffeoylquinic acid, and caffeoyl malic acid were the three compounds with the highest abundance. For the first time, the extraction of bioactive compounds from nettle using a food-grade DES that contains GRAS components is reported. According to these findings, the best solvent for extracting bioactive substances for food-grade applications is DESCAMAL (citric acid/maltose)
