Physical-chemical analyzes of standard pear cultivars grown in Turkey with Turkish varieties that were domesticated in Bosnia and Herzegovina

The assortment of pear in BiH is very diverse. A significant contribution to the cultivation of a large number of sorts and varieties of pears was contributed by the constant migration of people who carried and planted fruit trees with them. The largest number of fruit varieties and pears in BiH came from two directions. From the east with the Ottoman Empire and from the west with the arrival of the Austro-Hungarian Empire. The pear, as a fruit species, takes a significant place in fruit production, considering that it can be grown in a wide range of cli-matic conditions, different ripen times, from early summer to late autumn, and multi-purpose use.The fact is that many varieties of pears arrived from Turkey centuries ago and that they were preserved and retained in BiH. This fact is corroborated by the names of variety / Karamut, Jeribasma, Black Izmir and others The paper analyzes the following parameters: pH, total acidity in mmol / 100 g, pectic substance% Ca-pectinate, raw fiber (%), vitamin C in mg / 100 gr, natural invert (%), total invert (%), total phenols in mg / 100 g of fruit, soluble dry matter (° Brix).The aim of this paper is to determine the usable value and, therefore, the possibility of introducing standard cultivars grown in Turkey to our area through physical and chemical analysis of fruits of indigenous and standard pear trees. The juice of the tested variety has a lower pH value than the reference values. Low supply of Ca pectate. Vitamin C content is above average. The tested varieties in terms of soluble dry matter content meet the applicable legal framework

Comparative analysis of the antioxidant capacity of some natural and synthetic antioxidants added to palm oil

Various synthetic and natural antioxidants are used to reduce oxidation and its negative impact on the oil during the food frying process. Considering that some studies show the negative impact of synthetic antioxidants on the health of consumers, natural alternatives are being used more and more. BHA and BHT are synthetic antioxidants that are widely used in the food industry and a large number of natural compounds such as phenols, anthocyanins, flavonoids, vitamins, etc. show antioxidant properties. In this study, the antioxidant capacity of oregano and rosemary essential oil was tested and compared with the antioxidant capacity of BHA and BHT. The antioxidant capacity was evaluated by the removal of DPPH radicals and by iron reduction (FRAP). The results of this study showed that the studied essential oils exhibited antioxidant capacity. These oils have a high antioxidant capacity, however, compared to synthetic antioxidants, they show a significantly lower antioxidant capacity but they can be used as natural antioxidants during food processing

IMPACT OF HYBRIDS OF FATTENED CHICKENS ON SLAUGHTER INDICATORS AND CHEMICAL COMPOSITION OF MEAT

Zbog povoljnog kemijskog sastava pilećeg mesa (nizak sadržaja masti a veliki udio visokovrijednih proteina) i zbog njegove pogodnosti za suvremenu prehranu ljudi, na tržištu se sve više traže dijelovi pilećeg trupa. Stoga se naglasak u proizvodnji pilećeg mesa stavlja na kvalitetu i odnos osnovnih dijelova trupa (prsa i file bez kostiju, batak i zabatak). Na području Bosne i Hercegovine za proizvodnju pilećeg mesa koriste se mnogobrojni komercijalni hibridi (brojleri) među kojima su najzastupljeniji Cobb 500, Hybro PG i Ross 308. Svaki od navedenih hibrida ima različite proizvodne performanse. Primarni cilj ovog rada je istraživanje performansi hibrida tovnih pilića (Cobb 500, Hybro PG i Ross 308) pri određenim uvjetima tova, klaoničkih pokazatelja i utvrđivanje kemijskog sastava mesa kao jednog od čimbenika kvalitete pilećeg mesa. U toku istraživanja utvrđeni su sljedeći proizvodni pokazatelji: konverzije hrane, tjelesne mase pokusnih pilića na farmi, kalo transporta, mase nejestivih i jestivih dijelova kamo pripadaju trup i iznutrice, kalo hlađenja, i mase dobivenog \u27\u27grill\u27\u27 mesa. Kemijska analiza pilećeg mesa obuhvatila je određivanje sadržaja suhe tvari, proteina, masti, pepela, i vode na uzorcima bijelog i crvenog mesa sva tri ispitivana hibrida. Svi rezultati dobiveni u toku istraživanja su statistički obrađeni. Statističkom analizom rezultata istraživanja utvrđeno je da hibrid Ross 308 ima povoljnije nutritivne karakteristike, najveći sadržaj proteina (p<0,05), a najmanji sadržaj masti (p<0,05) u odnosu na hibride Cobb 500 i Hybro PG. Kod analize klaoničkih pokazatelja, rezultati su pokazali da Hybro PG ima najveću vrijednost tjelesne mase pred klanje, kao i najveću vrijednost mase \u27\u27grill\u27\u27 mesa.Because of its favourable chemical composition that is due to the low fat content, and high percentage of high-quality protein, and the benefits of chicken meat for modern human nutrition, on the market increasingly are popular chicken carcass parts. So the emphasis in the production of chicken meat is placed on quality and yield of the basic parts of the body (breast and boneless fillets, thighs and drumsticks). In Bosnia and Herzegovina in the production of chicken meat many commercial hybrids (broilers) are used, predominately Cobb 500, Hybro PG and Ross 308. Each of these hybrids has different production performance. The primary objective of this paper is to study the performance of hybrids (Cobb 500, Hybro PG and Ross 308) under certain conditions of fattening, slaughter parameters and chemical composition as a factor in meat quality. During the research and analysis of the results of the experiment the following values were set: feed conversion, weight of sample chickens on the farm, transport outage, mass non-edible parts, the mass of edible parts where they belong: chicken carcass, offal, chilling outage, and “grill” meat. Chemical analysis of chicken meat included the determination of dry matter, protein, fat, ash, and water of samples from the white and red meat of all three hybrids. All the results obtained during the study were statistically analyzed. Statistical analysis of results showed that the hybrid Ross 308 had a favourable nutritional characteristics, the highest protein content (p<0,05) and the lowest fat content (p<0,05) compared to hybrids Cobb 500 and Hybro PG. When analyzing slaughter indicators, the results showed that Hybro PG had the highest value of body weight before slaughter, and the highest value of the mass grill meat

NUTRITIONAL TREATMENT OF GOUT

Urični arthritis (giht, ulozi) je sistemska bolest, a najčešće se ispoljava na zglobovima. Nastaje kao posljedica povećane koncentracije urične kiseline u krvi koja kristalizira u formi mononatrijevog urata, akumulirajući se u zglobovima, tetivama, te u okolnim tkivima. Nastali kristali pokreću lokalne imunološki posredovane upalne procese u tkivima. Urična kiselina nastaje složenom endogenom enzimski posredovanom razgradnjom purina ali i drugih jednostavnih metabolita. Purini su komponente nukleoproteina, a nalaze se u različitim količinama u većini vrsta hrane. Ograničenje egzogenog unosa purina sa hranom smanjuje mogućnosti stvaranja urične kiseline, reducira metabolički stres i nastanak upalnih procesa. Prema nivou sadržaja purina hrana se može podijeliti na hranu sa visokim sadržajem (100 do 1000 mg purina/100 g), hranu sa srednjim (10 do 100 mg purina /100 g) i hranu sa niskim sadržajem purina. Način ishrane samo dijelom može uticati na tretman bolesti. Tradicionalno, dijeta sa vrlo niskim egzogenim unosom purina preporučuje se u akutnim stanjima uz medicinski tretman. Nutritivni tretman bolesti treba biti bazirana na smanjenju tjelesne mase, primjerenom unosu ugljičnih hidrata, smanjenom unosu zasićenih masnoća i holesterola, primjerenom u unosu proteina, povećanim unosom tekućine i eliminacijom konzumiranja alkohola. Nutritivni tretman može dati značajanu podršku medicinskom tretmanu bolesti.Uric arthritis (gout) is a systemic disease, and usually manifests in the joints. Occurs as a result of increased concentrations of uric acid in the blood, which crystallizes in the form of mono sodium urate, accumulates in the joints, tendons, and in the surrounding tissues. The resulting crystals promote local immune-mediated inflammatory processes in tissues. Uric acid is formed by complex endogenous enzyme mediated degradation of purines and other simple metabolites. Purines are components of the nucleoprotein, and are found in varying amounts in most foods. Restriction of dietary purine intake of food decreases the ability to create uric acid, reducing metabolic stress and the occurrence of inflammatory processes. According to the level of purine content foods can be divided into foods with a high content 100 to 1000 mg purine/100 g), food with medium (10 to 100 mg purine/100 g) and foods that are low in purine. Only part of the diet may affect the treatment of disease. Traditionally, diets with very low intake of exogenous purine is recommended in acute situations with medical treatment. Nutritional treatment of disease should be based on weight reduction, adequate intake of carbohydrates, reduced intake of saturated fat and cholesterol, the appropriate protein, increased intake of fluids and elimination of alcohol consumption. Nutritional treatment can provide significant support to the medical treatment of disease
