8.5 Effects of Fining on Antioxidative Activity of Merlot Wine Obtained with Increased Content of Stem and Seed Puškaš, Vladimir and Miljić, Uroš University of Novi Sad, Faculty of Technology, Blvd. cara Lazara 1, 21000 Novi Sad, Serbia <strong>Abstract</strong>: The structure and amount of phenolic compounds in the wine depend on the grape variety, agroecologic and vinification conditions. The influence of pomace enrichment with grape stems and seeds during maceration, as well as the effect of commonly used fining agents (albumin, bentonite, gelatine and PVPP) on antioxidative activity of Merlot red wines were investigated. Besides control wine, produced from pomace which contained original content of seeds, without stems, other wine samples were obtained from grape pomace supplemented by 50% of previously separated stem or by 120 g seed/kg. The antiradical activity of red wines towards DPPH • and hydroxyl ( • OH) radicals was determined by electron spin resonance (ESR) spectroscopy. Enriching of pomace with 120 g seeds/kg resulted in increase of antioxidative capacity of wine. In wine enriched with tannins and flavan-3-ols from the seeds, the DPPH • radicals were completely eliminated (AA DPPH •=100%), while stem addition scavenged 88.21% of these radicals (AA DPPH • of control wine was 83.73%). Regarding the scavenging capacity against hydroxyl radicals, supplementation of pomace with seeds increased this parameter for 20%, while stem was not so efficient (5% increase). Applied fining agents, except gelatin, showed insignificant (p=0.05) influence on DPPH • scavenging activity of all wine samples. On the other hand, antiradical activity towards hydroxyl radicals (AA• OH ) was mostly significantly changed after each fining treatment.

Bermet is made exclusively from grapes from hillside vineyards of mountain Fruška Gora (Vojvodina, Serbia) and it is enriched with up to 24 to 26 aromatic, medicinal herbs. Technology of Bermet production is passed down from generation to generation and its recipe was kept as a closely guarded secret. This rare wine is produced in limited quantities, only 15,000 to 20,000 bottles a year. This fact gives to the Bermet a special value and impressiveness. Nowadays, it is known that main medicinal plants included in Bermet production are: wormwood (Artemisia absinthium), yellow gentian (Gentiana lutea), anise (Pimpinella anisum), cinnamon (Cinnamomum zeylanicum), bitterbloom (Centaurium umbellatum), black mustard (Brassica nigra L), coriander (Coriandrum sativum), cloves (Syzygium aromaticum), carob (Ceratonia siliqua) and liquorice (Glycyrrhiza glabra). Besides these plants, orange and lemon peel, vanilla bars, dried figs and grape, as well as some quantities of nutmeg (Myristica fragrans), are added to Bermet. Pharmacological compounds from these plants have a powerful tonic, antioxidative, antiseptic, antidiarrheic and antipyretic effect. These plants are often used to remedy indigestion and gastric pain in Serbian folk medicine. They can be also used as a carminative and in regulation of the menstruation. Bermet, as a valuable herbal medicinal beverage, demonstrates the complementary effect of phenolic compounds from red wine and numerous pharmacological compounds from medicinal and aromatic plants added during its production. The aim of this paper was to emphasize the individual effect of these plants, in order to evaluate their contribution to the medicinal value of this aromatic wine.

8.7 Industrial Products from Indigenous Fruits of Balanites aegyptiaca (L.) with Emphasis on the Potentiality of Balanites Oil in the Treatment of Some Superficial Mycosis Osman N.A.A., Elhussein S.A.B., Toum A.M.A., Abdelrahman E.E.A., and Hussein I.H.A. 1 Faculty of Engineering & Technology, University of Gazira, Wad-Medani, Sudan. 2 Faculty of Industrial Sciences & Technology, Universiti Malaysia PAHANG (UMP). <strong>Abstract</strong>: Fruits of Balanites aegyptiaca were claimed as a potential source of steroidal sapogenins, raw materials for the partial synthesis of the important group of steroid drugs. The tree is indigenous to Sudan. Our research interests focused mainly on steroid constituents in fruitparts and fruit accessions. However, other fruit by-products were encountered. Thirteen accessions of Balanites fruit were analyzed for their sapogenin content using infra-red spectroscopic method. Most of the sapogenins of Balanites fruit reside in the mesocarp (64%), followed by kernel (25%), and epicarp (10%). However, on a tissue-weight basis, kernel tissue was richest (2.5-5.0%) in several accessions. The 25α- to 25β-sapogenin ratio varied according to the fruit part (tissue) and developmental stageFruit kernel of Balanites yield as by-product of extraction, an interesting oil fraction that was characterized to be good dermatophytes. The study of crude extract of the fruit kernel oil (BKO) showed activity against fungi that is responsible for some dermatophytes diseases. BKO was prepared after kernel was ground and extracted on a Soxhlet extractor with n-hexane and dried by a Rotary evaporator. Applied doses on infected skin can be used topically on morning and at night for a period of 1-5 weeks depending on the patient's age and the type of fungus causing the infection. A suggested Scheme for Balanites fruit processing for steroidal sapogenin and by-products was proposed. Key words: Balanites aegyptiaca, BKO, dermatophytes, steroidal sapogenin. 8.8 Swelling and Residue Studies on Biofilms Containing Mixture of Gelatin / K- Carrageenan as Biomedical Applications Zaher K., El Kolli. M., and Benmesli. S. Laboratoire des matériaux polymériques multiphasiques (LMPMP), Département de Génie des Procédés Faculté de Technologie, Université Ferhat ABBAS – Sétif. <strong>Abstract</strong>: In this study two types of dressings in the form of thin films were prepared from a mixture of two natural biopolymers, namely gelatin and қ - carrageenan. The protein and the polysaccharide were chosen because of their hydrosolubility and interactivity, respectively. Glutaraldehyde was also used to crosslink the films. Sodium azide (NaN 3 ), used to avoid bacterial contamination. The biopolymer-based films were prepared from a mixture of pectin and gelatin by casting using the following procedure. 2.5 grams of gelatin/ қ - carrageenan mixture at a ratio of 88/12 were dissolved in 50 ml distilled water and a small amount of sodium azide, which was added to each solution to prevent bacterial contamination. After allowing the grains to swell for 35 min, the mixture was placed in a water bath heated at 60°C under slow agitation for 40 min. Once the resulting solution became clear, three different samples (5 ml, 10 ml and 15 ml) were withdrawn from the mixture and poured separately into 8.5 cm diameter polystyrene boxes in order to obtain films with different thicknesses. These samples were then allowed to dry in free air at room temperature for 3 to 4 days. The resulting films were crosslinked by means of glutaraldehyde (GTA). Crosslinking was carried out by pouring 20 ml of the GTA solution onto the dry films and allowing the reaction to take place for 24 h. Finally, the crosslinked films were washed with distilled water and dried in free air at room temperature. It was found that crosslinking much increased the absorption capacity, reflecting the strong interactions that developed between gelatin and қ - carrageenan. The FTIR analysis also allowed us to identify the different functional groups through which gelatin and қ - carrageenan chemically interacted. The quantitative analysis of the residue by means of UV spectroscopy indicated that the films were biodegradable and therefore can be used for biomedical applications. Key words: Absorption capacity, dressing, gelatin, қ - carrageenan, residue. 132
