Svakim danom povećava se i broj potrošaĉazainteresovanih za konzumiranje hleba obogaćenog vlaknima. Za izradu hleba sa povećanim i visokim sadrţajemvlakana, korišćena su hemijski modifikovana prehrambena vlakna iz ekstrahovanih rezanaca šećerne repe, usitnjena ifrakcionisana. Uticaj vlakana na tehnološke parametre proizvodnje hleba praćen je promenom reoloških i pecivnihosobina testa. Razliĉit udeo vlakana (0%, 5%, 10% i 15%) dodavan je u osnovne sirovine za izradu testa kao zamenaza deo brašna i zapaţeno je da vlakna u testu negativno utiĉu na formiranje glutenskog matriksa, tako da je biloneophodno dodavati vitalni gluten za ojaĉavanje glutenske strukture. Pri istoj koliĉini vode dodate za zames testa, kaoi u testu bez dodataka, modifikovana vlakna utiĉu na povećanje parametara: konzistencije testa u 5. minutu,maksimalne konzistencije i vremena potrebnog za postizanje maksimalne konzistencije. Pravilnom korekcijomsirovinskog sastava i tehnoloških parametara proizvodnje, moţe se dobiti hleb sa 10 i 15% modifikovanih vlakana izšećerne repe koja ne sadrţe fitinsku kiselinu, po senzornim osobinama sliĉan je belom hlebu na koga su potrošaĉinavikli. Hleb sa vlaknima, ima promenjen nutritivni sastav i smanjenu energetsku vrednost, odnosno ima sve osobinefunkcionalnog proizvoda.","PeriodicalId":424249,"journal":{"name":"GLASNIK HEMIČARA, TEHNOLOGA I EKOLOGA REPUBLIKE SRPSKE","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130316139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Theabove-mentioned codes have become an inevitable part of any industrial product. The aim of this experiment was totest readability of different QR codes printed with screen printing with different mesh tread densities (140 threads/cmand 180 threads/cm). The QR codes were prepared in six different dimensions (1 cm2, 1.3 cm2, 1.6 cm2, 1.9 cm2, 2.2cm2 and 2.5 cm2) with three different types of content (textual message-SMS with 160 characters, short URL and longURL) on seven different substrates (paper 170g/m2, self-adhesive paper, PVC foil, white and yellow cotton cloth/fabric,aluminium sheet and glass plate). During the experiment D65 light source was used as a simulation of daylight. Wehave used Neo Reader software for QR code reading on HTC Desire phone, using the 5-megapixel camera andpossibility of autofocus. The results show improved readability with QR codes printed with screen mesh of 140threads/cm and with the reduction of carried information, i.e. the number of characters that QR codes consist of. Also,the problem with readability decreases when using substrates such as aluminium sheet or glass plate.","PeriodicalId":424249,"journal":{"name":"GLASNIK HEMIČARA, TEHNOLOGA I EKOLOGA REPUBLIKE SRPSKE","volume":"02 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127178988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
