GENETIÈKA OSNOVA KUKURUZNOG OKLASKA – MORFOLOŠKA<br />

GRAÐA, PROIZVODI I UPOTREBA<br />

Milica Radosavljeviæ<br />

Institut za kukuruz «Zemun Polje», Beograd-Zemun<br />

U Institutu za kukuruz razvijen je originalni tehnološki proces prerade kukuruznog<br />

oklaska kojim se dobijaju razlièiti lignocelulozni proizvodi namenjeni za upotrebu u<br />

razlièitim granama industrije, poljoprivredi i zaštiti ivotne sredine. Za kukuruzni<br />

oklasak kao vrednu prirodnoobnovljivu polaznu sirovinu za industrijsku preradu, kao i za<br />

ostale namene veoma je bitna njegova morfološka graða i zahteva se njegovo fizièko<br />

prilagoðavanje, odnosno mehanièko usitnjavanje, granuliranje i otprašivanje.<br />

U ovom radu su date morfološka graða oklaska dvadeset razlièitih ZP hibrida kukuruza,<br />

kao i fizièkohemijske karakteristike i hemijski sastav razlièitih frakcija oklaska dobijenih<br />

po originalnoj ZP tehnologiji. Pored toga, detaljno su opisane i zbirno prikazane<br />

moguænosti korišæenja kukuruznog oklaska.<br />

GENETIC BASE OF THE MAIZE COB - MORPHOLOGICAL<br />

STRUCTURE, PRODUCTS AND UTILISATION<br />

The original technological process of maize cob processing was developed at the Maize<br />

Research Institute, Zemun Polje. This process provides the production of different<br />

lignocellulose products intended for utilisation in various industrial sectors, agriculture<br />

and environmental protection. A morphological structure of maize cob as a valuable naturally<br />

renewable raw material for industrial processing and other purposes is very important<br />

and therefore it is necessary to physically adopt the cob for different purposes, i.e. its<br />

mechanical pulverisation, pelleting and air separation are required.<br />

This paper presents the morphological structure of cobs of twenty different ZP maize hybrids,<br />

as well as, physical and chemical properties and the chemical composition of various<br />

cob fractions produced by the original ZP technology. Besides, possibilities of maize<br />

cob utilisation are described in detail and summary presented.
