BACKGROUND Pectin-rich wastes, such as citrus pulp and sugar beet pulp, are produced in considerable amounts by the juice and sugar industry and could be used as raw materials for biorefineries. One possible process in such biorefineries is the hydrolysis of these wastes and the subsequent production of ethanol. However, the ethanol-producing organism of choice, Saccharomyces cerevisiae, is not...

Background & Aims of the Study: Today, the environment pollution with heavy metals has increased. It is important to study various types of pollutions specially those regarding fruits. The effect of pollutions on food safety for human consumption is a global concern.  This study was conducted for health assessment of heavy metals pollution (cadmium, lead, and arsenic) in c...

The objective of the current study was to evaluate the effects of supplement type and feeding frequency on performance, voluntary forage intake, and physiological responses of yearling beef steers. Twenty-four Brahman x British steers were stratified by initial body weight (BW) and randomly allocated to 12 pens (two steers/pen). Pens were randomly assigned to one of three treatments: 1) molasse...

Temperature pretreatment is one of the most important factors which significantly affects postharvest quality citrus fruit. In this study, late-ripening Valencia orange (citrus sinensis) fruits were used to investigate effect short-term treatment at low (6°C), room (20°C), and high (40°C) temperatures on fruit quality. Our results revealed that both room-temperature treatments maintained conten...

Citrus fruit processing industries produce a vast quantity of waste materials as peel and pulp that are not handled properly. In present study, waste generated from citrus has been used for extraction of cellulose and nanocellulose. The aggregated cellulose, derived after alkaline treatment, was acid hydrolysed; resulted in reduction of the size of cellulose fibre. The cellulose showed amorphou...

Citrus by-products are the processing wastes generated after citrus juice extraction and constitute about 50% of fresh fruit weight. This solid residue is comprised of the peel (flavedo and albedo), pulp (juice sac residue), rag (membranes and cores) and seeds. The disposal of fresh peels is becoming a major problem for many factories. Usually, citrus juice industries dry the residue and it is ...
