In this study, ethanol extracts, ethyl acetate extracts and chloroform extracts of olive leaves, pomaces and virgin oil of picual and coratina cultivars were examined for their antioxidant activities. Coratina pomace ethanol extract had higher antioxidant activity(99.90%)than α-tocopherol (80.40%). Coratina pomace extracts had 97 mg gallic acid/g dried sample total phenols and 23.83 mg rutin acid/g dried sample total flavonoids. E-vanillic, salicylic, pyrogallol, benzoic acid, and catechin were the most abundant phenolic compounds in coratina pomace ethanol extract which represented 82.65% of the total phenolic compounds. Naringin, luteolin, hispertin, and quercetin were the most abundant flavonoid compounds in coratina pomace ethanol extract which represented 85.82% of the total flavonoids compounds. The coratina pomace ethanol extract had 7.53 h induction period of sunflower oil which represented 92.75% of α-tocopherol. Therefore, coratina pomace ethanol extract was selected for improving the shelf-life of carp fillets and carp burgers during storage at 5°C for 16 days. Carp fillets treated with coratina pomace ethanol extract at the concentration of 250 ppm and dipping time of 30 min and stored at 5°C for 16 days had lower TBA values, total bacteria, psychrophilic bacteria, lipolytic bacteria, proteolytic bacteria, total yeast and mold counts and rancid odor (described as very slight) as compared with the untreated sample (described as very strong). Fat retention and juiciness of carp fillets were increased and moisture retention and shrinkage decreased, however, the cooking yield was not affected. Carp burgers treated with coratina pomace ethanol extract at the concentration of 250 ppm and dipping time of 30 min and stored at 5°C for 16 days had lower moisture content, TBA values, total bacteria, psychrophilic bacteria, lipolytic bacteria, proteolytic bacteria and total yeast and mold counts than untreated sample. However, crude protein, crude fat, total ash and total carbohydrate contents had an opposite trend. Carp burgers stored at 5°C for 16 days in nitrogen packaging condition had lower mean TBA values, total carbohydrate than carp burgers stored in air packaging condition either in uncooked or cooked burgers. However, moisture, crude fat, total ash and crude protein contents had opposite trend. The total aerobic bacteria and psychrophilic bacteria counts were reduced by the cooking process either with air or nitrogen packaging conditions. However, lipolytic bacteria, proteolytic bacteria and total yeast and mold counts were inhibited by the cooking process. The uncooked carp burgers had mean rating scores ranged between like moderately (7.0) and like very much (8.0). However, cooked burgers had mean rating scores ranged between neither like nor dislike (5.26) and like moderately (7.0).

Wheat is an important part of the daily diet of millions of people but wheat products consumed in various forms are also responsible for food allergies. This investigation was carried out to study the ability of production of gluten – free bakery products from composite flour types, after study the effect of their chemical and rheological properties on the cupcake and fino bread quality. Utilization of legumes and germinated seeds (which are considered important sources of different nutrients) in gluten – free bakery production aimed to increase their nutritional and biological value. Some materials such as hydrocolloids and (gums) have been used to imitate the viscoelastic properties of gluten. The hedonic scores of all the cupcakes and fino bread were generally high indicating a strong (p ≤ 0.05) consumer appeal for wheat flour and some samples of composite flours. The results showed that cakes and fino bread produced from composite flours had excellent chemical composition and high biological values. From the results we could concluded that some of composite flours were suitable for cupcake and fino bread production.
