Helaly, Ekbal | Ali, Mahmoud A | Ghazala, Naglaa
This study was conducted to investigate the effects of five essential oils (garlic, Allium sativum; camphor, Cinnamomum camphor; menthol, Mentha sp.; cinnamon, Cinnamomum erum; and clove, Dianthus sp.) on wax moth larvae and adult honeybee workers under laboratory conditions. Cinnamon, garlic, menthol, clove, and camphor oils were found to be highly effective against wax moth larvae, with 100 percent mortality achieved after 48 and 96 hours for cinnamon and garlic oils respectively, and after 120 hours for clove and mint oils. Camphor oil provided 96.60% accumulative mortality after 120 hrs. Moreover, all the essential oils were highly safe for adult honeybee workers under laboratory conditions. Accumulative corrected mortality rates after 72 hr were 15.96, 9.02, 13.18, 29.16, and 8.88% for treatments with cinnamon, clove, camphor, mint, and garlic oils respectively.

Еssеntial oils (ЕOs) from cinnamon (Cinnamon zylanicum), clovе (Syzygium aromaticum) camphor (Еucalyptus globulus), and rockеt (Еruca sativa), wеrе еvaluatеd for thеir botryocidal еffеct. In-vitro, Botrytis cinеrеa was еxposеd to 4 diffеrеnt concеntrations of ЕOs, using thrее diffеrеnt tеchniquеs, i.е. amеndеd mеdium, vapourisation, and volatilising. Cinnamon and clovе ЕOs wеrе thе highеst tеstеd concеntrations found to bе thе most еffеctivе in all tеchniquеs which complеtеly inhibitеd 100% of radial growth for B. cinеrеa in vitro. A post-harvеst trial to control grеy mould on grapе bunchеs of Flamе sееdlеss and Supеrior sееdlеss cvs. were conductеd using cinnamon and clovе oils in sеasons 2014 and 2015. Both of the two ЕOs wеrе usеd at concеntrations of 25, 50 and 100 µL./L-1air v/v, еxposеd as vapour trеatmеnt significantly supprеssеd grеy mould during thе cold-storagе. Thеrе was not a significancе diffеrеncеs obsеrvеd among both ЕOs trеatmеnts. Howеvеr, cinnamon at 100 µL.1L-1air v/v was thе most еffеctivе trеatmеnt to control grеy mould of both grapе cultivars

Natural antioxidants have gained considerable interest in recent years for their role in preventing the auto oxidation of fats, oils and fat containing food products. In this study, six spices containing natural antioxidants were evaluated for their re-tarding fat oxidation compared to butylated hy-droxyl toluene (BHT). The yield obtained from water extract of the tested spices ranged between 20% and 50 %. Carob gave the highest yield fol-lowed by anise and cinnamon, then caraway and fennel, while ginger gave the lowest yield .The free radical scavenging activities measured by 2-diphenyl-1-picryl-hydrazyl (DPPH) were 88.08%, 81.69%, 79.62% , 78.93% , 73.06% , and 71.50 % for cinnamon, anise, carob, caraway ginger, and fennel, respectively at concentration of 2250 μg/ml. Cinnamon showed higher antioxidant ac-tivity on linoleic acid oxidation than BHT fol-lowed by anise, carob and ginger. While, fennel and caraway recorded closely antioxidant activity to that of BHT at low concentration of 100 μg/ml. Total phenolic content of the tested spices varied ranging from 11.19 to 22.95 mg as gallic acid / gm dry extract in carob and caraway, respectively. Depending upon the sensory evaluation of crois-sant containing different levels of tested spices, a concentration of 1.5% of anise, caraway fennel and cinnamon was chosen, while the chosen con-centration of ginger was 2.5% and carob was 1% for testing their effectiveness against oxidation of lipid in croissant. However, a concentration of 2% of anise, fennel, ginger and carob was chosen while, the chosen concentration of caraway and cinnamon was 1% for testing their effectiveness against oxidation of lipid in filling cream. Addi-tion of tested spices gave an excellent antioxidant effect on croissant and filling cream compared with the effect of BHT. The increase in both per-oxide and acid values after 14 and 28 days respec-tively were lower than of control and BHT. Carob, ginger, caraway and cinnamon were more effec-tive in controlling lipid oxidation during storage. In conclusion addition of tested spices as sources of effective natural antioxidants retarded lipid oxi-dation and maintain the quality of croissant and filling cream during storage.

Soliman, A.E.M.
Iron deficiency anemia is considered one of prevalent patients in developing countries, whereas it is well known that wheat flour is deficient in iron, hence, in this study wheat flour (72%) extraction fortified with celery seeds and cinnamon bark meal individually as a natural sources of iron at levels 5, 7.5 and 10 g/100 g wheat flour and preparation of biscuit samples. Iron content in wheat flour, celery seeds and cinnamon were determined. Biscuit samples were sensory evaluated and baking quality tested. Total iron and available iron were determined in biscuit samples. Biological evaluation for experimental rats designed and histopathological examination was tested for heart organ of rats. The results showed that wheat flour, celery seeds and cinnamon contained from iron 1.98, 57 and 50 mg/100 g respectively. Total iron and available iron increased in biscuit samples by increasing celery seeds and cinnamon additives compared with unfortified biscuits (control). Sensory evaluation of biscuit samples showed slight decrease in color, crunchiness and appearance while odor and taste significantly improved by increasing celery seeds and cinnamon additives compared with control. Baking quality of biscuit samples indicated increasing in weight, while volume, diameter and thickness slightly decreased by increasing celery seeds and cinnamon additives compared with control. Biological evaluation revealed that mean values of hemoglobin, hematocrit, red cell count, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, serum iron and serum ferritin significantly improved after 8 weeks in groups rats fed on biscuits fortified with celery seeds and cinnamon compared with control. histopathological overhaul declared amelioration in ogran heart for groups rats fed on biscuits fortified with celery seeds and cinnamoin compared with anemic control
