The ability of three solution of edible films (6% gelatin without orange peel powder, 6% gelatin with 0.1% orange peel powder, 6% gelatin with 0.5% orange peel powder, 6% gelatin with 1% orange peel powder), to extend shelf -life of cupcake was examined during refrigeration storage. This coating was moisture saving, results of sensory and appearance evaluations of the filmed cupcake after storage were that the three samples have shown incorporeal prevalence in saving the sensorial properties with an acceptance degree of 6.75/7 in comparison with the standard sample that failed its sensorial properties after storage for 7 days, which gained low sensory acceptability. New edible coating composition was found to increase storage age and decrease microbial growth. Moreover, moisture was held to keep cakes undried. Membranes have shown high blocking towards water vapor and oxygen. There is significantly (P0.05) reducing in bacteria and there no growth of any mold or yeast during storage time in the three filmed cupcake samples. Peroxide value of samples at beginning of the experiment was 2.79 ml.eq./kg fat, after 1 week in refrigerating storage there is increasing in control sample up to 10.35 (ml.eq./kg fat) while the three samples of (0.1, 0.5, 1.0) % orange peel powder that showed a little increase in peroxide value reached 3.60, 3.75, 4.80 (ml.eq./kg fat) respectively, which indicated the antioxidant activity of orange peel powder. Key words: Edible Film Component, Microbialinhibition, Oxidative Activity, Orange Peel Powder Introduction Orange is the most commercial fruit of the genus Citrus of the family Rutaceae which have leathery and oily rinds and edible juicy inner flesh with delicious taste. The fruit I rich in Vitamins A, B and C and a good source of beta-carotene, folate, pectin and minerals such as potassium, iron, selenium, iodine, phosphorus, manganese, sodium, chlorine and zinc. Furthermore, orange peel contains more than 170 different phytonutrients and more than 60 flavonoids combinations which highly evaluated as anti-cancer, anti-oxidants and anti-microbial agents (Al-Ani, 1989; Obidi et al., 2015 and Saonere Suryawanshi, 2011). Several materials had been employed in film foaming such as Gelatin (A.O.A.C., 2008), Agar (E406) (Barreto et al., 2003). Generally, edible films processing employed polysaccharides or protein at 10-16%. Many plasticizers should also utilize to import reliable flexibility, elasticity and breakage resistance during usage and storage (Williams and Phillips, 2000). The most common plasticizers used in film preparation include glycerol, polyethylene, sorbitol, sucrose and water (Stanley, 1995; Myllärinen et al., 2002; Jagannath et al., 2006; Cerqueira et al., 2009; Bourtoom et al., 2006 and Veiga-Santos et al., 2007). A new generation of edible films were designed to increase their functional properties as incorporating natural antimicrobial and antioxidants agents, enzymes and other components such as probiotics, minerals and vitamins (Bifani et al., 2007; Vargas et al., 2008). Films with antimicrobial and antioxidants properties are characterized with slowing microbial penetration via films and enhancing nutritional values of coated foods (Hao Tian et al., 2015 and Kierman, 2008). The aim of present investigation was to assess incorporating orange peel in edible films manufacture. The prepared mixtures were applied to cupcake by dipping and brushing. Evaluation of the antimicrobial and antioxidant capacity of the manufactured product during storage at (6±2) °C.
