In order to maintain color and texture, plant-origin edible coatings are advantageous to foodstuffs as an air and moisture barrier. In this study, hemicelluloses extracted from corn peels were used as the coating material on bananas stored at 4 °C. At the end of storage, no fungal decay was detected on coated bananas, whereas 20% of uncoated bananas (control) were infected. Samples coated with 1, 1.5 and 2% hemicellulose (HC) lost 3.6, 3.3 and 3.1 of their total weight, respectively, whereas the control group lost 5.1% of total weight. Hemicellulose coating also protected firmness of bananas (701.1 gf for coated and 509.6 gf for uncoated samples). Color measurements showed that lightness and yellowness of the coated bananas were preserved with negligible losses while uncoated samples turned brown at unacceptable level. Thus, this study showed that hemicelluloses can be alternatively used as the coating material on surface of fruits.

Effects of an edible coating, fungicide and cold storage on microbial spoilage of cherries
Yaman, O; Bayındırlı, Levent A. (2001-01-01)
The effects of an edible coating, i.e., Semperfresh (TM), fungicide, i.e., Imazalil, and cold storage on microbial spoilage of cherries were studied. Two group of cherries (Prunus avium) were coated just after harvest with 1% and 2% Semperfresh (TM) fruit coating. Two other group of cherries were treated with 75 ppm and 150 ppm concentrations of Imazalil and then coated with a 1% concentration of Semperfresh (TM) fruit coating. Half of the cherries from each of the above groups was stored at ambient tempera...
Effects of an edible coating and cold storage on shelf-life and quality of cherries
Yaman, O; Bayoindirli, L (2002-01-01)
The effects of an edible coating, i.e. Semperfresh(TM) and cold storage on shelf-life and duality of cherries there studied. Taro groups of cherries (Prunus avium) were coated just after harvest with 10 and 20 g/L Semperfresh(TM) fruit coating which is composed of sucrose esters of fatty acids, sodium carboxymethyl cellulose and mono-diglycerides of fatty-acids. Half of the cherries from each of the above groups was stored at ambient temperature (similar to30+/-3degreesC) and at 40-50% relative humidity, th...
Extraction and physicochemical characterization of insect oils obtained from Acheta Domesticus & Tenebrio Molitor
Uğur, Ahmet Erdem; Alpas, Hami; Department of Food Engineering (2019)
Edible insects have become one of the most attracted and attention-grabbing alternative food sources in recent years due to the constituents that include proteins, oils, carbohydrates, minerals and vitamins. The goal of this study is to explore insect oils in terms of physicochemical properties to help their utilization in future against the possible scarcity of the resources in the world, and the most important point is to help to enable these valuable edible insect species as one of the main nutrient sour...
OPTIMIZATION OF HEMICELLULOSE COATING AS APPLIED TO APRICOT DRYING AND COMPARISON WITH CHITOSAN COATING AND SULFITE TREATMENT
Ubeyitogullari, Ali; Çekmecelioğlu, Deniz (2016-12-01)
Drying of hemicellulose-coated apricots was compared to sulfuring and chitosan coating. Air velocity, temperature and hemicellulose concentration were optimized using the Box-Behnken response surface methodology against total color change (Delta E-star), yellowness (Delta b(star)) and final moisture content. Drying kinetics were evaluated by Newton, Page and Logarithmic models. Diffusion coefficient, activation energy and rehydration rate were calculated. The optimal drying conditions were found as 1 m/s of...
EFFECTS OF SEMPERFRESH AND JONFRESH FRUIT COATINGS ON POSTSTORAGE QUALITY OF SATSUMA MANDARINS
BAYINDIRLI, L; Şümnü, Servet Gülüm; KAMADAN, K (Wiley, 1995-11-01)
Mandarins were coated with SemperSresh(TM) and Jonfresh(TM) edible coatings. The weight gain of mandarins after application of Jonfresh and Semperfresh coatings was 0.8% and 0.6% respectively. Weight loss, respiration rate, ascorbic acid, soluble solids (brix) and acidity changes of coated mandarins were compared with uncoated mandarins during storage at 20C and 40% RH for 4 weeks. Semperfresh(TM) and Jonfresh(TM) coatings delayed the ripening of mandarins. Both of the coatings were effective to reduce the ...
