The acid casein hydrolysate was added at different levels (0, 10, 20, 30, 40 and 50%) into process cheese spread blends made from young Cheddar cheese (15 days storage) just before processing. The chemical composition, radical scavenging activity, total free amino groups and sensory properties of the products were evaluated. The results showed that the radical scavenging activity of the resultant cheese increased with increasing the concentration of casein hydrolysate. Also, free amino groups were estimated in process cheese while fresh and during storage )20,40 and 60 days) at 7°C ± 1°C, the results were represented as the increase in optical densities (O. D). The obtained O. D. values increase with increase the concentration of casein hydrolysate. The O.D values increased to 0.976, 0.986, 1.023, 1.137, 1.164 and 1.203 after 60-day storage in the same order. Moreover, cheese preparations underwent sensory evaluation for appearance, aroma, taste, mouth feel, color, overall quality and total score. In general, no significant differences (P <0.05) were observed between control sample and treated samples with 10, 20 and 30% casein hydrolysate for total scores therefor, these samples can be grouped together. However, the cheese made with 40 and 50% casein hydrolysate received significantly (P < 0.05) lower scores and water phase separation was observed after 60 days storage with 50% treatment.","PeriodicalId":18575,"journal":{"name":"Minia Journal of Agricultural Research and Development","volume":"57 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87603995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results of this study indicated that there were no significant changes in water suitability criteria for irrigation with magnetized water from unmagnetized significantly were observed by magnetic field treatment. However, irrigation with magnetized water increased water and fertilizer use efficiency and productivity and consequently increased peach crop yield over irrigation with unmagnetized water. Results of this significantly study showed that when sandy soil were irrigated with magnetized water, soil moisture content in root zone increased from 9.45% for control treatment to 12.03 % in the first 200 m irrigation distance from the magnetic field device. Moisture content in root zone was significantly decreased as the irrigation distances increased from 200 to 400 and 600 m distances. This indicates that the effect of magnetizing irrigation water decreases with increasing the irrigation distance from the magnetic device at the head of the field. It could be concluded that, using magnetic technology for groundwater treatment in arid regions would increase the possibility of using saline water for safe irrigation on the long-run.","PeriodicalId":18575,"journal":{"name":"Minia Journal of Agricultural Research and Development","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88645827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The obtained results confirmed that spraying Manfalouty pomegranate trees with chitosan at 50 ppm to 400 ppm significantly improved pomegranate fruits physical and chemical properties as well as yield (kg)/tree, fruit number/tree and fruit weight (g). This promotion was parallel with increasing chitosan concentration. However, non-significant differences were observed between the two highest concentrations used (200 and 400 ppm), during the two experimental seasons. INTRODUCTION The Pomegranate tree (Punica granatum L.) belongs to Myrtales order and Punicaceae family.. Pomegranate is an ancient beloved plant and fruit. The name ‘‘pomegranate’’ follows the Latin name of the fruit Malum granatum, which means ‘‘grainy apple.’’ The generic name Punica refers to Phoenicia (Carthage) as a result of mistaken assumption regarding its origin (Shulman et al., 1984; Morton, 1986; Holland et al., 2009, and Ampem, 2017). The pomegranate has gained high economic value in recent years due to the large volume of in vivo and in vitro studies attributing numerous health benefits to the fruit and its products (extensively reviewed in Holland et al., 2001; Fadavi et al., 2005; Holland et al., 2009; Fakhour 2012 and Franck et al., 2012). Over the past three decades, there has been a growing interest in developing natural alternatives to Ibrahim et al., 2020 100 synthetic polymers, namely, biopolymers. Chitosan is produced by deacetylation of chitin, which is the structural element in the exoskeleton of crustaceans, such as crabs and shrimp, and cell walls of fungi. Chitin is the second most prominent biopolymer after cellulose found in nature (Rinaudo, 2006 and Kim & Kim2011), due to their remarkable macromolecular structure, physical and chemical properties, and bioactivities, chitosan have received much attention in fundamental science, applied research, and industrial biotechnology (Dima et al., 2017; Philibert et al., 2017). This investigation aimed to study the effect of spraying chitosan (at 50. 100, 200, and 400 ppm) and frequencies of applications (once, twice and thrice) on yield and its components as well as fruit quality of Manfalouty pomegranate grown under Assiut Governorate conditions. MATERIALS AND METHODS The field work of this investigation was conducted during two successive seasons (2018 and 2019) at private orchard located at ElQusiya district, Assiut GovernorateEgypt, where the soil texture is heavy clay and water table depth is not less than two meters, surface irrigation system was used.
