From the comparative analysis between freeze and spray dried beet root powder, better results were found for freeze-dried samples in terms of color, wettability and hygroscopicity. Freeze-dried samples required a longer amount of time to obtain into powder form as compared to spray dried samples. Whereas the solubility and water activity values were found slightly higher in spray dried samples as compared to freeze dried samples. The proximate analysis, such as crude fiber, crude fat, ash and carbohydrate values recorded better result for freeze dried samples as compared to spray dried samples. It can be concluded from this study that the beet root, when dried in the freeze drying process, has better results as compared to the spray drying process.","PeriodicalId":38505,"journal":{"name":"Bulletin of the Transilvania University of Brasov, Series II: Forestry, Wood Industry, Agricultural Food Engineering","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91144428","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}

Remote sensing analysis can be further enhanced when community perception regarding major drivers of change is integrated. The present study was an attempt to assess the land use land cover changes in the Ishkoman watershed in the Ghizer district. The study explored Landsat-5 and Landsat-8 images to assess the LULC dynamics from 1998 to 2018, and also used questionnaires for community perception regarding LULC changes in the past two decades. Supervised classification was used to monitor changes between 1998 and 2018 and the maximum likelihood technique was used to categorize the pixels into six classes: vegetation/forest area, bare rocks, water bodies, glaciers/snow area, rivers, water, and agriculture. Regarding the questionnaires, the correlation matrix and regression models were developed between independent variables (population, land type cleared, and extra land required for new family members) and dependent variables (land use dynamics factors and socio-economic variables). The results showed that all six land cover classes have shown temporal changes between 1998-2018 and the most significant change was observed in forests and pastures (which decreased from 18.7% to 5.9 %). Similarly, glaciers, water, rivers, and agriculture have changed from 13.1, 6.5, 9.3, 1.5 to 15.8, 4.0, 11.32, 3.1, respectively between 1998-2018. The largest change was observed in bare rocks which increased from 50.2 % to 60.06%. Moreover, temporal NDVI analysis showed a decrease in vegetation cover (conversion to bare rocks) between 1998-2018. The questionnaire results revealed that the highest correlation was shown between population increase and decrease in crop production (R2 = -0.348), whereas the lowest correlation was found in population increase and population access to bus stops (R2 = -0.167). Similarly, the highest correlation was found between access to roads and markets (R2 = 0.349) and dependent variable (land type cleared), whereas the lowest correlobserved in access to water resources (R2 = -0.021). The study concluded that land use land cover has been significantly changed from 1998 to 2018 in the Ishkoman Watershed. The study suggested more in-depth research to examine land use land cover changes at finer scales by using high resolution satellite imagery, and conducting details surveys regarding the underlying anthropogenic causes of land use dynamics.","PeriodicalId":38505,"journal":{"name":"Bulletin of the Transilvania University of Brasov, Series II: Forestry, Wood Industry, Agricultural Food Engineering","volume":"51 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76414246","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 aim of this study was the investigation of the effect of the thermosonication process on Kluyveromyces marxianus survival as well as the determination of the impact of this process on other quality parameters (viscosity and serum separation). For this reason, Kluyveromyces marxianus (about 105 cells per milliliter) inoculated into Doogh samples, thereafter samples being exposed to various thermosonication process conditions. Results showed that the thermosonication operation resulted in the reduction of the yeast population of Doogh samples (p <0.05). The lowest yeast population was observed in the sample subjected to acoustic density=1w/ml, T= 60°C and t=30min (1.7±0.01CFU/ml). Other operation conditions also had impact on yeast survival (p <0.05). Thermosonication also had significant effects on the viscosity of the Doogh samples. Serum separation of samples was also measured and observation implied changing serum separation magnitude between different samples in comparison with the control sample (p <0.05).","PeriodicalId":38505,"journal":{"name":"Bulletin of the Transilvania University of Brasov, Series II: Forestry, Wood Industry, Agricultural Food Engineering","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77682275","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}

Data was collected through household interviews and the total enumeration of all tree species on respondents’ landholdings. A total of 23 tree species were recorded integrated within the farming landscape as boundary plantings, scattered on crop fields, around the homestead and woodlots. There was a significant difference in the mean number of trees per household across the three wealth classes. Among the three wealth classes, the medium wealth category households have a relatively higher number of tree species than rich and poor households (p<0.05). Considering the ever-increasing population and the resulting demand for construction poles, fuelwood, household utensils, farm implements, and the fast-growing performance of the species, Eucalyptus camaldulensis Dehnh. was the first preferred tree species to households for planting. Tree integration in the farming landscape should be recognized since it will be invaluable in developing plans for agroforestry interventions. However, exotic tree species have dominated the status of indigenous tree species. Then, there should be a continuous and detailed extension system to upgrade the traditional management system and the tree selection to be integrated.","PeriodicalId":38505,"journal":{"name":"Bulletin of the Transilvania University of Brasov, Series II: Forestry, Wood Industry, Agricultural Food Engineering","volume":"74 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81275907","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}
