Prevention Of Hydrolytic And Oxidative Rancidity And Nutrient Losses In Rice Bran During Storage., Fatemeh Malekian Ramezanzadeh
LSU Historical Dissertations and Theses
Freshly milled raw rice bran was stabilized with microwave heat for 3 min. Half of raw and treated bran were packed in Ziplock(c) bags and the other half vacuum packed. Half of the samples were stored at 4--5°C and the other half at 25°C for 16 weeks. The free fatty acid (FFA) content increased rapidly in raw rice bran samples vacuum packed and samples packed in Ziplock(c) bags store at 25°C from an initial amount of 2.5% to 54.3% and 48.1%, respectively. FFA level increased significantly in raw samples vacuum packed and packed in Ziplock (c) bags stored 4--5°C from …

LSU Historical Dissertations and Theses
Raw milk samples (n = 246) and pasteurized milk samples (n = 104) were analyzed to determine adenosine triphosphate (ATP) and compared with the standard plate count (SPC). An ATP filtration method was used to filter milk samples prior to ATP determination, which was measured in relative light units (RLU). The ATP assay took approximately 7 minutes to complete and could allow rapid prediction of SPC which is a measure of raw milk quality. Linear regression analysis was performed on data from three raw milk treatments defined as; fresh milk samples, samples preliminarily incubated at 12.8 and 15.6$\sp\circ$C for 18 …
Granular Activated Carbon From Agricultural By-Products: Carbon Properties And Their Relationship To Sugar Decolorization Potential., Mohamed Ahmedna
Granular Activated Carbon From Agricultural By-Products: Carbon Properties And Their Relationship To Sugar Decolorization Potential., Mohamed Ahmedna
LSU Historical Dissertations and Theses
Representative samples of soft, low density, group 1 (rice straw, rice hulls, sugarcane bagasse) and hard, high density, group 2 agricultural by-products (pecan shells) were converted into granular activated carbons (GACs). Prior to pyrolysis, group 1 by-products were mixed with four binders, sugarcane molasses, sugar beet molasses, corn syrup and coal tar. GACs were produced from group 1 and 2 materials by physical activation (carbon dioxide, steam) or from group 2 materials by chemical activation (phosphoric acid). Carbons were evaluated for their physical (hardness, bulk density), chemical (ash, pH), surface (total surface area, pore size distribution, surface oxides) and adsorption …
