Recovery Of Sugars From Blackstrap Molasses By Ion Exclusion., Edgar L. Aguirre G.
Recovery Of Sugars From Blackstrap Molasses By Ion Exclusion., Edgar L. Aguirre G.
LSU Historical Dissertations and Theses
Ion exclusion is a chromatographic separation of ionic from non-ionic material on a bed of ion exchange resins. This process has been proposed for the recovery of sucrose from molasses. However, separation of sucrose from the non-sugar and reducing sugar fractions is difficult. On the contrary, separation of reducing sugars from non-sugars is relatively easy. Inverting the sucrose to reducing sugars for further separation by ion exclusion gives a way to recover essentially all the sugars from molasses. Also, it eliminates the need for crystallization, since the reducing sugars can be sold in solution. The total sugar content in blackstrap …
Characterization And Bioavailability Of Alfalfa Leaf Protein Concentrate., Sirous Kashefi
Characterization And Bioavailability Of Alfalfa Leaf Protein Concentrate., Sirous Kashefi
LSU Historical Dissertations and Theses
Pressed alfalfa juice at pH 8.5 was heated (60(DEGREES)C) and centrifuged to produce a brown solution. This solution was further heated (80(DEGREES)C) at pH 4.0, centrifuged, and freeze-dried to produce a light tan powder. Tetrahymena pyriformis W. was used to test quality of cytoplasmic and chloroplastic fractions of alfalfa leaf protein concentrate (ALPC). Chloroplastic ALPC supported poor cell growth, probably because of high concentrations of chlorophyll, fat, and chlorogenic acid to which Tetrahymena is reported to be sensitive. Data indicated that isoleucine, phenylalanine, threonine and sulfur-containing amino acids in cytoplasmic ALPC were higher than those in soybean. Data indicated cytoplasmic …
Ultrastructural - Biochemical Changes And Sensory Correlations In Shrimp During Cold Storage., Teck Muk Wong
Ultrastructural - Biochemical Changes And Sensory Correlations In Shrimp During Cold Storage., Teck Muk Wong
LSU Historical Dissertations and Theses
Ultrastructural-biochemical changes and sensory correlations of penaeid shrimp during iced and frozen storage were analyzed. The aroma, color and acceptability of "wild" shrimp, P. setiferus from the Gulf of Mexico, were judged by six trained panelist to be superior to that of the pond-raised shrimp, P. stylirostris. However, P. stylirostris on the Master Mix Shrimp Diet has a slightly superior flavor than those fed with the Marine Ration 20 diet. Free amino acids, proline, glycine, taurine, and glutamic acid declined during the first 10 days of ice storage, and increased after 20 days. Leucine, and lysine increased linearly during ice …
Assessment Of Raw Milk Microbiological Quality By Adenosine-5'-Triphosphate Content And Preliminary Incubation Bacterial Count., Jeffrey J. Ryan
Assessment Of Raw Milk Microbiological Quality By Adenosine-5'-Triphosphate Content And Preliminary Incubation Bacterial Count., Jeffrey J. Ryan
LSU Historical Dissertations and Theses
Two hundred raw milk samples were collected and stored in sanitized plastic containers which were transported in ice to the laboratory. Three 100 ml sub-samples were aseptically removed from each container. One sub-sample (Fresh) was analyzed for Standard Plate Count (SPC) and adenosine-5'-triphosphate (ATP) content. The two remaining sub-samples underwent preliminary incubation; one sub-sample was incubated at 12.8(DEGREES)C for 18 h (PI 12.8) and the other at 7.2(DEGREES)C for 48 h (PI 7.2). Following incubation, SPC and ATP content were determined. Correlation of ATP content with SPC-Fresh, SPC-PI 12.8 and SPC-PI 7.2 was 0.72, 0.84 and 0.89 with log(,10) transformed …
