Light Backscatter Of Milk Products For Transition Sensing Using Optical Fibers, Frederick A. Payne, Czarena L. Crofcheck, Sue E. Nokes, Klat C. Kang

Biosystems and Agricultural Engineering Faculty Publications

Transition sensors are needed, particularly in the dairy industry, for detecting transitions in pipe flow systems from product-to-water or product-to-product (such as from chocolate to vanilla ice cream mix). Transition information is used to automatically sequence valves to minimize product waste. Optical fibers were used to measure light backscatter between 400 and 950 nm as a function of milk concentration in water and milkfat concentration in milk. The normalized response (100% for product and 0% for water) as a function of product concentration in water was approximately logarithmic for skim milk between 400 and 900 nm and approximately linear for …

Predicting The Cutting Time Of Cottage Cheese Using Backscatter Measurements, Czarena L. Crofcheck, Frederick A. Payne, Sue E. Nokes

Biosystems and Agricultural Engineering Faculty Publications

An automated system for monitoring culture growth and determining coagulum cutting time is needed for cottage cheese manufacturing. A light backscatter measurement system was designed and installed in a local cottage cheese manufacturing plant. A cutting time prediction algorithm was developed using parameters generated from the backscatter profile. The cutting time prediction algorithm, T_cut = T_max + β₂ S, used two time-based parameters generated from the backscatter profile (T_max and S) and one operator selected parameter, β₂, to predict the coagulum cutting time, Tcut. The standard error of prediction for the algorithm was 6.4 …

Modifications Of Phosphocaseinate Solutions Treated By Selective Adsorption, Nathalie Martin, Rafael Jiménez-Flores, Phillip S. Tong, Yves Pouliot, Michel Britten

Dairy Science

The treatment of phosphocaseinate by adsorption with diatomaceous earths has been studied. The results suggest that magnesium and calcium silicates have a specific affinity for milk proteins. As a result, the ratio of individual casein types in phosphocaseinate solution can be manipulated.

Food Choices For The 21st Century, Louise Berner, Nancy Childs, Constance Geiger, Carl Keen, Janet King, Janet Mcdonald, Sanford Miller, Suzanne Murphy, Harold Schmitz, Anne Shaw, Phil Tong, Connie Weaver

Dairy Science

In December 1997, a coalition of health professional with a wide range of expertise in science, government, education, marketing and communications, convened to discuss the challenges and implications of food choices for the 21st Century. Taking the newly published Dietary Reference Intakes (DRIs) as a framework and starting point, the members of the coalition explored how health professionals can individualize dietary recommendation to help guide people in their food choices.

Profit From Pastures, Mark Callow, Martin Van Houtert

Journal of the Department of Agriculture, Western Australia, Series 4

The research program has made a major contribution to the improvement of pasture management techniques, which has, in turn, led to a gain in productivity for dairy farms in the south-west of Western Australia. Analysis has shown a 25 per cent improvement in pasture utilisation, an increase in the average number of cows milked from 155 to 192, an increase in average stocking rates from 0.9 to 1.2 cows per hectare, and increased income from milk sales by $600 per hectare. There are still areas for improvement in sustainability, productivity, and profitability, but the success to date is a credit …

Whey Protein Edible Film Structures Determined By Atomic Force Microscope, L.E. Lent, L. S. Vanasupa, P. S. Tong

Dairy Science

Atomic force microscopy was used to study edible films produced from whey proteins. The films were imaged under ambient conditions with no special sample preparation. Low resolution imaging of areas from 10 μm to 150 μm on a side was performed in the contact mode. Higher resolution scans of 350 nm to 2,700 nm required use of the noncontact imaging mode. Features about the same size as the primary protein in whey, beta-lactoglobulin (7 nm), were identified in the film samples. Molecular aggregates in the range of 1 μm, reported in other studies using transmission electron microscopy of whey protein …

Diffuse Reflectance Changes During The Culture Of Cottage Cheese, Frederick Alan Payne, R. Carol Freels, Sue E. Nokes, Richard S. Gates

Biosystems and Agricultural Engineering Faculty Publications

A sensor for measuring diffuse reflectance of milk during the typical 6-h culture of cottage cheese was installed in a local manufacturing facility. Diffuse reflectance was found to increase slowly during the first three hours of the culture and increase rapidly toward the end of fermentation. The correlation between parameters generated from the diffuse reflectance profile and cutting time was sufficient to develop an algorithm for cutting time prediction. An algorithm incorporating t_max (time from adding culture to the maximum rate of change in reflectance) and slope of the reflectance curve at t_max predicted the operator selected cutting …

The Influence Of Connective Tissue In Meat Tenderness (A Histological And Comparative Study), Rachael Anne Adams

Undergraduate Honors Capstone Projects

There are several means of determining the tenderness of meat. Recently, a great deal of effort has been focused on connective tissue, or collagen, as a measure of tenderness. These foci have included biochemical determination of collagen types, the ratios of soluble and insoluble collagen, changes of collagen with age, and abundance of collagen.

The purpose of this study is to evaluate the abundance of collage as a means of differentiating levels of tenderness , using histology. Steaks taken from the bovine tenderloin, inside round, and bottom round (eye) were observed histologically using special stains for connective tissue. This method, …

The Role Of Ammonia In Reproductive Inefficiency In High-Producing Dairy Cows Fed Excess Rumen Degraded Protein, Douglas Scott Hammon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The role of ammonia in reproductive inefficiency in early lactation dairy cows was studied in a series of experiments designed to determine the concentrations of ammonia in normal bovine follicular fluid (bFF), to determine the effects of ammonia on the bovine embryo during specific stages of development, and to test the hypothesis that elevated plasma urea nitrogen concentration is associated with elevated ammonia and urea nitrogen concentrations in the reproductive fluids.

In the first study, ammonia concentration in different size follicles and the effect of ammonia during in vitro maturation on embryo development were determined. Ammonia concentration in the bFF …

Selecting Linear-Score Distributions For Modeling Milk-Culture Results, H. G. Allore, David J. Wilson, H. N. Erb, P. A. Oltenacu

Animal, Dairy, and Veterinary Science Faculty Publications

The data for this cross-sectional retrospective study are from surveys of 65 dairy-cattle herds in central New York, USA sampled between February, 1993 and March, 1995. The objective was to identify probability distributions of logarithmically transformed somatic-cell counts (linear score) for use in a simulation model of mastitis and milk quality. Probability density functions were estimated using maximum-likelihood estimators for the linear score of individual-cow composite milk samples culture negative and culture positive for the pathogens Streptococcus agalactiae, Streptococcus non-agalactiae, Staphylococcus aureus, and coagulase-negative staphylococci for the complete dataset and by bulk-tank somatic-cell count group (< 500 000, ≥ 500 000 SCC/ml). Based on the rankings of three goodness-of-fit tests (Anderson-Darling, Kolmogorov-Smirnov and x^{2 …}
