Concentration of stable elements in food products

Description: Food samples were taken from commercial markets and analyzed for stable element content. The concentrations of most stable elements (Ag, Al, As, Au, Ba, Br, Ca, Ce, Cl, Co, Cr, Cs, Cu, Fe, Hf, I, K, La, Mg, Mn, Mo, Na, Rb, Sb, Sc, Se, Sr, Ta, Th, Ti, V, Zn, Zr) were determined using multiple-element neutron activation analysis, while the concentrations of other elements (Cd, Hg, Ni, Pb) were determined using atomic absorption. The relevance of the concentrations found are noted in relation to o… more

Energy use quantification in the canning of Clingstone peaches

Description: Thermal and electrical energy usages in a California Clingstone peach cannery were monitored to establish energy consumption levels and to identify energy intensive unit operations. Representative processing lines were instrumented with orifice plates for steam flow measurements and with electric watt transducers for electrical power monitoring to yield actual consumption values. Steam use in the lye peelers and retorts accounted for 98% of all energy consumed, indicating that further examinati… more

Technical and economic feasibility of utilizing apple pomace as a boiler feedstock

Description: Apple pomace or presscake, was evaluated for suitability as a boiler feedstock for Michigan firms processing apple juice. Based upon the physical and chemical characteristics of pomace, handling/direct combustion systems were selected to conform with operating parameters typical of the industry. Fresh pomace flow rates of 29,030 and 88,998 kg/day (64,000 and 194,000 lb/day) were considered as representative of small and large processors, respectively, and the material was assumed to be dried to… more

Design of data acquisition and control systems for environmental monitoring and microclimate control

Description: Modern fruit growing techniques rely heavily on automated control equipment to improve yields and reduce operating expenses. This thesis is part of a long term project whose ultimate goal is the automation and optimization of fruit production. This thesis describes the equipment that has been developed to date. Also presented is a brief methodology that considers how this equipment came to be. It should be noted that there are many related uses for climate control, most of which could make good… more

Non-destructive ripeness sensing by using proton NMR (Nuclear Magnetic Resonance)

Description: More than 80 kinds of fruits and vegetables are available in the United States. But only about 6 of them have their quality standards (Dull, 1986). In the 1990 Fresh Trends survey (Zind, 1990), consumers were asked to rate 16 characteristics important to their decision to purchase fresh produce. The four top ranking factors were ripeness/freshness, taste/flavor, appearance/condition and nutritional value. Of these surveyed, 96% rated ripeness/freshness as extremely important or very important. … more

New charcoal impregnants for trapping methyl iodide. Part II. Applications to a variety of base charcoals. [Tests on hexamethylenetetramine applied to carbons derived from cocoanut shells, coal, petroleum, and wood]

Description: Cooperative efforts have led to the development of several promising new impregnation formulations containing HMTA (hexamethylenetetramine) and iodine salts. The new formulations have been applied to base carbons derived from coconut shells, coal, petroleum, and wood. The newly developed impregnated carbons perform as well as, or better than, commerical charcoals containing triethylenediamine (TEDA). The most successful combinations consist of coal carbon impregnated to 2% HMTA, 2% iodine (as K… more

Concentrations of radionuclides and selected stable elements in fruits and vegetables

Description: Twenty-two types of fruits and vegetables collected from two commercial supermarkets have been analyzed for their radionuclidic and stable-element composition. A specific gamma-emitting isotope analysis was performed on each sample for /sup 40/K, /sup 60/Co, /sup 95/Zr-Nb, /sup 106/Ru, /sup 137/Cs, /sup 226/Ra, and /sup 232/Th. The concentration of the stable elements in each sample were determined using multi-element neutron-activation analysis (Al, Ag, Au, As, Ba, Br, Ca, Ce, Cl, Co, Cr, Cs, … more
