Nutrition During Pregnancy, Lactation And Infancy, Minodokht Froozani

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

In many countries in South and East Asia, most diets are defective in quality, even when there is not a severe shortage of food. They do. not provide an adequate quantity of essential nutrients. One of the most severe deficiencies is in good quality protein. The solution to this problem is to produce and provide the right kinds of foods and to establish national food production policies which should make it possible to plan a better balanced diet based on sound nutritional principles and modern knowledge of nutritional requirements. Some degree of undernutrition, over-nutrition, or malnutrition occurs in most European …

The Effect Of Oven Temperature, Cooking Method, And Breed On The Tenderness, Juiciness, And Flavor Of Beef, Carma B. Stembridge

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effect of oven temperature, dry-roasting, and breed on the eating quality of beef was determined by sensory and objective methods. Two adjacent standing rib and two adjacent chuck roasts of prime, choice, and good grades from animals of Hereford, Shorthorn, and Charolais breeding were dry-roasted. Control roasts (9-12th ribs) were cooked at 325 F. Experimental roasts (6-8th rib and two chucks) were assigned an oven temperature of 325 or 250 F at random. All roasts were allowed to reach ah internal temperature of 155 F as recorded on a potentiometer.

Tenderness, as determined by a Warner-Bratzler shear, was greater …

Physio-Chemical And Toxicological Studies On Controlled Atmosphere Storage Of Certain Deciduous Fruits, Neil Adair Littlefield

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effects of controlled atmosphere on the metabolism of Golden Delicious and Rome Beauty apples, Anjou pears, and Lambert and Bing cherries were studied with respect to changes caused in the normal metabolic functions carried on during storage of these fruits. Atmospheres consisting of 1.5 per cent CO₂ and 2.5 per cent O₂ for the apples and pears and 10.5 per cent CO₂ and 2.5 per cent O₂ for the cherries were employed.

Fungi of the strains Botrytis alli, Rhizopus nigricans, and Penicillium expansum were subjected to controlled atmospheres at 21° C to determine …

Food And Nutritional Needs Of The World Population By 2000 A. D., Sitaram Shankar Kharbas

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Investigations were carried out to project the food needs of the world population by 2000 A. D., and to explore the possibilities of meeting these requirements.

About 70 percent of the world population presently living in developing countries do not get adequate diets, and suffer from many diseases of under-nutrition and malnutrition. They are unable to increase food production themselves. People in the developed nations have enough food and their food production is increasing at a rate faster than the rate of growth of population.

Cultivable land is the main source of food for man. The seas can also be …

Development And Evaluation Of A Waiver Examination For The Introductory Foods Course At Utah State University, Virginia Clark Bragg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A written objective-type waiver examination for the introductory foods course at Utah State University has been developed and evaluated.

Results of the study showed that the examination improved with revision. In addition, it was found that there was a statistically significant relationship between the score students achieved on the waiver examination and the total numerical score representing the final grade in the basic foods course.

There was apparently no significant relationship between the number of years experience students had in food preparation, the type of experience in food preparation, and their performance on the waiver examination. Apparently depth of knowledge …

5 Β- Pregnane- 3Α- 20Α- Diol Excretion In Urine Of University Women During The Menstrual Period, Rita Shin-Hui Liao

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Five normal healthy young university women while on self-chosen diets and living under normal conditions served as experimental subjects in this study. Urinary pregnanediol was measured for 10 days of the menstrual cycle. Meal frequency (3 meals vs. 2 meals with no breakfast) was also included in the study.

A modification of the method of Eberlein and Bongiovanni on thin layer chromatography was used to determine pregnanediol in the urine sample.

Urine pregnanediol excretion was in the pattern as investigated by other workers. The values rose in the latter half of the menstrual cycle, and fell prior to the onset …

Range Nutrition In An Arid Region, Lorin E. Harris

Faculty Honor Lectures

On the mountains, in the valleys, on the foothills and on the deserts of the Intermountain West grow millions of tons of vegetation. The chemical energy stored bv these plants is a potential source of useful energy for man. Some of the plant material has been used for fuel, other has been used as a source of lumber, chemicals, and paper, but the major part of this vast reservO'ir is useful to man because it is utilized by livestock. This native vegetation is grazed by livestock and they convert the plant energy to' high quality, desirable food energy for man.
