The Ascorbic Acid Content of School Lunches Served at the North Texas State Teachers College Demonstration School During March and April, 1944

Date: 1944
Creator: Bryan, Ada Ruth
Description: The purposes of the present study are to determine the ascorbic acid values of foods served in the lunch room of North Texas State Teachers College Demonstration School at the time food preparation is completed, at the beginning of the serving period, and at the end of the serving period; to ascertain the loss of ascorbic acid during these intervals; and to determine the quantity of ascorbic acid present in the size portions served primary, elementary, and high school students.

The Effect of Storage on the Ascorbic Acid Content of Four Varieties of Canned Fruit Juice

The Effect of Storage on the Ascorbic Acid Content of Four Varieties of Canned Fruit Juice

Date: 1943
Creator: Willard, Helen
Description: The purposes of this study are (1) to determine the ascorbic acid content of a variety of fruit juices available in Denton, Texas, during March to July, 1943; (2) to ascertain the loss of ascorbic acid when canned grapefruit, orange, pineapple, and apple juices are opened and stored in the home refrigerator for several days' use; and (3) by means of data obtained, to make recommendations as to the most advantageous ways of using one's "points" in purchasing canned fruit juices for their ascorbic acid value.

A Possible Role of Ascorbate in Boron Deficient Radish (Raphanus sativa L. cv. Cherry Belle)

A Possible Role of Ascorbate in Boron Deficient Radish (Raphanus sativa L. cv. Cherry Belle)

Date: August 2001
Creator: Sedlacek, Theresa D.
Description: The most apparent symptom of boron deficiency in higher plants is a cessation of growth. Deficiency causes a reduction in ascorbate concentration and the absorption of nutrient ions. Addition of ascorbate temporarily relieves deficiency symptoms. In boron sufficient plants the addition of ascorbate to media causes an increased uptake of nutrients. In an attempt to discover if ascorbate addition to deficient plants causes increased ion uptake, radish plants were grown hydroponically in four different strengths of boron solution. A colorimetric assay for phosphorus was performed both before and after supplementation. Results, however, were inconclusive.

The Vitamin C Content of Eight Varieties of Sweet Potatoes and the Effect of Cooking on the Vitamin Content

The Vitamin C Content of Eight Varieties of Sweet Potatoes and the Effect of Cooking on the Vitamin Content

Date: 1942
Creator: Eakle, Dorothy
Description: Since sweet potatoes, which also furnish vitamin A, are a common food in the popular diets of Texas and are so generally grown over the state, the purpose of this study is (1) to ascertain the amount of vitamin C in eight of the varieties most commonly grown and (2) to determine the effect of the three most popular methods of cooking (boiling, baking, and candying) on the vitamin C content of these varieties of sweet potatoes.
