example 1

[0053]Fresh mushrooms were obtained from Modern Mushroom Farm (Avondale, Pa.) and the Penn State MTDF. All mushrooms were protected from extraneous light exposure throughout the experiments.

[0054]A Steripulse®-XL 3000 (Xenon Corporation, Wilmington, Mass.) was used for Pulsed UV light exposure. A B-type lamp was used. The system generated 505 Joules per pulse. At 3.2 cm from the window or 9 cm from the lamp, the broadband energy was 0.873 J / cm2 per pulse. The system generates 3 pulses per second. All previous experiments were conducted using a Xenon C-type lamp.

[0055]Brown and white button mushrooms were sliced to expose gill tissue. They were randomly placed in 150 g lots into polystyrene containers. Oyster and Shiitake mushrooms were divided into 150 g lots and were arranged in the system so that there was a single layer of mushrooms. All samples were placed in the Pulsed UV system at a distance of 3.2 cm from the quartz window.

[0056]Brown and white button mushrooms were exposed f...

example 2

[0077]An experiment was conducted to determine if pulsed UV light treatment employed to enhance the Vitamin D2 levels could have any negative effects on other nutritionally valuable components like the unique antioxidant L-ergothioneine. Sliced white button mushrooms were exposed to 0, 20, 30, 40 and 50 seconds of pulsed UV light as described above. The results (FIG. 16) demonstrate that Vitamin D2 levels increased significantly with increasing time of exposure but L-ergothioneine levels were relatively unchanged. These data indicate that mushrooms can be enriched with Vitamin D2 using pulsed UV light and high ergothioneine levels are retained.

Abstract

An improved filamentous fungi is disclosed that has an enhanced nutritional profile by utilizing pulsed ultraviolet irradiation. According to the invention, the vitamin D component of mushrooms and other filamentous fungi may be drastically increased with no deleterious affects on appearance with the use of pulsed UV radiation. Mushrooms so treated had up to 1800% DV in one serving of fresh mushrooms.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority under 35 U.S.C. §119 of a provisional application Ser. No. 61 / 047,268 filed Apr. 23, 2008, which application is hereby incorporated by reference in its entirety.FIELD OF THE INVENTION[0002]This invention relates to a nutritional product for use in animal feed, foods and beverages and more particularly to a mushroom or fungi having an increased vitamin content.BACKGROUND OF THE INVENTION[0003]Mushrooms are valuable health food—low in calories, high in vegetable proteins, chitin, iron, zinc, fiber, essential amino acids, vitamins & minerals. Mushrooms also have a long history of use in traditional Chinese medicine. Their legendary effects on promoting good health and vitality and increasing a body's adaptive abilities have been supported by Western medicine as well. They are an excellent source of selenium, riboflavin, pantothenic acid, copper, niacin, potassium and phosphorous. Selenium is needed for the pr...
