Abstract: A nutritional supplement is provided containing two broccoli based components that are combined and, when ingested, react in the intestines to provide sulforaphane. Processes for producing the broccoli components of the nutritional supplement are also provided. The broccoli components are treated separately using supercritical fluid extraction to remove oils. The temperature and pressure of the supercritical extraction processes are controlled to provide broccoli components having the desired properties for the nutritional supplement.

Abstract: A spray dried myrosinase/ascorbate mixture is formed from the steps comprising: providing a source of myrosinase, adding ascorbate to the source of myrosinase, heating the source of myrosinase to a temperature of about 104° F. (about 40° C.) or higher, and spray drying the myrosinase/ascorbate mixture. The spray dried myrosinase/ascorbate mixture may be used to prepare isothiocyanates. The spray dried myrosinase/ascorbate mixture may also be mixed with glucoraphanin and used in an activated tablet or capsule.

Abstract: Cancer chemoprotective compositions containing reduced oil-content extraction meals made from plants containing natural oils and glucosinolates. The oil content of the extraction meals may be reduced using batchwise or continuous supercritical fluid extractions. Also provided are glucosinolate-rich compositions containing purified glucosinolates isolated from plant materials. The glucosinolate-rich compositions may be made by reducing the oil content of a plant materials containing natural oils and glucosinolates and isolating the glucosinolates from the reduced oil-content plant materials using a membrane extraction. Natural oils containing isothiocyanates are also provided. The natural oils are well-suited for use in skin and hair care products.
