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.

Claims

1. A process for producing a broccoli supplement containing active myrosinase enzyme comprising the steps of:

(a) providing a first and second broccoli product comprising broccoli seeds or sprouts;

(b) preparing the first and second broccoli products for treatment to remove oils contained in the broccoli products;

(c) treating the first prepared broccoli product using supercritical fluid extraction with carbon dioxide at a temperature of about 185°

F. or greater and a pressure of up to about 600 bar;

(d) treating the second prepared broccoli product using supercritical fluid extraction with carbon dioxide at a temperature of between about 140°

F. to about 175°

F. to remove oils contained in the broccoli product and to deactivate ESP contained in the broccoli product, wherein the resulting broccoli product comprises active myrosinase enzyme; and

(e) combining the first and second treated broccoli products.

2. The process of claim 1, wherein the first and second broccoli products are broccoli seeds.

3. The process of claim 1, wherein the first and second broccoli products are prepared for treatment by one of grinding, chopping, milling or rolling.

4. The process of claim 2, wherein the first and second quantities of broccoli seeds are prepared for treatment by rolling and flaking to produce a broccoli seed meal.

5. The process of claim 1, wherein the second prepared broccoli product is treated using supercritical carbon dioxide at a pressure of between about 275 to about 325 bar and at a temperature of between about 140°

F. to 175°

F.

6. The process of claim 4, wherein the second prepared broccoli seeds are treated using supercritical carbon dioxide at a pressure of about 300 bar and at a temperature of about 145°

F.

7. A nutritional supplement comprising:

(a) a first deoiled broccoli seed meal, wherein the broccoli seed meal comprises less than 2% by weight oil and wherein substantially all of the myrosinase and ESP in the broccoli seed meal is deactivated;

(b) a second deoiled broccoli seed meal containing active myrosinase and deactivated ESP;

(c) an ascorbate and

(d) an acid resistant capsule.
