Isothiocyanates (ITCs) are well-known chemopreventive agents that have received significant interest across the nutrition and pharmaceutical industries owing to their anticancer properties, thus it is essential to increase the conversion of glucosinolate to ITCs by myrosinase to maximize their health benefits. In this paper, using broccoli seed meals as a raw material, we comparatively analyzed the outcomes of two extraction methods: (i) hydrolysis followed by extraction (HFE) and (ii) simultaneous hydrolysis and extraction (SHE) in terms of the ITC yield. The results revealed that the SHE method showed a relatively greater erucin production from broccoli seeds and greater antitumor and antioxidant activities. A similar phenomenon was found for the hydrolysates of crude myrosinase and crude glucosinolate separated from broccoli seeds. However, when the crude glucosinolates were hydrolyzed by purified broccoli myrosinase, or when pure glucoraphanin was hydrolyzed by crude myrosinase, no significant effects were noted on the types and yields of ITCs between the SHE and HFE methods.
