摘要： The effects of ultrasound (US) pretreatment on natural structure modification from broccoli were investigated, and the influences of the modification on the bioaccessibility and cellular uptake efficiency of bioactive compounds were analyzed. US treated broccoli showed significant cell wall and cellular matrix degradation, which could be mainly responsible for the release of bioactive compounds from broccoli cells. Data from digested broccoli fractions showed that US pretreatment resulted in decrease of viscosity of the digesta, which could be partially responsible for the release of bioactive compounds from the digesta into the supernatant. High bioaccessibility of bioactive compounds appeared to be somewhat a similar high cellular uptake. The reduction of the particle size upon US pretreatment might be contributed to the increased carotenoid cellular uptake. These data indicated that US pretreatment may be considered as a potential processing method for improving the bioavailability of bioactive compounds.
