The lectures on YouTube were evening lectures meant to summarize each week of class, but the actual in-person students learned more about the actual chemistry involved, and did guided experiments to test different properties of food. I was hoping the EdX course by the same professors would give me an approximation that experience, but I was really disappointed. Technically there's a lot of good information still there, but the main problems were that the lectures were split into 2-minute chunks and the EdX UI constantly gets in the way of actually absorbing the content. I decided to buy a couple books on the topic instead.

To learn something, you need to watch a lecture, then receive a task, perform the task and provide a result, then receive feedback, and, finally, learn from the feedback.

Harvard video lectures are just another form of TV. They are mostly useless without Harvard.
