I don't know if fresh is always better. It is better at some things. I like freshly squeezed oranges at home but there have been several cases around the world where unpasteurised fresh orange juice has been the cause of salmonella infection.

Sometimes we trade taste and nutrition for convenience, safety, consistency and year round availability. I like freshly squeezed oranges off my orange tree but they don't grow all year round. I am mostly happy not to consume oranges out of season but that isn't really a basis for a sustainable industry and beverage companies have sensibly created a market for year round, consistent tasting juice products.
