How will the concentration of vitamin C in a fresh orange compare with the concentration in a carton of the same juice?

                                Studies have shown that freshly squeezed orange juice starts with higher vitamin C levels, but can lose up to 37.8% within 24 hours of refrigeration, while commercial carton juice is stabilized against such rapid decay. The way a fresh orange's vitamin C concentration compares with a carton of the same juice is a complex interplay of initial content, processing, and subsequent storage conditions.
