Another issue to be considered is storage. Antioxidants and vitamin
E, in particular, can be easily destroyed by light, water and
heat (Wang, Xue, Newman, & Newman, 1993). Newly harvested
barley will often be in storage for between 4 and 18 months before
processing (Idaho Barley Commission, 2011). Even though barley is
usually stored in silos with cooling aeration systems at less than
15 C and ideally to 10 C (Viljoen, 2001); storage may have an
effect on vitamin E content and antioxidant capacity. Indeed, storage
at 25, 27 or 35 C led to a significant loss of vitamin E content
(Liu & Moreau, 2008; Wang et al., 1993). However, research has not
been published on the influence of storage on both antioxidant
capacity and vitamin E content in barley at the usual temperatures
used by industry
