Storage stability of whole and nibbed, conventional and high oleic peanuts (Arachis hypogeae L.)
MetadataDangos cofnod eitem llawn
Peanuts are increasingly being used as nibbed ingredients in cereal bars, confectionery and breakfast cereals. However, studies on their oxidative stability in this format are limited. Storage trials to determine the stability to oxidation were carried out on whole and nibbed kernels of conventional (CP) and high oleic (HOP) peanuts, with respect to temperature and modified atmosphere packaging. HOP exhibited the highest oxidative stability, with a lag phase in whole kernels of 12–15 weeks before significant oxidation occurred. HOP also showed higher levels of intrinsic antioxidants, a trolox equivalent antioxidant capacity (TEAC) of 70 mMol equivalence and radical scavenging percentage (RSP) of 99.8 % at the beginning of storage trials, whereas CP showed values of 40 mMol and 81.2 %, respectively. The intrinsic antioxidants at the beginning of these storage trials were shown to affect the peroxide value (PV), where RSP and TEAC decreased, and PV increased. Therefore, in peanuts the processing format (nibbed or whole) had the highest influence on susceptibility of lipid oxidation, highest to lowest importance: processing format > temperature > atmospheric conditions.

Laboratory re-enactment of storage practices of older adults to determine potential implications for growth of listeria monocytogenes Evans, Ellen W.; Redmond, Elizabeth (International Association for Food Protection, 2019)Older adults are more susceptible to listeriosis, and many frequently consume ready-to-eat (RTE) foods associated with Listeria monocytogenes. Consequently, safe storage of RTE-food is essential to reduce the risks of ...
