High‐pressure processing of persimmon purée: Stability during chilled storage
(Wiley, 2019-11-13)The aim of the study was to evaluate the effect of the high pressure (HP) technology on the preservation of persimmon purée during chilled storage (1, 30, and 90 days at 4 ± 1 °C). Results showed that the treatment at 400 ... -
Identification of the gamma irradiation dose applied to ground beef that reduces Shiga toxin producing Escherichia coli but has no impact on consumer acceptance
(Elsevier, 2020-11-18)The aims of the present study were: a) to estimate the minimal dose of gamma irradiation required to reduce 5 log CFU/g of native O157 and non-O157 Shiga toxin-producing Escherichia coli population in ground beef samples ... -
Impact of Adrenaline or Cortisol Injection on Meat Quality Development of Merino Hoggets
(2013-11)Increased levels of stress hormones in the muscle could lead to post mortem metabolic/structural modifications that could be reflected on meat quality. The present study investigated the metabolic effect of either adrenaline ... -
Impact of extracellular nucleic acids from lactic acid bacteria on qPCR and RT-qPCR results in dairy matrices : implications for defining molecular markers of cell integrity
(2017-07)In this study, we evaluated whether quantitative PCR (qPCR) and reverse transcription-qPCR (RT-qPCR) results could be affected by extracellular (free) DNA or RNA, respectively, obtained either from isolated bacteria or ... -
