The loquat (Eriobotrya japonica Lindl.) is a fruit which has in its chemical constitution acids that act as antimicrobials. Among them, ursolic acid is studied while present in the fruit and as isolated triterpenic acid. ...
Natural antimicrobials combined with ultrasound treatments to enhance quality parameters and safety of unpasteurized strawberry juice
(Bellwether Publ Ltd, 2019-12)
The search for novel non-thermal preservation technologies is continuously growing, as traditional thermal processing may have undesirable effects on sensory and nutritional properties of fruit juices. Therefore, the aims ...
Volatile and odoriferous compounds changes during frozen concentrated orange juice processing
(2015-11-01)
Sixty-two volatile compounds were identified in orange juice from frozen concentrated orange juice (FCOJ) processing steps using HSSPME-GC-MS in combination with GC-OSME. Twenty-four compounds were perceived by OSME in the ...
Bioethanol production with different dosages of the commercial acrylamide polymer compared to a bioextract in clarifying sugarcane juice
(2017-10-01)
One of the most important steps is to clarify the juice, which are added synthetic polymer acrylamide base, aiming the fast settling of impurities present in the juice. However, this input is expensive and may have ...
Development of a new stir bar sorptive extraction coating and its application for the determination of six pesticides in sugarcane juice
(WILEY-BLACKWELL, 2011)
In this article, a novel polydimethylsiloxane/activated carbon (PDMS-ACB) material is proposed as a new polymeric phase for stir bar sorptive extraction (SBSE). The PDMS-ACB stir bar, assembled using a simple Teflon (R)/glass ...
Inactivation of Listeria monocytogenes and Salmonella Typhimurium in strawberry juice enriched with strawberry polyphenols
(John Wiley & Sons Ltd, 2021-01-30)
BACKGROUND: Low molecular-weight phenolic fractions (LMPFs) were extracted from Albion (LMPF-A) and Camarosa (LMPF-C) strawberry cultivars. Their antibacterial activity against Listeria monocytogenes and Salmonella Typhimurium ...
