Photo-oxidation using UV radiation as a sample preparation procedure for the determination of copper in fruit juices by flame atomic absorption spectrometry
(Brasil, 2012)
The present work proposes the photo-oxidation using UV radiation/H2O2 as an alternative procedure for pretreatment of industrialized fruit juice samples for determination of copper by flame atomic absorption spectrometry ...
Electroencephalographic assessment of pneumatically powered penetrating and non-penetrating captive-bolt stunning of bulls
(Elsevier B.V., 2019-05-01)
The electroencephalographic (EEG) responses of 31 bulls (zebu crossbred cattle) stunned with either pneumatically powered Jarvis penetrating (PCB) or non-penetrating captive bolt (NPCB) was examined. Animals were organized ...
Determination of soluble solid content in market tomatoes using near-infrared spectroscopy
(2021-08-01)
Tomatoes are widely consumed worldwide, and the soluble solid content (SSC) is one of the most important quality parameters for the commercialization of fresh tomatoes, mainly in the salad group. In this regard, partial ...
Miniaturization of optical sensors and their potential for high-throughput screening of foods
(Elsevier B.V., 2020-02-01)
Molecular fingerprinting technology has evolved from bulky laboratory benchtop instrumentation to field-deployable devices driven by advances in semiconductor and photonic technologies. The ongoing miniaturization of ...
Vibrational and electronic spectroscopic detection and quantification of carminic acid in candies
(Elsevier Ltd, 2019)
Carminic acid (CA) contained in one kind of gummy candy was detected and quantified by using vibrational and electronic spectroscopy, respectively; the proposed methodology in solution is simple and rapid without sample ...
Improvement Production of Hyaluronic Acid by Streptococcus zooepidemicus in Sugarcane Molasses
(2017-05-01)
Microbial hyaluronic acid (HA) production has been preferred rather than extraction from animal tissue for medical and cosmetic applications. In this context, to obtain an economically competitive HA production by Streptococcus ...
Nuclear Magnetic Resonance Spectroscopy in Analyses of Biological Samples
(SpringerCH, 2021)
Nuclear magnetic resonance (NMR) spectroscopy can be used for the analysis of almost all biological samples regardless of their complexity and physical state, sometimes requiring minimal sample preparation and handling ...
