Exsudação de ácidos orgânicos em rizosfera de plantas daninhas

Study of the shelf-life of a mixed araça (Psidium guineensis Sw.) and marolo (Annona crassiflora Mart.) jam

“…Damiani et al The organic acids were extracted according to Bazimarakenga, Simard and Leurox (1995), modified by Silva et al (2001), and were identified and quantified by HPLC (High Performance Liquid Chromatography) using a Shimadzu CLASS LC 10 chromatograph equipped with a SPD-M10A UV detector at a wavelength of 230 nm and a C-18 reverse phase column (150 × 4.6 mm). The sample injection volume was approximately 20 μL and water containing 0.1% phosphoric acid at a flow rate of 1 mL/minute was used as mobile phase.…”

Changes in the physicochemical and microbiological properties of frozen araça pulp during storage

“…Organic acids were extracted according to Bazimarakenga, Simard and Leurox (1995), modified by Silva et al (2001), and the identification and quantification of citric, malic, tartaric, and ascorbic acids were performed by HPLC (High Performance Liquid Chromatography) using a Shimadzu model CLASS LC 10 chromatograph, (Kyoto, Japan) equipped with SPD-M10A UV detector, at wavelength of 230 nm, using a C-18 reverse phase column (150 × 4.6 mm ID, 3 µm). The sample injection volume was adjusted to 20 μL using water containing 0.1% phosphoric acid as the mobile phase at flow rate of 1 mL.min -1 .…”
