Pesticide residues in liquid pekmez (grape molasses)

Environmental Monitoring and Assessment, 2007
In this study 32 pesticide residues and eight polybrominated diphenlyl ether (PBDE) congeners were measured in seven liquid samples from Kahramanmaraş, Turkey. A new method based on the best recovery was column extraction with n-hexane/acetone followed by gas chromatography electron-capture detection (GC-ECD), and mass spectrometry (GC-MS).

Modeling of the devolatilization kinetics during pyrolysis of grape residues

Bioresource Technology, 2012
Thermo-gravimetric analysis (TGA) was performed on grape seeds, skins, stalks, marc, vine-branches, grape seed oil and grape seeds depleted of their oil. The TGA data was modeled through Gaussian, logistic and Miura-Maki distributed activation energy models (DAEMs) and a simpler two-parameter model.

Pesticide Residue Management in Grapes

Indian Journal of Entomology
A laboratory experiment was conducted in completely randomized design (CRD) to evaluate the effectiveness of various decontamination methods in removing pesticide residues from grapes during 2022-2023. Organically grown grape plants at fruiting stage were selected from Cumbum, Theni district of Tamil Nadu and sprayed with a mixture of eleven pesticides

Pyrimethanil Residues on Table Grapes Italia after Field Treatment

Journal of Environmental Science and Health, Part B: Pesticides, Food Contaminants, and Agricultural Wastes, 2006
Residues of the pyrimidine fungicide pyrimethanil [N-(4,6-dimethylpyrimidin-2yl)aniline] were determined in table grapes "Italia" by gas chromatography nitrogen-phosphorus detector (GC-NPD). Pesticides were extracted from grapes with ethyl acetate and hexane solution (1:1 v/v), and were analyzed without any further clean up.

Pesticide residues in grapes and during vinification process

Food Control, 2010
Abstract Pesticide residues in vinification process of two white and two red grapevine varieties were monitored during the 2007 vintage. Crushed grapes, cake, must, lees and wine were sampled during the vinification process. Additionally, grapes were sampled during the ripening process.

Pyrolysis of maize, sunflower, grape and tobacco residues

Journal of Chemical Technology & Biotechnology, 1997
Pyrolysis of four agricultural residues (maize, sunflower, grape and tobacco) has been carried out in order to quantify their energy content. The main characteristics of the charcoals formed and the nature and quantity of gases produced have been determined. The process was studied batchwise by varying the reaction time (15–60 min) and temperature (400–

[Determination of diniconazole residue in grape by gas chromatography].

Se pu = Chinese journal of chromatography, 2003
An efficient method was developed for the determination of diniconazole in grape by gas chromatography. The diniconazole residue in the sample was extracted by acetone. The extract was cleaned-up by liquid-liquid extraction and then solid phase extraction. The diniconazole residue was separated completely from other impurities in the sample through SPB
