Effect of heating temperature on volatiles of roasted laver.
NIPPON SUISAN GAKKAISHI, 1987 The effect of the heating temperature on volatile components of roasted lever Porphyra tenera were studied. Volatile components of dried lover and three roasted lavers heated at 140, 200, and 250°C were analyzed by gas chromatography and gas chromatography-mass spectrometry.

The Bitter Taste of Brazil's Temporary Import Ban on Robusta Coffee
Agribusiness, EarlyView.ABSTRACT Brazil, a leading Robusta coffee producer and exporter, faced a significant drought in 2016–2017, which drastically reduced production and depleted stocks. Consequently, Brazil temporarily permitted the import of one million 60‐kg bags of Robusta coffee in the spring 2017. An import ban was imposed shortly afterward due to lobbying by domestic
