Avaliação da Hidrólise Ácida e Alcalina do Caroço de Abacate para a Produção de Etanol

New patterns from replaceable sources have been searched by scientific community to ethanol produce. The seed of avocado has thereabout 20% of starch. The starch hydrolysis results fermentable sugars by Saccharomyces cerevisiae, and the ethanol is the major product of fermentation. The starch can be hydrolysed by acids, basis and enzymes. Previous studies showed that enzymatic hydrolysis can produce 26,01 liter of ethanol per ton of seed. At the present work, we analyzed the chemistry hydrolysis efficiency before the enzymatic hydrolysis and the use of dormant seed consequence. The Brix rate variation at each stage was evaluated and the ethanol concentration was determined with gas chromatograph technique. The chemistry hydrolysis with subsequent enzymatic hydrolysis was effective, producing until 61,8 L.ton-1. The use of dormant seeds wasn’t significative to raise the Brix rate. The seed of avocado demonstrated to be an alternative replaceable source to ethanol produce

Cromatografia Verde

Sustainability is the ability of human beings interact with the world, preserving the environment to not compromise the natural resources of future generations. This is the main goal of Green Chemistry, which is based on twelve basic principles. One of its branches, the Green Analytical Chemistry, apply these principles in their techniques, such as Green Chromatography. The aim of this study was to do a brief literature review on some chromatographic techniques (Gas Chromatography, High Performance Liquid Chromatography, High Temperature Liquid Chromatography, Ultra Pressure Liquid Chromatograph, Micro Liquid Chromatography and Super Critical Chromatography) and measure their impact on the environment
