HIDROLISADO DE FÉCULA DE MANDIOCA COMO ADJUNTO DE MALTE NA FABRICAÇÃO DE CERVEJA: AVALIAÇÃO QUÍMICA E SENSORIAL
The brazilians breweries replace progressively starchy adjuncts by sugary liquid adjuncts made with maize. Thus, the objective of present work was saccharify cassava and maize and use them as malt adjunct on Pilsen beer production, in laboratory scale. The syrups (35 °Brix) were produced with cassava and maize starch by utilisation of Termamil and Fungamil commercial enzymes. The beers were made using malt and syrups in proportion of 2: 1, on extract basis. The wort was produced by infusion process, after cooling and clarification it was inoculated with lager yeast. The fermentation temperature was 10°C and the fermentative process was finished with 90% of attenuation. After that, the beers were bottled and lagered at 0°C by 14 days. The beers were chemically and sensorially analysed. The similarity of chemical composition of cassava and maize syrups reflected on the chemical composition of worts and beers. The chemical analysis showed there was not statistical difference between wort produced with cassava syrup and wort made with maize syrups. As well, the chemical analysis showed beers made with these adjuncts did not present statistical difference. The sensory analysis realised by triangular test, showed beer made with cassava syrup and beer produced with maize syrup were equal. It was concluded that cassava starch presents potential utilisation as raw material for brew maltose syrup production.
