Abstract

The present work aims to study the effect of anaerobic fermentation temperature on the production of ethanol fuel for three different types of sugar compositions in dates that commonly produced in Saudi Arabia. The fermentation temperature is considered as the most important factors affecting the production of ethanol. The obtained data referred that the ethanol yields from Sukkari dates were 107.6 cm³ L^–1 juice, 123.3 cm³ L^–1 juice, and 96.6 cm³ L^–1 juice, during anaerobic fermentation temperatures of 30°C, 35°C, and 40°C, respectively. Whilst, the ethanol yields from Khlass dates were 111.0 cm³ L^–1 juice, 122.0 cm³L^–1 juice, and 128.0 cm³ L^–1 juice during the same fermentation temperatures. Ultimately, the Berhi dates produced 121.0 cm³ L^–1 juice, 136.0 cm³L^–1 juice, and 136.0 cm³L^–1 juice, under the same fermentation temperatures. The obtained results showed that the production of ethanol would directly proportional to the ratio of glucose and fructose composition in dates.
