Potential application of pineapple waste as a fermentation substrate in yeast production

Abstract

Yeast global production showed that the demand for yeast products in many industries increases over the year. Therefore, there is a need to design a new process that is cheaper and can produce yeast in high volume to cater to the big demand. This plant design proposed the production of yeast using pineapple waste as feedstock. Several process routes using different types of substrates such as glucose, sugar cane and pineapple waste were discussed. Pineapple waste contains various minerals that can support the fermentation process for yeast production. This process includes the pretreatment of the feedstock which is liquid pineapple waste and undergoes thermal hydrolysis to convert sucrose to glucose. This is followed by the fermentation process and downstream process to obtain the yeast product. Several potential locations were also studied for the propose plant design by studying the advantages and disadvantages of each industrial area. By using this proposed plant design, it is expected that this yeast product can be produced locally by using available agriculture waste such as pineapple waste for potential yeast production.
