ABSTRACT Banana bunch is a potentially large biomass and is only disposed of as waste. Banana bunch can be utilized in high-value-added products such as pectin. Pectin is an industrial material obtained by extraction from plant tissue and can be influenced by various factors, including temperature extraction. Temperature extraction is one factor that will determine pectin's properties and feat…
ABSTRACT Robusta coffee has higher caffeine than other types of commercial coffee. High levels of caffeine in robusta coffee can hurt health. One of the efforts to reduce this impact is by the decaffeination process. Decaffeination can be carried out enzymatically with the bromelain. Bromelain from pineapple peel can hydrolyze caffeine molecules that have a structure similar to proteins. The s…
