Abstract

The objectives of this research were both to know as well as to determine the exact concentration of lemongrass water extract applied during storage on the quality of tofu. A complete randomized experimental design with two factor of treatments was utilized. The first factor was concentration of lemongrass water extract with 3 levels of treatmens, i.e : T1 : 1 kg of lemongrass : 2 L of water, T2 : 1 kg of lemongrass : 3 L of water, T3 : 1 kg of lemongrass : 4 L of water. Whereas the second factor was the storage time, i.e : L0 : 0 day, L1 : 2 day and L3 : 4 day. Variables observed including chemical, and microbial. They consit of protein, moisture, TPC, and Salmonella. Results showed that lemongrass water extract with the concentration of 1 : 4 stored for 4 day had high protein and moisture, content which were 15.4%, and 74.37%, respectively results from microbial test showed that microbial growth was suspressed by the treatments and the content were still in the range set by Indonesian National Standard Agency.

Abstract

This research was aimed to determine the accurate ratio of concentration of tongka langit banana puree and water that would result in ice cream having good quality and would be preferred by consumers. A Completely Randomized experimental design having four levels of concentration ratio of tongka langit banana: water, i.e. 3%:52%, 5%:50%, 7%:48%, and 10%:45% was applied. Respective variables observed were chemical properties (protein, fat, vitamin C, and total solids contents), sensory properties (color, taste, texture, and overall acceptance), as well as physical properties (resistance / rate of melting). Results showed that the ratio of 7% : 48% was determined as the best ratio to produce ice cream with the best physicochemical and sensory properties.
