Pemanfaatan karaginan dalam pembuatan tepung puding instan dan pendugaan umur simpannya

Abstract

The aimed of this study was to use in the manufacture of flour karaginan instant pudding and perform shelf life estimation. This study was conducted in three stages as: (1) physico-chemical analysis caraagenan (2) the formulation and optimization of instant pudding powder formula and (3) estimation of the shelf life of instant pudding powder. The results showed the comparison of kappa and iota caraagenan to be formulated in the instant pudding powder with a ratio of 1:1 (the range of concentration 0.5 - 1.2% in both type of caraagenan). The composition optimum of the instant pudding powder based on the studied of formulation: caraagenan 4.72%; mocaf 5.14%, dextrin 88.58%, and KCl 1.57%. The verification formula of the instant pudding powder have been found that a gel strength 423.75 g and persent of syneresis 0.003. The sensory result of instant pudding powder was appearance 5.29, aroma 5.57 and texture 5.21. The gel strength of the commercial pudding have been found that a gel strength 400 g and persent of sineresis 0003. Shelf life of instant pudding powder is 8.0 months when stored at room temperature 27 °C.
