KADAR TANIN BIJI PINANG (ARECA CATECHU L) BERDASARKAN LAMA PEMANASAN DAN UKURAN SERBUK
Abstract: Areca nut plant
(Areca catechu L) had been used for adhesive medicine and tanner. Areca nut
plant contained many tannins in the seed. Tannin was a component of organic
substance which was very complex, consists of fenolic compound which was difficult
to be separated and cristalize, precipate the protein from solution and
compound with protein. This research purposed to know the influence of the
heating lenght and optimum dust size along with the interaction of two factors
above toward the level of tannin areca nut seed. This research was experiment
used extraction method with the heating length about 2 hours, 3 hours, and 4
hours along with the dust size about 60 mesh, 80 mesh, and 100 mesh. The
extract was tested to establish the highest level of active tannin. The result
of various analysis investigation showed that the factor of heating length and
dust size along with the interaction of two factors above were not influential
toward the level of active tannin. The
level of optimum active tannin attained on the heating length about 3 hours
with the dust size 80 mesh in the mount of 11,0022%.
