Pendugaan Umur Simpan Beras Rendang Yang Dikemas Dengan Kertas Minyak Dan Edible Film Tapioka Menggunakan Metode Akselerasi

ABSTRACT
Beras rendang is a traditional food from Payakumbuh, West Sumatra.
Beras rendang is made from white glutinous rice flour which is roasted until dried
and then mixed and cooked with liquid sugar and coconut milk. The purpose of
this study was to estimate the shelf life of beras rendang that is packed with oil
paper and tapioca edible film. Estimation of shelf life using acceleration method
was conducted by storing beras rendang for 30 days at three different
temperatures, i.e. 30°C, 35°C, and 40°C. The parameters observed during the
storage process were sensory assessments of rancidity and thiobarbituric acid
(TBA) values of beras rendang. Data were analyzed using linear regression and
the equations obtained were used to calculate the shelf life of beras rendang at
normal temperature, which is 27°C. Beras rendang stored using tapioca edible
film packaging had a longer shelf life compared to oil paper packaging. The beras
rendang shelf life packed with tapioca edible film based on rancidity sensory test
was 59.26 days on the zero order reaction with the regression equation of y = -
4542.9x + 11.545, an activation energy value (Ea) of 9,022.19 kal.mol-1, and the
value of quality degradation (k) was 0.027 quality unit per day. The beras
rendang shelf life based on the TBA value was 45.15 days on the zero order
reaction with the regression equation of y = -1991.7x – 2.3267, with an activation
energy value (Ea) of 3,955.51 kal.mol-1, and the value of quality degradation (k)
was 0.013 quality unit per day.
Keywords: Edible film, oil paper, shelf life, and beras rendang.
