| Summary: | This paper is concerned with the ability of natural products such
as vinegar, tea, okra, lemon juice, grapefruit peel essential oil,
and baking soda to prevent mold growth on bamboo and wood
materials. The results showed that grapefruit peel essential oil
had the highest biological activity compared to the other products
in preventing mold growth on wood materials. Additionally, a
process for preventing mold growth on bamboo and wood
materials was developed and the parameters were optimized
using the Box-Behnken surface response correlation method. The
optimal process conditions were determined by analyzing the
response surface of the three-dimensional surface plot and
solving the regression model equation using Design Expert
software. The optimal conditions, including the ratio of product
to coverage area 5/1, concentration 53%, time in 238 minutes and
temperature 40𝑜𝐶, have been tested and showed that the time for
mold appearance was 254 days.
