Abstrak

Penelitian ini bertujuan untuk mengekstrak getah pohon mete dan memodifikasi sifatnya untuk dapat digunakan sebagai senyawa pembantu proses pengeringan menggantikan fungsi getah Arab. Dengan menggunakan getah mete termodifikasi dari penelitian ini, permasalahan biaya pada proses pengeringan jus buah dengan spray dryer dapat diatasi. Getah pohon mete dipungut dan diendapkan dari larutan hasil penyadapan dengan bantuan etanol sebagai antisolvent. Dalam penelitian ini gliserin dan pati gandum digunakan sebagai bahan tambahan untuk memodifikasi sifat getah. Hasil penelitian menunjukkan bahwa getah pohon mete termodifikasi yang dihasilkan memiliki kualitas yang baik dan kesamaan sifat dengan getah Arab.
