Oil palm empty fruit bunches (OPEFB) can be used as raw material for Hydroxypropyl Methylcellulose (HPMC). HPMC can be used as a French fries coating to reduce oil uptake. This research aims to study the utilization of HPMC OPEFB as a French fries coating. This research consists of two stages. The first stage is cellulose extraction and HPMC synthesis. HPMC synthesis through alkalization, methylation, propylation, and neutralization. The second stage is the use of HPMC as a French fries coating with different concentrations (0, 1, 2, and 3%). Potatoes that have been peeled and washed, cut lengthwise with a thickness of about 0.5 cm. Further dipped in HPMC solution with different concentrations for 10 seconds, then carried out a frying pan. The HPMC from OPEFB is characterized by methyl and hydroxypropyl groups found at a wavenumber of 2891.30 cm-1, a ring of pyranose at 995.79 cm-1 and hydroxyls (OH) groups at 3371.10 cm-1. The coating of French fries with 3% HPMC OPEFB can reduce oil absorption by 16.09%. The higher the concentration of HPMC, will reduce the fat content but increase the moisture and the texture of French fries become softer. The preferred type of coating was HPMC 1%. Keywords: oil uptake, coating, french fries, HPMC, OPEFB. Practical Application: Oil palm empty fruit bunches (OPEFB) can be used as raw material for Hydroxypropyl Methylcellulose (HPMC). HPMC can be used as a french fries coating to reduce oil uptake. The coating of french fries with 3% HPMC OPEFB can reduce oil absorption by 16.09% and potential to be applied to the industry NONE Institutional Repository Institut Pertanian STIPER Yogyakarta cek245 My Library TURNITIN 20122 2023-04-02 08:12:46 2023-04-02 08:21:42 machine generated
