Stabilitas Foto-Oksidasi Mayones Campuran Minyak Ikan Patin Dan Minyak Sawit Merah

---

The purpose of this study was to determine the effects of light on the
photo-oxidation stability of mayonnaise from a mixture of catfish and red palm
oil, which were seen in peroxide and TBA number, total carotene and tocopherol,
and sensory characteristics of the mayonnaise. The research was conducted
experimentally using a completely randomized design which consist of 3
treatments and 3 replications. The mayonnaise was made from a mixture of 20%
catfish oil and 80% red palm oil. The treatments performed were condition
storage, namely P1 (stored with aluminum foil packaging), P2 (stored without
aluminum foil packaging), and P3 (exposed to a light intensity of 7500 lux) for 2
days and evaluated every 8 hours. The results showed that the light increased the
peroxide and TBA number, but decreased the total carotene and tocopherol in the
mayonnaise. The highest increase of peroxide and TBA number was shown in P3
with k values of 0.0067 meq O2.kg-1.h-1 (R2 0.99) and 0.0061 mg
malonaldehide.kg-1.h-1 (R2 0.99), respectively. The highest decrease of the total
carotene was shown in P3 with a k value of 0.0155 mg.kg-1.h-1 (R2 0.99), but the
highest decrease of the total tocopherol was shown in P1 with a k value of 0.0161
mg.kg-1.h-1 (R2 0.98). The light also effected descriptively but did not hedonically
characteristics of color, aroma, texture and overall assessment of the mayonnaise.
The best treatment was P1 with descriptively characteristics of yellowish orange
color, red palm oil aroma, and thick texture. The hedonically characteristics of P1
were preferred on color and texture, but slightly preferred on aroma by the
panelist.
