Abstract

AbstrakBekatul dari hasil samping penggilingan padi memiliki komponen gizi dan non-gizi. Proses fermentasi pada bekatul diketahui dapat meningkatkan komponen fenolik dan aktivitas antioksidannya. Penelitian ini menggunakan bekatul yang difermentasi dengan kapang Rhizopus oligosporus selama 72 jam dan diformulasikan sebanyak 15, 20, dan 25% ke dalam sereal sarapan jagung. Bekatul tanpa fermentasi juga dibuat sebagai pembanding. Karakteristik fungsional yang berupa aktivitas antioksidan, kadar total fenol, serat pangan, mutu fisik yang berupa derajat pengembangan (DP), indeks penyerapan air (IPA), kelarutan air (IKA), kekerasan dan kerenyahan, serta mutu sensori sereal sarapan dianalisis dengan menggunakan rancangan acak lengkap dua faktor dan diuji lanjut dengan Duncan Multiple Range Test. Hasil penelitian menunjukkan bahwa penambahan bekatul fermentasi mampu meningkatkan aktivitas antioksidan dan kadar total fenol, namun memberikan penerimaan sensori yang lebih rendah dibandingkan formula sereal sarapan yang lain. Kesimpulannya, substitusi dengan 25% bekatul tanpa fermentasi dalah yang paling disukai berdasarkan analisis warna, aroma, rasa, dan tekstur. Sereal sarapan dengan formulasi tersebut memberikan nilai DP, IPA, dan IKA yang spesifik dan memberikan tingkat kekerasan dan kerenyahan yang dapat diterima panelis, serta menunjukkan aktivitas antioksidan, kandungan total fenol dan serat pangan yang tergolong tinggi.Functional, Physical and Sensory Characteristics of Corn Breakfast Cereals Substituted by Fermented Rice BranAbstractRice bran as a by-product of rice mills contains a relatively high nutritious components, such as phenolic compounds. Fermentation process in rice bran may increase phenolic compounds and antioxidant activity. In this study, fermented rice bran using Rhizopus oligosporus for 72 hours were formulated into corn-based breakfast cereals at the concentration of 15, 20, and 20%. Non fermented rice brand was also used as a comparison. The functional characteristics that consisted of antioxidant activity, total phenol, and dietary fiber; physical quality, i.e. degree of expansion (DE), water absorption index (WAI), solubility index (SI), hardness and crispness; and sensory quality were analysed using a two-factor randomized experimental design followed by Duncan Multiple Range Test. As a result, fermented rice bran yielded less acceptable breakfast cereals than that of a non-fermented cereal, although the antioxidant activity and total phenol increased along the fermented rice brand. As a conclusion, substitusion with 25% non-fermented rice bran was the most accepatable in terms of color, aroma, taste and texture compared to other formulations. The formulated breakfast cereal had specified DE, WAI and SI, hardness and crispness, as well as showed high values of antioxidant activity, total phenol, and dietary fiber.

Abstract

Tujuan penelitian ini untuk mengkaji pengaruh intensitas cahaya terhadap stabilitas foto-oksidasi minyak ikan patin.  Minyak ikan patin murni sebanyak 30 ml disimpan dalam botol transparan bertutup selama 14 hari pada kondisi cahaya yang berbeda dan dilakukan penarikan setiap 2 hari.  Perlakuan adalah MIP1 (dibungkus alufo), MIP2 (tanpa dibungkus,), MIP3 (5.000 lux), MIP4 (10.000 lux), dan MIP5 (15.000 lux).  Perlakuan MP1 dan MP2 dilakukan dalam ruangan terbuka, sedangkan perlakuan MP3, MP4, dan MP5 dilakukan menggunakan kotak cahaya yang dapat dikontrol intensitas cahaya dan suhu.  Mutu minyak yang dievaluasi selama penyimpanan adalah bilangan peroksida, bilangan TBA, waktu induksi, dan penilaian sensori terhadap aroma.  Hasil penelitian menunjukkan bahwa paparan cahaya mempercepat kenaikan bilangan TBA, tetapi menurunkan waktu induksi dan penilaian sensori secara deksriptif dan hedonik terhadap aroma minyak.  Minyak yang disimpan dalam paparan intensitas cahaya 15.000 lux memperlihatkan peningkatan bilangan TBA tertinggi dengan nilai k 0,240 mg malonadehid/kg (r2=0,86) dan waktu induksi terendah selama 0,81 jam.  Aroma tengik terkuat dan tingkat kesukaan terendah terdapat pada minyak setelah disimpan selama 14 hari pada paparan intensitas cahaya 15.000 lux dengan skor 2,2 (tengik) dan 1,41 (sangat tidak suka).  Di sisi lain, bilangan peroksida kurang sensitif mengindikasikan stabilitas foto-oksidasi minyak ikan patin, dimana peningkatan bilangan peroksida tertinggi ditunjukkan pada paparan intensitas cahaya 10.000 lux dengan nilai k 0,192 meq O2/kg (r2=0,96).  The purpose of this research was to study the effect of light intensity on photo-oxidation stability of silver catfish oil.  A pure of 30 ml catfish oil was stored in sealed transparent bottles for 14 days under different light conditions and withdrawal every 2 days.  The treatments were MIP1 (wrapped with alufo), MIP2 (without wrapped), MIP3 (5,000 lux), MIP4 (10,000 lux), and MIP5 (15,000 lux).  The MP1 and MP2 treatments were conducted in an open space, while MP3, MP4, and MP5 treatments were carried out using a lightbox that can be controlled for light intensity and temperature.  The oil quality evaluated during storage was PV, TBA value, induction time, and sensory assessment of aroma.  The results showed that light exposure accelerated an increase of TBA value, but decreased induction time and sensory descriptively and hedonically for the aroma of the oil.  The oil which stored in light exposure of 15,000 lux showed the highest rate increase of TBA values with k value of, 0.240 mg malonaldehyde/kg (r2=0.86) and the lowest induction time of 0.81 hours.  The strongest rancid aroma and the lowest hedonic score were found in the oil which stored in the light exposure of 15,000 lux with a score of 2.2 (rancid) and 1.41 (strongly disliked).  On the other hand, PV was not sensitive to indicate the photo-oxidation stability of the oil, where the highest increase of the PV was shown in the light exposure of 10,000 lux with k value of 0.192 meq O2/kg (r2=0.96)
