Cempedak (Artocarpus champeden) is a tropical fruit whose inner-skin contains high polyphenolic-based antioxidant. Traditionally, the inner-skin is soaked in brine to induce spontaneous lactic acid bacte-ria (LAB) fermentation. This research aimed to investigate the changes of polyphenolics substances and antioxidant activity during the course of spontaneous and Lactobacillus casei induced fermented at opti-mum (37°C) and sub-optimum (8°C) temperatures. Phenolic substances were spectrophotometrically measured with gallic acid (GAE), tannic acid (TAE), and catechin (CE) as the standards for the respective groups. The 50% maximum inhibitory concentration (IC50) for DPPH reduction was measured. A thin layer chromatography (TLC) using different solvents was utilized to qualitatively show differences of substances extracted from the unfermented and fermented mandai cempedak. The retention factor (Rf) values for TLC spots were measured after the plates were exposed under 366 and 254 nm of UV lamp. Fermentation increased phenolic substances release from the inner skin of cempedak which positively modulated the potential antioxidant activity. Sub-optimum temperature fermentation reduced total phenolic-based antioxidant. Ethyl acetate or combinations of n-hexane and ethyl acetate gave better separation in TLC plate. Differences in stain patterns were exhibited by mandai cempedak before and after L. casei induced fermentation. In summary, L. casei induced fermentation was more effective at optimum temperature to increase phytochemical substances of mandai cempedak, while spontaneous fermentation showed to be more effective after 11 and 13 days at sub-optimum temperature.

Kerupuk ikan gabus telah dikenal luas namun biasanya terbuat dari bagian dagingnya saja. Limbah berupa tulang ikan belum dimanfaatkan secara optimal, oleh karena itu dijadikan sebagai bahan substitusipada pembuatan produk kerupuk. Tujuan penelitian ini adalah untuk menentukan pengaruh substitusi tepung tulang ikan gabus (TTIG) sebagai fortifikan kalsium terhadap sifat sensoris dan fisika-kimia kerupuk ikan gabus. Penelitian ini menggunakan rancangan acak lengkap dengan perlakuan substitusi tepung tulang ikan gabus dalam tepung tapioka dengan kadar (0; 4; 8; 12; dan 16% b/b) dan di ulang sebanyak empat kali. Parameter yang dianalisis pada penelitian ini adalah sifat sensoris dan sifat fisika-kimia. Hasil penelitian menunjukkan bahwa substitusi TTIG berpengaruh nyata (p<0,05) terhadap sifat sensoris rasa, aroma, warna dan tekstur serta sifat fisika-kimia kerupuk ikan gabus. Peningkatan kadar TTIG menurunkan kadar air dan volume pengembangan kerupuk ikan gabus, tetapi meningkatkan kadar protein dan kadar kalsium (p<0,05). Substitusi TTIG sampai dengan 4% menghasilkan kerupuk ikan gabus dengan volume pengembangan yang sama dengan kontrol (tanpa substitusi TTIG) dengan kadar kalsium 200 mg/100 g dan kadar protein 14,27%. Rasa dan warna kerupuk ikan gabus disukai hingga substitusi TTIG 12%, sedangkan aroma dan tekstur disukai hingga substitusi TTIG 8%.

Snakehead fish (Channa striata), a freshwater fish, is known to havefunctional properties in helping the process of healing burns andwounds after surgery. Besides that, the use of seaweed as a source offood fiber is also widely reported. This research was conducted todesign fiber-rich fish nuggets. The purpose of this study was todetermine the maximum levels of seaweed substitution in theprocessing of snakehead fish nuggets based on sensory properties.Single-factor experiment (seaweed, Eucheuma cottonii, substitution)arranged in a Completely Randomized Design with four replicationswas applied in this study. The parameters observed were hedonic andhedonic quality sensory properties for the attributes of color, aroma,texture, and taste of nuggets. The data obtained were analyzed by theFriedman Test, followed by the Wilcoxon Rank Test to detect thedifferences between treatments. Treatment of up to 75% seaweedsubstitution (0, 25, 50, and 75%) decreases significantly (p 0.05) thehedonic sensory acceptance of the snakehead fish nuggets for allattributes except the texture which shows an increase. Whereas, thetreatment with substitution of seaweed in the narrow percentage of 0,5, 10, 15, and 20% gave an expected result, which showed that therewas no significant difference (p 0.05) of the hedonic sensoryresponse for the overall acceptance. Nevertheless, 15% of seaweedsubstitution provides the best hedonic sensory response for overallacceptance. These results indicate that 15% of seaweed (Eucheumacottonii) substitution is recommended for use in the processing ofsnakehead fish nuggets.
