Effect of Filtration Methods of Various Types of Adsorbents on the Quality of Coconut Shell and Kusambi Liquid Smoke as Raw Materials for Processed Meat Smoking

Abstract

In this study, there were two groups, namely liquid smoke of kusambi and liquid smoke of coconut shells with various treatments of adsorbent filtration with 3 replications. There are three kind of treatment for each liquid smoke groups, first is liquid smoke without filtration process with adsorbent, liquid smoke with zeolite adsorbent treatment, liquid smoke with silica adsorbent treatment, and liquid smoke with activated charcoal adsorbent treatment. Analysis of variance showed that different types of liquid smoke and different adsorbent filtration had a very significant effect (P0.01) on antioxidants, total acid, specific gravity, tar, phenol content, pH, salinity, TDS, total yield, L* and b* color, hedonic color and smokey scent in the resulting liquid smoke. Analysis of variance showed that the different types of liquid smoke had no significant effect (P0.05), but the filtration treatment with different adsorbents had a very significant effect (P0.01) on viscosity. And the analysis of variance also showed that the different types of liquid smoke and the filtration of different adsorbents had no significant effect (P0.05) on the color a* of the resulting liquid smoke. The differences in the types of liquid smoke and the treatment of liquid smoke filtration with adsorbents had a very significant effect (P0 .01) on antioxidant, total acid, specific gravity, tar, phenol content, pH, salinity, TDS, total yield, L* and b* color, hedonic color, and smoke aroma in the liquid smoke produced. However, the different types of liquid smoke did not have a significant effect on the resulting viscosity (P0.05) and the different types of adsorbents in the liquid smoke filtration process had a very significant effect on the viscosity (P0.01). Meanwhile, the different types of liquid smoke and the different types of adsorbents in the liquid smoke filtration process did not have a significant effect on the value of the color a* or the reddish color of the liquid smoke (P0.05).
