Abstract

The aim of this study was to determine the effect of pyrolysis temperature and pyrolysis time on thequality of liquid smoke of coconut midribs waste such as yield, pH, acetic acid, phenol. The method of thisresearch was the descriptive method. The variables of this study were pyrolysis time of 2 hours and 3hours and pyrolysis temperature of 200, 250, 300, 350, 400 oC with two repetitions. The result showedthat the best condition of coconut midrib liquid smoke was on the pyrolysis temperature of 400 oC, for 3hours pyrolysis time resulted in yield, pH, acetic acid and phenol of liquid smoke were 24%, 2.53, 6,45ppm, 3,76 ppm. The increase in pyrolysis time and temperature was also found to increase the yield,phenol, acetic acid, and pH. Keywords: Pyrolysis, liquid smoke, coconut midribs

Abstract

Arabica coffee’s grounds are the wastes from the production of coffee beverages and are known to contain several active compounds that can be used as an antioxidant. This research is therefore a follow-up work on the use of these coffee grounds nanoparticles as an active compound in gel production. This study focuses on the antioxidant effects of the gel product, using Box-Behnken Design with 3 factors(x) (carbopol 940, TEA, and coffee grounds nanoparticles) at 3 levels. Based on the results of this study, it is found that the high antioxidant effect with an average inhibition value was 43.485%.Furthermore, data analysis on the other hand showed a significant effect of linear Box-Behnken Design model on percentage inhibition with a p-value greater than 0.0001 and insignificant lack of fit validated by an F-value of 0.60, in addition to a p-value of 0.7621. The optimal solution of about 0.50% carbopol, 940 formulation, 0.40% TAE, and 2,313% nanoparticles produced 45,636% inhibition value with 0.812 desirability. Moreover, this arabica coffee grounds can be claimed as a new invention that has great potential in the health sector as an active compound for pharmaceutical preparations.Keywords: Inhibition, Nanogel, Coffee Grounds, Box-behnken

Abstract

The processing of mackerel tuna-based food products is still very limited, so efforts to diversify other mackerel tuna-based food products are needed. One of the products that can be made from fish meat is fishballs. Fishballs are a nutrient-rich product with a high-water content so that the product quickly became spoilage when stored at room temperatures. Liquid smoke is reported to have been used as a natural preservative. However, there are no reports regarding mackerel tuna fishballs that soaking in coconut shell liquid smoke could affect the consumer's preference on hendonic properties such as color, aroma, taste and texture. The product was analyzed using hedonic test is a test for color, aroma, taste, texture. The data was analyzed descriptively. The result shows that color preference of average 3.92 (likes), aroma preference of average 3.22 (likes), taste preference of average 3.81 (likes), and texture preference of average 3.26 (likes). Based on spoilage detection which shows spoilage characteristics such as off odor, off flavor, and acidity so that shelf life of mackerel tuna fishballs preserved with coconut shell liquid smoke predicted less than 5 days and more than three days at room temperatures. Keywords: Euthynnus Affinis, Organoleptic, Sensory-Based Detection, Food Diversification
