Abstract

Coconut shell is an alternative type of raw material that can be used as a base for making liquid smoke because it contains cellulose, lignin, hemicellulose, and ash. Liquid smoke is a natural preservative that is obtained from the results of smoke condensate in the pyrolysis process of wood content containing hemicellulose, cellulose, and lignin. The use of liquid smoke is not only in the form of liquids because in the form of liquids, but phenol components and organic acids will also evaporate if stored for a long time so that it requires special containers and places for storing liquid smoke, so the development of microencapsulation technology is needed to cover phenolic compounds and starch acid using maltodextrin. Previous researchers stated that smoked flour had 70.79% phenolic compounds and 11.10% acetic acid, while the phenol compounds in liquid smoke were 24.03% and 57.70% acetic acid. The purpose of this study was to determine the acidity level of the meatballs with a liquid smoke microencapsulation system. The drying temperatures in the microencapsulation process were (ºC) 135, 140, 145, and 150 with a maltodextrin concentration of 30% and a particle size of 120 mesh. The results of the analysis of the acidity levels in meatballs increased at 145 ºC because there was an exponential bacterial growth phase, while at temperatures of 140 ºC and 145 ºC there was a stationary phase where bacterial growth was constant and at 150 ºC the acidity level decreased due to the increase in temperature. affect the speed of cell division so that acidity levels begin to decrease or be exhausted

Abstract

Liquid smoke can be obtained by condensing the smoke resulting from the pyrolysis chimney. Liquid smoke resulting from the pyrolysis process can be used as raw material preservatives, antioxidants, etc. Grade 3 liquid smoke is suitable for wood preservation and can also be used as a latex coagulant. In this study, it aims to determine what percentage of liquid smoke concentration is optimal for the preservation of meranti wood and determine the optimal soaking time of the meranti wood preservation process, the method used for the data retrieval process which is the measurement of acid content and the number of bacteria. The tool used is a series of pyrolysis tools. The acidity of meranti wood samples that are not soaked using liquid smoke is generally very high starting from 6±10, while for meranti wood samples soaked acidity levels are 5-6. The lowest bacterial mortality percentage (36.4%) control while the highest mortality percentage reaches 92%-100% indicated in the concentration of treatment. At a concentration of 25% able to inhibit bacterial attacks, it can be seen with a mortality percentage of 100% of all pyrolysis temperature levels. Liquid smoke retention at a concentration of 35% is the highest and more effective at immersion for 4 hours compared to the immersion of 3, 5, and 6 hours. Liquid smoke added to Meranti wood has toxic power to bacterial development. At a concentration of 35%, the average weight loss percentage of the test sample was 27.36%.
