Abstract

Liquid smoke has a strong and pungent distinctive aroma caused some contributors compounds in these products, among others, phenolic, carbonyl and acid. Adsorption using zeolites in this study aimed to reduce the levels of hard pungent aroma compounds contributors so that liquid smoke can be accepted by consumers. Various pH zeolite ie 2, 3, 4, 5 and 6 are used as adsorbent liquid smoke where the fraction of adsorption results sensory analyzed by 20 panelists selected. Liquid smoke fraction was selected based on the results of sensory testing further analyzed using GC-MS and then analyzes the data using analysis of variance (ANOVA) with SPSS software version 16, followed by Duncan range test level of 1%. The results showed that as many as 14 fractions were tested for sensory worth of 25 fractions of liquid smoke coconut shell results in zeolite adsorption pH 2-6 where 11 other factions have a scent that is "hard and pungent". Contributors to the volatile aroma compounds in the liquid smoke by GC-MS assay include phenolic groups, carbonyl and acid. Adsorption coconut shell liquid smoke using zeolite effectively reduced the smell "hard pungent" of the product. Necessary to evaluate the shelf life of liquid smoke zeolite adsorption results. Key Words :  Adsorption, aroma, coconut shell, liquid smoke, zeolite.

Abstract

Characterization of physical and chemical properties of aroma compounds from liquid smoke is a challenge because there is no satisfactory method of separation due to compound contributors generally present in a matrix at very low concentrations. This study aimed to separate and identify the components of "strong and pungent" liquid smoke aromatic compounds by adsorption using activated carbon method. The observed variables analyzed using GC-MS including yield, phenol, carbonyl, titration acidity and chemical compound profiles. The chemical components of liquid smoke found on the analysis by GC-MS were further analyzed using a molecular mechanics software to determine the polarizability, hydrophobicity and dwipol moment of each compound     in the liquid smoke fraction adsorption results. The analysis of variance (ANOVA) with SPSS software version 16, followed by Duncan Multiple Range Test at the level of 1% was employed especially for the yield of liquid smoke adsorption. The physico-chemical characteristics of  25 fractions of liquid smoke resulted from adsorption on activated carbon at pH 2-6 comprising of 0.53 to 3.89% phenolic; 1.09 to 2.59% carbonyl; 7.17 to 10.75% acidicity; and pH range from     2.39 to 2.91 with the color spectrum in the range of 308-415 nm. The results of the analysis using the molecular mechanics methods showed that the higher the value of polarizability and dipole moment of a compound, the more polar the compound. It is concluded that the removal of the "strong and pungent" aroma compounds on coconut shell liquid smoke in order to produce a mild scent (soft) can be performed by activated carbon adsorption method despite the results were not optimal yet. A polar adsorbent such as zeolite is requiredin the adsorption method for the removal of "strong and pungent” aroma compounds on liquid smoke

Abstract

The purpose of the research was to identify the physicochemical characteristics of acetatedarenga starch produced by way ofan acetylation technique. This study used a completely randomized design (CRD) with treatments consisted of five different time lengths of reaction between the arenga starch and acetic anhydride 5 % i.e. 15, 30, 45, 60 and 75 minutes.  The reaction between the arenga and the acetic anhydride 5% was being maintained at pH 8.0-8.5. The research resultsshowed that theacetatedarenga starch contained 6.69% of water, a viscosity of 376 cp and emulsion stability of 74.00%.  The viscosity of the acetated arenga starch produced is stable suggesting that this substance is suitable to be utilized in food processing. Key Word: Acetated arenga starch, Emulsion, Physicochemical and Viscosity.

Abstract

Liquid smoke has a strong and pungent distinctive aroma caused by some contributor compounds within the product including phenolic, carbonyl and acid. Adsorption using zeolites in this study aimed to reduce the levels of strong pungent aroma contributor compounds so that the liquid smoke can be accepted by consumers. Zeolite of various pH ie. 2, 3, 4, 5 and 6 were used as adsorbent liquid smoke. The fraction produced the adsorption was sensory analyzed by 20 panelists selected.  The liquid smoke fraction selected based on the results of sensory testing was further analyzed using GC-MS. Data was analyzed using analysis of variance (ANOVA) with SPSS software version 16, followed by Duncan range test at 1% level. The results showed that of 25 fractions of coconut shell liquid smoke generated by the zeolite adsorption at pH range of 2 – 6, 14 fractions were qualified for sensory tested while the remaining fractions had strong and pungent aroma. The contributor substances with strong and punge aroma in the liquid smoke found include phenol groups, carbonyl and acid. The adsorption of coconut shell liquid smoke using zeolite effectively reduce strong pungent aroma of the product. It is necessary to evaluate the shelf life of the liquid smoke adsorbed by zeolite.
