Abstract

Aflatoxin, produced by Aspergillus flavus and Aspergillus paraciticus, commonly contaminates agricultural and processed products. This study aims to analyze aflatoxin levels in fried onions produced in Palu through high-performance liquid chromatography (HPLC) using an immunoaffinity column an a  fluorescent detector at an excitation wavelength of 360 nm and an emission wavelength of 440 nm. The standard working chromatogram of aflatoxin gave a peak response at retention times of 28.618 minutes for aflatoxin B1, 21.985 minutes for aflatoxin B2, 17.625 minutes for aflatoxinn G1, and 13.719 minutes for aflatoxin G2. The limit of detection (LOD) values for each standard were : aflatoxin B1 : 0.2607 ng/ml; aflatoxin B2 : 0.0600 ng/ml; aflatoxin G1 : 0.1986 ng/ml; and aflatoxin G2 : 0.0310 ng/ml.  The chromatogram results of the 10 fried onion samples analyzed showed no peak response with the same retention time as the standard aflatoxin retention time, so that the 10 samples can be concluded as meet requirements.

Abstract

Vannamei (Litopenaeus vannamei) Peeled Deveined Tail-On (PDTO) shrimp is frozen shrimp product consumers highly preferred. However, shrimp products are easily perishable that require a proper cold chain system to preserve their quality, shelf life, and nutritional value. This study investigated the cold chain implementation of PDTO shrimp processing in the fishery industry. The temperature of shrimp products, water, and rooms was monitored during processing. Results showed that the shrimp temperature measured in each process was below 5°C. However, abusive temperatures were detected in water used in the peeling and deveining step and soaking process, while water and shrimp temperatures altered each other. Moreover, room temperatures were recorded under 20°C, conforming to Ministry of Marine and Fisheries regulations. Air Blast Freezer and cold storage temperatures revealed that ABF and CS could not meet the company’s temperature standards. These findings may help shrimp companies monitor steps indicating to have temperature abuse attentively.

Abstract

Pumpkin flour produced through fermentation can increase its nutritional value. This study aims to analyze the chemical characteristics and antioxidants of fermented pumpkin flour with variations in microorganisms and fermentation time, as well as the correlation between the two factors, and determine the best formulation. This study used a factorial group randomized design method with two factors, namely, variation of microorganism and fermentation time. The data obtained were analyzed using factorial ANOVA, followed by the Duncan Multiple Range Test (DMRT) test with a confidence level of 95% using SPSS 23. The chemical characteristics of fermented pumpkin flour showed an interaction between fermentation microorganisms and the length of fermentation time on the antioxidant activity of fermented pumpkin flour, but there was no interaction between fermentation microorganisms and the length of fermentation time on the moisture content, ash, protein, fat, and carbohydrates of fermented pumpkin flour. Fermentation by S. cerevisiae for 3 days had the best chemical characteristics and antioxidant activity of fermented pumpkin flour. Researchers hope that the application of fermentation in processing pumpkin into flour can increase the nutritional value, the economic value, and the value of health.

Abstract

Coffee is processed with a variety of processes such as natural (dry), fullywash (wet), and honey processes. The type of coffee processing influences the characteristics of the coffee produced. The aim of this research is to analyze the physicochemical characteristics of the Sigarar Utang variety of arabica coffee based on different processing methods (fullywash, honey and natural process). The research design used a one-factor Completely Randomized Design (CRD). The research results showed that the type of coffee processing method had a significant effect on water content, coffee essence content, sucrose content, total dissolved solids (TDS), total titratable acidity (TTA), pH, total phenols and antioxidant activity of coffee brewing, but had no significant effect on ash content. The test results for water content, ash content and coffee essence content are in accordance with the Indonesian National Standard (SNI) for coffee powder. Coffee with honey processing has high values ​​for water content, sucrose content, and TDS, while coffee with fullywash processing has the highest acidity, total phenols and antioxidant activity.

Abstract

Wine coffee is fermented coffee cherries with a wine-like flavor and aroma. The purpose of this study was to isolate, characterize ethanol-tolerant and thermotolerant yeast from Semeru Arabica wine coffee cherries and to determine the molecular identification of the selected yeast. In this study, the Semeru Arabica coffee cherries were fermented for 30 days.Yeast isolation was performed on samples collected each week during fermentation. The selected isolates were characterized for macroscopic and microscopic morphology, followed by ethanol and temperature tolerance analysis. The isolate with the most desirable characteristics, designated CW30, grew well at 30ºC but was sensitive to temperatures above 35ºC. The isolate grew well in media containing 5% ethanol but was sensitive to a 10% ethanol concentration. Based on nucleotide sequence analysis, CW30 exhibited 100% similarity with Candida ethanolica isolate 3-1-19.

Abstract

This study was conducted to identify the best fermentation period and roasting temperature for semeru arabica wine coffee. This study used the factorial RSBD research approach (three levels of roasting temperature and four levels of fermentation duration). Physicochemical and organoleptic data were analyzed using ANOVA 5%, LSD 5%, and HSD 5%. Then, the best treatment's ash alkalinity, coffee juice content, and caffeine level were assessed. According to the study, the fermentation period has impact on the moisture level of green beans, the moisture and ash content of roasted beans, acidity, body, and balance. The water and ash content of roasted beans, aroma, flavor, acidity, aftertaste, body, balance, and overall attribute, are influenced by the roasting temperature. Then the interaction between factors significantly affects the water content of roasted beans, flavor, acidity, and body. The best treatment achieved a total score of 81.83 (40 days, 200 °C).

Abstract

The current trend in coffee product diversification is wine coffee, which has a wine-like flavor and aroma. Reviews of wine coffee are still limited, especially those related to microbial succession during the fermentation process. The objective of this research was analyzing the microbial population and the effect of microbial succession during fermentation process of Arabica Semeru coffee. The analysis was conducted by identifying microbes microscopically and macroscopically. The results of microbial identification during the 30-day fermentation showed populations of yeast, lactic acid bacteria, and acetic acid bacteria. Along with the length of fermentation time, the temperature decreased and the pH fluctuated and stabilized after 16 days of fermentation. There was an increase in sugar and protein content, from 0.61% to 2.87% and 2.13% to 2.23%, respectively. The ethanol content reached 0.047% at the end of fermentation. The microbial exploration was required for further investigation in understanding its role during fermentation process.
