Abstract

Mount Ijen is a prominent region for peaberry Robusta coffee beans, which has entered international markets. Accurate real-time estimation of its chemical components is crucial for export activities. This study evaluated moisture content, lipid, and caffeine in Robusta peaberry coffee beans from Ijen using FT-NIRS (Fourier Transform – Near Infrared Spectroscopy). A total of 50 samples were scanned in triplicate, generating 150 spectral data points. The data were optimized for wavelength selection and pre-treated using Standard Normal Variate Transformation (SNV), Second Derivative (dg2), Multiplicative Scatter Correction (MSC), and normalization. Results showed that FT-NIRS proved effective for rapid and accurate estimation of these components. The best calibration model used Kubelka-Munk transformation with dg2 pre-treatment in the 1000-2500 nm wavelength range. Optimal Partial Least Squares (PLS) factors were PLS 4 for lipid content (R2 = 0.98, SEP = 0.013%, SEC = 0.012%, CV = 0.81, RPD = 2.03, consistency = 95.21%), PLS 5 for moisture content (R2 = 0.94, SEP = 0.014%, SEC = 0.014%, CV = 0.80, RPD = 4.88, consistency = 101.02%), and PLS 5 for caffeine content (R2 = 0.94, SEP = 0.014%, SEC = 0.014%, CV = 0.80, RPD = 4.88, consistency = 101.02%). Keywords: Absorbance, Caffeine, Lipid, Moisture Content, Pre-Treatment.

Abstract

The use of formalin as a food preservative is still common today. One type of food that is mixed with formaldehyde preservatives is cilok. There is a simple way without using chemicals to detect the formaldehyde content in cilok, namely using red dragon fruit skin. Red dragon fruit skin is waste that is not utilized and has the potential to provide natural coloring to food. Anthocyanin is a type of compound that reacts easily when mixed with acid or base compounds. The anthocyanin content in dragon fruit skin can identify the presence of formalin compounds in food. Anthocyanin has the same strong acid properties as formalin so when anthocyanin meets formalin, the formalin content can be easily observed organoleptically. This study aims to determine the formalin content in cilok taken in Rogojampi District in as many as 19 samples using a cross-sectional study method. The test results showed that the samples tested were negative or did not contain formalin.

Abstract

Catfish is a type of freshwater fish that is most widely cultivated by people because it has a high nutritional content and is also easy to cultivate. Catfish easily experience a decline in quality caused by lipid oxidation, protein degradation, and also microbial contamination. One effort that can be made to maintain the shelf life of catfish is by smoking. Smooking is often carried out using various types of smoking media, including wood, coconut shells, coconut husks, and rice husks. However, it is not yet known how long the smoking time is appropriate to produce smoked catfish with good organoleptic and chemical qualities. Therefore, this research was conducted to determine the appropriate length of time for smoking catfish regarding organoleptic quality, water, and protein content. The research was conducted using a 2 Factor Completely Randomized Design, where the first factor was the type of media including wood (P1), coconut shell (P2), coconut husks (P3), and rice husks (P4), and the second factor was the length of time smoked. includes a smoking time of 2 hours (L2) and a smoking time of 3.5 hours (L3). The results showed that different smoking media treatments and smoking duration had a significant influence on the physicochemical and organoleptic properties of smoked African catfish at a fairly large level (p < 0.05). The best treatment is smoking using coconut shell media for 2 hours duration (P2L2) which has the highest protein content of 23.30% and has the best organoleptic quality of color, aroma, taste, and texture. Meanwhile, the water content of smoked catfish is 49.70-56.46%, where the water content obtained in this study does not exceed the threshold set by BSN, namely a maximum of 60%.

Abstract

Cooking oil is an important food ingredient for Indonesians, but in recent years, oil shortages have caused significant price increases. Therefore, this research tries to utilize peanuts to produce oil that can be used in daily activities, especially in the kitchen, as well as testing its characteristics in accordance with bio-oil quality standards. The research method used was experimental by testing the effect of roasting time on various characteristics of peanut oil, including water content, viscosity and free fatty acid content. The results showed that roasting time had a significant effect on all parameters tested. A roasting time of 25 minutes produces peanut oil with a low moisture content (3.3%) and a lower viscosity (44.5 cP). Although the quality of peanut oil in terms of moisture content and viscosity is classified as good, the free fatty acid content test shows that P3 with a duration of 45 minutes has a free fatty acid content of 11.7% which exceeds the threshold according to the SNI standard for cooking oil, namely 2 %.
