Abstract

Keamanan pangan adalah kondisi dan upaya yang diperlukan untuk mencegah pangan dari cemaran biologis, kimia dan benda fisik yang dapat membahayakan kesehatan manusia. Terdapat bahan tambahan makanan yang dilarangkarena dapat memberikan dampak buruk terhadap kesehatan antara lain pewarna rhodhamine, methanil yellow, dan formalin. Penyuluhan adalah salah satu metode untuk meningkatkan pengetahuan. Tujuan dari pengabdian kepada masyarakat ini adalah mengedukasi siswa sekolah menengah pertama (SMP) sebagai kadar keamanan makanan dan mengevaluasi tingkat pemahaman siswa SMP setelah penyuluhan menggunakan pretest dan posttest. Uji Wilcoxon dengan tingkat kepercayaan 95% menunjukan perbedaan siginifikan antara pretest dan posttest. Peningkatan pengetahuan pada nilai rata-rata pretest dan posttest siswa adalah 39,34%.

Abstract

Garlic is a plant with numerous benefits, including its use as a culinary ingredient and for medicinal purposes. However, the rising demand does not align with the availability of garlic in Indonesia, resulting in high garlic prices. Excessively high prices may potentially lead to garlic powder adulteration. The objective of this study is to determine whether there are garlic powder products adulterated with maltodextrin in the Marketplace. A total of 10 garlic powder samples were purchased on Marketplace. The study utilized a combination of FTIR spectroscopy with chemometrics. The chemometrics employed in this study were OPLS-DA (Orthogonal Partial Least Squares Discriminant Analysis) for sample grouping, as well as PLS (Partial Least Squares) for multivariate calibration. The findings revealed that OPLS-DA could effectively group the samples. Additionally, the best multivariate calibration model (PLS) was obtained at the wavenumber range of 679-440 cm-1 with a calibration R2 value of 0.9981, RMSEC value of 1.11, validation R2 value of 0.9926, and RMSEP value of 2.12. Based on the research results, it was found that three products were not pure garlic powder, with details indicating two products containing maltodextrin as an adulterant and one product containing a non-maltodextrin adulterant.

Abstract

Turmeric powder (Curcuma longa L.) is often used for food coloring and flavoring. The high demand for turmeric powder has led to adulteration, one of which is metanil yellow. This study aims to detect metanil yellow dye in turmeric powder using Infrared Spectroscopy (FT-IR) and Chemometrics. The chemometrics model was built by preparing turmeric powder and metanil yellow in the concentration range of 0-50% (w/w). Data was processed using multivariate calibration using OPLS-DA (Orthogonal Partial Least Squares Discriminant Analysis) and PLS (Partial Last Square). The results obtained from OPLS-DA processing of market samples 1 and 2 are estimated to be pure turmeric powder, and samples 3 to 10 are adulterated. From the PLS results, the best calibration model was obtained at wave numbers 1199-539 cm-1 with R2 values for calibration and validation of 0.9967 and 0.9970, respectively, with RMSEC of 2.48 and RMSEP of 6.35. The PLS results showed that in sample 3 containing metanil yellow, in samples 4 to 10, no metanil yellow was detected. The ingredients added were not metanil yellow. It was concluded that FTIR combined with chemometrics could detect the metanil yellow in turmeric powder.
