Abstract

Halal food is taken into account as any food permitted to be consumed by Muslim according to Syariah law. Due to the development of science and technology in which some new food components such as food additives have been synthesized and produced, some industries used non-halal components such as pig derivatives in food products to reduce the production cost. Non-halal components added in food products are difficult to detect visually due to the close similarity between non-halal ingredients and components present in food. As a consequence, some scientists developed and proposed some instrumental techniques like spectroscopy, chromatography and molecular biology-based methods for identification of non-halal components. Food matrix is very complex to be analyzed. Therefore, the signals obtained during chemical and biological analyses are very complex which are difficult to interpret. Fortunately, a statistical technique called with chemometrics can be used an alternative method to handle the complex data met during analysis of non-halal components. Chemometrics has been widely used in many aspects of analysis in many types of the sector. In this review, some chemometrics techniques used to treat responses obtained from instrumental measurements intended for analysis of non-halal components in food matrix were highlighted.

Abstract

Spectroscopic method in the UV-Vis region is considered the most molecular spectrometric method for content determination of a single component. However, a lot of pharmaceutical dosage forms comprise two or more components which lead to peak overlapping. Moreover, in the chemical stability test, active pharmaceutical ingredient (API) was also found along with the degradation products, impurities, and adulterant compounds. UV-Vis spectroscopy is one of the methods of choice for the determination or quantification of a single component in pharmaceutical preparations. The pharmaceutical products typically contain two or more APIs having chromophoric agents capable of absorbing UV-Vis beams and the absorbance values are summative from the absorption of each UV-Vis active compound according to the additive nature of Lambert-Beer law. The main problem for the simultaneous determination of API along with impurities and the degradation products in pharmaceutical preparations is the presence of overlapping peaks of UV-Vis spectra. The chemometrics-assisted spectroscopy is one of the analytical efforts to solve these problems. This review highlighted the application of chemometrics in combination with UV-Vis spectroscopy for the assay of API, impurities, adulteration issues and degradation products present in pharmaceutical dosage forms.

Abstract

Apart from being rich in culture, Indonesia is also rich in food culture. However, in some cases, there are illegal additions of formalin (37% formaldehyde) to food to extend shelf life. If humans consume food containing formaldehyde, it will have a harmful impact. Formaldehyde has the potential to cause cancer. In recent years, formaldehyde has still been found in several Indonesian foods. There are several analytical methods developed to detect formaldehyde levels in food. This review overview of the formaldehyde effect to human health, formaldehyde content in fish and Indonesian food, and the detection methods.

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

The oil extracted from Pangasius micronemus, commonly known as patin fish, is highly regarded for its omega-3 and omega-6 fatty acids content, which offer numerous health benefits. Producing high-quality patin fish oil (PFO) rich in these essential fatty acids requires an optimized extraction process. This study utilized ultrasound-assisted extraction (UAE) combined with response surface methodology – Box Behnken Design (RSM-BBD) to optimize the extraction of PFO. Five variables were examined: temperature (30–60 °C), solvent composition (n-hexane in isopropanol, 30–90%), amplitude (30–90%), solvent-to-sample ratio (10:1–20:1), and cycle duration (0.2–0.8 s−1). The analysis identified solvent composition, amplitude, and solvent-to-sample ratio as significant factors influencing the response value (p < 0.005). Optimal UAE conditions were achieved at a temperature of 59 °C, solvent composition of 42%, amplitude of 41%, solvent-to-sample ratio of 20:1, cycle duration of 0.8 s−1, and an extraction time of 25 min. Fatty acid profiling revealed that PFO extracted using UAE contained omega-3 fatty acids, including α-linolenic acid (ALA) at 1.36% and eicosapentaenoic acid (EPA) at 0.46%, as well as omega-6 fatty acids, namely linoleic acid (LA) at 19.06% and arachidonic acid (AA) at 0.85%. These results demonstrate the efficiency of UAE in extracting high-quality PFO.

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.
