Abstract

Food safety is a critical issue in ensuring public health, especially in preventing contamination from harmful substances illegally added to food. One such hazardous additive is borax, which is sometimes used by unscrupulous food producers to preserve texture and shelf life, despite its known toxicity and prohibition in food products. This study aims to detect the presence of borax in tofu, a widely consumed protein source, by utilizing two analytical tools such as a Texture Analyzer and a Spectrometer. The Texture Analyzer was employed to evaluate the physical firmness of tofu, as borax is known to increase its hardness. The Spectrometer was used to confirm the chemical presence of borax. Results indicated that tofu samples containing borax showed significantly firmer textures compared to control samples, and the spectrometric analysis successfully detected borax compounds. These findings demonstrate that both instruments are effective in identifying borax contamination. The study recommends the sustainable development of rapid and accurate detection methods for other hazardous additives to enhance food safety monitoring and enforcement practices.

Review

This study addresses a critical public health concern by focusing on the detection of borax, a prohibited and toxic additive, in tofu—a widely consumed food product. The paper's strength lies in its innovative dual-method approach, combining a Texture Analyzer with a Spectrometer to identify borax contamination. This multi-faceted strategy promises to offer a more robust and reliable system for food safety monitoring, moving beyond single-technique analyses and highlighting the physical and chemical indicators of contamination. The methodology is logically structured, utilizing the Texture Analyzer to quantify the physical changes (increased firmness) induced by borax in tofu, a well-known effect of this additive. This physical assessment serves as a valuable preliminary indicator. Crucially, the Spectrometer is then employed for direct chemical confirmation, ensuring that the detected textural changes are indeed attributable to the presence of borax compounds. The abstract clearly indicates that both instruments successfully identified borax contamination, with samples containing borax exhibiting significantly firmer textures and positive spectrometric detection, thereby validating the efficacy of both methods. While the study presents a promising approach, the abstract could benefit from providing more specific details regarding the type of spectrometer utilized (e.g., FTIR, UV-Vis, ICP-OES), which would allow for a more thorough evaluation of its sensitivity, specificity, and practical applicability. Additionally, expanding on the quantitative correlation between borax concentration and the observed textural changes, and comparing the methods against existing standard detection protocols, would further strengthen the findings. Nevertheless, this research provides a significant step forward in developing integrated, rapid, and accurate detection methods for hazardous food additives, laying a strong foundation for improved food safety monitoring and enforcement practices as recommended by the authors.
