The authenticity of halal meat is a global issue because pork adulteration occurs. Certain religions, such as Islam and Judaism, prohibit the use of pork in food products. The purpose of this study was to evaluate the volume of trypsin with 10, 50 and 100 μL (20 μg/100 μL) and the digestion time from overnight to 30-120 min to establish a fast and straightforward procedure on proteomic analysis for halal authentication of meat and meat products.

- Consumer awareness of food adulteration has risen, with unethical meat producers blending halal beef with rat meat for profit.
- This study introduces a real-time polymerase chain reaction (RT-PCR) method to detect rat meat in beef meatballs, involving several technical stages including primer design and DNA analysis.
- The validated RT-PCR method showed high specificity and sensitivity, successfully confirming no rat meat DNA in the tested beef meatball samples, providing a reliable halal authentication tool.
Objective: Meatballs are a popular meat-based food consumed widely in Indonesian society. However, the issue of unethical substitution of halal meatballs with non-halal meats, particularly pork and canine meat (CM), has emerged. The existence of non-halal meats, including CM, in food products is prohibited in Islam, necessitating the development of reliable analytical techniques for their identification.

- This study reviewed how nitrate supplementation affects blood oxygen levels, specifically focusing on lowlanders in high-altitude settings.
- The researchers analyzed data from 7 trials, revealing that while some studies indicated a slight improvement in oxygen levels during exercise at simulated altitudes, others showed a decline during rest at real high altitudes.
- Overall, nitrate supplementation didn't help prevent Acute Mountain Sickness and had mixed results for oxygen saturation, suggesting the need for more research to clarify these effects.
Background: 1,4-Dioxane (1,4-D) is a byproduct of the synthesis of surfactants, typically found in some cosmetics products such as shampoo, toothpaste, and soap. The presence of 1,4-D in cosmetics products is limited to a certain amount since 1,4-D is classified as a probable human carcinogen.
Objective: This present study was intended to validate static headspace gas chromatography-mass spectrometry (HS GC-MS) for the determination of 1,4-D in cosmetics products.
