The development of food processing technology has increased the number and types of food products to meet human needs. The quality of a food product is not only seen from nutritional value and safety, but also from halalness aspect. For the purposes of quality control and halal authentication, the existence of a food testing method that is fast, accurate and easy to handling is needed. The application of electronic nose for various volatile compound detection purposes has been widely reported. This paper discusses electronic nose applications for quality control and halal testing purposes on food products. Furthermore, it also discussed the advantages and disadvantages of testing with an electronic nose. Based on the discussion, the electronic nose is a portable detection tool that is user friendly, fast and accurate for the identification and detection of food products based on the presence of the aroma of volatile compounds in the material. The advantages of this electronic nose have the potential to be used as an alternative rapid detection instrument in food testing, especially in authenticating pork and pig derivative.

Food fraud and adulteration are the global issues, currently. One important issue is about gelatine since it comes from many sources of animals. Therefore, analytical method for gelatine must be developed and used for the authentication. This study was conducted to investigate the Volatile Compounds (VCs) of gelatine and the Maillard Reaction Products (MRPs) which are responsible to their aroma. Three gelatine standards from bovine, fish and porcine bought from Sigma Aldrich were used. A high reactivity reducing sugar namely xylose was used in the Maillard Reaction (MR). A Solid Phase Micro Extraction-Gas Chromatography-Mass Spectroscopy (SPME-GC-MS) used to evaluate the VCs in the samples. The VCs were identified by comparing the mass spectra of the compounds with database of NIST library. Moreover, retention time using the n-Alkane index were compared with literature data. There were 67 VCs have been identified. Among them, furfural, acetic acid, nonanone, dimethyl disulphide and decanone were considered as the important volatiles in gelatine due to its abundance. In the MRPs, furfural, 1-(2-furanylmethyl)-1H-pyrrole, 1-(2-furanyl)- ethanone, acetic acid and 2,2’-bifuran were predominant. Additionally, heptanol, octanal, nonanal, nonanone, dimethyl disulphide and dimethyl trisulphide could be considered as the important compounds due to its low odour threshold value. The compounds had a direct influence on the overall aroma of samples and could be potential to use in gelatine differentiation.

Currently, the implementation of the Halal assurance system in Indonesia is mandatory. A side from food, pharmaceutical, cosmetics, and medicines must all be halal certified. Natural products, particularly marine-based products, are an alternative choice for the cosmetics and pharmaceutical industry's raw materials. Enhalus acoroides are common along Indonesia's coasts and have the potential to be used as raw materials in halal cosmetics and pharmaceutical products. The purpose of this paper is to examine the potential of E. acoroides samples collected from various locations in Indonesia in terms of bioactive compounds and their applications. Secondary metabolites namely alkaloids, flavonoids, polyphenols, steroids, triterpenes, and tannins have been reported in E. acoroides extract from Indonesia, and they have the potential to be used as antibacterial, antiaging, antiviral, antitumor, and antioxidant in the pharmaceutical and cosmetic industries in Indonesia
