Special Issue Information

Dear Colleagues,

In recent years, the intake of food products composed of artificial compounds/additives has motivated many discussions owing to the potential adverse effects of these substances on consumer health. Therefore, many food companies have started to substitute these additives (chemically produced or chemically modified after extraction) with natural equivalents in order to meet current consumer expectations of safer and healthy foods. In this sense, functional foods and natural products constitute several compounds. Furthermore, many of them possess bioactive properties, such as antioxidant, anti-inflammatory, antimicrobial, antitumoral, and numerous supplementary properties. Bioactive compounds are chemical components that have been described as containing vitamins, minerals, fibers, sugars, and phenolic compounds with activities potentially beneficial to health, protecting against inflammatory chronic diseases such as diabetes, as well as cancers, ageing, and other conditions. Therefore, these bioactive molecules can be used as food supplements or additives for many foods to protect and promote health.

Garlic consumption is a well-known cause of unpleasant breath and body odour, with volatile organosulfur compounds, such as diallyl disulfide (DADS) and allyl methyl sulfide (AMS) responsible for the characteristic odour. Certain foods that are rich in polyphenols (PPs) and polyphenol oxidase (PPO) are known to deodorise garlic breath. However, no study into garlic body odour has been reported owing to the very low amounts of emitted volatile organosulfur compounds. Herein, we aimed to demonstrate the effects of ingesting natural food additives rich in both PPs and PPO on the emissions of skin-derived DADS and AMS using a passive flux sampler in conjunction with gas chromatography–mass spectrometry. Three healthy male subjects were subjected to garlic-consumption testing, with all subjects commonly observed to exhibit remarkably higher dermal DADS- and AMS-emission fluxes after consuming 45 g of cooked garlic, which then gradually decreased toward their initial baseline levels. In comparison, remarkably lower emission fluxes of both organosulfur compounds were observed after consuming a natural food additive following garlic consumption in a dose-dependent manner. The optimal amount of ingested natural food additive required to reduce garlic body odour was found to be 1–2 g. Considering the metabolic pathway associated with garlic-derived sulfur compounds and elimination reactions involving PPs and PPO, allyl mercaptan is likely to be a key substance involved in reducing garlic body odour through the ingestion of natural food additives.
