AB - The current study aimed at evaluating the antifungal activity of thyme (Thymus vulgaris L.) essential oil (EO) and its hydrosol and propolis extract (PE) against natural mycobiota on the surface of sucuk. Yeast–mold (YM) counts of sucuk samples treated with hydrosol and control were above 7.0 log cfu/g. However, they were 2.59, 5.02 and 5.41 log cfu/g in samples treated with potassium sorbate (PS), EO and PE, respectively. PS, EO and PE provided reductions of 4.88, 2.45 and 2.05 log cfu/g in YM counts compared with control treatment, respectively. Lactic acid bacteria and aerobic mesophilic bacteria results of the sucuks treated with the extracts were similar in the end of ripening period. Surface treatments did not adversely affect the color of sucuks. A total of 77 volatile compounds were isolated and identified in the sucuks. The major group of volatile compounds found in the sucuk samples was terpenes. Practical Applications Sucuk, a traditional fermented dry‐cured sausage, is one of the most consumed meat products in Turkey. It is produced using two different methods, namely traditional and industrial. Molding is an important problem in the sucuk produced by traditional method as sucuk may be contaminated by fungi in the production area and/or fermentation chamber. In recent years, the use of natural antimicrobial agents, such as plant essential oils and/or extracts, propolis against pathogenic bacteria, and undesirable microorganisms in foods, has increased. Essential oil and propolis have antimicrobial effects. These natural antimicrobial agents can be used as an antifungal agent for food industry such as dairy and meat. This study can help prevent fungi growing on the surface of foods.
