Özet
Günümüzde hastalıklar henüz ortaya çıkmadan, yaşam alışkanlıklarını değiştirerek hastalıkları önleyici ya da geciktirici yaklaşımlar gündemdedir. Beslenme alışkanlıklarının değiştirilmesi ve fonksiyonel gıdaların günlük diyete eklenmesi bu yaklaşımların en popülerleridir. Son yıllarda tüketiciler mağazaların kasa çıkışlarında, marketlerde, e-ticaret sitelerinde probiyotik atıştırmalıklar ve sıcak içeceklerle sıklıkla karşılaşmaktadır. Bu çalışma, süt ürünü olmayan probiyotik içeren atıştırmalıklar ve sıcak içeceklerdeki probiyotik mikroorganizma sayısını belirlemek ve ambalaj bilgileri ile karşılaştırmak amacıyla gerçekleştirilmiştir. Bu kapsamda ambalajında probiyotik ifadesi bulunan bar, granola, meyve topu, çikolata, çay ve kahve dahil toplam 28 örnek çeşitli market ve e-ticaret sitelerinden temin edilmiştir. Klasik mikrobiyolojik teknikler kullanılarak, etiket bilgilerinde yer alan Lactobacillus spp., Streptococcus spp., Bacillus spp. ve aerobik koloni sayısı spesifik besiyeri ve üreme ortam koşulları sağlanarak belirlenmiştir. Ambalaj bilgileri incelendiğinde sadece 7 örnekte (5 çay, 1 kahve, 1 bar) probiyotik mikroorganizma türü ve sayısının birlikte belirtildiği gözlenmiştir. 10 örneğin ambalaj bilgisinde probiyotik, probiyotik kültür gibi genel ifadelerin sayı belirtilmeden yer aldığı, 11 örneğin ambalajında ise sayı belirtilmeden spesifik probiyotik mikroorganizma adı kullanıldığı tespit edilmiştir. Mikrobiyolojik analizlerde, 8 örnekte (2 çay, 3 bar, 1 meyve topu, 2 çikolata) probiyotik ve ayrıca bu örneklerden 5’inde (2 çay, 1 bar, 2 çikolata) aerobik koloni sayısı tespit edilebilir seviyenin altında bulunmuştur. Ambalajında mikroorganizma türü ve sayısı belirtilen 2 çay ve 1 kahve örneğinin ambalaj bilgisinden düşük seviyede probiyotik mikroorganizma ihtiva ettiği ortaya konmuştur. Araştırmada incelenen probiyotik içerikli örneklerin %32.1’i (6 atıştırmalık ve 3 sıcak içecek) tek başına tüketildiğinde beklenen olumlu sağlık etkisini meydana getirecek düzeyde (>106 kob/g-mL) probiyotik mikroorganizma içermektedir. Bu araştırma sonucunda, tüketicilerin probiyotik içerikli yiyecek ve içecekleri tek başına değil gün içerisinde diğer probiyotik ve prebiyotik nitelikli ürünlerle kombine olarak ve düzenli kullanmalarının beklenen olumlu sağlık etkilerinin ortaya çıkmasına daha fazla yardımcı olacağı sonucuna varılmıştır.
Nowadays, approaches to prevent or delay diseases by changing life habits before diseases appear are in the spotlight. Changing eating habits and adding functional foods to the daily diet are the most popular approaches. In recent years, consumers have frequently encountered probiotic snacks and hot drinks at checkout counters, in markets, and e-commerce sites. This study was conducted to determine the number of probiotic microorganisms in non-dairy probiotic snacks and hot drinks and to compare them with the packaging information. In this purpose, a total of 28 samples, including bars, granola, fruit balls, chocolate, tea and coffee with the probiotic ingredient on their packaging, were purchased from various markets and e-commerce sites. Using classical microbiological techniques, Lactobacillus spp., Streptococcus spp., Bacillus spp., included in the packaging information, and aerobic colony count was determined by providing specific medium and growth environment conditions. When the packaging information was examined, it was observed that only in 7 samples (5 tea, 1 coffee, 1 bar) the type and number of probiotic microorganisms were stated together. It was determined that general expressions such as probiotic, probiotic culture were included in the packaging information of 10 samples without specifying a number, while the packaging of 11 samples were used the name of a specific probiotic microorganism without specifying a number. In microbiological analyses, probiotics were identified in 8 samples (2 tea, 3 bars, 1 fruit ball, 2 chocolates), and the total number of microorganisms in 5 of these samples (2 tea, 1 bar, 2 chocolates) was found below the detectable level. It was revealed that 2 tea and 1 coffee sample, with the type and number of microorganisms stated on the packaging, contained probiotic microorganisms at a lower level than the packaging information. 32.1% of the probiotic-base samples examined in the study (6 snacks and 3 hot drinks) contained probiotic microorganisms at a level (>106 cfu/g-mL) that would produce the expected positive health effect when consumed alone. As a result of this research, it has been concluded that consumers’ regular use of probiotic-containing snacks and hot drinks, not just on their own but in combination with other probiotic and prebiotic products throughout the day, will further contribute to the expected positive health effects
