Research trends on gluten-free products and food safety: a bibliometric analysis

Abstract

Objective: The growing demand for gluten-free products items from both clinical necessities, such as celiac disease, and trends toward healthy eating. This has increased the significance of research on food safety and production processes. The present study aimed to identify research trends in gluten-free products and food safety using bibliometric analysis. Material and Method: Articles published between 2000 and 2025 were retrieved from the Web of Science database and analyzed through bibliometric methods. The bibliometrix and Biblioshiny packages in R were used to examine publication trends, authors, journals, and keywords, while author and institutional collaborations were visualized with VOSviewer. Results: A total of 573 articles were identified, showing a steady increase in publications over time. Since 2000, the number of publications has shown an increasing trend over the years, with the United States (n=4558), Italy (n=2143), and Spain (n=1116) identified as the three countries with the highest research output. The leading journals were Nutrients, Foods, and Food Control, and the most prolific authors included Catassi C., Zandonadi R.P., and Colgrave M.L. Keyword analysis revealed that the dominant research themes were “celiac disease,” “gluten contamination,” “food safety,” and “labeling.” Conclusion: In conclusion, the scientific productivity concerning gluten-free products and food safety is on the rise, necessitating that future studies diversify their methodology and comprehensively focus not only on the nutritional but also the technological and safety aspects of gluten-free foods.

Glutensiz ürünler ve gıda güvenliği üzerine araştırma eğilimleri: bibliyometrik bir analiz

Abstract

Amaç: Glutensiz ürünlere yönelik artan talep, hem çölyak hastalığı gibi klinik gereksinimlerden hem de sağlıklı beslenme eğilimlerinden kaynaklanmaktadır. Bu durum, gıda güvenliği ve üretim süreçlerine ilişkin araştırmaların önemini artırmıştır. Bu çalışma, glutensiz ürünler ve gıda güvenliği alanındaki küresel araştırma eğilimlerini belirlemek amacıyla bibliyometrik yöntemle gerçekleştirilmiştir. Gereç ve Yöntem: 2000-2025 yılları arasında glutensiz ürünler ve gıda güvenliği konularında yayınlanan makaleler Web of Science’tan alınarak bibliyometrik yöntemlerle analiz edilmiştir. Yayınlar, R ortamında bibliometrix ve Biblioshiny paketleri kullanılarak küresel yayın trendleri, yazarlar, dergiler ve anahtar kelimeler açısından incelenmiş; yazar ve kurum iş birlikleri VOSviewer ile görselleştirilmiştir. Bulgular: Arama sonucunda toplam 573 makale belirlenmiştir. 2000 yılından itibaren yayın sayısı yıllar içinde artış göstermiştir, ABD (n=4558), İtalya (n=2143) ve İspanya (n=1116) olmak üzere üç ülkenin en yüksek yayın üretimine sahip olduğu gözlenmiştir. En çok yayın yapan dergiler arasında sırasıyla Nutrients (n=32), Foods (n=21), Food Control yer almıştır. Yazarlar arasında Catassi C., Zandonadi R.P., Colgrave M.L. öne çıkmıştır. Anahtar kelime analizi, çalışmaların büyük ölçüde “çölyak hastalığı”, “gluten kontaminasyonu”, “gıda güvenliği” ve “etiketleme” temaları etrafında yoğunlaştığını göstermektedir. Sonuç: Sonuç olarak, glutensiz ürünler ve gıda güvenliği konusundaki bilimsel üretkenlik artmakta olup, gelecekteki çalışmalar metodolojiyi çeşitlendirerek, glutensiz gıdaların yalnızca besinsel değil, aynı zamanda teknolojik ve güvenlik boyutlarına da kapsamlı bir şekilde odaklanması gerekmektedir.
