E-NoseFlavNet: Sensör Dizisi Teknolojisi ile Çeşitli Makine Öğrenmesi Modelleriyle Güçlendirilmiş E Burun Tabanlı Aroma Lezzet Analizine Doğru

Öz

Gıda güvenliği için güvenilir aroma tespiti gereklidir, ancak geleneksel yöntemler (test kağıdı, kromatografi) doğruluk, hız, taşınabilirlik ve maliyet açısından yetersizdir. Bu çalışmada, aroma VOC analizi için istatistiksel yöntemler (t-SNE, MANOVA) ve makine öğrenmesi modellerini birleştiren sensör dizili bir E-burun sistemi önerilmiştir. Çikolata, karanfil, tarçın, zencefil ve aromasız olmak üzere beş sınıf incelenmiştir. Literatürdeki %95.73 doğruluk referansı ile Random Forest, ExtraTrees, XGBoost, CatBoost ve Stacking ensemble modelleri değerlendirilmiştir. Tüm modeller ikili testlerde çikolatayı mükemmel şekilde tespit etmiştir. Stacking aromasız sınıfında %50, diğer aromalarda %94'e kadar başarı göstermiştir. İstatistiksel yöntemler özellikle ikili testlerde belirgin VOC ayrımı sağlamıştır.

Anahtar Kelimeler

• Aroma Lezzet Analiz
• E Burun
• Makine Öğrenimi Modelleri
• İstatistiksel Ayrıştırma

E-NoseFlavNet: Towards E-Nose based Aroma Flavour Analysis Empowered by Diverse ML Models via Sensor Array Technology

Öz

Ensuring food-supply safety requires reliable aroma/flavour detection, yet conventional tools (test paper, cyclotron, chromatography) often lack accuracy, broad detection range, speed, portability, and low cost. We propose a sensor array electronic nose (E nose) for aroma VOC analysis and prediction, combining statistical visualization/discrimination (t SNE, MANOVA) with machine learning models. Five classes were studied: chocolate, clove, cinnamon, ginger, and an unflavoured VOC set. Using a literature benchmark of 95.73% accuracy, we evaluated Random Forest, ExtraTrees, XGBoost, CatBoost, and a Stacking ensemble for 5 class prediction and one vs rest tests. All models perfectly identified chocolate in one vs rest prediction. Stacking performed poorly for unflavoured vs others (50%), whereas other aromas reached up to 94%. Statistical methods showed clear VOC separation, especially in one vs rest analyses.
