Ice green tea enriched with dried artichoke sepal tea infusion did not show any negative effect on panelists in terms of sensory scores and A4 samples were appreciated more other samples by most of the panelists.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:In this study, was to investigate effect of three different brewing times (5, 7 and 10 minutes) on some physicochemical (color, pH value, °Brix, türbidity, titratable acidity, total phenolic content, antiradical activity with DPPH) and sensory properties on ice green tea enriched with dried artichoke sepal at three different concentrations (3, 4 and 5%).
📊
Key Findings & Data:Higher artichoke bracts concentrations and longer brewing time increased total phenolic content of all samples.
💡
Conclusion & Impact:Ice green tea enriched with dried artichoke sepal tea infusion did not show any negative effect on panelists in terms of sensory scores and A4 samples were appreciated more other samples by most of the panelists.

Abstract

In this study, was to investigate effect of three different brewing times (5, 7 and 10 minutes) on some physicochemical (color, pH value, °Brix, türbidity, titratable acidity, total phenolic content, antiradical activity with DPPH) and sensory properties on ice green tea enriched with dried artichoke sepal at three different concentrations (3, 4 and 5%). As increasing of brewing times, ice tea samples were became mildly darker whereby resulted in lower brightness (L*) and redness (a*) values and in higher yellowness (b*) values. Higher artichoke bracts concentrations and longer brewing time increased total phenolic content of all samples. But this increment was associated with reduction pH value of medium and accordingly, turbidity and titratable acidity value of all samples were showed increment. Ice green tea enriched with dried artichoke sepal tea infusion did not show any negative effect on panelists in terms of sensory scores and A4 samples were appreciated more other samples by most of the panelists.

Özet

Bu çalışmada, kurutulmuş enginar çanak yapraklarından üretilen farklı konsantrasyonlarda (%3, 4 ve 5) enginaryaprağı katkılı limonlu soğuk yeşil çayların bazı fizikokimyasal (renk, pH değeri, briks, bulanıklık, titre edilebilir asitlik,toplam fenolik madde miktarı, DPPH ile antiradikal aktivite) ve duyusal kalite karakteristikleri üzerine infüzyonsüresinin (5, 7 ve 10 dakika) etkisi incelenmiştir. İnfüzyon süresinin artışıyla birlikte örneklerin parlaklık (L*) vekırmızılık (a*) değerlerinin azaldığı, sarılık (b*) değerinin ise arttığı görülmüştür. Soğuk çay bileşimindeki enginarkonsantrasyonun ve infüzyon süresinin artışına paralel olarak fenolik madde miktarı da artış göstermiştir. Bu artışlabirlikte ortamın pH değerinde düşüş, bulanıklık ve titre edilebilir asit miktarında ise artış gözlemlenmiştir. Farklıkonsantrasyonlarda enginar infüzyonu içeren soğuk çayların duyusal açıdan herhangi bir olumsuz bir durumoluşturmadığı ve A4 numaralı enginarlı-limonlu soğuk yeşil çayın daha çok tercih edildiği tespit edilmiştir.
