FONKSİYONEL DONDURMA: ELMA, BAL KABAĞI VE PORTAKAL LİFİ İLE ZENGİNLEŞTİRME

Bu çalışmada elma, portakal ve bal kabağı meyvelerinden üretilen diyet liflerinin farklı konsantrasyonlarda (%1.5 ve %3.0) dondurma üretiminde kullanımının kalite ve besinsel özellikler üzerindeki etkisi araştırılmıştır. Elma, portakal ve balkabağı liflerinin kuru madde değerlerinin benzer olduğu, buna karşılık protein, kül, pH ve renk parametreleri (L*, a* ve b*) arasında farklılıkların bulunduğu görülmüştür. En yüksek su bağlama ile şişme kapasitesi değerleri bal kabağı lifinde, en yüksek çözünürlük değeri ile toplam fenolik ve flavonoid madde içerikleri ise elma lifinde belirlenmiştir. Genel olarak meyve lifi ilavesi dondurmaların kuru madde, protein, kül ve viskozite değerlerini artırırken pH, yağ ve hacim artışı değerlerini düşürmüştür. Meyve lifi ilavesi L* değerlerini azaltmış, a* ve b* değerlerinde ise artışa neden olmuştur. Tüm lifler ilave edilme oranlarına paralel olarak dondurmaların toplam fenolik ve flavonoid madde içeriklerini artırmıştır. Duyusal açıdan %1.5 oranında lif içeren örnekler daha fazla beğenilmiş ve balkabağı lifi içeren dondurmalar diğer çeşitlerden daha fazla tercih edilmiştir.

FUNCTIONAL ICE CREAM: ENRICHMENT WITH APPLE, PUMPKIN, AND ORANGE FIBER

In this study, the effect of using dietary fibers produced from apple, orange, and pumpkin fruits into ice cream production at two different concentrations (1.5% and 3.0%) on its quality and nutritional properties was investigated. The dry matter values of apple, orange, and pumpkin fibers were observed to be similar, but there were differences between each fiber’s protein, ash, pH, and color parameters (L*, a*, and b*). The highest water-binding and swelling capacity values were determined in pumpkin fiber, while the highest solubility and total phenolic and flavonoid substance contents were found in apple fiber. In general, the addition of fruit fiber increased the dry matter, protein, ash, and viscosity values of the ice creams while decreasing their pH, fat, and overrun. The addition of fruit fiber decreased L* values and increased a* and b* values. In parallel with the addition rates of all fibers, the total phenolic and flavonoid content of the ice creams increased. In terms of sensory, samples containing 1.5% fiber were more appreciated, and pumpkin fiber-containing ice creams were preferred more than other types.
