Fenilketonüri Hastaları İçin Maviyemiş (Vaccinium corymbosum L.) İçeren Toz Puding Karışımı Üretimi

Bu çalışmada, fenilketonüri hastaları için kazeinomakropeptit (KMP) ve kurutulmuş maviyemiş (Vaccinium corymbosum L.) içeren toz puding karışımı geliştirilmiştir. Bu amaçla, amino asit diziliminde fenilalanin (Phe) bulunmayan kazeinomakropeptit (KMP), peynir altı suyundan izole edilerek protein kaynağı olarak kullanılmıştır. Elde edilen liyofilize izolattaki KMP oranı %57.56±0.18 olarak bulunmuştur. KMP verimi ise %71.22±0.21 olarak hesaplanmıştır. Farklı oranlarda (%10, 12 veya 15) KMP izolatı ve kurutulmuş maviyemiş (%10 veya 15) içeren altı farklı toz puding karışımından duyusal özellikler ve viskozite açısından en uygun formülasyonun %15 KMP izolatı ve %15 kurutulmuş maviyemiş içeren puding olduğu belirlenmiştir. Toz karışım ve pişmiş pudingin Phe ve tirozin (Tyr) içerikleri sırasıyla 134.05mg Phe/100 g, 478.73 mg Tyr/100 g ve 32.39 mg Phe/100 g, 106.41 mg Tyr/ 100 g olarak saptanmıştır.

Production of Pudding Mix Containing Dried Blueberries (Vaccinium corymbosum L.) for Phenylketonuria Patients

In this study, pudding mix containing dried blueberry (Vaccinium corymbosum L.) and caseinomacropeptide (CMP) was developed for phenylketonuria patients. CMP, having no phenylalanine (Phe) in its amino acid sequence, was isolated from sweet whey as a protein source. The percentage of CMP in the lyophilized isolate was 57.56 ± 0.18%. The yield of CMP was 71.22 ± 0.21%. Six different pudding mixes were prepared by the addition of different proportions of CMP isolate (10, 12 or 15%) and different amounts of dried blueberries (10 or 15%). The formulation containing 15% CMP isolate and 15% dried blueberries was chosen as the best formulation according to the results of sensory evaluation and viscosity analysis. Phenylalanine and tyrosine (Tyr) contents of pudding mix and cooked pudding were 134.05 mg Phe/100 g, 478.73 mg Tyr/100 g and 32.39 mg Phe/100 g, 106.41 mg Tyr/ 100 g, respectively.
