Transglutaminaz enzimi (Tgaz); amin birleşmesi, çapraz bağ oluşumu ve deamidasyon tepkimeleri ile proteinleri modifiye edebilen bir enzimdir ( EC 2.3.2.13, protein-glutamin -glutamil-transferaz ). Tgaz kullanımıyla gıda işleme teknolojisinde, düşük viskoziteli protein çözelti ve/veya dispersiyonlarında jel yapı oluşturma, mekanik dayanımı artırma, düşük yağ – protein içeriğinde mekanik yapı oluşturma, var olan yapıya eksikliği duyulan amino asit katılımını sağlama, tekstürel deformasyonu ve gıda katkı maddeleri kulanımını azaltma veya tamamen ortadan kaldırma olasıdır.

Anahtar Kelimeler

Transglutaminaz, gıda, protein, çapraz bağlanma, tekstür, fonksiyonellik, katkı maddeleri

Applications of Transglutaminase in Food Industry: 1: General Properties of the Enzyme (Turkish with English Abstract)

Öz

Transglutaminase (Tgase) is an enzyme which catalyzes the reactions i.e. amin corporation, crosslinking and deamidation ( EC 2.3.2.13, protein-glutamine -glutamil-transferaz ). The gel formation in dilute protein dispersions or solutions, improvement of the mechanical strength, physical texture formation in dilute oil-protein dispersions, the corporation of aminoacids which were lack in the structure to the proteins, prevent the textural deformations, reducing the usage of the food additives will be possible with usage of tgase.
