The influence of storage time on authentication of plant-based foods
 Trödlerová, Martina ; Šislerová, Lucie (referee) ; Fialová, Lenka (advisor)
Fruit baby foods and purees belong among adulterated food, due to the prices of materials for their production. More expensive ingredients are replaced by cheaper, lower quality ones. This bachelor thesis deals with influence of storage time on the determination of samples authenticity The theoretical part of the thesis deals with the chemical composition of fruit (especially apples and peaches), production technology and methods of determining authenticity. In the experimental part, model samples were prepared and DNA was isolated from them. Then, using two different primer pairs, this DNA was amplified by real-time PCR and a specific product was detected by analyzing melting curves. On gel electrophoresis, it was possible to confirm the presence of these specific products. The last method was HPLC, where phenolic substances were analyzed.
