Total phenolic contents in sponge cake with different concentrations of the leaves of lemon balm
Background & Aim: Nowdays consumers prefer to eat healthier foods, therefore producers and researchers are involved to improve the variety, quality, taste of food products. Lemon balm is a perennial, aromatic, herb that contains many phenolic compounds. In this research the effect of additing lemon balm powder (by reducing of wheat flour in formulation, instead) on qualities of sponge cakes wer...

متن کاملBiochemical and genomic analysis of sucrose metabolism during coffee (Coffea arabica) fruit development.
Sucrose metabolism and the role of sucrose synthase were investigated in the fruit tissues (pericarp, perisperm, and endosperm) of Coffea arabica during development. Acid invertase, sucrose phosphate synthase, and sucrose synthase activities were monitored and compared with the levels of sucrose and reducing sugars. Among these enzymes, sucrose synthase showed the highest activities during the ...
متن کاملBiosynthesis of Caffeine in Leaves of Coffee.
The levels of endogenous caffeine and theobromine were much higher in buds and young leaves of Coffea arabica L. cv Kent than in fully developed leaves. Biosynthesis of caffeine from 14C-labeled adenine, guanine, xanthosine, and theobromine was observed, whereas other studies (H. Ashihara, A.M. Monteiro, T. Moritz, F.M. Gillies, A. Crozier [1996] Planta 198: 334-339) have indicated that there i...
متن کاملEffect of Pulsed Ultraviolet Light on the Total Phenol Content of Elderberry (Sambucus nigra) Fruit
The changes in total polyphenolics in elderberry (Sambucus nigra) following treatment with various doses of pulsed ultraviolet rays (UV) were investigated. Four pulsed UV durations (5, 10, 20, 30 seconds) at three energy dosages (4500, 6000, 11,000 J/m/pulse) were considered for the research. All treated elderberry fruits were incubated for 24 h at room temperature (25 ̊C) following treatment to...
