Anthocyanin is pigment cluster red until blue colored that spread on plant. The most of anthocyanin to experience changes saving and processing. Factors that to influence anthocyanin stability are pH, temperature, ray, oxigen with another factor such as enzime and metal ion. At practice field application product have various of pH and different sugar sort, sugar sort that most used at processing industry such as glucose, sucrose and sorbitol. The aim purpose to do it of research isto knowing what the combination of pH and sugar sort influential against red rose flower anthocyanin pigment stability, to knowing sugar sort influence against red rose flower pigment stability. This research be starting with extraction of red rose flower crown untill getting of anthocyanin concentrate. Then doing experiment of pigment and red rose consentrate stability trial against 2 treatment factors that arranging according to factorial, with using RAK experiment sheme. First factor is pH various with 4 level ( pH 3, pH 4, pH 5 and pH 6) and second factor is sugar sort using 3 level (glucose, sucrose and sorbotol) as much as 40% with 3 time repeating. The research result showing that to happen of interaction between pH various and sugar sort against absorbating and total of soluted solid and happen not interaction against pH value, L value and + a value. Different sugar sort influential at L value. Buffer pH 3 adding with sucrose sugar have higgest absorbating that is 0,50 and lowest absorbating value at pH 6 buffer with sorbitol sugar is o,16. For pH 4 buffer adding with sucrose sugar have highest total value of soluted solid that is 48,28% and the lowest is pH 4 buffer treatment with sorbitol sugar is 36,07%.
