In order to improve the storage stability of steamed bread, fermented pine needle extract syrup potentially with several functional properties was added in manufacturing the products at levels of 8.3, 11 and 18% based on Brix degree of the dough. The manufactured bread was stored at ambient conditions and measured for quality attributes. Dough added with the fermented pine needle extract syrup maintained its pH and water activity at levels of $5.45{sim}5.90;and;0.94{sim}0.96$, which are normally suitable for yeast fermentation and for appropriate dough hardness. Addition of the extract syrup increased the bread volume by more than 20%. The bread with higher content of the pine needle extract syrup showed slower increase of bread hardness during storage, suggesting retardation of bread retrogradation. The addition of the pine needle extract syrup in bread dough also inhibited growth of the aerobic bacteria and molds on the bread surface (by $0.8{sim}24$ in log (CFU/g) at 4 day storage). Use of higher than 11% concentration presented initially a strong fine needle flavor to the bread, which disappeared soon after 2 days. Generally addition of the pine needle extract syrup did not give negative effects on the bread quality including sensory quality. Therefore, the addition of the needle extract syrup could contribute to improving the storage stability and extending the shelf life of the bread.
