We investigated the effects of the amount of margarine and the number of layers on moisture content, baking loss, volume, hardness, maximum weight, and vapor action of the Danish pastry. The moisture content of Danish pastry increased slightly with the amount of margarine, as did the number of layers. The moisture content for a certain number of layers decreased as the amount of margarine increased. The baking loss with a fixed amount of margarine varied inversely with the number of layers, while the loss with a given number of layers decreased in proportion with the margarine content. The maximum volume of Danish pastry was obtained with 30% margarine-18 layers, 50%-27 layers, 70%-36 layers, 90%-48 layers and 110%-48 layers. The hardness and maximum weight of Danish pastry also varied inversely with the margarine content for a given number of layers, and decreased at a same margarine content when the number of layers increased. The maximum volume of the Danish pastry was obtained when vapor action was 9-16mm and 17-24mm. The optimal vapor action was in the range 9-24mm. In this range, the volume of the pastry was proportional to the vapor action.

This study was carried out to evaluate the effect of flour's protein contents on the quality of Danish pastries made with frozen doughs. Danish pastries for frozen dough were made by straight dough method. Frozen doughs were stored for 12 weeks at -20$^{\circ}C$ and baked after thawing and fermentation a month. The volume, the moisture content, the texture and the quality evaluation of Danish pastries were investigated. The volume of Danish pastry decreased with the increase of frozen storage time. Danish pastry made by flour of 13.2% protein content showed larger volume than that made by flour of 9.2% protein content. The moisture content of Danish pastry revealed that there were no significant decrease with the increase of frozen storage time. In terms of hardness, Danish pastry made by flour of 9.2% protein content accomplished the best texture in the resulting pastry. On the quality evaluation, Danish pastry made by flour of 13.2% protein content had the highest score.

Frozen doughs for danish pastries were made by straight dough method to study the effect of thawing temperature on the quality of pastries. Danish pastry doughs were immediately frozen at -40 $^{\circ}C$ quickly after make-up and stored for 6 weeks at -20$^{\circ}C$ and baked after thawing and fermentation a week. Thawing temperature and fermentation time were controled to 3 hr at 5$^{\circ}C$, 2 hr at 10$^{\circ}C$, and 1.5 hr at 20$^{\circ}C$, respectively. The number of survival yeast cells in dough and the volume, the moisture content, the texture of danish pastries were investigated. Survival yeast cells showed the highest number at thawing temperature of 5 $^{\circ}C$. The volume of danish pastries decreased significantly according to the increase of frozen storage time and danish pastries thawed at 5$^{\circ}C$ revealed the largest volume. In moisture contents of danish pastry, there was no significantly difference without regard to the thawing temperature but showed the highest moisture content at thawing temperature of 20$^{\circ}C$. Danish pastries thawed at 5$^{\circ}C$ accomplished the best texture in the resulting pastry.

The contents of the pastry margarine were 30, 50, 70, 90 and 110% based on baker's %, and the layers of the dough were 18, 27, 36, 48 and 64 in danish pastry product In order to analyse on the effect of the theoretical one layer thickness of the pastry margarine, the volume, quality and sensory evaluation of the products have been carried out. The results as follows ; 1) Best volume was showed that the thickness of the dough was 5mm and the thickness of one layer was 0.039mm. 2) When the content of the pastry margarine was 30% and the thickness of one layer was 0.014mm(48 layers), when 50%, 0.039mm(27 layers), when 70%, 0.038(36 layers), when 90%, 0.034(48 layers) and when 110%, 0.039(48 layers), best volume was showed. 3) In the case when the content of pastry margarine was 70% and the thickness of one layer was 0.038mm(36 layers), as well as 110%, 0.039mm(48 layers), the taste were showed 5%, better than when 30%, 0.014(27 layers) in the sensory evaluation. Flavor and mouth feel was the same results. 4) For the best quality products, the content of the pastry margarine and the layers of the dough were very important.

This study is carried out to investigate the effect of any periods in the freezer and the product of value, moisture content, baking loss, specific volume loaf in manufncturing process thereof. The moisture content of the croissant slightly decreased as the periods passed in the freezer. And as passed periods frozen croissant dough dried naturally by the freezer fan. 1. As frozen periods passed croissant dough decreased moisture content and loaf volume. The volume is relation to the molsture content and croissant dough' gluten. Yeast is active but croissant dough is dried so pastry margarine's moisture vaporized little by little. 2. 1 day frozen bench time provided maximum specific loaf volume while croissant shape was unsettled, moisture content was highest. At the same dough croissant hardness had very sofi crust. 3. 1week and 2weets frozen dough had specific loaf volume and hardness with proper crust color. As the proper bench time provided best shape of croissant, color. 4. 4weeks and 8weeks frozen dough had over-al] value of croissant accelerating older product. As the same result, over Sweets frozen periods product were not available for sale and serving to customers. 5. By the sensory evaluation tests, over-all croissant as 1 week, 2weeks were significantly higher quality those than 6. 1day, 4weeks and 8weeks. Textural properties of croissant over 4weeks frozen periods so hard for every panel. According to the study, not croissant dough but also any other frozen dough(ex.Danish, brioche etc.)have to need proper bench time and 1week or 2weeks circulation making method have to given encouragement to practical pastry industry. Add to this study using only for frozen dough yeast instead of using fresh and instant
