By making white bread added extracts of degradation of enzyme of 50%, 75% and 100% alternatively instead of water when making dough for the purpose to examine the possibility to manufacture high value bread by adding functional ingredients of Hizikia fusiformis, it was examined physicochemical characteristics of white bread and the influence of food added dry matter of bread by 7.5% and 15.0% on contents of serum lipid and obesity index, rate of increase in body weight of obese white rat which was induced by high-fat diet. As for general ingredients of extracts of degradation of enzyme of Hizikia fusiformis, the contents of crude protein, crude fat, carbohydrate and ash were7.4%, 1.1%, 62.7% and 28.9%(dry matter basis) respectively, content of sulfate was 14.8%, content of uronic acid was 5.1%, and as for composition of sugars, it was in order of fucose was 41.3%, galactose 32.1%, mannitol 9.3% and glucose 3.8%. Contents of minerals among extracts of degradation of enzyme of Hizikia fusiformis were potassium 7,395.2 mg%, sodium 2,360.4 mg%, calcium 561.6 mg% and magnesium 411.7 mg%, and content of polyphenol was 1,064.3 mg%. As for the first fermentation time of dough, the control which used water 100% was the longest as 40.62 minutes, and the fermentation period of dough which was substituted 100% of extracts of degradation of enzyme of Hizikia fusiformis was 34.27 minutes, so it came to considerably shortened. As for the second fermentation time, the control was the longest as 29.26 minutes, and the more the additive contents of extracts of degradation of enzyme of Hizikia fusiformis, the shorter the fermentation time it was. As for water absorption of dough, the control was 63.7%, and water absorption of dough which was differentiated the additive contents of extracts of degradation of enzyme of Hizikia fusiformis was in the range of 63.1~63.8, there was few changes. The control which used water 100% when making dough started to form dough at 8.9 minutes, and there was special change although the additive contents of extracts of degradation of enzyme of Hizikia fusiformis was increased. The dough stability time of the control was 17.3 minutes, and when it was substituted extracts of degradation of enzyme of Hizikia fusiformis for 100%, it was 17.6 minutes, so there was seldom change of stability of dough although the additive contents of extracts of degradation of enzyme of Hizikia fusiformis was increased. In addition, the weakening of dough of the control was 12.4 B.U, when it was substituted extracts of degradation of enzyme of Hizikia fusiformis for 100%, it was 12.6 B.U, so there was seldom change of weakening of dough although the additive contents of extracts of degradation of enzyme of Hizikia fusiformis was increased. Shape factor showed similar tendency. As the additive contents of extracts of degradation of enzyme of Hizikia fusiformis was increased, the elongation and elongation resistance of dough were slightly changed, so it did not interrupt gluten formation when making dough. As for the temperature to start gelatinization, the control was 61.5℃, as the additive contents of extracts of degradation of enzyme of Hizikia fusiformis was increased, it became slightly lowered. As for the maximum viscosity temperature, the control was 93.6℃, and there was seldom change of weakening of dough although the additive contents of extracts of degradation of enzyme of Hizikia fusiformis was increased. Therefore, it had seldom influence on baking quality though extracts of degradation of enzyme of Hizikia fusiformis was added alternatively instead of water when making dough, As for water contents among general ingredients of bread, the control was the highest as 41.7%, and the more the additive contents of extracts of degradation of enzyme of Hizikia fusiformis, the water contents was slightly reduced. As for ash contents, the control was the lowest as 0.4%, and the more the additive contents of extracts of degradation of enzyme of Hizikia fusiformis, it was appeared high. As for contents of crude protein, the control was 3.9%, but as the additive contents of extracts of degradation of enzyme of Hizikia fusiformis, the content of protein was appeared a little low, and as for content of crude fat, the control was the highest, and though extracts of degradation of enzyme of Hizikia fusiformis was added, there was no special change of content of crude fat. As for the specific volume of bread, the control was 4.36 mL/g, so there was seldom change though the additive content of extracts of degradation of enzyme of Hizikia fusiformis was increased, and as for loaf volume index, it was same tendency with specific volume, but the cooking loss, it was reduced as the additive contents of extracts of degradation of enzyme of Hizikia fusiformis increased. As for the changes in color, as the additive contents of extracts of degradation of enzyme of Hizikia fusiformis increased, the value of L was reduced, the value of a was slightly increased, and the value of b showed almost constant value. Extracts of degradation of enzyme of Hizikia fusiformis had effect to increase elasticity slightly which is the major quality evaluation index of bread not to have great influence on hardness, fracturability and chewiness related to texture of bread. At sensory test, palability of female university students in 20s was rather reduced from color, smell, taste etc as the additive contents of extracts of degradation of enzyme of Hizikia fusiformis, but overall evaluation, the palability was slightly increased, so repulsion for the bread added extracts of degradation of enzyme of Hizikia fusiformis was not strong. Otherwise, palability of housewives in 40s increased in every item for bread group added extracts of degradation of enzyme of Hizikia fusiformis compared to the control, and especially the bread added extracts of degradation of enzyme of Hizikia fusiformis for 100% was evaluated the most excellent. For water holding capacity is increasing according to polysaccharide ingredients of extracts of degradation of enzyme of Hizikia fusiformis, it prevents water loss among preservation of bread and delays mould growth, so it had keep quality of bread. Body weight gain per day of diet group which took in food which was added 15% of powder of white bread made of extracts of degradation of enzyme of Hizikia fusiformis to high fat diet was reduced about 36.4% compared to obese control group, so it was estimated that reducing diet was occurred according to that indigestible polysaccharide or fibrin included in extracts of degradation of enzyme of Hizikia fusiformis reduced digestion and absorption of protein and fat among diet. Contents of neutral lipid, total lipid, total cholesterol and LDL-cholesterol among serum of diet group which took in diet added 15% of powder of bread made of extracts of degradation of enzyme of Hizikia fusiformis to high fat diet was appeared lower 36.8%, 40.4%, 36.4% and 68.5% respectively compared to obese control group, otherwise, contents of HDL-cholesterol was appeared higher 63.2%. Therefore, if extracts of degradation of enzyme of Hizikia fusiformis was used by being substituted water for 100% to dough, sensory palability was not reduced compared to control group which used water only as well as physical properties, baking quality, storage quality of dough were improved and it had effect to improve hyperlipidemia and obesity due to indigestible mucopolysaccharide or fibrin included in extracts of degradation of enzyme of Hizikia fusiformis.
