The study produced a functional sponge cake added with 0~20% proportion of excellently functional flaxseed powder aimed at obtaining basic data for the possibility to develop new products through a physiochemical properties assessment and a sensual assessment of the product. The water content was the lowest in the control, at 27.63%, and the 5~20% water content following the increase in added flaxseed powder failed to display a significant difference (p<0.05). The pH of the dough was 6.77~6.44, and displayed a significant difference according to the added amount of flaxseed powder (p<0.05). The specific weight of the dough appeared to be 0.40~0.51, and displayed a significant increase according to the added amount of flaxseed powder. The DPPH radical scavenging activity of the sponge cake added with flaxseed powder was 12.8%, and the plot added with flaxseed powder displayed a significantly higher percentage of 22.34~55.57% than the control plot. Crumb color change had increased values for value a and value b, and a significantly decreased L value. Texture significantly increased according to the increase in hardness, gumminess, chewiness, and cohesiveness, while springiness significantly decreased. Sensual assessment displayed a high preference for the 10% flaxseed powder additive plot in all items including appearance, taste, color, flaror, softness, and overall acceptability. The assessment of physiochemical properties and sensuality of the sponge cake added with flaxseed powder revealed that 10% flaxseed powder is suitable as the optimum proportion.

This study was conducted to investigate the quality characteristics of cookies added with different levels of flaxseed powder. Cookies were prepared with four different levels (0%, 6%, 12% and 18%) of flaxseed powder and the physicochemical properties were examined. The pH of cookie dough was higher in cookies containing flaxseed powder. The spread factor of control cookie was lower than that of cookies containing 6%, 12% and 18% of flaxseed powder. The incorporation of flaxseed powder in cookies lowered lightness and yellowness but increased redness values. Rheology testing showed that cookies with 6%, 12% and 18% flaxseed powder had significantly lower hardness value than control cookies (p < 0.05). Consumer acceptance test revealed that overall preference score was the highest in cookies containing 12% flaxseed powder. During storage at $55^{\circ}C$ for 60 days, peroxide value increased until 30 days of storage and decreased thereafter, while acid value steadily increased and there was no significant difference in peroxide value and acid value between control cookies and flaxseed added cookies.

The feasibility of incorporating flaxseed powder up to 8% (w/w) as a value-added food ingredient in convenient food products was investigated using pound cake as a model system. The moisture content, volume, height, and hardness of cakes decreased significantly with increasing levels of flaxseed powder (P<0.05). On the other hand, baking loss increased with higher flaxseed powder in the formulation (P<0.05). Lightness and yellowness decreased, whereas redness increased significantly (P<0.05). 1,1-Diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS) radical scavenging activities increased significantly (P<0.05), and they were well correlated. The consumer acceptance test indicated that addition of 2% flaxseed powder had the most favorable effect on consumer preferences in general. Based on the overall observation, pound cakes with 2% flaxseed powder is recommended to take advantage of its functional properties without sacrificing consumer acceptability.

An in vitro study was conducted to examine the effect of addition level of carbohydrates on fermentation characteristics, and bio-hydrogenation of unsaturated fatty acids by mixed rumen bacteria when incubated with soybean oil or flaxseed oil. Four levels(0%, 0.3%, 0.6% and 0.9%, w/v) of the mixed carbohydrates(glucose, cellobiose, soluble starch, 1:1:1, in weight basis) and oil sources(soybean or flaxseed oil, 60mg in 150ml culture solution) were added to the mixed solution of strained rumen fluid with artificial saliva(1:4, v/v), and incubated anaerobically for 12 hours at 39℃. pH and ammonia-N concentration were lower by increasing the substrate levels at all incubation periods(P<0.05～P<0.001). The propionate proportion increased(P<0.001), but acetic acid and butyric acid decreased(P<0.001) with the substrate level at 6 and 12 h incubations. Oil sources did not influence the proportions of individual VFA. At the end of incubation, the proportions of C18:0(P<0.01), C18:1(P<0.001) and trans-11C-18:1(P<0.01) were reduced but those of C18:2(P<0.001) and C18:3(P<0.01) were enhanced by the addition of flaxseed oil compared to addition of soybean oil. The proportions of C18:0 and total CLA were reduced(P<0.01) but those of trans-11-C18: (P<0.05) and C18:2(P<0.01) were increased with the substrate level when incubated with soybean oil or flaxseed oil. There were interactions(P<0.05) in the proportions of C18:1, C18:2 and C18:3(P<0.01) between oil source and substrate level. The proportions of cis-9, trans-11-CLA and trans-10, cis-12-CLA tended to reduce with substrate level, although there was no significant difference between treatments.
