제과$\cdot$제빵분야는 대표적인 내수업종이고 보수적 업종성격이 강하다고 볼 수 있다. 연간 성장률이 $30\~40\%$대의 고성장을 구가하던 과거의 좋은 시기도 있었다. 현재 우리가 처한 $\$1$만 소득에서 $\$2$만 소득으로 가는 길목에서 이 분야는 기호식품으로 완전히 변해 있다고 볼 수 있다. 저성장 내지 마이너스 성장도 올 수 있는 시대에 이미 진입했다고 볼 수 있다. 소비자의 기호를 적극적으로 반영치 못한 제품은 시장에서 생존이 어려운 시대를 이미 맞고 있고, 이러한 현상은 차후 더 심하고 세차게 진행되어 질 것이다. 엄밀히 말해 기존의 제품운영계획 그대로 진행하면 그런 기업은 퇴보하게 되어있다고 생각된다. 또 다른 말로 표현하면 이제는 제과$\cdot$제빵 산업은 과감한 변신이 없다면 이미 사양산업화 되어지고 있다고도 볼 수 있다. 과감한 변신은 무엇일까? 소비자 욕구를 정확히 파악하고 이에 부응한 제품운영계획을 충실하게 세워 시행하는 것이다. 세부적으로는, (1) 제품내용물에 좋은 기능성을 도입시키는 것이다. 소위 건강에 좋다는 각종 원료성분들을 사용한 제품을 개발하여서 생산, 판매하는 전략이다. (2) 제품의 포장의 질을 좋게 하고 고급화 시킬 필요가 있다고 본다. BT를 응용한 첨단 포장기술 도입실행이 필요하다. 소비자에게 좋은 이미지를 줄 수 있고, 포장본래의 기능 제품보호가 완벽해야 하고 사용하기에 편리하여야 한다는 것이다. (3) 외국 제품들과의 경쟁은 필수적이다. 가공식품 분야는 이제 거의 $100\%$ 시장이 개방된 상태를 맞고 있다. 외국의 고기능성 내지 고급화제품들과의 경쟁은 피할수 없는 현실을 맞고 있다. 외국시장의 정보를 면밀히 분석하고 이에 대한 대응전략은 물론 더 나아가서 외국제품을 능가 할 경쟁력있는 제품개발이 필요하다고 판단된다. R&D 분야에 투자를 필연적으로 늘여야만 한다. 국내 식품사들의 Ramp;D 투자금액이 구미선진국이 1/10이하 수준에 머물고 있는 것이 오늘날 우리들의 실정이기 때문이다. 일본 등과 FTA 협정쳬결 논의가 국가적과제로 추진되고 있는 현재의 상황에서 이에 대한 우리업계의 대응전략을 지금부터 착수하여야 할 때라고 판단된다. 기본부터 철저히 우리의 장점을 살린 실질적 대응책 마련에 많은 지혜를 발휘할 때 우리 식품산업이 대내외적으로 경쟁력을 가질수 있다고 예상된다. 이러한 상황을 미루어 볼때에 고부가가치 제품을 창출 할 수 있는 여러가지 방안을 기업과 학계 그리고 정부가 종합적으로 강구하여야 할 때인 것이다. 필자는 이에 관한 몇 가지 방안들을 제안하였다.

Generic HACCP models for bakery products may help HACCP implementation at the wholesale bakery production lines easier. When baking, the internal temperature of bakery products went up to $85^{\circ}C$, which resulted in gelatinization of starch. Considering the characteristics of bakery products, general sanitation control procedures are the main target tool to keep bakery products safe. Monitoring of pathogenic microorganisms at bakery plant environment including production lines was carried out. At the wholesale bakery environment pathogenic microorganisms were detected. It gave a clue that general sanitation control procedures should be implemented for safe bakery products supply. Hazard analysis of raw materials and processing of bakery products, and determination of critical control points and critical limits at the wholesale bakeries lead to present generic model of bakery product HACCP plan. CCPs for the wholesale bakery products may be applied and modified for the implementation of HACCP plan at the wholesale bakery plant.

Breads were prepared with the addition of sprouted brown rice flour(SBRF) as a funtional ingredient up to 50%, and their quality characteristics were evaluated through analyses of proximate composition amino acid by HPLC, fatty acid by GC, and sensory evaluation. The optimum amount of SBRF for bread preparation was 30%(w/w). The more SBRF was added, the greater the proximate components such as ash, crude protein, crude fat, fiber and amino acid content were, although the baking quality such as volume decreased. The results of sensory evaluation for bread showed that the more SBRF was added, the lower the scores of color, appearance. texture and the feelings in the mouth were, but the higher the score of taste.

The effects of GOD and yeast on glucose content and pH of broiler and porcine blood plasma were investigated. The initial glucose concentration of broiler and porcine blood plasma were $150mg/100cm^{3}\;and\;143mg/100cm^{3}$, respectively. Addition of GOD and yeast decreased glucose contents in broiler and porcine plasma. As expected, plasma glucose content decreased as incubation time increased. While 1080 and 1110 min were required to remove glucose from both broiler and porcine plasma at GOD 5 units/g and 480 and 1020 min were required at GOD 10 units/g, respectively; both required 240 min at 0.3% yeast (w/w). The Maillard reaction can be prevented by desugarization. During the removal of glucose, pH of the plasma decreased. As glucose content in plasma leveled off, the pH value of plasma increased. Therefore, pH may be used as an index of desugarization.

Effects of olive oil on rheological properties of wheat flour dough were investigated through farinograph, amylograph, and extensograph, and by measuring wheat flour dough fermentation volume. Farinogram showed development time, stability, elasticity, and valorimeter value of olive oil-added wheat flour decreased, whereas water absorption and stability were similar to control (shortening 4%). Gelatinization temperature and maximum viscosity of wheat flour dough with olive oil decreased more than those of control as revealed by amylogram. Extensogram showed wheat flour area increased, whereas dough volume decreased in olive oil-added wheat flour dough.

Deoxynivalenol (DON)-contaminated barley was treated with 0.1 M $Na_2CO_3$ solution to reduce DON content. DON content of barley was reduced from 2.08 to 0.67 ppm. Bread was made with 10, 20, and 30% DON-reduced barley flour added to white wheat flour. Farinogram showed water absorption and arrival time increased, while stability and mechanical tolerance index decreased when DON-reduced barley flour was added to white wheat flour. Gelatinization temperature, temperature at maximum viscosity, and maximum viscosity increased in amylogram with increasing addition of DON-reduced barley flour. Loaf volume of bread decreased with increasing amount of DON-reduced barley flour, while loaf weight increased. Barley flour pH increased by treatment with$Na_2CO_3$, and pH reduction decreased fermentation rate of yeast. Volume and size of gluten matrix decreased and crumb hardened in bread made with DON-reduced barley flour. Acceptabilities for color and texture were low in bread made with DON-reduced barley flour. Addition of DON-reduced barley flour at 30% reduced overall acceptability, whereas no significant difference in overall acceptability was observed when DON-reduced barley flour was added at 10 and 20%.

This study was carried out to investigate quality characteristics of white breads with cabbage powder(CP) (0, 2.5, 5.0, 7.5 and 10.0%). L-value was significantly decreased by addition of CP, but a and b-values were increased(p<0.05). The degree of pH of dough and bread weight increased with increasing CP concentration, while bread volume, specific volume, and baking loss rate became reduced. The hardness of the breads added with CP was higher than that of the control group. Also, In sensory analysis, the breads with CP showed generally low scores in color, flavor, taste, texture and overall acceptability compared with the control. Taken together, the 2.5%, 5.0% treatment showed similar results with the control group, as compared to other treatments. Addition of CP influenced the color, bread volume and other rheological properties, which is disadvantageous for the quality of white bread. However, compared with the control group, up to 5% CP substitution for flour didn't show significant defferences in sensory test.

Effects of substituting wheat flour with rice flour on bread-making properties were investigated. Rice(Oryza sativa L.) cultivars were 'Goami2(G2)', a functional rice containing higher non-digestible carbohydrates, and 'Chucheongbyeo (CC)', an ordinary Japonica rice. Rice flour was substituted at 10, 20 and 30% in wheat bread formulation, and the composite flour was used for yeast-leavened bread making. Peak and final viscosity of G2 rice flour was significantly lower than that of CC rice flour. Mixograph analysis indicated that replacement of G2 rice flour increased dough water absorption and mixing time compared to wheat flour. But, typical mixograph pattern was not found in the dough from composite flour with CC rice flour. As increasing the amount of rice flour, the G2 rice breads showed a significant decrease in loaf volume, but an increase in bread crumb firmness(g). For the CC rice breads, no significant difference(p<0.05) was observed in loaf volume and crumb firmness, ranging 1012~1050 cc and 433~482g, respectively. The results revealed that Chucheongbyeo is more suitable for bread-making with the composite flour of rice(10~30%) and wheat flour.

The effects of replacement of wheat flour with 10, 20, and 30% chestnut flour on the bread-making properties and quality characteristics of bread were evaluated. Among the physical characteristics of the dough, the development time in the farinogram decreased with increasing amounts of chestnut flour, and the dough stability and durability were reduced. In the amylogram, there was a slight increase in the gelatinization starting temperature when compared to the control flour, but the maximum viscosity gradually decreased in response to increasing amounts of chestnut flour. The expansion ratio did not increase in the dough containing 20 or 30% chestnut flour. Moreover, the loaf volume and specific volume of bread containing 20 and 30% chestnut flour were smaller than those of the control and the 10% treatment. The hardness of bread containing 10% chestnut flour($700g/cm^2$) was lower than that of the other treatments($1413-1,627g/cm^2$). Furthermore, bread containing 10% chestnut flour had denser porous structures than the other treatments. The sensory evaluation tests revealed that the 10% treatment had higher sensory scores for the internal and external qualities of bread than the other treatments.

To make soft and less stale bread, various amounts of gelatinized wheat flour dough were added for making pan bread. In the dough process, higher gelatinized wheat flour dough showed higher consistency and dough development time but a lower dough stability time. Expansion during fermentation represented the highest value upon addition of 10% gelatinized wheat flour dough (GWFD), and this value decreased with increasing amount of gelatinized wheat flour dough. Volume of bread was the highest in the control and lowest in 30% GWFD, and there was no difference between 10% GWFD and 20% GWFD. Moisture contents of bread made with various amounts of gelatinized wheat flour dough increased with increasing gelatinized wheat flour dough amount. Color values of bread made with various gelatinized wheat flour dough were not significantly different. Chewiness, brittleness, and hardness of bread made with control and 10% GWFD showed low values, whereas bread made with 20% GWFD and 30% GWFD showed high values. During storage, chewiness, brittleness, and hardness increased with increasing storage period in whole breads, whereas breads made with 10% GWFD showed the lowest increasing rate. In the sensory strength test, chewy texture increased upon addition of gelatinized wheat flour dough. In the consumer acceptance test, 10% GWFD showed the most overall acceptance. In conclusion, bread made with 10% gelatinized wheat flour dough is desirable for increasing softness and decreasing bread staling.
