  • Bread-baking properies of naked barley flour and naked barley-wheat flour blends were investigated, and changes of loaf volume of naked barley bread prepared by straight method and by lactic acid method were observed. Specific loaf volume of naked barley flour bread made by straight method was only 1.11 ml/g bread, while that of barley bread made by lactic acid method was more than 1.50 ml/g bread. No significant increase of loaf volume was noted in mixed naked barley-wheat bread. The increase of loaf volume of barley bread appeared to be due to total titratable acidity of barley dough. Loaf volume of what bread made by lactic acid method decreased sharply as the total titratable acidity of wheat flour dough increased.

  • The effects of defatted soy flour on the physicochemical characteristics of dough and bread making properties were studied. Defatted soy flour is added to wheat flour for bread-making in order to maximize the use of isoflavones in the soybean. Different particle sizes of both defatted soy flour and wheat flour were prepared by grinding and sievingwith meshes. In the mixograph test, the addition of defatted soy flour to wheat flour increased the requirement for water and decreased the dough development time. Water absorption rates were also investigated to determine the optimum quantity of water for good dough. As the level of defatted soy flour mixed with wheat flour increased, the sedimentation and P.K. values decreased. In comparison with control, the bread made with defatted soy flour especially had a lower specific loaf volume. Specific loaf volume of wheat flour-defatted soy flour bread prepared (Ed- this is an incomplete sentence, it's only a subject clause, and I don't how what you intend to state). In terms of the staling rate and hardness of the wheat flour-defatted soy flour bread, the increased defatted soy flour had a faster staling rate during storage at 5? than at 25? for 5days. From the result of sensory evaluation, wheat flour-defatted soy flour breads containing up to $4\%$ defatted soy flour were rated as being of high quality.

  • To investigate possible effects of buckwheat on blood glucose level and blood pressure, Sprague-Dawley rats were divided into two groups and fed either AIN-76 diet or modified AIN-76 diet with buckwheat flour for 4 weeks. At the end of experiment, determinations of blood pressure and blood glucose level(glucose tolerance test) were performed. In order to determine insulin levels in both fasted and glucose loaded serum, the animals in both groups were subdivided into two groups. Blood pressure was slightly decreased in the group fed buckwheat( 6mmHg) but not significantly. Glucose tolerance curve of the animal fed buckwheat flour showed clearly different pattern from that of the control group with decreasing tendency. Mobilization of serum insulin was 1.5 times faster in buckwheat group than in control group 1 hour after glucose loading. Further research is needed to find what substance(s) in buckwheat do this role.

  • The purpose of this study was to investigate the dietary intakes of preschool children in rural areas and to develop programs of nutrition education, offering the mothers an appropriate advice for the improvement of the dietary practices corresponding to the modernization of the agriculture. The daily food intakes of 118 preschool children, randomly selected from the farm household, were studied by means of three-day records during summer season of 1972. The results showed that the dietary intakes of food groups such as meats and fishes, beans and the products, milks and small fishes, fruits, fats and oils were below 50 per cent of the recommended level-especially in that of milk. Therefore, the diet was generally below the recommended dietary allowances for protein with good quality, fat, calcium, vitamin A, thiamine, reboflavin and ascorbic acid. The dietary data revealed that most of preschool children in rural areas consumed rice and barley, almost every day. Other foods eaten less frequently were soybean paste, gimchi, potatoes, flour, and summer squash. The use of cereals should be curtailed some what and the use of milks, fishes, poultry, meats and protein extenders should be increased.

  • Quality characteristics of dough and noodles prepared from Korean wheat flours (Gru and Tapdong) were evaluated by substituting foreign wheat flours and starch in the formula. Korean wheat flours showed greater water absorption and weakness as well as protein and ash contents, but lower stability than the foreign wheat (control) By increasing substituted foreign wheat flours, water absorption of domestic Gru and Tapdong decreased. Dough development time decreased for Tapdong by substituting up to 30% with foreign wheat flours. When imported wheat flours added in Gru and Tapdong, weakness of dough was decreased. Adhesiveness of dough was increased in all samples according to water adding, and Gru particulary showed the most high adhesiveness at 65% water and 10~20% replacement. From the mechanical texture test, Tapdong noodles were increased in cutting force by increasing amounts of imported wheat but decreased in extension distance. However, Cru noodles showed the opposite tendency. Hardness, adhesiveness, and chewiness of noodles were increased in all samples by increasing amounts of substitution with imported starch. As a result of cooked noodles test, Korean wheat noodles showed relatively lower values in cutting force and extension distance than in those of the control Studies of noodle-related characteristics of Korean wheat flours indicated that domestic soft wheat such as Gru might have high quality above the foreign wheat in noodle preparation by adding flours containing high amylose or low gluten.

  • The effect of oxidants, gluten and gums on breadmaking quality of wheat-purple sweet potato(Ipomoea batatas) composite flour were studied. Alveograph tests of doughs showed that all additives increased the P, L and W values. Of these additives, L-Ascorbic acid, gluten, carboxy methyl cellulose have a significant effect on alveogram indexes. SEM showed that the dough added with additives changed some what in appearance when compared with the control. When oxidants was added, the doughs discontinuous gluten film were observed. No significant differences ,were evident in bread crumb color among the additives. And textural characteristics of bread crumb were influened by adding additives. Breads containing additives showed an increase in max weight, strength and hardness and a decrease in springness and cohesiveness. Average enthalpy values for all bread crumb after 7days increased with storage time. However, addition of additives decrease the rate of staling slightly more than that of the control. Addition of L-Ascorbic acid, L-Cystine, carboxy methyl cellulose and hydroxy propyl methyl cellulose increased the loaf volume significantly, and with except potassium bromate bread scores were acceptable.

  • This paper is intended to study what kinds of the vegetables are mentioned in the Bible and how they were used in those days. While one hundred and twenty-eight different plants are mentioned in the Bible, there are today 2,384 plant species in modem Israel, most of which have been introduced in recent centuries. These plants obviously did not exist there in biblical times and were only recently introduced from Australia and South America, respectively. This article will study only the vegetables mentioned in the Bible and known to have existed in the old and new testament times. Since the first book devoted exclusively to biblical botany was that of Levinus Lemmens in 1566, the modem systematic study of biblical plants, began with F. Hasselquist, a student of Linnaeus, the founder of modem botany. In 1928, Immanuel Loew approached the subject differently, reviewing all known data pertaining to biblical plants. His work not only discussed biblical plants, but also plants in later Jewish literature, particularly the Talmud. The British scholar G. E. Post provided a broad field study of modem plants in Palestine, Syria, Lebanon, and Jordan. More recent major treatments of the subject include those of A. and H. Moldenke (1952), M. Zohary (1982), N. Hareuveni (1984), and Y. J. Choi(1996). Today, articles on specific biblical plants listed in the Bible can be found in any number of encyclopedias. This study attempts to provide a synthesis of the work of a number of scholars who studied the vegetables and plants mentioned in the Bible. As a preliminary study on the culture of food in the biblical period, this study has focused on the identity and features of the vegetables of the Bible. In only a limited number of instances, because of the paucity of the informations and the broad and generic descriptions of the plants, we can't be certain about the identification of the vegetables named in the Bible. In many instances the traditions established by the Greek, Aramaic, and English translations are helpful, although sometimes they are misleading. This paper subdivides the vegetables into broad areas, the general vegetables and the flavoring herbs. Vegetables formed very important part of the diet in the biblical times. Two main types were used: those whose nutritious seeds could be easily stored and those which were eaten freshly gathered from gardens. Pulse seeds provided a useful source of vegetable protein, while fresh green vegetables were vitamin rich. Pulses could be eaten boiled, or their dried seeds could be ground up into flour and then made into nutritious soups. Fresh vegetables were eaten either raw or lightly cooked, usually by boiling in water. The general vegetables in the Bible are herbs(garden rocket), cucumber(snake cucumber), watermelon, leeks, chicory, and onions. Also the flavoring herbs in the Bible are rue, dill, cummin, black cummin, frankincense, cinnamon, cassia, myrrh, black mustard, coriander, mint, saffron, ginger grass, syrian hyssop, aloes(eagle wood), manna which have the flavor, aroma, and medical values.
