  • This study was conducted to test the characteristics of dough made with rice flour for preparation of steamed cakes containing rice flour. We used a RVA (Rapid Visco Analyser), farinogram and alveogram to analyze cake flour and mixed powder containing 10, 20, and 30% rice flour for the water activity, texture, and, color changes after different storage periods. We found that rice flour inhibited starch aging, and that gluten free rice flour made the cakes more delicate. However, steamed cakes containing rice flour were harder than wheat cakes during storage. Because the cake was steamed, it had more moisture and was softer than cakes baked in an oven. The steamed cake prepared with rice flour became brighter than the control. The results of the consumer acceptance test and sensory characteristics showed that the steamed cake containing 20% rice flour obtained the highest score, indicating that this is the most appropriate level for making steamed cakes.

  • The aim of this study was to improve rice muffin quality with sorbitol using response surface methodology(RSM). Response surface experimental design was made by central composite design using several independent factors. In preliminary experiment of chlorella rice muffin, rice flour(RF), chlorella(CH) and sorbitol(SO) were chosen as independent factors. Response factor was the overall acceptability obtained from sensory evaluation. The regression model equation could be predicted as $OV=6.70-0.45CH-0.44RF^2-0.81CH^2-0.60SO^2$. The optimal conditions for chlorella rice muffin substituted with sorbitol were determined to be 60.8% of RF, 4.7% of CH and 35.45% of SO. Rice muffin was superior to flour muffin in sensory evaluation using the prediction value derived from RSM. Therefore, the optimum condition of muffin could be developed by RSM.

  • The rutin content of Fagopyrum tataricum is 100-fold higher than that of Fagopyrum esculentum. For the development of a rutin-containing beverage, a suitable method to extract rutin from buckwheat (Fagopyrum tataricum) with high rutin yield was investigated. A roasting temperature range of $310/240^{\circ}C$ (Ed-confirm that this is indeed a range; otherwise perhaps, 'Roasting temperatures ranging from 310 to $240^{\circ}C$ were considered$\ldots$') was considered to be the best as the basic color reference. Rutin content varied according to the roasting time and heating temperature; i.e., it decreased with increasing roasting time and temperature. (Ed- this sentence is unnecessarily complicated and should be simplified to 'Rutin content decreased with increasing roasting time and heating temperature.') The optimal extraction temperature and processing time were obtained as $80^{\circ}C$ and 10 minutes to maximize the rutin concentration in the extract.

  • The perception and attitude of dietitians on processed meats with seasoning were investigated. Questionnaires were distributed to 176 dietitians at school foodservice operations in Kyungnam province. In the survey results, about half (Ed-better to give the exact number of percentage) of the dietitians answered that it is ‘necessary’ to develop processed meats with seasoning. Regarding desired product characteristics, the dietitians were asked about-reduced additive use, good hygienic quality, nutritious and healthy quality, low salt content and adequate supply of nutritional information. Over half of the dietitians-(65.5%) preferred Korean style processed meats with seasoning. The cooking types chosen as new developments for Korean processed meats with seasoning were grilled (36.2%), fried (19.8%), and roasted (18.6%). The dietitians wanted no or only a little increase in the price compared to current commercial products, 1kg (50.6%) size as the package unit and 7 days (45.1%) shelf life under refrigerated or frozen storage.(Ed-confirm the highlighted changes) A majority of the dietitians (64.2%) responded positively to buy the processed meats with seasoning if the products meet their needs.

  • To increase rice consumption and substitute rice flour for wheat flour to make gluten-free bakery products, the physicochemical and pasting properties of rice flours prepared from raw and soaked rices passed through different size screens were investigated. The quality properties of manju dough and preparation of rice manju were also measured. Dry milled flour with soaked rice (DMFSR) were decreased in ash and crude lipid contents compared to dry milled flour with raw rice (DMFRR). Water binding capacity, damaged starch content, and L value of rice flour increased with decreasing particle size, but the b value decreased. Peak, cold, and breakdown viscosities of DMFSR were higher than those of DMFRR by RVA. Hardness of manju dough with DMFSR was lower than that with DMFRR, but that of manju shell exhibited a reverse trend. Sensory difference testing revealed the smoothness of surface, hardness, roughness, and overall quality were significantly different (p<0.05). The smoothness of the surface of manju with DMFRR-200 and all DMFSR were better than that of manju prepared with wheat flour. Hardness showed lower values in DMFRR-200, and all DMFSR as well as wheat flour and roughness decreased with decreasing particle size. Rice manju with wheat flour, DMFRR-200, DMFSR-120, and DMFSR-170 ranked above 5 points and were not significantly different (p<0.05).

  • The anti-diabetic effect of dried-silkworm Dongchunghacho water extracts was investigated in streptozotocin (STZ)-induced diabetic rats. Seven-week-old SD rats were randomly assigned to six groups: normal control (NC) group, diabetic control (DC) group, water extracts of Paecilomyces japonica grown on a dried-silkworm (PJ-DS, 50 mg/kg) group, PJ-DS (250 mg/kg) group, water extracts of Cordyceps militaris grown on a dried-silkworm (CM-DS, 250 mg/kg) group, and water extracts of dried-silkworm (DS, 250 mg/kg) group. These groups were orally provided with sample dissolved in water respectively for four weeks after an injection of STZ (60 mg/kg, ip) followed by identification of diabetic control (DC) group. After four weeks, body weight of all diabetic groups was significantly lower than that of the normal control (NC) group, but among diabetic groups there were no significant differences. Blood glucose levels of the PJ-DS (50 mg/kg), PJ-DS (250 mg/kg), CM-DS (250 mg/kg) and DS (250 mg/kg) groups were reduced compared to the DC group by 3.0 percent, 18.5 percent, 6.9 percent and 13.1 percent, respectively. Concentration of total cholesterol and triglyceride in blood plasma were to some degree decreased in PJ-DS (250 mg/kg) and DS (250 mg/kg) groups compared to the DC group. According to these results dried-silkworm Dongchunghacho water extracts (PJ-DS) boost protection against STZ-induced toxicity.

  • The number of vegans has increased rapidly due to religious and ethical beliefs, environmental concerns, health, etc. Also, as interest in healthy and safe food increases, the demand for organic products or nutrition-enhanced products is increasing. Therefore, this study aimed to investigate the selection attributes and purchasing behavior for protein-fortified and vegan snacks. It is anticipated that the results would find use as basic data for developing protein-fortified snacks for vegans that can meet consumer needs and derive marketing strategies. A survey was conducted on 140 consumers. According to the analysis of their purchase behavior, the number of people who had purchased high-protein snacks and vegan snacks was higher than those who did not have prior experience. The reasons for the purchase of protein fortified snacks included 'meal replacement' at 'offline-convenient store/supermarket'. Vegan snacks were purchased for 'ethical beliefs, health, environment' at 'offline-vegan restaurant, bakery'. Both snacks showed above-normal preferences. However, it is necessary to improve taste and flavor when developing these products as these were the factors that negatively impacted the preferences. The attributes were factorized into the 'showing off factor', 'sensory factor', 'credence factor', and 'functional factor' and the 'sensory factor' was considered the most important.

  • The purpose of this study was to investigate the quality characteristics of bread made with 1%, 3%, 5%, and 7% of Bigeumdo Seomcho powder (Spinacia oleracea L.). The pH of dough and bread decreased as the amount of addition increased; 7% indicated the lowest. The moisture level correlated negatively with the powder addition, but the difference was not statistically meaningful (p<0.05). As the amount of addition was increased, the intensity of color increased but the volume decreased. The brightness and redness of the bread decreased as the amount of addition increased. The volume, specific volume, and baking loss rate correlated negatively with the powder addition. Regarding springiness, cohesiveness, and gumminess, the experiment group was higher than the control group and they lowered as the addition amount increased. The brittleness showed positive correlation with the addition amount. Out of the amino acids of bread, glutamic acid showed the highest value as the amount of addition was increased. Overall, it is possible to produce bakery bread using functional ingredients.

  • In the search for another appealing source of future food to cover the increasing need for nutrients of a growing global population, this study reviewed the potential of insects as human food. This study assessed some common edible insects, but concentrated on mealworms. Insects, especially mealworms, have a similar or higher nutritional value than many conventional food sources. The present study aimed to promote health through the development of blueberry cake by Mealworm Powder (Tenebrio molitor Lavare). The results of Sensory evaluation comparison of Blueberry cake to different levels of mealworm powder. The sensory evaluation showed that sample 3 had the highest color, taste, texture, and overall texture except flavour. Therefore, mealworm blueberry cake made with 60g of mealworm powder showed the best results. The results of analyzing the general components of the Mealworm blueberry cake showed more than two times higher Crude protein and less than half Crude fat compared to control blueberry cake. It is believed that the addition of mealworm powder means that the protein in the cake, a high carbohydrate food, has been strengthened. This is the development of bakery products with both nutritional excellence and symbolism, and it is believed that wheat worm powder is a good food material as a favorite food, not a hateful food, which will improve consumer awareness of edible insects.
