  • 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.

  • Physiological changes that affect nutrient absorption and utilization occur in older adults, and the collection of nutritional information is an important part of examining the nutrition and health issue. A nutritional survey using the 24-hour recall method was performed to identify nutritional quality and leading patterns of food group intake for protein, vitamin C, P and Fe were over 1, whereas those for vitamin A, $B_1$, $B_2$, niacin and Ca were below 1. The MAR(Mean Adequacy Ratio) was relatively low(0.75). The percentage of energy from carbohydrate, protein, and fat was 65.1, 15.6, and 19.5, respectively, thus the quantities of energy source were ideal. The Older subjects revealed poorer nutrition quality than the younger subjects did. The food group intake pattern of the elderly was not diverse, only 9% of them consumed all food groups in a day. These results suggest that nutritional guidelines for older Koreans should focus on the maintenance of adequate energy intake. In addition, selection of foods with high protein and calcium, such as dairy food, should be emphasized, particularly in the older elderly. Nutrition programs should target individuals at risk of not receiving enough nutrients, like the oldest elderly, and persons with lower education.

  • This experiments was designed to evaluated the chemical components and nutrition of Aspergillus fumigatus cells. This dried fungal mycellia was consist of crude protein 48.5%, crude lipid 2.9%, carbohydrate 44.7% and total ash 3.4%, respectively. The major fatty acid of total lipid were 27.9% of linoleic acid, 24.6% of oleic acid, 15.4% of palmitic acid and 10.6% of linolenic aicd. Amino acid analysis indicated that the protein was rich in aspartic acid, glutamic acid, leucine, lysine but poor in cystein, methionine, histidine. The fungal cake of Aspergillus fumigatus, when dried and specially processed, has been found to serve as a source of protein in place of soybean meal in the diet of experimental mice. Animal were fed a control diet first, and an incease in weight proved the formulation to be satisfactory. At the end of a 30-day period, the experimental mice showed increases in weight comparable to those of the control animals. The net protein efficiency ratio for the control diet was 3.42$\pm$0.15 and the fungal protein and succinylated fungal protein with DL-methionine they were 3.12$\pm$0.39 and 2.98$\pm$0.06 respectively. This supports the view that dried and succinylated fungal protein can be substituted as a protein source.

  • Dietary fibers consist mostly of complex carbohydrates such as cellulose, hemicelluloses and pectins, and also included are carbohydrate-based gums or hydrocolloids exampled as alginate, carrageenan, galactomannan xanthan, etc. Due to structural diversity, dietary fibers can be classified by various ways i.e., source, plant function, solubility, charge and topology. Understanding on the plant cell wall structure is of primary importance, since physicochemical properties of dietary fibers are dependent on the existence patterns in the cell wall. Depending on the four distinct observational dimensions, the physical parameters of dietary fibers were discussed in terms of raw sources, bulky & complex plant cell wall materials, individually separated hydrocolloid materials and specifically designed materials. Each existence state possesses the distinct physical parameters governing a variety of physiological properties of dietary fibers.

  • This study was carried out to produce the maltooligosaccharides directly from the culture medium containing high concentration of soluble starch as carbohydrate source by Bacillus cereus IAM 1072. Optimum conditions for the production of maltopentaose and maltooligosaccharides were predicted as 10.62 and 10.92 in C/N ration, 115.74 and 116.51 rpm in agitation speed, 30.19 and 30.9$0^{\circ}C$, respectively. And at these conditions, products of maltopentaose and maltooligosaccharides were 23.23 and 50.33g/L, respectively. From the results of continuous culture for maltopentaose, the productivity increased up to 6.9 times, showing 6.6g/L/hr compared with 0.96g/L/hr batch culture. Maltopentaose showed lower sweetness at 3% concentration representing 1/5 of that sugar. Also, swelling power of maltooligosaccharides was reached to the same point with sugar after fermentation.

  • In the 2020 Dietary Reference Intakes for Koreans, an acceptable macronutrient distribution range (AMDR), similar to the one established in 2015, was determined for carbohydrates. AMDR is the ratio that signifies energy intake from carbohydrates to the total energy intake, and is a reference that indicates a decreasing risk of chronic diseases. The AMDR of carbohydrate was determined to be optimal at 55-65% for all ages above 1 year. For the first time, in the year 2020, the estimated average requirement (EAR) and recommended nutrient intake (RNI) for carbohydrates were established. The EAR was based on the amount of glucose used per day in the brain, and was set at 100 g/day for all ages above 1 year. The RNI was set at 130 g/day, by adding a double coefficient of variation using a 15% coefficient of variation, for all ages above 1 year. In pregnant women, the amount of glucose utilized by the fetus brain was considered additionally, and for lactating women the amount of lactose secreted into maternal milk was additionally taken into consideration. Since the EAR of carbohydrate indicates the minimum amount of glucose required by the brain and is not an appropriate intake amount as an energy source, it is incorrect to compare the carbohydrate intake with the EAR or RNI. To evaluate the nutritional status of carbohydrate, it is appropriate to use the AMDR. Carbohydrate intakes within the AMDR range has the possibility in reducing the risk of chronic diseases. Hence, it is important to consider the quality as well as quantity of carbohydrates consumed.

  • Milk oligosaccharides are the complex mixture of six monosaccharides namely, D-glucose, D-galactose, N-acetyl-glucosamine, N-acetyl-galactosamine, L-fucose, and N-acetyl-neuraminic acid. The mixture is categorized as neutral and acidic classes. Previously, 25 oligosaccharides in bovine milk and 115 oligosaccharides in human milk have been characterized. Because human intestine lacks the enzyme to hydrolyze the oligosaccharide structures, these substances can reach the colon without degradation and are known to have many health beneficial functions. It has been shown that this fraction of carbohydrate can increase the bifidobacterial population in the intestine and colon, resulting in a significant reduction of pathogenic bacteria. The role of milk oligosaccharides as a barrier against pathogens binding to the cell surface has recently been demonstrated. Milk oligosaccharides have the potential to produce immuno-modulation effects. It is also well known that oligosaccharides in milk have a significant influence on intestinal mineral absorption and in the formation of the brain and central nervous system. Due to its structural resemblance, bovine milk is considered to be the most potential source of oligosaccharides to produce the same effect of oligosaccharides present in human milk. This review describes the characteristics and potential health benefits of milk oligosaccharides as well as the prospects of oligosaccharides in bovine milk for use in functional foods.

  • This study was conducted to characterize food waste leachate (FWL) and to compare its characteristics according to generation source: feed supplement- and compost-producing facilities. FWL contained high levels of organic compounds such as carbohydrate, protein and lipid. The moisture content of FWL was among the range of conventional wet anaerobic digestion. FWL was acidic (pH of $4.0{\pm}0.3$) and showed high coefficients of variance for specific parameters: carbohydrate, protein, lipid, ethanol, acetic acid and propionic acid. FWL derived from feed supplement-producing facilities showed slightly lower concentrations of most parameters than FWL derived from compost-producers. However, the difference was not significant at 5% significance level according to analysis of variance.

  • This study was performed to develop and evaluate cookies prepared with various amounts (0 g, 12.5 g, 25 g and 37.5 g) of mealworm powder to serve as not only sports snacks but also for the general population as a new protein source. In the chromaticity of mealworm cookies, lightness and yellowness decreased whereas redness increased with more mealworm powder. The hardness of the mealworm cookies increased as more mealworm powder was added. In sensory evaluation, higher preference was shown with the measure of color, taste, and overall preference for mealworm cookies prepared with 50% mealworm powder (MP2). For the general composition of MP2, the moisture, carbohydrate, crude protein, crude fat and crude ash were higher compared with the control cookie. For the mineral contents of MP2, the contents of Ca (33.44 mg/100 g), P (225.13 mg/100 g), Mg (82.21 mg/100 g), Na (246.22 mg/100 g), and K (503.49 mg/100 g) were higher compared with the control cookie. The essential amino acids (valine, isoleucine, leucine, methionine, threonine, phenylalanine, and histidine) in MP2 were also higher compared with the control cookie. It was concluded that MP2 can be used as a new protein source for not only the maintenance of muscle but also for the prevention of muscle loss in old people.
