  • The purpose of this study was to determine the optimal mixing ratios for three different concentrations of maltodextrin, dehydration time, and cutting thickness to prepare gingers using molecular press dehydration (MPD) through response surface methodology (RSM) based on the dehydration rate, rehydration rate, and a sensory evaluation. As maltodextrin concentration increased, dehydration rate, rehydration rate, external, flavor, texture, overall acceptability of the gingers tended to be high, and the color tended to be low. As the dehydration time and cutting thickness increased, dehydration rate, rehydration rate and the sensory evaluation of the gingers tended to be high. The maltodextrin concentrations were 70-82%, dehydration time was 5.2-9.2 hr, and cutting thickness levels were 1.0-1.2 mm. The optimal mixing ratios, maltodextrin concentration, dehydration time, and cutting thickness for manufacturing the best quality of gingers using molecular press dehydration were 76%, 7.2 hr, and 1.1 mm, respectively.

  • Indigestible carbohydrates as dietary fiber have attracted interest of consumers due to their several physiological benefits. Recent definitions of dietary fiber have included other indigestible carbohydrates such as resistant starch and resistant maltodextrins, which are natural, colorless, odorless and tasteless low-calorie food ingredients. Unlike some carbohydrates and digestible starches, indigestible starch and maltodextrin resist enzymatic hydrolysis in the upper gastrointestinal tract, resulting in little or no direct glucose absorption. In addition, there is increased microbial fermentation production of short-chain fatty acids in the large intestine. As an emerging functional low-calorie food ingredient, resistant starch and maltodextrin have been shown to have equivalent or superior impacts on human health compared to conventional fiber-enriched food ingredients. In this paper, the definition, strategies to enhance dietary fiber content in foods, some potential health benefits, and applications in food industry for indigestible starch and maltodextrin are summarized and discussed.

  • The effects of drying temperature (55, 60, and $65^{\circ}C$) and addition levels of maltodextrin (MD) (10, 20, and 30%) on the physicochemical properties and nutritional quality of purple sweet potato flour were investigated. MD-added flours had higher $L^*$ values, water soluble index, total phenolic, and anthocyanin contents than untreated flour. However, $a^*$, $b^*$ values, water absorption index, and swelling capacity were dependent on the drying temperature and MD concentration. On the other hand, untreated flour had a higher ascorbic acid content compared to the MD-treated flour. Ascorbic acid contents decreased, whereas anthocyanin content was not significantly different, with increasing drying temperatures. MD was positively correlated with phenolic content, anthocyanin, hue angle, and water soluble index. However, there was no correlation between quality parameters and glass transition temperature. The best quality product was obtained when samples were pretreated with MD before drying, regardless of drying temperature.

  • Attempts were made to fix acetaldehyde on base materials, which were selected from carbohydrates, by freeze drying. More acetaldehyde was fixed, in general, on combined base materials than single base materials, and mannitol+lactose were the best among the combined base materials tested. But the combination of mannitol and maltodextrin appeared to be more economical for the mass production. Loss of acetaldehyde during freeze drying was decreased as the concentration of the combined base material was increased, and it reached minimum at 40% of the base material. As dryer chamber pressure was reduced, loss of acetaldehyde during drying was decreased.

  • In this study, gluten-free noodles were developed and the physicochemical quality of gluten-free noodles added with nondigestible maltodextrin (NMD) was also investigated. The gluten-free noodles were prepared by addition of 0, 5, 7, and 9% NMD of total ingredients except water. Inhibition activities for ${alpha}$-amylase and ${alpha}$-glucosidase according to the addition amounts of NMD were evaluated. As a result, activities of carbohydrate-digestive enzymes decreased with an increase of the added NMD amounts. Water binding capacity and solubility of raw noodles increased upon NMD addition. Swelling power also increased as temperature rose. L value of raw noodles decreased with the addition of NMD, but b value increased. Texture profile analysis of cooked noodles showed reduction of hardness, springiness, and chewiness of noodles with NMD. On the other hand, tensile strength of cooked noodles containing up to 7% NMD was not significantly different from that of noodle without NMD. In the sensory evaluation, elasticity of noodles with 9% NMD was lower than that of other noodles, whereas other characteristics of noodles were not significantly different among noodles. Therefore, it was confirmed that the addition of 5~7% NMD had little effect on the sensory quality of noodles.

  • The main purpose of this study is to examine the different physicochemical properties of spray-dried products. The carrier agents and powders after the spray-drying process were analyzed for encapsulation yield, moisture content, color parameters, total polyphenol content (TPC), antioxidant capacity (AC), bulk density, flowability, wettability, hygroscopicity, water solubility index (WSI), particle size and microstructure. The spray-drying process was carried out with different carrier agents including maltodextrin (MD) and the combination of maltodextrin and gum arabic (MD-GA) with MA/GA ratio of 70/30, dried at the inlet/outlet air temperature of 160 ℃/70 ℃, 4 bar, airflow rate of 70 ㎥·h-1 and feed flow rate of 750 mL·h-1. The results showed that the different carrier agents have significant influences on the physicochemical properties of the powder produced by the spray-drying method. In there, while the values of recovery efficiency and flowability of spray-dried products from MD are higher than those of spray-dried products from MD-GA combination, the opposite is true for the values of TPC, AC, bulk density and wettability, whereas hygroscopicity and WSI values are equally represented in both products.

  • The aim of this study was to develop a new salting condition that included added maltodextrin (MD) and grape seed extract (GSE) to ensure the microbiological safety and quality of salted shredded Korean cabbage. Response surface methodology (RSM) was used to analyze the effects of four independent variables (NaCl concentration, salting duration, MD concentration, and GSE concentration). The following response variables were evaluated: reduction in total aerobic bacteria, yeast, and mold counts; weight loss and salt content; and taste, texture, and overall acceptability of salted shredded Korean cabbage. The optimal salting conditions include a combination of 10.09~10.32% NaCl, 9.45~10.00% MD, and 234~300 ppm GSE in a ternary salting solution and a salting duration of 5.68~5.94 hr. This optimal combination reduced total aerobic bacterial and yeast/molds counts by 3.33 and 1.45 log CFU/g, respectively, while maintaining high sensory scores for taste, texture, and overall acceptability of the salted shredded Korean cabbage. In addition, the optimal conditions yielded more acceptable weight loss and salt content characteristics. The results suggest that use of the optimized combination of salting conditions can improve the microbiological safety and quality of salted shredded Korean cabbage used for commercial kimchi production.

  • The functional characteristics of a ${\beta}$-cyclodextrin glucanotransferase (CGTase) excreted from alkalophilic Bacillus sp. BL-31 that is highly specific for the intermolecular transglycosylation of bioflavonoids were investigated. The new ${\beta}$-CGTase showed high specificities for glycosyl acceptor bioflavonoids, including naringin, rutin, and hesperidin, and especially naringin. The transglycosylation of naringin into glycosyl naringin was then carried out under the conditions of 80 units of CGTase per gram of maltodextrin, 5 g/l of naringin, 25 g/l of maltodextrin, and 1 mM $Mn^{2+}$ ion at $40^{\circ}C$ for 6 h, resulting in a high conversion yield of 92.1%.

  • Plum (Prunus salicina L.) slices were dehydrated with red algae extract (RAE) at a concentration of 30% (w/w), and the dried samples were compared with maltodextrin (MD)-treated and hot-air dried samples in terms of physicochemical properties such as rehydration ratio, ascorbic acid, microstructure, and color. The rehydration ratios and colors of RAE-treated plum slices were better than those of MD-treated and hot-air dried samples. The ascorbic acid contents of RAE-treated samples were higher and their microstructures were finer than those of MD-treated or hot-air dried samples. These results suggest that plum slices can be dehydrated with RAE without loss of quality.
