  • Neillieae was traditionally recognized as a small tribe in Rosaceae, which consists of Neillia, Stephanandra, and Physocarpus. Recently, Stephanandra was merged into Neillia based on molecular phylogenetic analyses, meaning that Neillieae now contains Neillia and Physocarpus. The genus Neillia is distinguished from Physocarpus by ovate to lanceolate leaves with acuminate to caudate apices, racemose or paniculate inflorescences, and a unicarpellate (rarely bicarpellate) gynoecium. Plants of Neillia are distributed from the Himalayas across China and Korea to Japan in the east, and south to Indonesia. This study provides a taxonomic treatment of Neillia based on a morphological examination of herbarium specimens, including types, and field observations, as the second part of the taxonomic revision of the tribe Neillieae. A summary of the phylogeny of Neillia, keys to the species, nomenclatural reviews, descriptions, distribution maps, and lists of specimens examined are provided. Twelve species with ten varieties are recognized in Neillia. A lectotype was designated here for the following species: N. sinensis f. glanduligera and N. thyrsiflora.

  • Quality characteristics of conventional and whey noodles were investigated by studying the textural properties. cooking properties, and sensory characteristics. The whey noodles were prepared by mixing whey powder with the wheat flour before noodle production, with the mixture ratio ranging between 1 and 7% in volume. The results are summarized as follows : the addition of whey powder noticeably improved the textural characteristics of the cooked noodles, i.e. hardness, gumminess, and chewiness. The best results were obtained using the following percentage of whey in the mixture: the hardness with 1% added, the gumminess and chewiness with 3% added, and the elasticity with a 7% addiction. The tension force also increased with addition of whey powder, The highest tension force was obtained when 3% of the whey was mixed. While the cooking water of the general noodles displayed a light reddish tint, the cooking water of the whey noodles had a yellow-greenish tint. The cooking water of the whey noodles was more turbid than that of the conventional noodles. The whey noodles increased in volume more than the conventional noodles. after cooking. There was no difference in weight increase and water absorption rates between both types of noodles. More favorable results were shown for appearance, color, texture, and sensory acceptability in the whey noodle than in the conventional noodles.

  • Cysteine, a thiol group-containing reducing agent which is known to relax the strain and increase the viscosity of dough, was added to Korean and imported wheat flour noodles to investigate the effect on the properties of raw, dried, and cooked noodles and to determine the optimum cooking time and amount to improve the color of noodles. Addition of cysteine up to 1% of flour (8.25 mmole/100 g flour) was not effective in increasing the brightness of raw and dried noodles and in changing the water activity of dried noodle. However, cysteine improved the brightness of cooked noodle made of both Korean and imported wheat flours. Also, there were notable differences in cooking and sensory properties of cysteine-added cooked noodles such as less firm and stickier texture due to the extraction of organic compounds into broth. When the noodles were cooked for their optimum cooking time, no difference was noticed in the texture and overall preference regardless of the addition of cysteine. Overall, the addition of 1 % cysteine increased the brightness of cooked noodles and reduced the cooking time.

  • The purpose of this study was to investigate the physicochemical and sensory characteristics of A. scaber noodle added with A. scaber extract solution or powder. The weight of cooked noodle and noodle added with A. scaber extract solution was higher than those of the non-added noodle (control) and dried A. scaber powder added noodle. As the amount of A. scaber extract solution or powder was increased, the water absorption rate of noodle was decreased. As the amount of A. scaber solution or powder was increased, the 'L' values of noodles were decreased. Since the 'a' values of all noodles were negative and the 'b' values of all noodles were positive, the color of all noodles were determined to be yellow green. The pH of noodles were 5 to 6 in control noodles and noodles with A. scaber powder. The pH of noodle added A. scaber extract solution was lower than those of others. As amount of A. scaber extract solution or powder was increased, the elasticity of all noodles was decreased. The chewiness of noodles was the highest in noodle added A. scaber extract powder. The quality of noodle added A. scaber extract solution was the excellent among the all other noodles. This result showed that, the quality characteristics and palatability of noodle added A. scaber extract solution or powder was higher than those of control noodle.

  • To address the limitations of manufacturing noodle products using rice, brown rice noodles were created by the fermentation of brown rice containing several nutrients and the quality of these noodles were evaluated. White rice noodles, fermented white rice noodles, brown rice noodles, and fermented brown rice noodles were developed using white rice and brown rice, respectively. We found that the content of crude proteins present in the noodles during the fermentation process increased and the content of crude fat and carbohydrates in the noodles was reduced. In addition, the water content of brown rice noodles was twofold higher than that of white rice, although under fermentation conditions, the water content of brown rice noodles decreased slightly. A slight change of chromaticity was observed during the fermentation process. In cooking, the weight and volume of the noodles increased, with the change being lowest in noodles based on white rice. White rice-based noodles exhibited significantly higher turbidity in the cooked noodle soup, while other noodle products showed relatively constant turbidity. Most of the products showed a decreased texture, becoming soft with cooking; however, the elasticity of the cooked products increased. Our results suggest that the disadvantages of producing rice noodles can be overcome by the development of fermented brown rice noodles containing a variety of nutritional components. This would potentially develop a market for rice-based manufactured foods that appeal to modern preferences.

  • In order to provide fundamental data on development of rice noodles, the quality characteristics of 10 kinds of commercial rice noodles were evaluated. Rice noodles were categorized into 3 groups for examination: 100% rice noodles with different shapes; round shape noodles with different rice contents; and noodles with different rice contents but smilar cooking method. Cooking properties, texture measurement, and sensory characteristics were evaluated. Frozen rice noodles and instant type of noodles made from composite flour of rice and wheat flour exhibited higher scores in overall acceptance. As for the form of noodle, round-shaped noodles seemed to be preferred in comparison to flat-shaped noodles. Generally, noodles with high texture scores of cohesiveness, adhesiveness, chewiness, resilience but not high score of hardness having smooth surface were preferred affecting overall acceptance scores. It appears that cooking methods and cooking time recommended by manufactures, noodle thickness and shape, packaging types such as frozen, refrigerated, and dried noodles were more influential than rice contents in aspects to the quality characteristics of the commercial rice noodle products in this study.

  • The tribe Neillieae, a small group of about 18 species in the Rosaceae, comprises three taxonomically difficult genera, Neillia, Physocarpus, and Stephanandra. The tribe, characterized by lobed leaves with persistent or deciduous stipules and ovoid, shiny seeds with copious endosperm, is strongly supported as a monophyletic group by a variety of lines of molecular evidence. Due to the high amount of morphological variation across the three genera and the species in tribe Neillieae, conflicting classification schemes and numerous species have been proposed over the past three centuries. However, no comprehensive systematic study of the group, including all species across their geographic ranges, has ever been undertaken. As part of a taxonomic revision of tribe Neillieae, a revision of Physocarpus based on the morphological examination of herbarium specimens, including types, and field observation is presented. Artificial keys, comprehensive nomenclatural treatments, descriptions, distribution maps, and lists of specimens examined are provided. Six species in Physocarpus are recognized. A lectotype is here designated for the following species: Opulaster pubescens, Opulaster ramaleyi, Spiraea opulifolia var. parvifolia, Spiraea opulifolia var. tomentella, Physocarpus michiganensis, and Physocarpus missouriensis.

  • This study was conducted to investigate the effects of substituting whole barley flours on quality characteristics of noodles. Noodles were made with composite flour containing 20% whole barley flour of various hullless barley cultivars and the quality characteristics, ${\beta}$-glucan content and antioxidant characteristics were investigated. In amylogram characteristics, the initial pasting temperature and peak viscosity were increased, and setback was decreased in complex flour. Noodles containing barley flour had low lightness, yellowness and high redness compare to wheat noodle. Water absorption of cooked noodles was lower than wheat noodle. The value of swelling index was high in noodles containing non-waxy barley flour and low in noodles containing waxy barley flour. Hardness and gumminess of noodles were lower than wheat noodle. Noodles containing non-waxy barley had higher hardness, cohesiveness and gumminess than noodles containing waxy barley flour. Dahan, non-waxy barley cultivar showed similar characteristics with the wheat noodle. ${\beta}$-Glucan content and antioxidant activity were increased with adding barley flour. Cooked noodle had slightly high ${\beta}$-glucan content, low starch content and low antioxidant activity compared to value of uncooked noodle.
