This study investigated the quality characteristics of noodles containing roasted Liriopis tuber. Roasted Liriopis tuber powder (LTP) was added in different amounts based on wheat flour (1%, 3%, 5%, 7% and 9%). Cooked noodles containing LTP exhibited significantly lower values for weight, volume, and water absorption; in contrast, higher values were exhibited for turbidity. The Hunter L value (for lightness) of uncooked and cooked noodles decreased but the a value (for redness) and b value (for yellowness) increased with the addition of Liriopis tuber. Textural properties (springiness, cohesiveness, chewiness, and brittleness) measured with a texture analyzer significantly decreased with the addition of Liriopis tuber. From the sensory evaluation results, noodle containing 7% Liriopis tuber was considered the best. To improve the quality of noodle containing 7% LTP, activated gluten was added at different percentages of flour (1%, 2%, 3%, 4% and 5%). Cooked noodles containing activated gluten exhibited significantly higher values for weight, volume, and water absorption; in contrast, lower values for turbidity were exhibited. In addition, the textural properties significantly increased with the addition of activated gluten. From the sensory evaluation results, noodle containing 3% activated gluten was considered the best. In conclusion, noodle with 7% LTP and 3% activated gluten exhibited the most desirable qualities.

Wheat gluten is an increasingly common ingredient in poultry diets but its impact on the small intestine in chicken is not fully understood. This study aimed to identify effects of high-gluten diets on chicken small intestines and the variation of their associated transcriptional responses by age. A total of 120 broilers (Ross Strain) were used to perform two animal experiments consisting of two gluten inclusion levels (0% or 25%) by bird's age (1 week or 4 weeks). Transcriptomics and histochemical techniques were employed to study the effect of gluten on their duodenal mucosa using randomly selected 12 broilers (3 chicks per group). A reduction in feed intake and body weight gain was found in the broilers fed a high-gluten containing diet at both ages. Histochemical photomicrographs showed a reduced villus height to crypt depth ratio in the duodenum of gluten-fed broilers at 1 week. We found mainly a significant effect on the gene expression of duodenal mucosa in gluten-fed broilers at 1 week (289 differentially expressed genes [DEGs]). Pathway analyses revealed that the significant DEGs were mainly involved in ribosome, oxidative phosphorylation, and peroxisome proliferator-activated receptor (PPAR) signaling pathways. These pathways are involved in ribosome protein biogenesis, oxidative phosphorylation and fatty acid metabolism, respectively. Our results suggest a pattern of differential gene expression in these pathways that can be linked to chronic inflammation, suppression of cell proliferation, cell cycle arrest and apoptosis. And via such a mode of action, high-gluten inclusion levels in poultry diets could lead to the observed retardation of villi development in the duodenal mucosa of young broiler chicken.

To lower the calories of buckwheat noodle, which is good for reducing obesity and for Preventing adult disease, glucomannan and flour containing resistant starch(RS) were used during the noodle making Process. Compared with raw noodle, this buckwheat raw noodle had $30\%$ fewer calories. This low caloric buckwheat noodle was coated with olive oil which is reputed as well-being food to prevent soddening to make instant type buckwheat noodle. Its shelf-life was extended to 90 days under normal temperature($35^{\circ}C$I). Among four noodle samples with different combinations of raw materials, the best was made of flour with RS formula flour, buckwheat flour, glucomannan, activated gluten, and emulsifying agent. The one without salt had better quality. Among 6 kinds of packing materials, OPP/Al/PE composite level film demonstrated the best quality packing materials.

The objective of this study was to investigate the essential fatty acids requirement and its optimal level in dietary for young of tiger puffer. The young puffer fish used in feeding trial were average body weight 3.45g. Fish were randomly divided into 11 groups containing 30 fish each in 200 ${\ell}$ tank and reared for 8 weeks at ambient temperature. In basal diets, defatted squid meal, casein-Na and activated gluten were used as the dietary protein source, dextrin and ${\alpha}$-starch (gelatinized starch) as the digestible carbohydrate source and beef tallow as the lipid source. Five fatty acids added to diet were linoleic acid (LNA), linolenic acid (LNA), eicosapentaenoic acid (EPA) ,docos-ahexaenoic acid (DHA) and n-3 HUFA. Among that, the supplement of LA and LNA were $1\%$ of total composition of diet, respectively, and EPA, DHA and n-3 HUFA ranged from $0.3\~1\%$ level. Growth and feed efficiency were measured to the interval of 2 weeks, and analyzed fatty acids composition of diet and liver by GCL. As a result of 8 weeks experiment, predominant growth were shown in $0.5\~1\%$ n-3 HUFA and $0.5\%$ DHA than others (P<0.05). In comparison of efficiency among EPA, DHA and n-3 HUFA groups, the most results were revealed in n-3 HUFA and the least in EPA. The adding effect was shown in EPA by increasing the fatty acids content from 0.5 to $1\%$ in diet. However, sudden decline and steady state in growth were observed in $1\%$ DHA and $1\%$ n-3 HUFA, respectively. The feeding efficiency and protein efficiency ratio were high in n-3 HUFA groups and $0.5\%$ DHA. Consequently, it is assumed that young puffer requires n-3 HUEA both EPA and DHA as essential fatty acids. The optimal content in diets are about $0.5\%$ of HUFA or DHA.
