Hence, studies on the allergy have been conducting and have been attracting public attention. Herein, we report studies on research trend of the issue with research papers over the last decade for suggestion of future research direction. Since 2012, studies on allergy of gluten proteins have been dramatically increased based on the number of published papers related to the issue. As results of research activities by country, the Europe accounted for 60% corresponding to the number of papers. Next US (13%), Japan (9%), China (5%), and Korea (2%) came. In Korea, studies on allergy of gluten protein are less studied. In the field of studying of gluten allergy, there are two major technologies as preclinical technology and genome research accounted for 58% and 26%, respectively. In Korea, the study on glutenin proteins which is closely related to wheat allergy is actively performed.

Damaged starch is critical evaluation factor for flour milling related industry because it influences water absorption and color of dough for processing quality and preference of end-use products. The present results revealed that there was significantly high positive correlation between the results of damaged starch analysis by amperometric (SD-matic) and enzymatic (Megazyme assay) methods. Evaluation of damaged starch must be considered as one factor to evaluate properties of starch due to its accuracy and a stable efficiency for the wheat breeding program. Properties of swelling and pasting of dough were important for cooking time and texture. Nevertheless, it was impossible to evaluate starch extracted from flour in the wheat breeding program i.e. small amount of flour or small number of spikes Comparison of results of evaluation of properties of swelling and pasting with starch or flour, the evaluation using flour positively correlated with the other evaluation using starch. In addition, swelling evaluation must be considered to apply for the wheat breeding program because the result of evaluation of swelling property, which possible to evaluate with low efficiency, and the quantity of a sample is highly under positive correlation with paste peak viscosity. In the future, studies using NIR (Near Infrared) analysis must be necessary to evaluate starch properties with grains in early generation lines for improvement of wheat breeding program.","PeriodicalId":448090,"journal":{"name":"Korean Journal of Breeding","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128774704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
