Changes in Textural Properties of Japanese Tenobe Somen Noodles during Storage

Abstract

Tenobe somen (TS) noodles are traditional Japanese wheat-based noodles that are produced manually using a sophisticated method called tenobe (literally, "hand stretched"). In the tension test, both the tensile strength and extensibility of TS noodles were greater than those of machine-made (MS) noodles. In the biting test, the chewy texture of TS noodles was realized in the analysis of the force-deformation curves of each type of somen noodles. The creep test indicated a clear difference between the external and internal elasticity of TS noodles. The texture of TS noodles appeared to change dramatically during storage in the rainy season. In addition, firm and chewy textures of TS noodles stored for 20 mo were observed. Similar to the results from our previous study, TS noodles exhibited significantly higher dityrosine content than the flour used for their manufacture. However, the increase in the dityrosine content during the manufacturing process was not observed in the case of MS noodles. Although clear textural differences were observed between TS noodles stored for 0 and 20 mo, the dityrosine contents of TS noodles at each stage were not largely different.

Microstructural, Textural, Sensory Properties and Quality of Wheat–Yam Composite Flour Noodles

“…Better elasticity could be due to the co-action of protein and polysaccharides and starch gelatinization. At the same time, it can also be supported by texture profile analysis [30].…”

The Types, Regional Distribution, and Consumption Trend of Chinese Traditional Wheat-Based Foods

“…With the rapid development of the national economy and the continuous improvement of people's living standards, higher requirements have been put forward for the type and quality of wheat products [14][15][16]. e quality of wheat grain is of great significance to flour and other deep-processed wheat products, which directly affects the quality and use of flour [17][18][19].…”

Effect of Thermostable α‐Amylase Addition on Producing the Porous‐Structured Noodles Using Extrusion Treatment

“…As a frequently‐used protein enzyme, α‐amylase can be produced from various sources, such as animals, plants, and microorganisms. It is worth mentioning that no specific safety limit for the acceptable daily intake (ADI) of α‐amylase was recommended by the Joint FAO/WHO Expert Committee on Food Additives (Lii and Chang ; Katagiri and others ). Thus, TαA was applied in many industrial processes, but there is no available information in the literature addressed the effect of TαA on improving the quality of HENs by creating a porous structure.…”
