Hypochlorite oxidation of field pea starch and its suitability for noodle making using an extrusion cooker

The effect of hypochlorite oxidation on the Brabendar pasting properties of field pea starch and the suitability of native and oxidized starch for noodle making by extrusion cooking were investigated. Field pea starch was oxidized with sodium hypochlorite at a level of active chlorine ranging from 0.89 to 3.28% (starch db). The degree of oxidation was determined and expressed in terms of percentage of carboxyl and carbonyl groups, which ranged from 0.02 to 0.38% and 0.06 to 0.19%, respectively. Starch recovery and peak viscosity, hot paste viscosity, cool paste viscosity, and setback of oxidized starches decreased with increasing degree of oxidation. The cooking quality attributes of noodles prepared from native field pea starches were acceptable but were negatively influenced by hypochlorite oxidation. Substitution of potato starch (40%, db) for field pea starch yielded more glossy noodles with better cooking quality. It was also observed that Brabendar pasting properties had high correlations with noodle quality characteristics.     

Characteristics of Noodle Prepared from Orange-fleshed Sweet Potato,and Domestic Wheat Flour

Noodle characteristics prepared from both 100% of domestic and imported wheat flour (as a control) and blended with 40% of orange-fleshed sweet potato paste were studied. The domestic wheat flour had higher protein content (13.8%), compare to imported wheat flour (11.7%), thus giving the highest protein content (18.86%) in noodle prepared from 100% domestic wheat flour. However its noodle colour was disliked due to a lower whiteness level compared to imported wheat flour. Blended 60% of domestic wheat flour with 40% of sweet potato paste could improve the noodle colour acceptance. The noodles prepared from both 100% wheat flours and blended with 40% sweet potato paste had met the national standard quality for moisture and protein content. This suggests that sweet potato paste is promising for noodle ingredients as a wheat flour substitute.     

豌豆分离蛋白对小麦粉面团特性及挂面品质的影响

研究豌豆分离蛋白(PPI)添加量对小麦粉面团蛋白质组成、粉质特性、拉伸特性和对挂面断裂强度、烹煮特性及感官品质的影响。结果表明:添加PPI后面团中23.8~100.1 ku的蛋白条带明显加深;当添加量为9.0%时,面团吸水率提高8.0%,稳定时间延长36.6%,拉伸阻力提高83.2%,拉伸比增大176.2%,说明PPI的添加能够提高面团的筋力;PPI添加量达到7.0%时,挂面最佳烹煮时间降低11.8%,生挂面断裂强度提高34.0%,同时熟挂面的硬度、胶着性和咀嚼度有不同程度的提高。感官品评表明,添加3.0%~7.0%PPI制备的挂面与普通挂面无显著差异。     

Effect of heat treatment and salt addition on the physicochemical properties and quality of fresh noodles

Heat treatment and salt addition on the physicochemical properties and quality of fresh noodles were investigated. The water activity was decreased, while the bound water content was increased after heat treatment, and this effect was dependent on the treated intensity and salt concentration, which extended the shelf life of noodles. The content of SDS-soluble protein was decreased after heat treatment, and this effect was dependent on the treated intensity. However, 3% salt concentration can reduce the aggregation of SDS-soluble protein. The paste viscosities were reduced, whereas the gelatinisation temperatures increased after heat treatment, and the variation was increased with increasing salt concentration. The hardness and chewiness of cooked noodles were increased after heat treatment, but adding salt reduced this effect. Results showed the quality of heat-treated noodles can be precisely controlled by the addition of salt, and the optimal treatment condition was 98 °C and 2% salt concentration.     

大麦粉改善生鲜湿面的品质特性

通过添加不同比例的大麦粉(10%~60%)配成大麦-小麦混合粉,研究大麦-小麦混合粉的糊化特性和面团的流变学特性以及生鲜湿面的色泽、蒸煮损失率、断条率、质构特性。结果表明,当大麦粉添加量30%时混合粉的峰值黏度、崩解值、最终黏度和回生值升高幅度最大,升幅分别为50 cP、42 cP、39.66 cP、31.67 cP;生鲜湿面的硬度、内聚性和回复性分别升高了23.77%、6.85%、8.64%;拉断力和拉伸距离分别降低了13.80%、70.22%;在大麦粉添加量40%时,生鲜湿面的蒸煮损失率和断条率分别提高了37.36%、10.83%。随大麦粉的添加比例升高,面团弹性模量、黏性模量增大,tanδ值降低;面片的亮度显著下降。综合考虑,大麦全粉添加比例小于30%时,混合粉仍具有较好的加工特性,生鲜湿面的整体品质可被接受,更高比例的加入会导致生鲜湿面蒸煮损失率和硬度显著升高。
