The effect of reduced glutathione (GSH) on fresh and pre-proofed frozen dough rheological properties were investigated using dynamic stress rheometry and small scale extensibility with the addition of three levels (80×10-6, 160× 10-6 and 240×10-6 GSH) and six storage times (0 and 1 day, 2, 4, 6 and 8 weeks). Three relaxation times (1, 13 and 26min) after loading the dough in the rheometer were used to determine storage (G’) and loss (G”) moduli. Correlations for G’ (r=0.678 and 0.622 at 0.05, and 10Hz, respectively) and G” (r=0.699, and 0.690 at 0.05, and 10Hz, respectively) were observed with the area under the extension curve at 26 min relaxation time. The addition of GSH to fresh dough reduced G’ (16.4% to 55.9%) and G” (13.7% to 52.2%). Freezing and frozen storage caused increase in G’ and G”. The addition of GSH reduced dough strength indicated by the reduction in maximum resistance to extension (Rmax) and the ratio of maximum resistance to extensibility (Rmax/E). The reduction in Rmax across all relaxation times ranged from 16.2% to 59.4%. An increase in dough extension (E) was observed with 240×10-6 GSH at all frozen storage and rest period times. Addition of GSH caused an increase of liquid phase (30.6% to 35.3%) in fresh dough and frozen dough (10.3% to 20.7%) after one day frozen storage. Negative correlations of water content in the solid phase with dough extensibility and area under the extensibility curve were found (r=-0.594 and-0.563, respectively, ppacity of the dough components changes during frozen storage.

从一万年前生长在Crescent 地区的野生草类首次被驯化,到了解到它们全面的潜在营养价值,谷类谷物对现代人类进展而言仍然是必不可少的。世界上十二种最主要的作物中,有五种谷类 — 大米、小麦、玉米、大麦、高粱,仅此五类就占世界人口消耗热卡的一半以上。科学机构已经开始了解到谷类食品在热量能源之外的重要作用。包含全谷类食品的平衡膳食的重要性不能被过分强调。全谷类食品是食物碳水化合物、微量营养素和植物固醇的来源。一个例子是谷物糊粉层,在许多植物甾醇方面尤其丰富,并有潜在的抗氧化性质。另一个例子是麸皮中的可溶和不可溶的细胞壁成分,它是食物纤维的重要来源。在文献中提供了证实高纤维和全谷物食品在保持身体健康和预防的严重疾病的科学证据。膳食因素被认为可以影响人的体重和人体的防病的总体状况。这个会议将会总结复合糖的关系,全谷类产品和防止某些疾病包括二型糖尿病和冠心病等疾病。
