Evaluation of the performance of flours from cross- and self-pollinating Canadian common buckwheat (Fagopyrum esculentum Moench) cultivars in soba noodles

Two Canadian cross-pollinating common buckwheat (Fagopyrum esculentum Moench) varieties, Koban and Koto, and two self-pollinating lines, BR01 and BR06, were dehulled and roller milled on a pilot mill to produce three distinct milled products, white flour, dark flour and whole groat flour. The white flours contained mostly starch (79.2–87.2%), whereas the dark flours were rich in proteins (37.1–38.7%), dietary fibre (15.2–22.0%), ash (5.49–5.99%), and fagopyritols (1420–2220 mg/100 g). The buckwheat flours were blended with wheat flour (Canada Western Red Spring straight grade flour) at 60:40 ratios and evaluated for soba noodle properties. Significant differences in milling properties, and in raw noodle colour and texture were detected among cultivars, although the impact of flour type on noodle properties was far greater. The self-pollinating lines exhibited comparable milling and soba noodle properties to Koban. Koto exhibited slightly higher white flour yield and generally firmer noodle texture compared to the other lines. White flours produced the brightest noodles, followed by whole groat and dark flours. Dark flours yielded the thickest cooked noodles with the largest maximum cutting stress and greatest resistance to compression. Noodles prepared with white flour offered the best chewiness, springiness and recovery parameters. Soba noodles prepared with dark flours contained considerably higher amounts of minerals, proteins, dietary fibre, and fagopyritols than noodles prepared with white flour.     

Detection of insect fragments in wheat flour by near-infrared spectroscopy

Insect fragments in commercial wheat flour are a major concern to the milling industry because consumers expect high quality and wholesome products at the retail level. Thus, the US Food and Drug Administration (FDA) has established a defect action level of 75 insect fragments per 50 g of flour. Millers routinely test their wheat flour to comply with this federal requirement and to deliver sound flour to their consumers. The current standard flotation method for detecting fragments in flour is expensive and labor intensive. Therefore, we examined the possible use of a rapid, near-infrared spectroscopy (NIRS) method for detecting insect fragments in wheat flour. We also compared the sensitivity and accuracy of the NIRS method with that of the current standard flotation method. Fragment counts with both techniques were significantly correlated with the actual number of fragments present in flour samples. However, the flotation method was more sensitive than the NIRS method with fragment counts below the FDA defect action level. We were unable to predict whether the number of fragments in a sample exceeded the FDA action level with our NIRS instrumentation. However, we were able to predict accurately whether flour samples contained less than or more than 130 fragments. Although current NIRS instruments are unable to detect insect fragments at the FDA action level, this method should be re-examined in the future because NIRS technology is rapidly improving.     

小麦粉麸星的量化检测与分析

两种制粉方式对紫粒小麦营养功能成分的影响

采用机械分层碾磨和石磨制粉2种加工方式,对"贵紫4号"紫粒小麦加工的面粉和麸皮进行淀粉、粗蛋白、脂肪、粗纤维、维生素、矿物质、氨基酸、总酚、花青素等营养功能成分的对比分析。结果表明,机械分层碾磨和石磨制粉,对面粉和麸皮的营养功能成分影响显著(P<0.05),机械一等粉和机械麸皮的常规营养成分、钙、铁、锌和维生素含量分别高于石磨面粉和石磨麸皮,而石磨面粉的硒含量比机械一等粉高113.90%,石磨制粉的花青素含量比机械制粉高4.90%,说明2种加工方式各有优缺。从氨基酸组成看,"贵紫4号"紫粒小麦的AAS评分高于普通小麦9.70%,且麸皮中的赖氨酸评分大于1(变为非限制性氨基酸),花青素含量达2 904.93 mg/kg,是麸皮入粉进行全麦加工的优质原料。

Effects of ball‐milling on the glass transition of wheat flour constituents

BACKGROUND: Starch and gluten, the major components of wheat flour, greatly influence the structural characteristics of food products made with wheat flour. The effects of ball‐milling on the change in the semicrystalline structure of starch granules to the amorphous state have been reported. However, the effects of ball‐milling of native wheat flour on physicochemical changes in wheat flour constituents have not been elucidated. Therefore in this study the effects of ball‐milling on the glass transition of wheat flour constituents were investigated. RESULTS: Crude gluten, non‐gluten proteins and separated starch were obtained from wheat flour ball‐milled for 0–10 h, and the glass transition temperature (T_g) of these constituents was evaluated. The T_g of all wheat flour constituents decreased with increasing ball‐milling time. Sodium dodecyl sulfate polyacrylamide gel electrophoresis revealed that changes in band position and intensity did not occur for gluten but did occur for non‐gluten proteins. X‐ray diffraction revealed decreased crystallinity and greater plasticisation by water in separated starch as the ball‐milling time was prolonged. CONCLUSION: The results showed that the ball‐milling process decreased the T_g of wheat flour constituents as a function of milling time. The decrease in T_g was probably due to changes in conformation of protein subunits in gluten and depolymerisation of the non‐gluten protein fraction. The information obtained here about the physical alteration of wheat flour constituents may enhance the ability to successfully use ball‐milled wheat flour in food applications.

小麦粉破损淀粉含量的影响因素

分别以软、硬麦为原料,采用在正常生产情况下改变工艺条件并在线取样的方法,取得多组不同样品,样品处理后分别测定破损淀粉含量,研究影响小麦粉淀粉破损的重要工艺因素。研究结果表明：硬麦加工后淀粉破损率高,而软麦则相对较低,硬麦粉的淀粉破损率较软麦粉高出20%左右;面粉越细则淀粉破损率越高;研7磨道数越多,研磨强度越大,淀粉破损越严重;齿辊所造成的淀粉破损程度要比光辊为重,但差距不是很大;撞击机在正常生产时对淀粉破损影响较小,如反复撞击也会使破损淀粉增加,但其影响程度较研磨强度缓和。
