Food and Machinery
Pumpkin powder and wheat flour were used to analyze the farinographic properties, gelatinization characteristics, crystal form and crystallinity of dough, water distribution and rheological characteristics of wheat powder by measuring different addition levels of pumpkin powder. The results showed that the stability time, tolerance index, bandwidth and gelatinization characteristics of the dough were significantly decreased with the increasing of the pumpkin powder content （P<0.01）. The storage modulus and loss modulus first decreased and then increased, while the dough elasticity first increased and then decreased.The content of weakly bound water increased gradually. When the addition amounted to 15%, the crystallinity of starch in dough reached the maximum of 23.9%. In summary, appropriate addition of pumpkin powder could reduce gluten protein concentration, inhibit starch gelatinization characteristics, and improve dough elasticity, thereby could improve farinographic properties and quality characteristics.

Color And Structural Modifications Of Alkaline Extracted Sunflower Protein Concentrates And Isolates Using L-Cysteine And Glutathione, Akira Ishii
Food Science (MS) Theses
Sunflower protein can be extracted at alkaline pH with sulfites or organic solvent de-phenolization of sunflower seed meals if greening is unwanted. This greening is promoted at alkaline pH when chlorogenic acid (CGA) oxidizes and reacts with free amine groups from amino acids, such as lysine. Thiol-containing dough conditioners: L-cysteine hydrochloride and reduced glutathione (GSH) were investigated as an alternative de-greening strategy to de-phenolization. Varying pH from 7 to 11 and concentration of 0.82 to 5.6 mM were randomly assigned by Response Surface Methodology (RSM) to evaluate the combined and additive greening inhibition effect of thiol and extraction pH.

Food and Machinery
19 kinds of selenium-containing rice were collected from 7 towns in Jiangjin District, and the influence of milling on the selenium content of rice was investigated. Significant differences were found in the selenium content in different varieties of brown rice (P<0.05). Yuxiang 203, Jing 1 You Huazhen, Q Xiang You 100 and Jing Liang You 510 had stronger selenium accumulation ability. Under the influence of rice varieties and planting environment, rice bran with different milling rate, selenium content and selenium loss in the milling process were different. The selenium content in rice bran of Yuxiang 203 and Jing1 Youhuazhen was higher, up to 0.82 mg/kg, which could be widely used as selenium-rich by-products produced in the processing process. All the samples showed that higher milling rate could cause higher processing precision and higher loss rate of selenium, and the highest loss rate of selenium was up to 44.39%. During the milling process, the selenium loss of Jing1 Youhuazhen and Jing Liang You 510, planted in Jiasui Town, Q Xiang You 100, and Yuxiang 203 planted in Baisha town and Zhongshan town, was relatively small. After grinding the 80 s, the selenium content in first-grade polished rice could still reach the level of selenium enrichment.
