Novel Antioxidative Activity of Astaxanthin and Its Synergistic Effect with Vitamin E.
Authors: Kogure K Abstract Astaxanthin (Asx) is known to be a potent quencher of singlet oxygen and an efficient scavenger of superoxide anion. However, the scavenging activity of Asx toward the hydroxyl radical was currently unclear because the high lipophilicity of Asx prevents analysis of such activity in water. Liposomes containing Asx (Asx-lipo) were previously shown to be dispersed in water. Analysis of the hydroxyl radical scavenging activity of Asx-lipo demonstrated a dose-dependence in water, with the effect of Asx being more potent than the vitamin E α-tocopherol (α-T).

Effect of Air Nanobubble Water on the Growth and Metabolism of Haematococcus lacustris and Botryococcus braunii.
Authors: Zhu J, Wakisaka M Abstract Miniature air bubbles with a diameter of less than 200 nm were generated by a nanobubble aerator, and nanobubble water (NBW) was eventually obtained using the gas-liquid mixing system with hydrodynamic function. As the air bubbles have long lifetime and high gas solubility in the liquids, NBW is stable in nature and inside contains sufficient dissolved oxygen. At present, there is no report on the use of NBW to replace ordinary water to cultivate microalgae. In this research, effect of NBW on the growth and metabolism of different microalgae, including Haematococcus lacustris and...

Investigation of Pigments in Thai Purple Rice Using Electron Paramagnetic Resonance Imaging and HPLC.
Authors: Nakagawa K, Yooin W, Saenjum C Abstract Paramagnetic species (radicals) related pigments in Thai purple rice were investigated by electron paramagnetic resonance (EPR), X-band (9 GHz) EPR imaging (EPRI), and HPLC. The location and distribution of the paramagnetic species in purple and white rice were determined by EPR and EPRI. EPR primarily detected three paramagnetic species in purple rice, which were identified as organic radicals, Mn2+, and Fe3+ based on the g-values and hyperfine components of the EPR signals. Noninvasive two-dimensional (2D) EPRI revealed that these stable radicals are primarily loca...

Analysis of Chemical Structures of Glucosylceramides from Rice and Other Foodstuffs.
Authors: Sugawara T, Aida K, Duan J, Tomonaga N, Manabe Y, Hirata T Abstract Sphingolipids recently attract more attentions because of their distinctiveness on structures and expected functions. Liquid chromatography-mass spectrometry is one of the most powerful methods for the identification of chemical structures of sphingolipids. Glucosylceramides prepared from various foodstuffs including rice are generally used for functional foods and their structures are quite different from mammals. For structural analysis of glucosylceramides by LC-MS/MS, the typical signals which are characteristic for the sphingoid base ...

Contemporary Global Rice Economies: Structural Changes of Rice Production/Consumption and Trade.
Authors: Ito S Abstract Production technology for rice in the world has been advancing. The supply curve has shifted to the rightward and become flatter over time as well as the scale of economies have been enlarged in many countries. This has led to a great increase in yield per ha. and greater production globally. Accordingly, the rice prices have been becoming more stable and cheaper over time in real term despite of price hike around 2010. Potential of rice production increases for the future is quite large, while demand for table rice has been somewhat stagnant in major producing countries. Because the technol...

Volatile Aroma Compounds in Jasmine Rice as Affected by Degrees of Milling.
Authors: Jinakot I, Jirapakkul W Abstract Jasmine rice (Khao Dawk Mali 105) is popular because of its pleasant unique aroma. Milling is an important step in order to produce various types of edible rice. The distribution of volatile aroma compounds in rice especially, endosperm and bran fractions are different. Hence, the purpose of this study was to determine the volatile aroma compounds of low-milled and high-milled Jasmine rice that affect the aroma quality of cooked rice. The new crop of Jasmine paddy was used in this study. Volatile aroma compounds in raw and cooked rice with two degrees of milling, i.e., low-...

Brown Rice, a Diet Rich in Health Promoting Properties.
Authors: Lee JS, Sreenivasulu N, Hamilton RS, Kohli A Abstract As a staple food crop rice caters to the energy needs of more than 4 billion people around the globe. Since the 1980s, rice breeding focused on breeding for superior grain quality with good texture, taste, palatability and aroma. The recent rise in double burden nutrition challenges suggests that there is a pressing need to focus on incorporating nutritional traits also in rice breeding efforts. The present rice based diet contains nutritional gaps mainly due to the milling process which removes health promoting compounds present in rice bran. Therefore...
