红酸汤作为一种广受食客喜爱的酸味调味品,其烹调过程中必然会添加蔬菜,但烹调蔬菜对红酸汤中全反式番茄红素含量的影响目前还未见太多研究,因此文章拟对此进行研究。实验表明少量蔬菜(2.红酸汤添加量)烹调6min对红酸汤中全反式番茄红素含量无明显影响(P>0.05)。当白萝卜添加量达到12.(6倍红酸汤添加量)或洋葱添加量达到8g(4倍红酸汤添加量)时,烹调6min红酸汤中全反式番茄红素含量显著降低(P0.05)。实验所选的3种蔬菜中添加洋葱(4倍及以上红酸汤的量)或白萝卜(6倍红酸汤添加量)烹调6min的红酸汤可能全反式番茄红素向顺式番茄红素转化更多,对健康更有利。

以聚砜为基础材料,基于后磺化法构筑一种具有较长侧链的交联型聚砜阴离子交换膜,并通过FT-IR对其结构进行表征,研究了阴离子交换膜的吸水率、质子传导率和尺寸稳定性等性能与温度之间的变化关系。结果表明,由于亲水季铵基距离主链较远,强化了阴离子交换膜的相分离结构,同时形成一种三维网状结构,使得所制备的聚砜阴离子交换膜在高质子传导率下仍能保持很好的尺寸稳定性和耐碱性,其中IEC为1.56 mmol/g的CPS-HN-3膜在室温和85℃的吸水率达到了39.6%和61.6%,高于商业化Nafion115和Nafion117膜,但是吸水溶胀性仅为5.1%和11.7%,氢氧根离子传导率达到了38 mS/cm和89 mS/cm,该膜在强碱中浸泡600 h的传导率保留量达到了83.9%。

This study was conducted to verify the inheritance of certain characters of rapeseed including erucic acid, glucosinolate and oleic acid contents by using generation mean analysis. The cross of lines Ⅲ174×Zi2. （F1）, F2. BC1 （F1×P1）, BC2.（F1×P2., and parents （P1 and P2. were evaluated in the field. Data were measured on individual plants for oleic acid, erucic acid, and glucosinolate contents. Transgressive variations in F2.population were observed for oleic acid content, indicating that dominance and recessive genes distributed in both parents. Scaling test indicated that the effects of genes controlling these characters did not follow the additivedominance model. The data for three characters were analyzed using six parameter models and found that one or more types of epistatic gene effects were important for glucosinolate content. High broad sense heritabilities were obtained for erucic acid, oleic acid, and glucosinolate contents with the values of 98.97%, 93.68%, and 86.17%, respectively. Two major gene pairs were found to control the expression of erucic acid and oleic acid contents, while three major gene pairs were detected to control glucosinolate content.
