The physiological causes of the core browning of pear fruit during storage were studied.The polyphenol oxidase activity in the core,flesh and skin were determined and the site of highest activity was found in the core.The distribution of the total polyphenolic content in the different parts of the pear fruit was similar to that of polyphenol oxidase activity.In the brown core the amount of the polyphenolic subs- tances decreased markedly as compare with the normal ones The separation and identification of the...

The physiological causes of the core browning of pear fruit during storage were studied.The polyphenol oxidase activity in the core,flesh and skin were determined and the site of highest activity was found in the core.The distribution of the total polyphenolic content in the different parts of the pear fruit was similar to that of polyphenol oxidase activity.In the brown core the amount of the polyphenolic subs- tances decreased markedly as compare with the normal ones The separation and identification of the polyphenolic substances were carried out by paper chromatography and high voltage electrophoresis.Seven compounds were found in the core,five in the flesh and six in the skin.The chlorogenic acid was the major component. The ultraviolet spectra of the chlorogenic acid oxidized by the polyphenol oxidase indicated that the absorption peak of chlorogenic acid at 324 mμ decreased after the oxidation.The absorption spectra gradually increased toward the utraviolet region, and was similar to that of the natural brown product of pear fruit. These results show that the physiological cause of the core browning is due to the enzymic browning reaction and the principal substate in the core is chlorogenic acid.

通过对鸭梨贮存过程中发生的黑心病问题的研究。发现:(1)多酚氧化酶活性和总多酚类化合物的含量,在鸭梨果实的不同部位中是不相同的,果心最高、果皮次之、果肉最低。当鸭梨发生黑心病后,果心总多酚类化合物含量下降。(2)应用纸上层析和高压电泳对多酚类化合物进行分离和鉴定。证明在果心内有7种多酚类化合物,在果肉中有5种,果皮中有6种。其中以绿原酸为多酚类化合物的主要成分,并在果心内的含量最高。(3)鸭梨黑心后绿原酸在果心内的含量下降。应用绿原酸作为多酚氧化酶的作用底物,酶作用后绿原酸在324毫微米的最大吸收峰下降,在200毫微米处出现新的最大吸收区,与鸭梨自然褐变产物相似。根据以上实验结果,我们认为多酚类化合物的酶促褐变是造成鸭梨黑心病的生理原因,绿原酸可能是主要的产物。

Under a certain experimental condition, a-type of heavier rare earths chelates of chlorophosphonazo (III) can be converted to β-type. In continuous scanning spectrogram, it is shown that α-type is formed instantaneously. The α-peaks decline and the β-peak raises when the reaction is in process. when Yb:R = l :1 and pH = 3.2, we had determinated at constant temperature that the order of reaction is equal to 2 and 1 for nonbuffer system and buffer system (NaAc-HCl) while apparent activation energy is equal to...

Under a certain experimental condition, a-type of heavier rare earths chelates of chlorophosphonazo (III) can be converted to β-type. In continuous scanning spectrogram, it is shown that α-type is formed instantaneously. The α-peaks decline and the β-peak raises when the reaction is in process. when Yb:R = l :1 and pH = 3.2, we had determinated at constant temperature that the order of reaction is equal to 2 and 1 for nonbuffer system and buffer system (NaAc-HCl) while apparent activation energy is equal to 71.7 KJ/mol and 49.8KJ/mol, respectively. For many buffer systems of interest, it is clear that buffer medium of having nucleophilic groups can accelerate the converted process. In these buffer systems the observed formation rate of β-type chelates decreases with increasing of hydrogen ion concentration and increases with the buffer medium concentration. The experimental result tells us that two a-type molecules combine into a β-type molecule and liberate a proton at the same time. With these information, therefore, we can suggest a reasonable mechanism for nonbuffer system-and the differential rate equation, obviously, is-For buffer system a reasonable mechanism will be. The differential rate equation becomesIn accord with these results, we can satisfactorily explain all experimental facts. At last, the geometrical configuration and the reaction mode are discussed in this paper.

一定条件下,偶氮氯膦Ⅲ的重稀土螯合物可由α型转化成β型。连续扫描的谱图表明:α型是瞬时形成的。随着反应进行,α峰下降而β峰上升。在恒溫、Yb:R=1:1和pH=3.2时,测得非缓冲体系和缓冲体系(NaAc—HCl)的反应级数分别为2和1,表观活化能分别为71.1KJ/mol和49.8KJ/mol。对于许多缓冲体系,具有亲核基团的缓冲介质能够加速此转化过程。在此缓冲体系中,β型螯合物的生成速率随氢离子浓度的增大而减小,随缓冲介质浓度增大而增大。实验还表明:两个α型分子形成一个β型分子并释放出一个质子。据此,对缓冲体系和非缓冲体系分别拟出了合理的机理,稳态处理后的动力学速率方程满意地解释了所有实验事实。最后讨论了反应机理的可能模式。

The impact toughness, low frequency internal friction and TEM examination were tested for steels 40Mn2, 40Mn2Mo and 30CrMnSiNi2. Experimental results indicate that the appearance of high temperature temper brittleness in these steels seems to be always accompanied by the decrease of Koster peak heights. The mechanism of this phenomenon may be explained as the result of an aging process of α-α-solid solution with precipitation of Fe_3C(N)particles causing pinning of dislocations and thereby decreasing the impact...

本文对40Mn2,40Mn2Mo及30CrMnSiNi2钢进行了冲击性能试验、低频内耗测定及透射电镜薄膜观察。结果表明,这几种钢高温回火脆的出现总是伴随着Koster峰的下降。高温回火脆的产生系由钢中α固溶体的时效现象所引起,沉淀出的Fe_3C(N)对位错有质点型强钉扎作用而使韧性下降。
