变褐

Using orthogonal experiment, the effects of biological inhibitors on longan pericarp browning and the freshness quality were analyzed.

采用正交试验方法，分析了生物抑制剂对龙眼果皮褐变和保鲜效果的影响。

Polyphenol oxidase activities were determined spectrophotometrically at 410 nm with pyrocatechol as substrate at different levels.

为探明乌龙岭龙眼贮藏保鲜过程中的褐变问题，以C6H6O2为底物，采用分光光度法研究了底物浓度对龙眼果皮PPO活性的影响规律。

The experimental results showed that the crude toxin of Phytophthora capsici could inhibit the germination of seeds, the growth of seedlings, and the growth of pepper radicel and the callus of pepper extremely.

结果表明，粗毒素能使辣椒叶片产生与疫病病原菌侵染类似的水渍状褐腐斑，抑制辣椒种子的发芽率，抑制辣椒幼苗和胚根的生长，抑制辣椒愈伤组织生长，并且粗毒素的这些抑制作用随着其浓度的升高而变强，不同品种所得出的实验结果一致。

The influences of maturity, rhizome size and environmental conditions on browning enzymes were also discussed.

并探讨了品种熟性、藕体大小和环境条件对莲藕褐变酶的影响。

The activities of enzymes including Polyphenol Oxidase, Superoxide Dismutase, Catalase, Peroxidase and the contents of soluble protein, phenolics contents and varieties in the pericarp, sarcocarp and core of the pear fruits were measured.

以黄金梨、大香水、新梨七号为试材，研究了贮藏后梨褐变不同部位酚类物质含量和种类、多酚氧化酶、超氧化物歧化酶、过氧化氢酶、过氧化物酶的活性及可溶性蛋白的关系。

In 1846, Browning married Elizabeth Barrett, a famous poetess who was a semi-invalid and had been strictly confined home by her domineering father.

1846年，伊丽莎白巴雷特结婚褐变，一位著名女诗人半无效，已严格限定由她盛气凌人的父亲回家。

The cells protrude as semisphere.

褐变前、霉变前后果实失重率大。

Meanwhile, the experiment of three factors and three levels,whose influential factors are the kind and concentration of reagent for controlling nonenzymatic browning and the soaking time,is carried out and the results show that the optimal technological condition for controlling nonenzymatic browning is to soak the material in 2% edible citrin solution for 45 min before the material is blanched.

同时以抑制剂种类、浸泡液质量分数及浸泡时间为影响因素，进行了三因素三水平试验。结果表明，将原料在灭酶前用2%的食用柠檬酸溶液浸泡45 min为抑制非酶促褐变的最佳工艺条件。

A higher level of sulfhydryl compounds wasobserved as fruit stored at low temperature.

低温贮藏时果实组织虽保持较高的巯基化合物水平，但巯基化合物DTT处理并不影响荔枝褐变的进程。

The browning utensil is the only utensil you should put in the microwave without food in it.

褐变皿是唯一皿你要提出的微波炉没有食物。。。。。。。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
