可是读一年foundation在UCSI也不错啊。
过后再回来读food science。
原来你在singapore读了13年,中文还不错啊。 |

并不是在新加坡读书的华文就一定不好。。。
无知的新加坡人说我是叛国贼,不在本地读书跑到新加坡读。。。
但我的华文程度也不会烂到给新加坡人看不起。。。
我想,等我读完UOL后,我已经没有这个精力去读food science了咯。。。
哈哈。。。 |

有一部分的新国人很看不起马国人。
没关系,要为我们马国争光。
你现在假期还是在读书呢?
考上UOL需要什么资格?
多少A? |

哇。。。
好厉害。。。
但是你为什么选择去读food biopolymer?
我哥哥现在在NUS读master in nanotechnology...
感觉我没有那种命去读master吧。。。哈哈!
看了phil大大和你的生活真是多姿多彩。。。
是Food Technology分出来的,我做的研究是尝试改变蛋白质的构造。 |

你现在读USM是吗?
不懂是不是靠近我家那间。
哈哈。
你的文章有send去英国教授那里的吗?
只要成绩好,都可拿奖学金?大约3.8以上吧?
但是你不需要申请吗?你说lecturer直接offer你,那应该是太好了。
food ...
我在usm main campus,你家靠近main campus 吗?
第二篇文章是邀请英国一个权威教授当co-author。拖了我这么久。
lecturer 会offer,但我也有申请,价钱比较高。
煮东西也有啦,但并不是主要的。 |

aier,我现在有开始吃葡萄籽grapeseed, 你可以试试看。
喝多些水,1-2L可能对你身体不够。
你最严重便秘多久一次?
我每天早上都会大号,有时1天2次,晕。
故我所知,我听我朋友说她有便秘的,我发现两边 ...
grapeseed extract是以高抗氧化剂为卖点,对心脏,血管,老化,眼睛等问题有帮助。不过便秘就应该不大可能帮到啦。
现在的天气和污染,upgrade到3公升啦
基本上一个正常的健康人应该是吃多少餐,大多少次便的,1天2次对每天3餐来说已经是略嫌不足 |

Sodium Hydroxymethlyglycinate 也是值得争议下,是源自Glycine(甘氨酸,是20个氨基酸中最简单的一个),蛋白质的一种。Paraben及Sodium Laurel Sulphate呢,是源自Benzoic Acid (苯甲酸)。Sodium Hydroxymethlyglyc ...
看了一篇报告关于防腐剂的。。说到很多人都说Grapefruit Seed Extract (GSE) 是天然防腐剂,其实不然。
"GSE is no more natural than parabens. Chemical manufacturers take the left over grapefruit pulp, a waste by product from grapefruit juice production, and in an intensive multi-step inductrial chemical process, change the natural phonolic compounds into synthetic quarternary ammonium compounds.
Synthetic ammonium chloride is one of the chemical catalysts used in the process.
So all GSE is a chemically altered form of grapefruit seed."
这是真的吗? |

哗,是真的。我access进Journals,做了Latest 的考察。请允许我用英文回答。
Grapefruit seed extract (GSE) is promoted as a natural product that has reported antibacterial and antiviral properties. It is reported by the manufacturer to be safe and effective to use internally and externally for a wide variety of conditions such as acne, allergies, athlete’s foot, body odor, candida, colds, cold sores, gastrointestinal infections, gingivitis, impetigo, parasitic infection, sinusitis, sore throat, and thrush (1, 2). It is sold in health food stores and is widely available on the Internet.
There is recent evidence that some commercial GSE is adulterated with synthetic preservatives and that these additives are solely responsible for the antimicrobial activity of these products. Sakamoto et al. (3) found the preservative agents methyl 4-hydroxybenzoate (methyl paraben) and 2,4,4¢-trichloro-2¢-hydroxydiphenyl ether (triclosan) in commercially available GSE but not in ethanol extracts of grapefruit seeds. The identities of the preservatives were confirmed by comparing their high performance liquid chromatography (HPLC) retention times and absorption spectra with those of authentic standards, whereas triclosan was additionally confirmed by liquid chromatographymass spectrometry (LC-MS) using negative ion electrospray ionization. The presence of methyl paraben and triclosan was later confirmed by von Woedtke and co-workers (4), who also identified benzethonium chloride (Figure 1) in these products. Using thin-layer chromatography (TLC) as their analytical method these researchers reported that five of the six commercial GSE contained between 1.25 and 10% benzethonium chloride, whereas levels of 0.0125 and 0.025% triclosan were present in three samples. Methyl paraben was detected in three GSE samples, although no concentrations were reported. Five of thecommercial GSE samples that contained one to three preservative substances showed high growth inhibition against Bacillus subtilis SBUG 14, Micrococcus flavus SBUG 16, Staphylococcus aureus SBUG 11, Serratia marcescens SBUG 9, Escherichia coli SBUG 17, Proteus mirabilis SBUG 47, and Candida maltosa SBUG 700. Dose-response curves of the three preservative agents on the seven microbes tested revealed that benzethonium chloride was responsible for most of the antimicrobial activity observed. Only one of the six commercial GSE samples was preservative-free, and this sample did not exhibit any antimicrobial activity. The authors made their own GSE samples by hot and cold extraction of grapefruit seeds and juiceless pulp using glycerol, water, and ethanol as well as mixtures of these solvents. These samples also did not have any antimicrobial activity. It was concluded that the potent antimicrobial activity attributed to GSE is due to the synthetic preservative agents, with benzethonium chloride being responsible for the majority of activity. One of the manufacturers later claimed that their product does not contain benzethoniumchloride and that the error was due to the similarity in molecular weight of the quaternary ammonium compound (said to be formed in the proprietary manufacturing process) with that of benzethonium chloride. However, the presence of 8% benzethonium chloride in commercial GSE was conclusively demonstrated by the use of HPLC, one- and two-dimensional NMR (5), proton-induced X-ray emission (PIXE) analysis, and electrospray ionization mass spectrometry (6). In a case reported to the Swedish Medical Products Agency (MPA) two patients prescribed to warfarin experienced adverse effects upon self-medication, using a commercially available GSE product (7).
The composition of GSE is not revealed by those manufactures. Whilst, most of the recent literatures revealed that this commercial GSE product contained harmful substances, therefore, I personally believe that this is a truth that should aware the consumers.
