Samples were subjected to high pressure ranging from 100 to 500 MPa. After high pressure treatments, the flavour compounds were extracted by Solid-Phase Microextraction. Analysis was carried out by Gas Chromatography-Mass Spectrometry. The key flavour compounds of orange juice were three alkenes (namely limonene, myrcene and α-pinene), two alcohols (linalool and α-terpineol), three aldehydes, one ketone and two esters (ethyl butyrate and 3-OH-ethyl hexanoate).

IT is thought the skin have so much member ,but the water's contain to 70％ and for the skin leading in physiology ,so that forn he's water principle theory——he thought ,the skin not better absorb for the effect component and illness or senescence whether it from the skin and the body's others but common qround is the same for the run short of the water in the cell and conjunctive tissue .in his manufacture in 1998 the new name came out and was named ——TORSION .for the technology he make use of the cosmetic ordinary 's drink aqua and lock the water capability when you use it , not only can keeping the skin have plenitudinous moisture,so that the skin deeply suck then using the ordinary cosmetic drink component hillpear mellow molecule deriive 's than hillpear mellowdrink's capability high 1~2 times for β- hillpear mellow.

他认为虽然皮肤有多种成分，但水分却占到了70％，对皮肤的生理肯定起着主导性作用，基于此形成了他的Water principle研究理论。认为皮肤对有效成分的吸收不彻底，以及疾病或衰老，无论它来自皮肤还是身体的其他部位，其共同点都是一样的，那就是在细胞和结缔组织中缺少了水。在他的精心研制下，利用化妆品常用的吸水剂山梨醇分子衍生出比山梨醇吸水剂吸水能力高出1-2倍的β—山梨醇，大大提高了皮肤的补水和锁水能力，使皮肤保持充足的水分，从而使肌肤对化妆品有效成分的吸收更为彻底。通过上万例的化妆品配方应用试验后，此技术于1998年在雅邦国际化妆品研究机构得到了推广，并利用Makinsdi.Dr的研究办公室作为新品的命名—TORSION。
