| 摘 要： | 利用超高压射流对撞式/碰撞式技术处理液态奶,考察其相对密度、滴定酸度、pH值、灰分碱度、浊度、颗粒粒径等理化性质。结果表明,超高压射流处理后,液态奶的灰分碱度及压力≥200 MPa时滴定酸度均符合灭菌乳国家标准(GB5408.2-1999);相对密度保持不变;浊度呈上升趋势;对撞方式均质效果明显优于碰撞方式。超高压射流处理牛奶的最佳工艺为200 MPa对撞方式处理。该研究为超高压射流杀菌奶的后续深入研究奠定了基础。 |

| Abstract: | Liquid milk was treated by ultra-high pressure jet(clash/collision),in order to study its phy-chemical properties of relative density,titrable acidity,PH,ash alkalinity,turbidity,partical size.The result indicates that after liquid milk treated by ultra-high pressure jet,ash alkalinity is accordance with the national standard of sterilized milk(GB5408.2-1999),and it is also with titrable acidity when the pressure was no less than 200 MPa.Relative density remains the same,while turbidity has a rising trend.T... |
