| Outline of Final Research Achievements |
Stainless steel tubing is widely used in dairy industries. The deposits of milk components to internal surface of stainless steel tubing may cause deterioration in quality and food poisoning. Surface roughness is a factor affecting the attachment and removal of food soils. In this work, we studied cleanability of milk components on a highly-smooth internal surface with 0.01 micro meter Ra of stainless tubing. Three different levels of surface roughness of stainless steel tubings were tested to evaluate the cleanability. On the deposition test, whole milk was circulated in a tested loops connected with the tubings. After the deposition process, deionized water was flushed into the loops to remove milk deposition on the internal surface. At 40°C, the data showed that the smoother surface had a tendency to improve the cleanability of milk deposits. The results indicated that the highly-smooth internal surface has a potential to improve the cleanability of the milk deposits.
