perforated with 12 holes each 30 mm in diameter on a circle of 230 mm in diameter from the center (ISO/FDIS, 1997) and b) the KU design made of stainless steel rod of 1.80 m in length, fitted with a stainless disc of 230 mm in diameter perforated with 4 holes each 62 mm in diameter on a circle of 205 mm in diameter from the centre. Raw milk samples Prior to transferring milk from the truck to storage tank, milk from each chamber was mixed at uniform interval of 0, 5, 10, 15, 20, 25 and 30 times of stirring using both plungers. During each sampling time, 60 ml of raw milk were collected in plastic bottles of 80 ml capacity with the help of plastic jug from the top opening of each chamber. Samples were collected from all three chambers adopting the similar method and were analyzed for fat content and other milk compositions at the laboratory using calibrated ultrasonic milk analyzer, Ekomilk-M (Eon Trading, 2001). Statistical analysis Data were analyzed under a split plot in Completely Randomized Design (CRD) using PROC GLM in SAS. The statistical model used was Yijkl = µ + ρi + δk(i) + αj + β(ρ)il +ραij + εijkl where Yijkl was the dependent variable; µ was the overall mean; ri was the effect of chambers as main plots (i = 1, 2, 3), δk(i) was the main plot error; αj was the effect of stirrers (j = 1, 2); βl was the effect of stirrers (l = 1 and 2); β(ρ)il stirring times nested with containers; ραij was the interaction effect between the plunger and container, and εijkl was the subplot error at NID (0, σe 2 ). Statistical differences among different stirring times were analyzed using Duncan’s multiple range test (DMRT) according to Cody and Smith (1997). Kasetsart J. (Nat. Sci.) 40(1) 217 RESULTS AND DISCUSSION Milk composition The changing analysis values of milk composition sampling at various stirring times are illustrated in Table 1-3 for protein, solid-not fat (SNF) and fat respectively. The protein and SNF content in milk mixed with both plungers, stabilized after 5 times of stirring with no significant differences (p>0.05) with the rest of stirring times (Table 1 and 2), whereas the milk fat content statistically stabilized only after 10, 5 and 10 times of stirring for chamber I, II and III respectively (Table 3). The shortest time to attain homogeneity in protein content could be explained by its nature of existence in dispersion form of a very tiny particle size ranging from 10 -4 to 10 -5 mm (Tetrapak, 1995), which could be easily disturbed and redistributed with mild agitation. Whereas, early stabilization of SNF could be explained by early stabilization of protein, which was one of the SNF components and the other water soluble components of SNF, i.e. lactose, minerals and certain vitamins which existed in true solution. The early stabilization of protein and SNF could also be in part explained by the nature of variation of milk components, where fat showed the widest variation, followed by protein, lactose and then ash (Table 4) (Jenness, 1988). The difficulty in stabilization of fat content was caused by stratification of fat globules during storage or transportation from gravity creaming and also from the action of cold agglutinin. Fat globule tended to float due to lower density as compared to skim milk; depleting the fat content at the lower portion of the container forming cream layer at the surface. Creaming was reported to onset after 40-50 minute of milk holding after cooling to 5 °C (Goodridge et al., 2004). Comparative plunger efficiency Comparative effectiveness of KU versus ISO standard designed plungers using protein,
218 SNF and fat composition in raw milk as indicators are illustrated in Table 5-7. Using both types of plunger, protein and SNF stabilized after 5 times of agitation (Table 5 and 6). Milk fat content also attained homogeneity (p
