More particularly, the present invention relates to a ready-to-feed powdered infant formula or a ready-to-feed powdered growing-up formula showing the desired gastric digestive properties. A nutritional composition is provided comprising casein, whey protein comprising alpha-lactalbumin (aLAc) and beta-lactoglobulin (bpac), and protein-coated fat droplets, wherein (i) the protein content of the composition is from 5% to 20% (w/w), preferably from 7-16% w, based on total solids; (ii) an aLac + bLac content of at least 25% (w/w) based on total protein level; (iii) the fat content is in the range of 10% to 50% (w/w) based on total solids; and (iv) the fat droplets are coated with an average protein load of 2-10mg/m2, and wherein the weight ratio of casein (aLac + bLac) on the fat droplets is at least 4 times, preferably at least 4.5 times the weight ratio of casein to whey protein in the total composition.)
