Milk was food that was composed of various nutritional values with a balanced proportion of milk weakness affects the shelf life so that it required a pasteurization process by adding kasumba turate (Cartamus tinctorius L) to milk as a natural colouring agent and preservative. To extend the shelf life, this study aimed to determine the effect of organoleptic quality (color, aroma and thickness) pasteurized milk with the addition of kasumba turate (Cartamus tinctorius L) at different storage times. This research was conducted using a Completely Randomized Design with different storage duration treatments (0 hours, 4 hours, 8 hours, 12 hours, 16 hours). The results of this study indicated that the addition of kasumba turate significantly affected the viscosity of milk, but did not affect the color, and aroma. This research can be concluded that during the storage of the organoleptic quality of color, the aroma of kasumba turate, the aroma of milk did not change but affected viscosity at different storage times.

Eggs are a rich source of animal protein, such as vitamins A, B, E, D, niacin and riboflavin, carbohydrates, calcium, phosphorus, fat and calories. Apart from having high nutrients, low prices and easy processing, eggs are a livestock product that is easily damaged. Efforts to overcome the damage, it is necessary to carry out preservation. Preservation of eggs can be done by soaking, dry and wet methods, covering the skin with preservatives and storing in a cold room. Soaking fresh eggs is done by soaking various solutions such as lime water, brine solution and filtrate or vegetable tannins containing tannins. The results of the proximate analysis of melinjo leaves contain a tannin concentration of 4.55% which is expected to be one of the vegetable tannins. This study used 176 duck eggs using a completely randomized design (CRD) with 4 x 4 factorial pattern each with 3 replications, consisting of 2 factors. The first factor was the level of melinjo extract (0%, 30%, 40% and 50%) and the second factor was the length of storage (1 day, 14 days, 21 days and 28 days). The results showed s emakin long storage time, the value depreciation egg weight and pH increased. The use of melinjo leaf extract can be used as a preservative starting from the level of 30%.
