Produce buyers are not a homogeneous group. Buyers for grocery chainshave different needs than buyers for food service. For grocery items normallysold in bulk, processors want largest size packages that they can handleefficiently - to minimize unpacking time and reduce the cost of handlingor disposing of the used containers. Produce managers, on the other hand,want individualized, high quality graphics to entice retail buyers within-store displays.
¨ The positive effects packagings are the safe delivery of the productto the consumer while preserving the designed and processed usage and/oraesthetic values of the product. Packaging also plays an important role insaving natural resources by preventing the product to be wasted and the investedmaterial and physical labor getting lost. Since the value of the productgenerally far exceeds that of the package, the optimal product use, is moreimportant than the optimal package use. While the package prevents the productto be contaminated, it also prevents the environment to be polluted by theproduct. To summarise, the packaging is an important tool of optimal resourceuse.As many of the dairy powders manufactured have to travel long distances to reach their customers, both domestically and internationally, there is considerable interest among dairy powder manufacturers to maintain the quality of their products for relatively long storage periods. Dairy powders can have a long shelf life if packaged and stored properly. Vacuum packaging can be an attractive packaging strategy to maintain the quality of dairy powders and provide added value by improving the efficiency of using the storage space; because of the inherent compactness of these products. Vacuum packaged dry dairy ingredients may also have added ease of handling for end users. However, little is known about the impact of vacuum packaging on the physical properties of dry dairy ingredients. The main objective of this study was to determine the effect of vacuum packaging over 12 months storage on particle size, particle density, bulk density, tapped density, flowability, compressibility, color, moisture content, surface morphology, and solubility of six types of dairy powders. In addition, the effect of dairy ingredients type was also assessed. Commercial samples of nonfat dry milk powder, whole milk powder, buttermilk powder, milk protein Isolate, whey protein concentrate#80, and sweet whey powder were repackaged in duplicate using multi-wall foil side gusseted bags under varying degrees of vacuum (1, 0.7, 0.4 bar) and a control with no vacuum, then stored for 3, 6, and 12 months at 25°C and 60% relative humidity. Each powder was sampled and analyzed in duplicate for all the above listed quality attributes, upon receiving the powder and after 3, 6, and 12 months of storage.
