Not all food items can be purchased fresh off the maker's or alternately merchant's racks. Check out the supermarkets and grocery stores - you will find that each food item has its own kind of packaging. An excursion down the walkway in the general store is sufficient to observe that. Even things that we consider 'fresh', like fruits and vegetables, on occasion end up packed for comfort and standardization.
The primary purpose of packaging different products is preservation. However, preservation techniques, accordingly, are not new. Go back to two or three generations, and you will remember our grandmas dealing with crude food like milk, vegetables, fish or meat in a method for broadening their timeframe of realistic usability. These were finished through drying, fermenting, curing, or in some cases, saving in vinegar. Today, we are in a time of commercial sterilization of canned food varieties, opening up the way to safe food items with long periods of usability.
Primary purposes of food packaging at a glance
Food packaging serves various needs. It safeguards food from getting polluted, contaminated or spoilt, and makes the package look appealing, in a real sense 'addressing' an expected buyer, while empowering the transportation of merchandise. Packaging holds the freshness of the product and keeps it away from exposure to biological and natural tainting. Thus, right from source to purchaser’s objective, packaging holds the actual uprightness and visual allure of numberless products.
Regardless of what things the package might contain, the packaging on outer surfaces accompanies names and other significant consumer-centric data that assists the buyers with choosing the right kind of products. Packaging traces food items through the making, handling and distribution stages – thus, it ensures the durability, quality and security of the products. Food packaging is basically the art and science of making the products look interesting and appealing to the customers while keeping them new and easy to eat.
One more significant reason for packaging, however less clear, is portion control. Making standardized portions assists with managing utilization. For instance, mass commodities like salt can be separated into packages that are a more reasonable size for a family. The packaging additionally assists with tracking of stock, such as selling fixed containers of milk, as opposed to having individuals carry their own pots to fill themselves.
Packaging materials
Food packaging materials makes use of different materials. Some of them include plastic, paper, cardboard, aluminium, jute, fabric, glass, and others. Different packaging materials safeguard food from various kinds of exposures including daylight, gases, and dampness. A packaging material made of glass and metal shields food from microbes and synthetic compounds. Organic packaging materials incorporate paper, cardboard and padding materials, which keep food from being ousted and getting squashed during packaging, transport, and racking.
Frozen Food Varieties
One of the most commonly involved techniques for
food packaging is freezing, which can be possible in various ways. Both processed, ready-to-boil/eat food varieties, as well as vegetables, green peas and corn can be freeze-packaged. Frozen food varieties are packed in hermetically sealed sacks to keep them new and tasting great.
Consumer demand and packaging strategies
Buyers today are not happy with safety alone but at the same time are demanding nutritious and more delectable food varieties. Overall, the packaging business' experience has been that heat-processing sterilization is not the right answer. Rather, practices need to be adopted for dynamic packaging techniques, where food sources are not exposed to high temperatures so they taste fresh and great. Here, antimicrobial food packaging assumes a key role.
We are in an era where the development of more robust materials and mixtures of bioactive stuff in packaging films have brought a revolution in the food Industry. There are additionally cutting-edge methods for the detection of emerging as well as existing food-borne microbes. When the microbial risk for each kind of food item is well-known, and microbial targets are definitively identified, it is feasible to figure out what bioactive compound will be more suitable for every particular application.
In this sense, bacteriocins, for example, nisin or pediocin are being considered for the dynamic packaging of food, while more compounds are additionally coming into the picture. Moreover, there are likewise other bioactive plant-derived products, as well as new-age components from nanotechnology for specific food packaging applications. Not all these numbers of active compounds are endorsed by the administrative bodies at this point. However, it has set off serious innovative work in this sphere, which makes certain to produce enthusing advances and would ideally satisfy consumers, administration and industrial requirements alike.
Trends in food packaging
One aspect that industry associations mutually settle on is that the utilization of smart markers in food packaging will go to a new high. There are various kinds of indicators with various advantages to food makers, buyers and retailers. Then, advanced temperature information loggers will come into use, to quantify and record the temperature history of food shipments. This information can be downloaded and investigated, through which the remaining period of usability of the item can be determined. On account of temperature limits, restorative measures can be taken. Standardized identifications are applied to food packaging to make sure that all products are accurately packaged and date-coded.
The stand of Indian packaging materials manufacturers
Over the past 2 decades, Indian manufacturers have earned a formidable reputation around the globe by delivering world-class packaging solutions to customers belonging to diverse industry verticals. These companies have invested hugely in setting up robust research and development laboratories to come out with first-of-its-kind packaging solutions for food producers, consumers, and retailers.
