Commercially, sugar is available in a variety of formats that can be divided into categories according to their purity, treatment, shape or color and presentation. Thus, besides the pure sugar, also sugars that have been enriched with additives for special applications as well as special products exist. Today, the food industry processes 83% of the sugar produced mainly for drinks as well as sweets and candies. Seventeen percent of the sugar produced is packaged and sold in small quantities directly to consumers. Sugar has different uses in domestic kitchens and industry: to preserve jams, cakes or cooked as cooking ingredients and of course, as a sweetener in coffee or tea. In the sugar market there are two types of products, raw sugar and refined or white sugar, both available as packages or sold them loose. We study the packing cases each.
Sugar packaging has advantages and disadvantages according to their presentation and packaging; sugar usually comes packaged with different materials, the most predominant are plastic packaging, paper and packaging made with vegetable fibers. Packing sugar makes it safer and less vulnerable to pollution. Sugar lasts longer and stays fresh longer when is packed correctly.
Advantages of plastic packaging:
It presents variety of forms, suitable for easy handling. Material density determines the resistance of the package. These can be manufactured with high resistance to tearing up unbreakable containers. Its great advantage is the impermeability to moisture and light, which prevents contamination of sugar and its better preservation.
Disadvantages of plastic packaging:
If the packaging material comes in contact with other products of strong odor and flavor, sugar absorbs these smells and tastes. Likewise it not withstands high temperatures, and depending on the material strength it can melt in more or less time. Besides producing solid waste, seriously affect the environment and that is not a biodegradable material.
Advantages of Paper packaging:
The advantages offered is that the sugar is better preserved because the air is absorbed and thus dust particles or soot and light do not have easy access. In addition it is good for the ecology because they can be recycled in its entirety without difficulty.
Disadvantages of paper packaging:
Some disadvantages are the fragility of the material; paper rupture are very common and if water is present can also be ruined packaging.
Advantages of the packaging plant fibers:
This type of packaging is very economical and they are not highly polluting.
Disadvantages of packing vegetable fibers:
Often it is a material that attracts any pest
Advantages of loose sugar:
One advantage of the loose sugar use is it decreases dramatically the amount of solid waste sent to the environment. Moreover, the consumers purchase only what they need to avoid the waste of food, they can also view product quality due there is no packaging to avoid it. Another advantage is that it allows considerable savings for producers and distributors (the packaging is removed and logistics simplified).
Disadvantages of loose sugar:
Unpacked sugar may dry quickly; you may appear mold or can be put in disrepair.
