- ‘Active’ or ‘intelligent’ packaging
- For example, nanoparticle emulsions to improve texture (trickling agents) and reduce fat content
- Nanocapsulesenclosing nutrients such as vitamins or Omega 3 fatty acids (‘nanoceuticals’) for release into body when required

Safety of bottled water
Safety of soft drinks
Traditional foods are considered safe as they have long history of use. However, if they are modified by processing or by any other method their substantial equivalence and nutrient content analysis has to be done.
Method for safe preparation of some plants such as cassava are known in cultures that depend on it as a staple but its introduction into a naïve market place could cause cyanide poisoning.
Canned ackee fruit is prohibited into US until a quality assurance that toxic levels of hypoglycin is not present in product is given
Packaging innovation to ensure food safety as certain components of packing like printing inks, labels, colours, seals can affect food quality.
Innovative packaging like vaccum packaging, controlled atmosphere or modified atmospheric packaging (CAP or MAP). MAP involves sealing package under vaccum or one time gas flushing and sealing. Three types of gases may be used singly or in combination namely nitrogen, carbondioxide and oxygen.
Active Packaging – includes additives capable of scavenging or absorbing oxygen, CO2, ethylene, moisture, odour and flavours. May have powder sachet of iron and calcium hydroxide.
Provides way to monitor and relay information regarding the status of contents and verifies information. Food packaging manufacturers have developed several innovative intelligent packages that include time, temperature indicators, antitheft and use RFID devices.
Toxicity testing of food packaging materials have to be done in animals as human data are rarely available.

Imagine using nanotechnology to create self-healing materials or coatings that can modify agricultural materials or packaging to prevent microbial contamination;
scientists are eager to develop nanosizedgeotracers that enable users to locate precisely the origin of agricultural products.
In the wake of widespread food poisoning scares in spinach, tomatoes, cilantro, and peppers,
Nanotechnology is making revolutionary changes within cells which will improve agriculture and the food industry in amazing ways.
