Plant tissue culture has been successfully integrated into plant transformation strategies. Meristem culture has become immensely popular as micro propagation technique for the rapid production of commercially viable plants at industrial level. Meristem culture is also significant for obtaining virus free plant and additionally, meristem culture in combination with other techniques is applied in plant improvement as in production of transgenic plants, plant germplasm storage, regeneration of quality planting material or seeds in association with aeroponic or hydroponic systems.

Nanotechnology is a new emerging technology which has applications in different areas like it plays an important role in food sector and is used during food processing and food packaging. Nano-food may provide proper nutrient supplements like iron, vitamins, proteins and essential minerals. Nanotechnology is also self-assured to develop quality food packaging materials and can reduce plastic use. Scientists also going to develop nm sized salt grain particles that may increase surface area; hence our food materials require very less salt to give our taste buds that will cure high blood pressure. Beer bottles made by Plastics are used by many brewer SABMiller that contain a layer of nano-particles of clay that easily separable and filled more space in walls of beer and makes it harder for fizzy CO2 to free from the beer or for O2, that spoil the flavor of beer. There are many Government stakeholders and agencies to determine limitations and release demonstrative prescription and proclamation, as early as possible before-food packaging by nano materials that may have considerable impacts on health of human being. This review focused on the availability of nanofood packaging, processing and their supplements in the current market.
