Background: The rising concern with environmental preservation has led to increasing interest in biodegradable polymer composites from renewable sources, such as cellulose and its derivatives. The use of nanocellulose is an innovative food packaging trend. Discussion: This paper presents an overview and discusses the state of the art of different nanocellulose materials used in food and food packaging, and identifies important patents related to them. It is important to consider that before marketing, new products must be proven safe for consumers and the environment. Conclusion: Several packaging materials using nanocellulose have been developed and shown to be promising for use as active and intelligent materials for food packaging. Other nanocellulose products are under investigation for packaging and may enter the market in the near future. Many countries have been adjusting their regulatory frameworks to deal with nanotechnologies, including nanocellulose packaging.

This study sought to: (1) identify the types and sources of Non-Timber Forest Products (NTFPs) traded; (2) find the frequencyof the NTFPs trade and (3) identify the challenges in NTFPs trading in the Sunyani Municipality. The survey was carried outfrom February, 2014 to April, 2014 mainly at the Sunyani Central and Nana Bosoma Markets in the Sunyani Municipality. Thetarget population comprised NTFPs collectors (gatherers), sellers and consumers. Respondents were purposively sampled. Atotal of 100 respondents were engaged in this study. The NTFPs were grouped into six categories namely; food, medicine,building materials, packaging materials, artefacts and domestic utensils. Key informants’ interviews were also conducted atthe Sunyani Forest Services Division to triangulate the data already gathered. Statistical Package for Social Sciences was usedto analyze the data obtained. The study demonstrated that domestic utensils (37%), food (33%), medicinal products (12%),packaging materials (9%), artefacts (6%) and building materials (3%) were the types of NTFPs traded in the two market centers.The results also showed that majority of the respondents (77%) harvest their NTFPs from forest lands as against 23% whoharvest from communal lands. A significant proportion of the respondents (52%) traded in above 40 kg of NTFPs and only 4%were seen trading in 10 kg of NTFPs. The study further highlighted that food (28%) and domestic utensils (26%) were regularlybrought to the market centers on weekly basis whilst significant proportions of medicinal products (9%), building materials(3%) and artefacts (4%) were brought to the market venues on monthly basis. Cumbersome permit procedure (40%), increasedmarket demand (15%) and financial constraints (20%) were identified as some of the challenges encountered in NTFPs tradingin the Sunyani Municipality. To ensure strict monitoring and sustainability of the resource, there is the need for sensitizationprogramme on the importance of NTFPs in rural livelihood and why their conservation is vital in meeting the needs of thepresent generation whilst not undermining their potential in supplying the needs of future generations.
