“…However, only 10% of rambutan peel is derived to use for food purposes such as polysaccharide gel (Prakash Maran and Priya, 2014) and anthocyanins (Sun et al, 2011). The peel is quite extensively explored for non-food applications of biosorbent (Rubcumintara et al, 2012), activated carbon (Ahmad and Alrozi, 2011a;Ahmad and Alrozi, 2011b;Njoku et al, 2014), biocomposite (Ooi et al, 2011, Ooi et al, 2012aOoi et al, 2012b), and biomimetic synthesis (Yuvakkumar et al, 2014a;Yuvakkumar et al, 2014b;Yuvakkumar et al, 2015).…”

Recent rapid growth of the world's population has increased food demands. This phenomenon poses a great challenge for food manufacturers in maximizing the existing food or plant resources. Nowadays, the recovery of health benefit bioactive compounds from fruit wastes is a research trend not only to help minimize the waste burden, but also to meet the intensive demand from the public for phenolic compounds which are believed to have protective effects against chronic diseases. This review is focused on polyphenolic compounds recovery from tropical fruit wastes and its current trend of utilization. The tropical fruit wastes include in discussion are durian (Durio zibethinus), mangosteen (Garcinia mangostana L.), rambutan (Nephelium lappaceum), mango (Mangifera indica L.), jackfruit (Artocarpus heterophyllus), papaya (Carica papaya), passion fruit (Passiflora edulis), dragon fruit (Hylocereus spp), and pineapple (Ananas comosus). Highlights of bioactive compounds in different parts of a tropical fruit are targeted primarily for food industries as pragmatic references to create novel innovative health enhancement food products. This information is intended to inspire further research ideas in areas that are still under-explored and for food processing manufacturers who would like to minimize wastes as the norm of present day industry (design) objective.

“…In the present work, SnO 2 nanocrystals were prepared employing rambutan peel extract mediated green synthesis route without surfactant and template at room temperature incubation and aging over a period of 1, 4 and 7 days. The utilized rambutan peels has the capability of ligating SnO 2 nanocrystals [31][32][33][34]. 1, 4 and 7 days of incubation and aging treatment increased the size, crystallinity and pure phase of the obtained cassiterite type tetragonal rutile SnO 2 nanocrystals which could be useful and applied for potential industrial applications.…”

The effect of incubation and aging on cassiterite type tetragonal rutile SnO 2 nanocrystals employing green synthesis technique has been investigated. The incubation and aging affected the compositional and morphological properties of SnO 2 and not influenced the structural properties of nanocrystals. The incubation and aging further influenced the particle shape and size of the obtained product. XRD results of the obtained product unambiguously revealed the cassiterite type tetragonal rutile phase of SnO 2 nanocrystals. The characteristic Raman peaks observed at 249, 476, 631 and 773 cm -1 were respectively revealed infrared active (E u ), Raman active (E g ), (A 1g ) and (B 2g ) vibration modes of pure tetragonal rutile SnO 2 structure. 3d 3/2 and 3d 5/2 of XPS peaks observed at 496 and 487 eV was clearly revealed the Sn 4? state in tetragonal rutile structure. The obtained TEM micrographs clearly revealed that the grain size and agglomeration was increased at higher incubation and aging treatments.

“…The nickel oxide (NiO) is obviously p-type semiconductor and has a relatively wide band gap energy in the range of 3.6-4.0 eV among the various oxides materials [2]. Because of its unique electronic structure [3], NiO nanoparticles have an extensively application research field [4], such as photocatalysts [5], photovoltaic devices [6], gas sensors [7], solar cell [8] and electrochromic film [9]. A lot of synthetic method have been introduced to synthesize NiO nanoparticles [10], such as sol-gel method [11], spray pyrolysis [12], sputtering [13], microemulsion method [14] and hydrothermal technique [15].…”
