lotions and lip balms (Rongrong et al. 2010). Gelatin-edible films have captured the
limelight for a quite a short while now due to their efficient lipid barrier properties
and film-forming capacity. However, the inclusion of bioactive compounds is
necessitated by the high water-binding properties of the films which in turn cause
swelling. Hemp oil has also been used in gelatin-edible films in order to increase
their antimicrobial strength. Incorporation of hemp oil in gelatin-based films had
exhibited to increase its solubility and light barrier property and subsequently
decrease film thickness (Cozmuta et al. 2015).
15.8 By-product Applications
The hemp hurd is a by-product of the hemp plant obtained during hemp fibre
separation. Generally, hemp hurd has been used as animal bedding (Khan et al.
2015). In order to produce hemp powder, hemp hurd is milled to different particle
size distributions. Hemp hurd powder serves as a good filler for plastic-reinforced
composites. In addition, it has been incorporated in the filament material used for 3D
printing that plays a crucial role in developing a 3D food printing arena. On the other
hand, hemp powder is used for the production of high specific surface area-activated
carbon (Khan et al. 2015). Recent studies have revealed that industrial hemp can
produce by-products such as hemp hurds and hemp dust which can prove to be a
source of high value-added hydroxycinnamic acids (HCA), namely, ferulic and
p-coumaric acids (Candy et al. 2017).
The hemp fibre has demonstrated to possess excellent antimicrobial properties
and is therefore a major component of functional textiles. Moreover, the hemp hurd
and powder are also examined to possess antibacterial properties. They have been
used to eliminate the occurrence of Escherichia coli. Incorporating hemp hurd
powder into the composites is certain to yield a lighter product with enhanced
antimicrobial activities. Hemp hurd powder can be used to produce eco-friendly
food packaging composites (Khan et al. 2015).
15.9 Future Challenges
The efficiency of the oil recovery from hempseeds can be enhanced by advancement
in design and development sector of processing equipment. Currently, fewer studies
are undertaken for examination of quality and grade of the oils available in the
market. Poorly processed hempseed was investigated to possess psychoactive compound, Δ-9-tetrahydrocannabinol (THC). In Australia and New Zealand, consumption of hemp-derivative food products containing a trace level of THC is proposed.
However, studies revealed that on consumption of low-content THC oil (5 mL
bearer sesame oil containing 10 mg/kg THC), there was negligible detection of
THC in oral fluid, blood or urine samples (Hayley et al. 2018).
