“…In fact, a low extract concentration resulted in a more homogeneous particle size distribution [ In this work, the shell presents a more homogenous but roughened disposition. This is concordant with results obtained by Iahnke et al with the incorporation of beetroot in gelatin films [60] and Harini et al who studied a film based on walnut shell fiber and cashews [44].…”

“…There are two more peaks to be observed between 3007.26 and 3007.59 and also 2934.24 and 2923.27 cm −1 , which are due to the presence of aliphatic and unsaturated hydrocarbons related to terpenoid compounds [ 43 ]. The 3007.26–3007.59 cm −1 peak is not found in the control nor in the shell extract, which indicates that it is a compound that can only be found in the walnut, like vitamin E. The second peak 2934.24–2923.27 cm −1 is also not found in the shell extract, which could be due to the amorphous cellulose found in the shell [ 44 ].…”

Phenolic compounds that come from natural products are a good option for minimizing lipid oxidation. It should be noted that these are not only introduced directly into the food, but also incorporated into edible biofilms. In contact with food, they extend its useful life by avoiding contact with other surface and preventing deterioration air, one of the main objectives. In particular, gelatin is a biopolymer that has a great potential due to its abundance, low cost and good film-forming capacity. The aim of this study has been to design and analyse gelatin films that incorporate bioactive compounds that come from the walnut and a by-product, the walnut shell. The results showed that mechanical and water vapor barrier properties of the developed films varied depending on the concentration of the walnut, shell and synthetic antioxidant. With increasing walnut concentration (15%) the permeability to water vapor (0.414 g·mm/m2·day·Pascal, g·mm/m2·day·Pa) was significantly lower than the control (5.0368 g·mm/m2·day·Pa). Furthermore, in the new films the elongation at the break and Young’s modulus decrease by six times with respect to the control. Films with pure gelatin cannot act as an antioxidant shield to prevent food oxidation, but adding pecan walnut (15% concentration) presents 30% inhibition of the DPPH stable radical. Furthermore, in the DSC, the addition of walnut (15 and 9% concentrations), showed the formation of big crystals; which could improve the thermal stability of gelatin films. The use of new gelatin films has shown good protection against the oxidation of beef patties, increasing the useful lifetime up to nine days, compared to the control (3–4 days), which opens up a big field to the commercialization of meat products with lower quantities of synthetic products.

“…This result is higher than those reported for pomegranate peel extracts obtained from the co-product of juice extraction with TPC values of 54.54 [38] and 19.30 mg GAE/g [24], and pomegranate seed flower with TPC of 40.60 mg GAE/g [32], respectively. However, a TPC value of 81.15 mg GAE/g was reported by Harini et al from pomegranate peel ethanolic extracts [39]. Regarding antioxidant activity, the extract concentration required to cause 50% reduction in the initial concentration (IC 50, mg/mL) values obtained from 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azinobis(3-ethyl-benzothiazoline-6-sulphonate) (ABTS) methods were 3.81 ± 0.05 and 3.95 ± 0.04 mg/mL extract, respectively.…”

Gelatin-Based Antimicrobial Films Incorporating Pomegranate (Punica granatum L.) Seed Juice by-Product

et al. 2019

Pomegranate (Punica granatum L.) seed juice by-product (PSP) was added as reinforcing and antimicrobial agent to fish gelatin (FG) films as a promising eco-friendly active material for food packaging applications. A complete linkage analysis of polysaccharides in PSP showed xylan and cellulose as main components. This residue showed also high total phenolic content and antioxidant activity. Three formulations were processed by adding PSP to FG (0, 10, 30 wt. %) by the casting technique, showing films with 10 wt. % of PSP the best performance. The addition of PSP decreased elongation at break and increased stiffness in the FG films, particularly for 30 wt. % loading. A good compatibility between FG and PSP was observed by SEM. No significant (p < 0.05) differences were obtained for barrier properties to oxygen and water vapour permeability compared to the control with the incorporation of PSP, whereas water resistance considerably increased and transparency values decreased (p < 0.05). High thermal stability of films and inhibition against S. aureus were observed. The addition of PSP at 10 wt. % into FG was shown as a potential strategy to maintain the integrity of the material and protect food against lipid oxidation, reducing huge amounts of pomegranate and fish wastes.

“…Researchers have reported the use of different types and different parts of plant for the extraction of nanocellulose. Alila and coworkers (Alila et al, 2013) used non-woody plants such as basts of flax, hemp and jute and leaves of sisal and abaca; Harini et al (2018) and Bano and Negi (2017), Marett and collaborators (Marett et al, 2017) and Naduparambath et al (2018) used shells of walnut, groundnut, pistachio and sago, respectively. Cherian et al (2010), Basta et al (2014), and Manzato et al (2017 used pineapple leaves, rice straw, soy hull, and tucuma's endocarp, respectively.…”

Non-woody Biomass as Sources of Nanocellulose Particles: A Review of Extraction Procedures

et al. 2021

Nanocellulose has been reported to be a very useful biomaterial with applications in biomedical, pharmaceutical, built industry, automobile, aerospace and many more. Its advantages over synthetic fibers include renewability, energy efficiency, cost effectiveness, biodegradability and good mechanical and thermal properties. However, the production of cellulose nanoparticles (CNPs) has focused more on woody plant sources. Non-woody biomass constitutes a large group of plant sources that are yet to be given the proper attention for utilization as raw material for nanocellulose particle production. This group of lignocellulosic biomasses is generally obtained as waste from farming activities, home gardens or office wastes. They are majorly composed of cellulose, hemicellulose, and lignin. However, their composition varies widely from one plant source to another. The variation in their composition results in limitations in the procedures employed in extraction of CNPs and of processing of the extracted CNPs. This means that different biomasses may have different ways by which CNPs are extracted from them. Therefore, this review intends to x-ray these variations, its effect on the structural properties of extracted CNPs and possible ways such limitations can be mitigated.
