Utilization of Uncaria gambir Roxb filtrate in the formation of bioactive edible films based on corn starch

Abstract

The objective of this research was to determine the effect of Uncaria gambir Roxb filtrate addition on functional edible films based on corn starch. This study used a Factorial Randomized Completely Design with two treatments and three replication for each treatment. The first factor was the concentration of Uncaria gambir Roxb filtrate (20%, 30%, 40%) and the second factor was the mixing separation method (filtering, centrifuge 1000 rpm, centrifuge 2000 rpm). The results showed that treatment of Uncaria gambir Roxb filtrate and the mixing separation method had significant effect on thickness, elongation percentage, water vapour transmission rate, antioxidant and antibacterial activities of edible film. The interaction of Uncaria gambir Roxb filtrate and the mixing separation method had significant effect on water vapour transmission rate. The best treatment based on edible film characteristics was 40% concentration of Uncaria gambir Roxb filtrate and the mixed separation method of 1000 rpm centrifugation.

Green biosynthesized Satureja rechingeri Jamzad-Ag/poly vinyl alcohol film: quality improvement of Oncorhynchus mykiss fillet during refrigerated storage

“…Thus, prolonging the storage time for fresh fish preservation is a critical measure in the processing (Zulkarneev et al, 2019). Due to some evidence over the silver escaping from nanocomposite and worries concerning the recycling of LDPE as a host for silver ion and biocompatibility; however, the researchers are interested in either the green-synthesis of nanocomposites by reducing the concentration of silver and other ions in the final products (Dehghanizade et al, 2018), which produced from natural substrates such as tea polyphenols and chitosan composite film (Peng et al, 2020), edible film from mammee apple, Mammea americana a well-known tropical fruit (Nascimento et al, 2020), starch based film loaded with Uncaria gambir (Santoso et al, 2019), yam/maize starch edible film with lemon plasticizer (Song et al, 2019) or the environment-friendly polymer-based compounds as a host for ions (Nwabor et al, 2020). The herbal-derived nanoparticles (NPs) such as Savory (S. rechingeri) extract with remarkable antimicrobial activities can be applied in various professions such as health care, food industries, biomedicine and engineering sciences.…”

Edible and Functionalized Films/Coatings—Performances and Perspectives

“…For all three types of starch, the reduction in gas exchange was found to be approximately 27%. Corn starch, with hydroxypropyl methylcellulose, Uncaria gambir extract, and glycerol were used as the main ingredients for edible film preparation [94]. To assess the influence of gambir extract to edible film parameters, an experimental design and statistical analysis were used.…”

Effect of gelatin based edible coatings on quality of surimi from pearl mullet (Alburnus tarichi,Güldenstädt, 1814) during cold storage

“…Whey protein, for example, may be used in formulation of edible films and/or coatings, leading to superior mechanical properties in the presence of oligosaccharides (Fernandes et al, 2020). Corn starch is another polymer that can be used in active edible films, mechanical properties of which are greatly affected by mixing method and the level of added active ingredients (Santoso et al, 2019). Processing waste of various food manufacturing processes, like potato peel waste, may find a place in formation of edible films and coatings (Othman et al, 2017).…”
