“…Different kinds of organic and inorganic acids, such as acetic, lactic, citric, and hydrochloric acids, can dissolve chitosan (Melro et al, 2021) and affect the mechanical properties of chitosan films (Nadarajah, 2005). Based on the studies, adding chitosan to agar film improves its mechanical properties by creating hydrogen bonds between agar and chitosan (Sinaga et al, 2020), resulting in modifying AC composite and increasing its tensile strength compared to agar film. Modifying ACF composite with citric acid increased the tensile strength of ACFA films.…”

“…As observed, adding chitosan to the agar film improves the AC film compared to the first one, indicating a similar result in the tensile strength (Figure 3a). Sinaga et al (2020) argued that the lowest elongation percentage is related to the agar film, and adding glycerol increases such a parameter from 0.2% to 9.8%. Based on the results, adding chitosan to agar/glycerol film increased the elongation percentage to about 19% (Sinaga et al, 2020).…”

“…However, to improve the mechanical and physical properties of agar, such as fragility and high permeability to water vapor, its combination with other polymers, plasticizers, and nanoparticles can be used (Saurabh et al, 2015; Wang et al, 2018). The previous studies showed that the combination of agar with chitosan improves its mechanical properties due to the hydrogen bond interactions between the amine group of chitosan and the hydroxyl group of agar (Sinaga et al, 2020).…”

Today, the approach of using biodegradable food coatings and films is developing because, in addition to maintaining and improving the chemical, organoleptic, and physical properties of food (Bykov et al., 2017;Kocira et al., 2021), the result of biological decomposition of these types of packaging are non-toxic compounds such as water, carbon dioxide, and mineral compounds (Siracusa et al., 2008).

Fruit leather is a food modification of semi-wet or dry processed fruit products in the form of thin sheets. Agar flour from seaweed Gracilaria sp. Can be used to improve the texture of fruit leather so that it is easy to consume. The aim of this research was to determine the role of agar powder from Gracilaria sp. in improving the texture of fruit leather and the influence on consumer preference value. The research method used is experimental laboratories. Making fruit leather using jackfruit then adding agar flour from Gracilaria sp. using control concentrations, 0.5%, 1%, 1.5%, and 2%. Testing of jackfruit fruit leather includes total sugar, water content, pH, ash content, texture and hedonic test. The results showed that the addition of Gracilaria sp agar powder had significant effect on all fruit leather parameters. The addition of 0.5% Gracilaria sp agar flour produced the best fruit leather.
