Physical, Physicochemical, Mechanical, and Sensory Properties of Bioplastics from Phosphate Acetylated Arenga Starches

Abstract

an alternative to plastic packaging due to their environmental friendliness and easy degradation. Therefore, there is an urgent need for bioplastics due to the rapid increase in the pace of plastic production and air pollution causing several health risks because of their toxic nature [Jain & Tiwari, 2015]. Bioplastics are, however, very suitable alternatives to improve the quality of life and maintain a pollution-free planet [Keziah et al., 2018]. It has been discovered that bioplastics made from native starch have poor physicochemical, mechanical, functional and sensory characteristics compared to those modifi ed chemically. According to Shindu & Khatkar [2018], those produced from modifi ed wheat starch are transparent, have greater tensile strength, and lower solubility compared to the native wheat starch. Moreover, edible fi lms of acetylated rice starch were also found to be stable to heat, have high elongation at break, and a rapid process of degradation [Collusi et al., 2017]. Meanwhile, the mechanical properties of bioplastics from tapioca starch modifi ed using acetic anhydride were observed to be superior over these of the native starch

Preparation of green film with improved physicochemical properties and enhanced antimicrobial activity using ingredients from cassava peel, bamboo leaf and rosemary leaf

“…The WVTR of the biofilms was determined based on the method designed by Rahim et al. (2020) as follows: the chamber (jar) with a diameter of 10 cm and a height of 12 cm was first adjusted to relative humidity of 75% by adding a solution of 50% NaCl (w/v).…”

Then an acrylic cup with a diameter of 3 cm and height of 1.6 cm was filled with 6 g silica gel, covered with the biofilm of size 6 cm  8 cm and placed in the moisturized chamber.…”

Application of modified starch on glass bioplastic based on carrageenan from Eucheuma cottonii on mechanic and biodegradation properties

“…After being homogeneous, 5 mL of sorbitol was added and stirred for 2 minutes while maintaining the suspension temperature at 60°C. The suspension was molded in a glass mold, allowed to stand at room temperature for 2 hours and then in an oven at 50°C for 24 hours [19].…”

“…So, it is necessary to solve problems that can reduce the use of plastic cups, namely by formulating materials that can decompose naturally as materials for glass bioplastics. Bioplastic is an alternative to plastic packaging that can be made from natural materials that can be widely used because it is environmentally friendly and easily degraded [6]. One of the characteristics of bioplastics or plastics is their resistance to water.…”

Ethno‐pharmacological and industrial attributes on the underutilized Arenga species in India

“…Many researchers have been involved in search of alternatives to plastic or better to say biodegradable plastics. It has been concluded that native arenga starch (NAS) obtained from A. pinnata can be utilized to produce bioplastics (Rahim et al, 2020). However, it has also been concluded that bioplastics manufactured from NAS have poor mechanical, physicochemical, functional, and sensory properties.…”
