Octenylsuccination of sago starch and investigation of the effect of calcium chloride and ferulic acid on physicochemical and functional properties of the modified starch film

Abstract

Sago starch was esterified with octenyl succinic anhydride (OSA). Physicochemical and functional properties of obtained starch derivative were investigated. Then, film from OSA‐modified starch was prepared to investigate the effect of starch modification on the film characteristics. Calcium chloride and ferulic acid was also added to modified starch solution to improve film characteristics. Modification of starch was confirmed according to Fourier transformation infrared spectrum. OSA‐modified starch had improved functional properties of starch paste as its water adsorption, solubility in water, emulsifying activity, and clarity was increased. The result of scanning electron microscopy images and X‐ray diffraction spectra showed that modification of sago starch with OSA destroyed the granular structure of starch. Solubility in water, water adsorption, water vapor permeability (WVP), elongation at break, transparency, and air‐water contact angle of the starch film increased by starch modification. However, water adsorption and WVP of modified film containing calcium chloride and ferulic acid decreased. Practical applications Modification of starch is suggested to improve its physicochemical and functional properties. In this work, sago starch was modified with OSA. Results showed that chemical modification of sago starch with OSA improved functional properties of native starch. On the contrary, extensibility and transparency of the film prepared with OSA‐modified starch was more than the native starch film. The information will be useful for the improvement of the food product properties.

Inverse vulcanization of octenyl succinate-modified corn starch as a route to biopolymer–sulfur composites

“…Olefination with OSA is also well-precedented to give a product with limited change in crystallinity upon functionalization. 55 In our previous work, we have noted that retention of biopolymer crystallinity is a potential contributing factor in compatibilizing sulfur and biopolymer comonomers as well as for imbuing strength to the resultant cellulose-sulfur composites. 3,21 The incorporation of hydrophobic alkyl chains should also improve miscibility/ compatibilization with sulfur for more facile reaction than has been observed in some cellulose-sulfur systems.…”

Recent advances in starch‐based films toward food packaging applications: Physicochemical, mechanical, and functional properties

“…Most starches are predominantly amylopectin (waxy corn starch can be up to 100% amylopectin) although some sources, such as high amylose corn starch, can have upward of 70% amylose (Lu et al, 2019). In general, it has been observed that higher percentages of amylose lead to more rigid films as denoted by a higher TS and EM and a simultaneous decrease in EAB as a result of an increased crystallinity (Cano, Jimenez, Chafer, Gonzalez, Dilute alkaline steeping (Gani et al, 2017;Van Hung et al, 2016;Ziegler et al, 2017) Potato 390 Mt Wet milling (Bergthaller, 2004;Bertoft & Blennow, 2016;Nawaz et al, 2020;Singh et al, 2018) Cassava root (Gous & Fox, 2017;Rittenauer, Kolesnik, Gastl, & Becker, 2016;You & Izydorczyk, 2002;Yu et al, 2017) Oat (Chu, 2014;Xu et al, 2017) Sago >90 kt Milling followed by wet sieving (Arshad, Zaman, Rawi, & Sarbini, 2018;Ehara, Toyoda, & Johnson, 2018;Karim, Tie, Manan, & Zaidul, 2008;Naseri et al, 2019) Note: Estimated yearly production in Indonesia, the largest producer of sago.…”

“…Other additives that have been implemented include CaCl 2 and ferulic acid, which were incorporated into modified sago starch (0.7 and 0.05 wt%, respectively) due to their ability to plasticize starch (Naseri et al., 2019). As plasticizers, these agents caused a slight reduction in TS and an increase in EAB (Table 2, entry 38).…”

“…Most of the research on starch has been conducted with starch from various cereal grains, potatoes, and cassava because of their ubiquitous production around the world. However, more niche agricultural products like sago, quinoa, mung beans, taro, and even black pepper have also gained attention recently (Abdorreza & Abd Karim, 2013;Arezoo, Mohammadreza, Maryam, & Abdorreza, 2020;Asria, 2016;Chanjarujit, Hongsprabhas, & Chaiseri, 2018;Gutierrez, 2017;Gutierrez & Gonzalez, 2016;Kittipongpatana et al, 2006;Naseri, Shekarchizadeh, & Kadivar, 2019;Zhu, Mojel, & Li, 2017). A recent publication analyzed various pumpkin, lentil, and quinoa starches and found that films prepared from these starches were comparable to potato starch films, emphasizing the potential to utilize a seemingly endless number of agricultural products to produce sustainable, starch-based films (Pajak, Przetaczek-Roznowska, & Juszczak, 2019).…”
