Abstract

This study reports on the preparation of high-adsorptive V-type starch (HAVS) through the hydrolysis of normal maize starch using thermal-stable α-amylase in a 40 % (v/v) ethanol solution. The resulting HAVS was then utilized to produce powdered flaxseed oil (FO) via dry heating. HAVS prepared in 40 % ethanol solution with 0.250 % thermal-stable α-amylase (w/w, dry matter basis) at 90°C for 90 min, yielding an oil adsorption rate of 308.15 %. Single-factor experiments determined the optimal conditions for powdered FO production as an oil addition ratio of 130 % (v/w), a heating temperature of 80°C and a heating time of 10 min. In comparison, the maximum adsorption capacity of commercial porous starch (CPS) for FO under identical heating conditions was only 80 % (v/w). XRD, DSC and FTIR analysis confirmed that powdering of FO using HAVS as a carrier was through physical adsorption. Laser particle size analysis revealed that the powdered FO prepared with HAVS exhibited a more uniform particle size distribution compared to CPS. Storage stability tests demonstrated that HAVS significantly delayed the oxidative rancidity of FO, offering substantial protection. These findings suggest that HAVS is an effective carrier for FO, enhancing its stability and potentially its application in various industries.

高吸附性v型淀粉的制备及其在亚麻籽油粉末状生产中的应用

本文报道了在40% （v/v）乙醇溶液中，利用热稳定α-淀粉酶水解普通玉米淀粉制备高吸附性v型淀粉（HAVS）的研究。然后利用所得的HAVS通过干热生产粉末状亚麻籽油（FO）。HAVS在含0.250%热稳定α-淀粉酶（w/w，干物质基）的40%乙醇溶液中，90℃，90 min下制备，油吸附率为308.15%。单因素实验确定了粉状FO生产的最佳工艺条件为油的添加比为130% (v/w)，加热温度为80℃，加热时间为10 min。相比之下，在相同的加热条件下，商品多孔淀粉（CPS）对FO的最大吸附量仅为80% （v/w）。XRD、DSC和FTIR分析证实，以HAVS为载体的FO粉化是通过物理吸附完成的。激光粒度分析表明，与CPS相比，HAVS制备的粉末FO具有更均匀的粒度分布。储存稳定性试验表明，HAVS显著延缓了鱼油的氧化酸败，提供了实质性的保护。这些结果表明，HAVS是FO的有效载体，增强了其稳定性，具有在各行业应用的潜力。
