In the present study, effects of chemical (ethanol, HCl and sulphuric acid) pretreatment on various dehulling parameters of flaxseed (cv. Garima) including yield, hull, hullability, extraction rate and embryo (dehulled flaxseed) recovery were studied. Pretreated flaxseed, at 3.1 to 3.6 % moisture range (p > 0.05) were dehulled for 60 s in a laboratory model rice polisher/dehulling machine at 2,000 rpm followed by aspiration (hull separation) using a laboratory model aspirator. The study revealed that chemical pre-dehulling treatment of flaxseed plays a significant role in the embryo recovery of flaxseed. Both ethanol and HCl pre-dehulling treatment enhanced but sulphuric acid pretreatment reduced the embryo recovery of flaxseed. Moreover, HCL and Sulphuric acid deteriorated the quality of hull obtained during dehulling, hence may not be considered for flaxseed dehulling. The study showed the maximum embryo recovery from ethanol pretreated flaxseed, hence ethanol pre-dehulling treatment with 2 h tempering time may be considered for effective flaxseed dehulling.
在本研究中，研究了化学预处理（乙醇、盐酸和硫酸）对亚麻籽（品种 Garima）各种脱壳参数的影响，包括产率、壳、可脱壳性、提取率和胚（脱壳亚麻籽）回收率。将预处理后的亚麻籽在 2,000rpm 的实验室模型大米抛光机/脱壳机中以 3.1 至 3.6%的水分范围（p>0.05）脱壳 60 秒，然后使用实验室模型吸气器（吸风）进行吸气（壳分离）。研究表明，亚麻籽的化学预脱壳处理在亚麻籽胚的回收中起着重要作用。乙醇和盐酸预处理均提高了亚麻籽的胚回收率，但硫酸预处理降低了亚麻籽的胚回收率。此外，盐酸和硫酸会降低脱壳过程中获得的壳的质量，因此可能不适合用于亚麻籽脱壳。研究表明，从乙醇预处理的亚麻籽中可以获得最大的胚回收率，因此，2 小时调温时间的乙醇预处理脱壳可能是一种有效的亚麻籽脱壳方法。
