    摘要:

    以辛烯基琥珀酸淀粉酯為乳化劑，采用超聲波乳化的方法制備了姜油納米乳液，并探討了環(huán)境因素對其穩(wěn)定性的影響。通過單因素試驗和響應(yīng)面優(yōu)化試驗，確定以乳化性能良好的Purity Gum 2000（PG）和Hi Cap 100（HC）2種辛烯基琥珀酸淀粉酯進(jìn)行納米乳液制備。以PG為乳化劑時，最佳工藝參數(shù)為超聲功率430W，姜油質(zhì)量分?jǐn)?shù)9%，乳化劑質(zhì)量濃度0.1g/mL，所得納米乳液的平均粒徑為（148±4.23）nm。以HC為乳化劑時，最佳工藝參數(shù)為超聲功率410W，姜油質(zhì)量分?jǐn)?shù)9.2%，乳化劑質(zhì)量濃度0.125g/mL，所得納米乳液平均粒徑為（162±3.25）nm。PG和HC姜油納米乳液均具有良好的pH值、離子強(qiáng)度抵抗性。酸性環(huán)境有利于姜油納米乳液的穩(wěn)定性保持。Ca離子濃度變化對姜油納米乳液穩(wěn)定性的影響大于Na離子，PG姜油納米乳液對離子強(qiáng)度的抵抗能力大于HC姜油納米乳液。在姜油納米乳液中添加適量的麥芽糊精可以起到抗凍的作用，PG姜油納米乳液的抗凍性能優(yōu)于HC姜油納米乳液。

    Abstract:

    The method for the preparation of ginger oil nano-emulsions using ultrasonic emulsification with OSA starch Purity Gum 2000 (PG), Hi Cap 100 (HC) and C001（F）as emulsifier was studied. Then the stability of ginger oil nano-emulsions was also studied. Through single factor and response surface optimization experiment, OSA starch PG and HC were chosen as emulsifiers. The optimum parameters to prepare ginger oil nano-emulsion with PG as emulsifier were ultrasonic power 430W, ginger oil concentration 9% and PG concentration 0.1g/mL. The average particle size of PG ginger oil nano-emulsion was (148±4.23)nm. The optimum parameters to prepare ginger oil nano-emulsion with HC as emulsifier were ultrasonic power 410W, ginger oil concentration 9.2% and HC concentration 0.125g/mL. The average particle size of HC ginger oil nano-emulsion was (162±3.25)nm. The PG and HC ginger oil nano-emulsions both have good pH resistance ability. Acidic solution are better for ginger oil nano-emulsions to keep stable. Both of PG and HC ginger oil nano-emulsions also have good ionic resistance ability and the ability of PG ginger oil nano-emulsion is stronger than HC. The influence of Ca ion on stability of ginger oil nano-emulsions is greater than Na ion. The addition of malt dextrin can improve the freeze-thaw stability of PG and HC ginger oil nano-emulsions. PG ginger oil nano-emulsion shows better freeze-thaw stability than HC ginger oil nano-emulsion. This study contributes to the further application of ginger oil nano-emulsions in food industry.
