    摘要:

    研究乳鐵蛋白（LF）—多酚（表沒食子兒茶素沒食子酸酯（EGCG）、綠原酸（CA）,、沒食子酸（GA））共價復(fù)合物對β-胡蘿卜素乳狀液穩(wěn)定性的影響,。采用自由基接枝聚合法制備乳鐵蛋白—多酚共價復(fù)合物并進(jìn)行高效液相色譜檢測。以乳鐵蛋白—多酚共價復(fù)合物為乳化劑制備β-胡蘿卜素乳狀液,，通過加速分層和量化沉淀,、懸浮的方法快速測定乳狀液的穩(wěn)定性；通過光照和不同溫度（25℃,、37℃和55℃）條件下的貯藏實(shí)驗(yàn),，測定乳狀液中β-胡蘿卜素的化學(xué)穩(wěn)定性。結(jié)果表明,，乳鐵蛋白經(jīng)多酚修飾后,，色譜峰保留時間縮短，親水性增加,。乳鐵蛋白與多酚生成的共價復(fù)合物可以提高乳狀液的穩(wěn)定性,，同時可以抑制水包油乳狀液中β-胡蘿卜素的降解，提高β-胡蘿卜素的化學(xué)穩(wěn)定性,。3種共價復(fù)合物中,，LF—CA共價復(fù)合物對β-胡蘿卜素乳狀液具有最好的穩(wěn)定效果。

    Abstract:

    The objective of the study was to investigate the effects of lactoferrin-polyphenol conjugates on the stability of β-carotene emulsions. Conjugates of lactoferrin with polyphenol ((-)-epigallocatechin-3-gallate(EGCG), chlorogenic acid and gallic acid) were achieved by a free radical grafting procedure. The hydrophilic/hydrophobic characteristics of latoferrin and lactoferrin-polyphenol conjugates were studied by reverse-phase HPLC. Lactoferrin-polyphenol conjugates were used as emulsifiers to prepare β-carotene emulsions, and the stability of β-carotene emulsions was characterized by transmission profiles through using novel centrifugal sedimentation and β-carotene degradation in the emulsion during storage. The results implied that hydrophilicity of lactoferrin was increased after modified by polyphenol; compared with those stabilized by lactoferrin alone, the emulsions stabilized by lactoferrin-polyphenol conjugates were able to improve the stability of β-carotene emulsions and inhibit the deterioration of β-carotene in oil-in-water emulsions, and lactoferrin-chlorogenic acid conjugate was the best emulsifier among the lactoferrin-EGCG, lactoferrin-chlorogenic acid and lactoferrin-gallic acid conjugates. 
