在碳水化合物存在下热处理的美拉德反应中,安全性一直是一个不确定的问题。早期研究发现焦糖色素中含有5-羟甲基-2-糠醛,该物质有毒,应尽可能去除。研究了超滤法对焦糖色素溶液中5-羟甲基-2-糠醛的去除效果。结果表明,5-羟甲基-2-糠醛可以完全通过10 kDa截留膜过滤,同时保留液的布朗宁褐变强度明显增加。结果表明,超滤是降低焦糖色素中5-羟甲基-2-糠醛含量和提高焦糖色素布朗宁强度的有效手段,可用于生产更健康的焦糖色素。
Safety uncertain was always a problem related to the Maillard reaction in heat treatment at a presence of carbohydrate. Early researches have detected caramel color contains 5-hydroxymethyl-2-furaldehyde which is toxic and should be removed from caramel color as much as possible. In the present paper, the effects of ultrafiltration on reducing 5-hydroxymethyl-2-furaldehyde in caramel color solutions were investigated. Results showed that 5-hydroxymethyl-2-furaldehyde could be filtered through 10kDa cut-off membrane absolutely, while, the retentate's browning intensity was increased significantly. All data show that ultrafiltration is an effective means to reduce 5-hydroxymethyl-2-furaldehyde content and increase browning intensity of caramel color solutions, which might be used in producing healthier caramel colors.
