加工方式对绿豆蛋白亚基和功能性质的影响

绿豆中蛋白质含量高,氨基酸种类丰富,是一种具有较强加工适用性的优质蛋白质资源。本实验以绿豆为材料,对绿豆进行蒸制、煮制两种不同热处理,用碱提酸沉法提取绿豆蛋白,并对其进行结构和功能性质的测定。结果表明：随着热处理时间的延长,蒸制和煮制的绿豆蛋白中大分子蛋白亚基条带灰度均变浅,即大分子质量蛋白含量均减少,分子质量为57.5 kDa的8S球蛋白亚基条带逐渐消失。两种处理相比,煮制绿豆蛋白增加了一条分子质量为35.4 kDa的条带。两种处理绿豆蛋白的持水性、持油性、乳化性、乳化稳定性均随处理时间延长不断提高,且蒸制绿豆蛋白优于煮制;而起泡性、泡沫稳定性、溶解性随处理时间延长呈先上升后下降的趋势,在20～25 min时性能最佳,蒸制绿豆蛋白的性能较好,起泡性、泡沫稳定性、溶解度分别为25.6%、77.1%、13.6%。本研究为绿豆蛋白的改性提供理论依据,对提高绿豆蛋白在食品行业中的应用以及绿豆产品的精深加工具有参考意义。

Does Processing have a Considerable Effect on the Nutritional and Functional Properties of Mung Bean (Vigna Radiata)?

Mung bean is an important grain legume which is rich in nutrients and other bioactive compounds with many beneficial physiological effects. However, the effect of processing on properties of mung bean has not been widely studied in Sri Lanka. In the current study, effect of processing (boiling and sprouting) on some nutritional and functional properties of mung bean was investigated in comparison with raw mung bean. Mung bean seeds (Vigna radiata), varity MI6 were obtained from the Government Seed Center, Dambulla, Sri Lanka. Proximate composition, gross energy, insoluble dietary fibre (IDF) and soluble dietary fibre (SDF) contents,total phenolic content (TPC), total flavonoid content (TFC), α-amylase inhibition capacity, DPPH and ABTS scavenging activities were determined. Crude Protein (CP) content of boiled mung bean was significantly (p<0.05) lower than that of raw mung bean while it was significantly (p<0.05) higher in sprouted mung bean than raw mung bean. Crude fat content (CF) was significantly (p< 0.05) lower in sprouted mung bean when compared to raw mung bean. IDF contents in raw mung bean was significantly (p<0.05) higher than that in sprouted and boiled mung bean whereas, SDF content in boiled and sprouted mung bean were significantly (p<0.05) higher than that in raw mung bean.processing significantly (p<0.05) reduced antioxidant activity and total phenol content compared to raw mung bean. However, flavonoids could only be detected in sprouted mung bean. Further, α-amylase inhibition in sprouted mung bean was significantly (p<0.05) higher than that in boiled mung bean. In conclusion, processing (boiling and sprouting) influences the CP content, CF content, dietary fibre content, antioxidant capacity, α-amylase inhibition and fermentation ability in mung bean.     

Hypolipidemic and hypoglycemic potential of raw,boiled, and sprouted mung beans (Vigna radiata L. Wilczek) in rats

This study was carried out to investigate the hypolipidemic and hypoglycemic potential of raw, boiled, and sprouted mung beans in rats. Oven dried mung bean powders; raw, sprouted, and boiled were included at 30% level in the diet of seven weeks old male Wistar rats maintained for 5 weeks on high (0.5%) cholesterol diet in comparison with control diet. Low serum glucose and triglyceride concentrations (p < .05) in raw and processed mung bean diets fed rats were supported by low serum insulin level in both raw mung bean diet and boiled mung bean diet fed rats. Hypoglycemic effect in sprouted mung bean fed rats was supported by higher α‐amylase inhibitory activity and α‐glucosidase inhibitory activity of sprouted mung beans. Increase in serum non‐HDL cholesterol concentration and decrease in HDL cholesterol concentration caused by high cholesterol diet were modulated (p < .05) by both boiled and sprouted mung bean diets.

Practical applications

Mung bean is a green legume rich in protein, fiber, antioxidants, and phytonutrients. Hypocholesterolemic and hypoglycemic potential of raw mung beans have been shown previously. It is well known that cooking and processing modulate nutritional and biochemical parameters of foods. However, very limited information is available on the effect of processing on functional properties of legumes. Results of this study showed that boiling and sprouting improved the soluble fiber content and hypocholesterolemic potential of mung beans. Thus, the processed mung beans may be more suitable for developing food supplements for patients with hypercholesterolemia.
