To improve the bioavailability of whey protein hydrolysates, the effects of different ultrasonic power treatments (100, 200, 300, 400 W) on the structural characteristics of whey protein were investigated, along with their effect on the degree of hydrolysis, peptide content, and α-glucosidase inhibitory activity of the hydrolysates. The results demonstrated that moderate ultrasound treatment expanded the whey protein structure. Compared to the untreated sample, at 300 W for 25 min, the intrinsic fluorescence intensity reached its peak, and the average particle size decreased by 62% (P<0.05). Additionally, surface hydrophobicity and free sulfhydryl content increased by 35% and 36%, respectively. Secondary structure analysis revealed a reduction in α-helix (42%) and β-sheet (20%) content, while β-turn and random coil increased by 26% and 77% (P<0.05), respectively. Scanning electron microscopy (SEM) further confirmed structural changes, showed a transition from large, rough-edged sheets to smaller, smooth-edged fragments. Lactiplantibacillus plantarum C11 was used to ferment whey protein after ultrasonic treatment. Compared with non-ultrasonic fermented whey protein, the degree of hydrolysis, peptide content and α-glucosidase inhibition rate were increased by 26%, 15% and 32% (P<0.05), respectively. Moderate ultrasonic pretreatment can enhance the α-glucosidase inhibitory activity of whey protein fermentation products, which provides a new strategy for synergistic preparation of whey protein bioactive peptides.

为了提高乳清蛋白水解产物的生物利用度,探究不同超声功率处理(100、200、300、400 W)对乳清蛋白结构特性及其发酵产物水解度、肽含量和α-葡萄糖苷酶抑制活性的影响。结果表明,适度的超声可以使乳清蛋白结构展开,与未超声相比,300 W、25 min的超声条件使乳清蛋白的内源荧光强度达到最大值,平均粒径降低了62%(P<0.05),表面疏水性及游离巯基数量分别提高了35%、36%,α-螺旋、β-折叠分别降低了42%和20%,β-转角、无规则卷曲分别提高了26%和77%(P<0.05);扫描电镜显示乳清蛋白结构从边缘粗糙的大体积片状结构变为边缘光滑的碎片状结构。利用Lactiplantibacillus plantarum C11对超声处理后乳清蛋白进行发酵,与未超声发酵乳清蛋白相比,水解度,肽含量以及α-葡萄糖苷酶抑制率分别提高了26%、15%和32%(P<0.05)。适度的超声预处理能够增强乳清蛋白发酵产物的α-葡萄糖苷酶抑制活性,这为增效制备乳清蛋白生物活性肽提供了新的策略。

为了提高乳清蛋白水解产物的生物利用度,探究不同超声功率处理(100、200、300、400 W)对乳清蛋白结构特性及其发酵产物水解度、肽含量和α-葡萄糖苷酶抑制活性的影响。结果表明,适度的超声可以使乳清蛋白结构展开,与未超声相比,300 W、25 min的超声条件使乳清蛋白的内源荧光强度达到最大值,平均粒径降低了62%(P<0.05),表面疏水性及游离巯基数量分别提高了35%、36%,α-螺旋、β-折叠分别降低了42%和20%,β-转角、无规则卷曲分别提高了26%和77%(P<0.05);扫描电镜显示乳清蛋白结构从边缘粗糙的大体积片状结构变为边缘光滑的碎片状结构。利用Lactiplantibacillus plantarum C11对超声处理后乳清蛋白进行发酵,与未超声发酵乳清蛋白相比,水解度,肽含量以及α-葡萄糖苷酶抑制率分别提高了26%、15%和32%(P<0.05)。适度的超声预处理能够增强乳清蛋白发酵产物的α-葡萄糖苷酶抑制活性,这为增效制备乳清蛋白生物活性肽提供了新的策略。

To improve the bioavailability of whey protein hydrolysates, the effects of different ultrasonic power treatments (100, 200, 300, 400 W) on the structural characteristics of whey protein were investigated, along with their effect on the degree of hydrolysis, peptide content, and α-glucosidase inhibitory activity of the hydrolysates. The results demonstrated that moderate ultrasound treatment expanded the whey protein structure. Compared to the untreated sample, at 300 W for 25 min, the intrinsic fluorescence intensity reached its peak, and the average particle size decreased by 62% (P<0.05). Additionally, surface hydrophobicity and free sulfhydryl content increased by 35% and 36%, respectively. Secondary structure analysis revealed a reduction in α-helix (42%) and β-sheet (20%) content, while β-turn and random coil increased by 26% and 77% (P<0.05), respectively. Scanning electron microscopy (SEM) further confirmed structural changes, showed a transition from large, rough-edged sheets to smaller, smooth-edged fragments. Lactiplantibacillus plantarum C11 was used to ferment whey protein after ultrasonic treatment. Compared with non-ultrasonic fermented whey protein, the degree of hydrolysis, peptide content and α-glucosidase inhibition rate were increased by 26%, 15% and 32% (P<0.05), respectively. Moderate ultrasonic pretreatment can enhance the α-glucosidase inhibitory activity of whey protein fermentation products, which provides a new strategy for synergistic preparation of whey protein bioactive peptides.

糖尿病在当代社会已经严重影响到人类健康,需要受到全面重视并采取措施进行预防和治疗[1]。预计到2045年,受到糖尿病影响的人数将达到7.83亿[2]。α-葡萄糖苷酶是一种存在于人体小肠上皮的水解酶,能对α-(1,4)-糖苷键进行特异性水解,释放出人体易于吸收的葡萄糖,引起血糖上升[3]。抑制α-葡萄糖苷酶活性可明显降低碳水化合物的消化与吸收,有效调节血糖水平的变化,成为治疗糖尿病的重要方法。目前市面上具有α-葡萄糖苷酶抑制活性的药物主要包括阿卡波糖、伏格列波糖和米格列醇等,这类药物会带来严重的腹泻,呕吐等胃肠道副作用[4−5],因此从天然来源中寻找经济效益高且副作用小的降糖成分受到了广泛关注。
乳清蛋白作为公认的优质蛋白来源,其必需氨基酸组成均衡且生物利用率高,通过可控水解可释放具有α-葡萄糖苷酶抑制活性[6]、抗氧化活性[7]等功能的生物活性肽。但乳清蛋白致密的三维空间结构制约其酶解效率。超声技术作为一种新兴物理改性方法,通过空化效应引发的局部高压冲击波及剪切效应,可有效解聚乳清蛋白的致密结构[8]。目前对于超声波改性蛋白主要集中于理化性质及功能特性的研究[9],对于超声预处理后发酵乳清蛋白增效制备生物活性肽的相关研究较少。因此本研究用不同超声功率预处理乳清蛋白,通过测定粒径、电位、表面疏水性等相关理化性质观察乳清蛋白结构的变化;对超声后的乳清蛋白进行发酵,测定发酵产物的水解度,肽含量和α-葡萄糖苷酶抑制活性,探究超声预处理对乳清蛋白发酵产物水解情况的影响,为乳清蛋白高效制备生物活性肽提供理论支持。

所有实验进行三次测定,数据以平均值±标准差的形式表示;使用IBM SPSS Statistics 24的ANOVA方差分析和Duncan多重检验对实验数据进行统计分析,P<0.05时表示数据之间存在显著性差异,使用 Origin 2024软件进行图形绘制。
蛋白质的粒径大小与其功能属性密切相关。不同超声功率对乳清蛋白粒径的影响如图1所示。未超声的乳清蛋白的平均粒径为591.2 nm,经过不同超声功率处理的乳清蛋白的平均粒径均显著低于未超声组(P<0.05),超声产生的剪切力和湍流力可以破坏乳清蛋白的非共价键,破坏蛋白的致密结构,使乳清蛋白解聚,显著降低乳清蛋白的粒径[18]。随着超声功率增加,乳清蛋白的平均粒径先降低后增加(P<0.05),在300 W达到最低,为226.5 nm,与对照相比降低了62%(P<0.05)。400 W时粒径又增加到257.9 nm,这可能是由于过度超声引起蛋白质分子的运动加速,增加分子间的碰撞,促进了蛋白质分子聚集的产生,这一结果与Jambrak等[10]对乳清蛋白的研究结果一致,结果表明,适当的超声能显著降低乳清蛋白分子的粒径。
粒子的表面电荷不仅在其稳定性中起关键作用,还会诱导与其他粒子的相互作用[19]。乳清蛋白表面电位呈现负值,这主要归因于蛋白质表面暴露的氨基酸基团产生的负电荷,Zeta电位绝对值越大,说明蛋白分子表面静电斥力越大,蛋白质体系越稳定[20]。超声功率对乳清蛋白Zeta电位的影响如图2所示。未经超声处理的乳清蛋白的Zeta电位绝对值为29.4 mV,和对照组相比,不同条件超声处理的乳清蛋白的表面电位绝对值均显著增加(P<0.05)。超声功率为300 W,乳清蛋白的表面电位绝对值最大,为36.1 mV。表面电位绝对值的增加可能是超声产生的空化效应和机械效应,使乳清蛋白聚集解离,蛋白质构象发生变化,更多带负电荷的残基暴露在蛋白质表面[21]。与Shen等[19]研究结果一致,超声处理使乳清蛋白表面电位绝对值增加。
表面疏水性(H0)是指分子表面所带疏水残基的数量,可以反映蛋白分子表面疏水残基的暴露情况[22]。如图3所示,与未超声组相比,经超声诱导后乳清蛋白的表面疏水性显著提升(P<0.05),超声引发疏水残基从分子核心区向表面迁移,增加了乳清蛋白的表面疏水性。这与Yao等[23]的研究结果一致。在本研究中,超声时间一定,功率参数与蛋白质表面疏水基团分布呈现倒U型构效关系(P<0.05),在300 W 25 min时达到最高值,与未超声相比提高了35%。超声功率进一步增加使蛋白质再次发生聚集,疏水残基随之重新包覆在蛋白质中,造成疏水性降低[24]。Jiang等[25]发现高功率,长时间超声会使黑豆蛋白结构重新聚集,表面疏水性降低,本研究结果与之一致。
内源性荧光光谱主要用于表征氨基酸残基中着色基团的相互作用,所以可以通过表征内源荧光光谱观察蛋白质的三级结构变化。如图4所示,与未经过超声处理的乳清蛋白相比,超声处理乳清蛋白的荧光强度均明显增加,但是超声处理只引起了荧光强度的变化,并没有引起显著的红移或是蓝移。表明超声处理改变了乳清蛋白样品的色氨酸残基周围局部区域的构象。超声时间一定,荧光强度随着超声功率的增加呈现先增加后减少的趋势,在300 W 25 min达到最大值。超声处理使蛋白质内部更多的色氨酸残基暴露,荧光强度上升[26]。与300 W超声处理相比,荧光强度的下降可能是因为高强度,长时间超声使蛋白质结构重新发生变化,通过疏水相互作用使蛋白质的结构重新聚集,色氨酸被重新包裹在蛋白质内部,荧光强度下降。Jin等[27]报道,高强度的超声条件导致荞麦分离蛋白荧光强度下降,本研究结果与之相似。
游离巯基(RSH)是主要位于蛋白质分子表面的一类基团,可参与形成非共价键,对蛋白质的结构产生重要影响。超声对乳清蛋白游离巯基含量变化如图5所示。与对照相比,超声处理后乳清蛋白的游离巯基含量显著增加,并且随着超声功率的增加呈现先增加后下降的趋势(P<0.05),300 W 25 min时游离巯基含量最高,较对照组提高了36%(P<0.05)。这可能是由于适度的超声能够诱导蛋白质构象的解折叠,导致嵌入蛋白质分子内的游离巯基暴露出来。然而,过度的超声会导致蛋白质再次发生聚合,从而使暴露在外的巯基重新被埋藏到分子内部,或者形成二硫键进而导致游离巯基数量降低[28]。
通过傅里叶变换红外光谱可以对乳清蛋白官能团和二级结构的变化进行分析。结果如图6所示,乳清蛋白在4000~400 cm−1 范围内出现了一系列特征峰。不同超声条件处理的乳清蛋白溶液具有相似的FTIR曲线,说明超声处理并没有改变乳清蛋白的骨架结构[29]。在酰胺I带(1600~1700 cm−1)出现两个特征峰,且与未超声处理相比,除了400 W 25 min,其他组均出现轻微红移,可能与超声处理导致C=O的伸缩振动有关,可用来表征蛋白质二级结构(α-螺旋、β-折叠、β-转角、无规则卷曲)的变化[30]。
图7显示了经过去卷积分析,二阶导数拟合以及吸光度分析得出的不同超声功率处理乳清蛋白后,二级结构含量变化。与未经超声处理的乳清蛋白溶液相比,经过超声处理的乳清蛋白溶液的α-螺旋和β-折叠均显著降低(P<0.05),β-转角、无规则卷曲的含量显著增加(P<0.05)。在300 W 25min时,α-螺旋和β-折叠的含量最低为16%与27%,较对照分别降低了42%和20%,β-转角、无规则卷曲的含量最高,为30%和27%,与对照相比分别提高了26%和77%。造成这种结果是因为超声处理改变了蛋白质的二级结构,空化效应产生的高能量和机械力破坏了原有分子间的相互作用力,使乳清蛋白的二级结构展开,使α-螺旋和β-折叠转变为β-转角、无规则卷曲[31]。胡锦瑞等[32]也发现,超声预处理会引起绿豆蛋白的α-螺旋、β-折叠、β-转角和无规则卷曲含量的变化,同时超声辅助酶解处理组与单独酶解处理组相比,α-螺旋和β-折叠含量显著降低,β-转角和无规则卷曲含量显著增加。
图8显示了未经超声处理和超声处理的乳清蛋白的形态特征。超声处理使乳清蛋白微观结构发生了明显改变。未经处理的乳清蛋白边缘粗糙且呈较大体积的片层状,经过超声处理的乳清蛋白呈现不规则碎片状,且边缘光滑。同样值得注意的是,随着功率的增加,在400 W 25 min时,乳清蛋白的微观结构重新形成了较大的聚集体,这些结果与之前粒径变化结果一致。过度超声会使乳清蛋白的小分子重新聚集起来,促使乳清蛋白分子之间展开并暴露游离巯基和疏水基团相互作用形成更大的聚集体[28]。Zhu等[33]发现在600 W功率下,处理30 min的样品比处理15 min的样品形成的碎片更大,本文的结果与之类似。
图9和图10分别为超声预处理对乳清蛋白发酵产物水解度和肽含量的影响。结果表明,与仅超声乳清蛋白组相比,未超声发酵以及超声预处理发酵乳清蛋白均显著提高了其发酵产物的水解度与肽含量(P<0.05)。超声预处理乳清蛋白发酵产物的水解度为29.4%,较单一发酵提高了26%(P<0.05)。肽含量为4.1 mg/mL,相比于单一发酵提高了15%(P<0.05)。由于超声的机械作用破坏了蛋白质的非共价结合力,使乳清蛋白结构展开,更多水解位点暴露,菌株发酵产生的蛋白酶能更多与乳清蛋白的水解位点结合,蛋白酶可及性增加,使蛋白水解程度提高,肽含量增加。Pipaliya等[34]研究超声辅助酶解对脱脂小麦胚芽粕进行预处理,然后用枯草芽孢杆菌和安琪酵母进行发酵,使小麦胚芽粕肽含量得到提高,本研究结果与之类似。
图11为超声预处理对乳清蛋白发酵产物α-葡萄糖苷酶抑制率的变化。与单一超声相比,单一发酵以及超声结合发酵均显著提高了乳清蛋白发酵产物α-葡萄糖苷酶抑制率(P<0.05),超声预处理乳清蛋白发酵产物具有最高α-葡萄糖苷酶抑制率,为41.3%(P<0.05)。相比于单一发酵,乳清蛋白发酵产物提高了32%(P<0.05)。超声增加乳清蛋白疏水口袋的展开,先前的研究表明,疏水氨基酸的存在更有可能与α-葡萄糖苷酶活性口袋中的氨基酸形成氢键,对α-葡萄糖苷酶表现出更好的α-葡萄糖苷酶抑制活性[35]。超声可以改变蛋白质的结构,包括疏水基团的暴露、二级结构的重新分布以及微观结构的变化,这些结构的修饰可以暴露更多的水解位点,提高酶的可及性[36]。因此推测超声处理后α-葡萄糖苷酶抑制活性的上升是蛋白分子的结构修饰和解折叠导致某些特定氨基酸的暴露以及分子间相互作用发生变化引起的蛋白质水解作用增加引起的。
本研究探讨了不同功率超声预处理对乳清蛋白结构特性及其发酵产物水解度、肽含量以及α-葡萄糖苷酶抑制活性的影响,通过测定不同超声功率处理后乳清蛋白的相关理化性质,发现适当超声处理能改变乳清蛋白二级与三级结构,在300 W、25 min时,乳清蛋白结构得到显著改善,粒径最小,荧光强度达到最大值,表面疏水性及游离巯基数量较对照相比分别提高35%、36%;α-螺旋、β-折叠较对照分别降低了42%和20%,β-转角、无规则卷曲与对照相比分别提高了26%和77%。在此条件下对乳清蛋白进行发酵,乳清蛋白发酵产物的水解度,肽含量以及α-葡萄糖苷酶抑制活性均显著上升(P<0.05),与单一发酵相比分别提高了26%、15%和32%。超声预处理发酵乳清蛋白提高了发酵产物的α-葡萄糖苷酶抑制活性,表明适度的超声预处理能够增强乳清蛋白发酵产物的α-葡萄糖苷酶抑制活性。但还应该对乳清蛋白发酵产物进行分离纯化以及体外和体内实验研究,以确定乳清蛋白发酵产物中生物活性肽的具体降糖机制。
