Complexation of V-type lotus seed starch and butyric acid: Structure and in vitro digestion SCIE

Abstract :

Butyric acid (BA), a short-chain fatty acid, significantly impacts gut health but is rarely incorporated as a guest molecule in starch-based products. Owing to their hydrophobic helical cavities, V-type starches can form inclusion complexes (ICs) with BA via hydrophobic interactions. In the current work, V-type lotus seed starches (VLS) were used in complexation with BA, and the structure and in vitro digestion of V-type lotus seed starchbutyric acid complexes (VLS-BAcs) as influenced by preultrasonication were investigated. The results showed that at the suitable ultrasonic power (similar to 360 W), 28.4% of the additional BA was complexed with preformed VLS. The IC formation significantly increased the crystallinity of starches and retarded amylose retrogradation. Highly crystallized VLS-BAcs exhibited strong thermal stability and hydrophobicity and displayed bound waterdominated structures. Moreover, VLS-BAcs formed at 360 W had a 12.4% higher RS proportion than their untreated counterparts. These obtained findings would provide valuable knowledge on the properties of VLS-BAcs modulated by ultrasound pretreatment and reveal its potential as a novel prebiotic for increasing BA concentration in the gut.

Abstract :

A method for the rapid simultaneous determination of limonin and nomilin in Kumquat by ultra performance liquid chromatography (UPLC) was developed. The limonin and nomilin in the samples were first extracted with methylene chloride by sonication. The analyses were performed on UPLC with an ACQUITY UPLCTM BEH C18 column (2.1 mm×100 mm, 1.7 μm), using acetonitrile-water (45:55, V/V) as the mobile phase at a flow rate of 0.3 mL/min. The column temperature is measured 35°C, with a detection wavelength of 215 nm. The two compounds were effectively separated by gadient elution and detected by PDA in 3 minutes. The Calibration curve were good linear in the range of 1~1780 μg/mL for limonin and 1~1720 μg/mL for nomilin, the correlation coefficient were both 0.9999. The limits of de-tection (LOD) were 1.65 μg/g and 1.28 μg/g. The additon recoveries were 97.19%~100.06% and 95.35%~99.83%, respectively. The relative standard deviations were less than 5%. The result indicated that the method is rapid, sensitive, convenient, accurate and may be used for determination of limonin and nomilin in kumquat.

莲子淀粉品质对莲子汁流变特性和保质期影响的研究 CSCD PKU
期刊论文 | 2005 , (12) , 167-170 | 农业工程学报
Abstract&Keyword Cite

Abstract :

淀粉品质是影响淀粉类食品品质的主要因素,优选低含量直链淀粉的莲子为原料是确保莲子产品品质的关键。本研究收集了中国具有代表性的22个野生及栽培莲子品种,并测定各品种直链淀粉含量(AC),按AC梯度从中选择7个莲子品种为原料分别制作莲子汁,研究莲子汁的流变特性和贮存过程中淀粉返生所致的流变性质变化,利用逐步回归法,建立莲子汁返生沉淀量与直链淀粉含量、贮存时间之间的数学模型。结果表明:莲子直链淀粉含量品种间差异较大,莲子汁为假塑性流体,淀粉在返生过程中黏度呈下降趋势,直链淀粉含量越高,黏度在贮存初期下降越快。莲子汁返生沉淀量与直链淀粉含量、贮存时间之间的数学模型为:Y=0.5107exp(0.020T-7.562×10-5T2+9.955×10-8T3+0.05C-0.001C2),该模型为莲子汁保质期预测和莲子优质育种目标提供理论依据,同时对淀粉质食品深加工开发也具有重要的参考价值。
