为研究橄榄菜贮藏过程中的品质变化,对橄榄菜水分含量、食盐含量、糖分含量、脂肪含量、脂肪酸含量、亚硝酸盐含量、反式脂肪酸含量、丙烯酰胺含量进行检测;采用气相色谱-离子迁移谱(gas chromatography-ionmobility spectrometry,GC-I... 详细信息

为研究橄榄菜贮藏过程中的品质变化,对橄榄菜水分含量、食盐含量、糖分含量、脂肪含量、脂肪酸含量、亚硝酸盐含量、反式脂肪酸含量、丙烯酰胺含量进行检测;采用气相色谱-离子迁移谱(gas chromatography-ionmobility spectrometry,GC-IMS)技术检测橄榄菜挥发性物。结果显示,在25℃贮藏条件下,水分含量为(2.04±0.04)~(2.33±0.05)g/100 g,食盐含量为(3.10±0.08)%~(4.41±0.03)%,糖分含量为(0.17±0.00)%~(1.10±0.02)%,脂肪含量为(33.70±0.35)%~(46.20±0.37)%,理化指标的变化对橄榄菜品质的影响较小。不饱和脂肪酸含量随贮藏时间的延长而增加,饱和脂肪酸含量随贮藏时间的延长而下降,脂肪酸与挥发性物质具有一定的相关性;总反式脂肪酸含量随贮藏时间的延长而下降;亚硝酸盐含量先升高后降低,贮藏21 d时达到“亚硝峰”23 mg/kg,已超过GB 2762—2017《食品安全国家标准食品中污染物限量》中规定的亚硝酸盐含量指标,21 d后,亚硝酸盐含量逐渐下降;橄榄菜在贮藏过程中未检出丙烯酰胺(<0.005%);橄榄菜在25℃条件下储存35 d品质良好。

Ltd. Guangzhou China

Juice drinks are an important commercialization alternative for lychee, a tropical and subtropical fruit. Although the lychee juice content is important when assessing the quality of a drink, there are no published methods to determine it, particularly simple ones for the routine inspection of juice drinks. Lychee juice drinks contain ingredients with buffering capacity including proteins and ions such as phosphate, citrate, lactate, carbonate, acetate and propionate. The relationship between their buffering capacity and lychee juice content was studied. Citric acid was added to pure lychee dilutions in distilled water containing 100%, 90%, 80%, 70%, 60%, 50%, 40%, 30%, 20% and 10% lychee juice. The pH of the dilutions was measured to obtain a linear model for the molar H+ concentration as a function of the added citric acid (g/L) amount LC = (BC-494.2)/12,031, where LC was the lychee juice content and BC was defined as the juice buffering coefficient.

竹笋肉质鲜嫩、清脆爽甜,是一种深受消费者喜爱的纯天然绿色健康食品。竹笋含有丰富的多糖、膳食纤维、黄酮和生物碱等生物活性物质,具有抗氧化、降血糖等功效。但随着竹笋加工业的不断发展,竹笋加工过程会产生大量笋头、笋壳等副产物,这些副产物往往被直接丢弃、燃烧或用作畜禽饲料,利用率较低,造成极大浪费,也对生态环境带来一定危害。这些副产物中同样含有较多生物活性物质,如何提高竹笋副产物的利用率逐渐成为竹笋产业迫切解决的问题。因此,对竹笋加工副产物中的天然活性物质(如多糖、膳食纤维、黄酮和生物碱等)的研究现状进行综述,总结了天然活性物质的提取方法、结构和活性作用与机制,以期为竹笋加工副产物活性物质的有效利用提供一定理论支撑。

The antioxidant properties and phenolic content of extracts of mulberry leaves obtained using aqueous mixtures of ethanol, methanol and acetone were determined. Both alkaline hydrolysis and acid hydrolysis were used to extract bound *** was used todeterminethe profile of the extracted phenolics. Threeexperimental assays, Fe3+reducing antioxidant power（FRAP）, ABTS and DPPH radical scavenging activity,were used to characterizetheantioxidant activity of the extracts. Acetone proved to be the most efficient solvent for extraction of free phenolics from mulberry leaves and the acetone extract had the highest antioxidant capacity. Alkaline hydrolysis was found to bethe best method for extracting bound phenolics and provided an extract with better antioxidant properties than acid hydrolysis.
