Barbary fig ( spp), called prickly pear, is a cultivated species belonging to family Cactaceae. It produces fruits one time per year during a short season. It is largely spreading in the Mediterranean countries. The aim of the study was to investigate the physicochemical and biochemical analysis of powder of prickly pear fruit peels of three Moroccan varieties (Aakria, Derbana, and Mles). . Both physicochemical analysis (humidity, water activity, Brix, ash content, pH, and total titratable acidity) and biochemical analysis (total carotenoid content, betalain content, total polyphenolic content, and ascorbic acid content) were effectuated according to protocols reported within the present research work.
Regarding the physiochemical analysis, the humidity of powder of prickly pear fruit peels ranged from 10.173 ± 0.002 to 15.27 ± 0.02%. The water activity (aw) ranged from 0.17 ± 0.002 to 0.336 ± 0.002. The values of Brix ranged from 68.67 ± 0.33 to 74.22 ± 0.51° Bx. pH values ranged from 5.41 ± 0.01 to 5.62 ± 0.01. The total titratable acidity values ranged from 0.644 ± 0.014 to 0.76 ± 0.007 g citric acid/100 g DM (dry matter). The ash content ranged from 1.02 ± 0.02 to 11.41 ± 0.03 g/100 g DM. Regarding the biochemical analysis, the total carotenoid content ranged from 5.14 ± 0.10 to 9.79 ± 0.06 mg/g of FM (Fresh matter). The total betalain content ranged from 2 ± 0.69 to 37.66 ± 2.65 mg/100 g of DM. The total polyphenolic content ranged from 1739.92 ± 13.69 to 2409.66 ± 43.65 mg gallic acid equivalent (GAE)/100 g of DM. The ascorbic content values ranged from 186.78 ± 13.23 to 294.04 ± 5.81 mg/100 g of DM.
The results showed an interesting richness of the investigated powder in pigments (betacyanins, indicaxanthins, and carotenoids) and nutritional compounds including sugar, proteins, and vitamins that make this powder interesting for being used as a dye in food.
巴贝多仙人果( spp),又称刺梨,是一种仙人掌科的栽培物种。它每年在短季节内产生一次果实。它主要分布在地中海国家。本研究的目的是研究三种摩洛哥品种(Aakria、Derbana 和 Mles)的仙人果果皮粉的物理化学和生物化学分析。根据本研究工作中报告的方案进行了物理化学分析(水分、水分活度、Brix、灰分含量、pH 值和总可滴定酸度)和生物化学分析(总类胡萝卜素含量、甜菜红素含量、总多酚含量和抗坏血酸含量)。
关于生理化学分析,仙人果果皮粉的水分含量在 10.173±0.002 至 15.27±0.02%之间。水分活度(aw)在 0.17±0.002 至 0.336±0.002 之间。Brix 值在 68.67±0.33 至 74.22±0.51°Bx 之间。pH 值在 5.41±0.01 至 5.62±0.01 之间。总可滴定酸度值在 0.644±0.014 至 0.76±0.007 g 柠檬酸/100 g DM(干物质)之间。灰分含量在 1.02±0.02 至 11.41±0.03 g/100 g DM 之间。关于生物化学分析,总类胡萝卜素含量在 5.14±0.10 至 9.79±0.06 mg/g FM(新鲜物质)之间。总甜菜红素含量在 2±0.69 至 37.66±2.65 mg/100 g DM 之间。总多酚含量在 1739.92±13.69 至 2409.66±43.65 mg 没食子酸当量(GAE)/100 g DM 之间。抗坏血酸含量值在 186.78±13.23 至 294.04±5.81 mg/100 g DM 之间。
结果表明,所研究的粉末在色素(甜菜红素、 indicaxanthins 和类胡萝卜素)和营养化合物(包括糖、蛋白质和维生素)方面具有丰富的含量,这使得该粉末作为食品染料具有很大的应用潜力。
