Abstract Carica papaya Linnaeus commonly known as papaya is widely grown in Malaysia as a herbaceous plant with phytochemicals for a variety of use, particularly in the medical field. The therapeutic medicinal way of treating dengue fever using papaya leave extract mainly involves consumption a raw concoction and is very distasteful. Therefore, a study was carried out to develop stable emulsion with an acceptable taste through a ternary phase diagram system (TPDS), which comprised virgin coconut oil (VCO), isolated whey protein (WPI) and Carica papaya leaves extract (CPLE). The TPDS was developed using Chemix Software version 3.6 to identify the existence of homogenous phase region. In the first phase, a total of 11 selected samples (named as A to K) with concentrations ranging from 20% to 30% (w/w) of WPI from the homogenous phase region were used to select the best emulsion selection. Sample I with a composition of 25, 30 and 45% (w/w) comprising VCO, WPI and CPLE was selected and considered as the best and stable emulsion. In the second phase, sample I (renamed as sample M) underwent an addition of + 2% (sample L) and reduction of −2% (sample N) VCO. Analysis was carried out such as emulsion stability test (creaming index), pH value, viscosity, color and storage stability (4, 28 and 45 °C). The control sample was CPLE without any VCO or WPI. Sensory evaluation was also conducted to handpick the best formulation favored by 30 panellists. The sensory evaluation was conducted on samples L, M, N and CPLE using 7-point hedonic scale for preference on color, viscosity, odor, bitterness and overall acceptance attributes. The results showed that centrifugation test exhibited a stable emulsion for all the three samples (p > 0.05) L, M and N. In fact, there were differences between all the samples (p

Carica papaya 叶提取物可食用 O/W 乳液的物理化学和感官接受度作为潜在的天然药物

摘要 Carica papaya Linnaeus 通常被称为木瓜，作为一种草本植物在马来西亚广泛种植，其植物化学物质具有多种用途，特别是在医疗领域。木瓜叶提取物治疗登革热的药用方法主要是食用生药，非常难吃。因此，进行了一项研究，以通过三元相图系统 (TPDS) 开发具有可接受味道的稳定乳液，其中包含初榨椰子油 (VCO)、分离的乳清蛋白 (WPI) 和番木瓜叶提取物 (CPLE)。TPDS 是使用 Chemix 软件 3.6 版开发的，用于识别同质相区域的存在。在第一阶段，共有 11 个选定的样品（命名为 A 至 K），其浓度范围为 20% 至 30% (w/w) 的均相区域的 WPI，用于选择最佳乳液选择。选择包含 VCO、WPI 和 CPLE 的组成为 25%、30% 和 45% (w/w) 的样品 I，并将其视为最佳且稳定的乳液。在第二阶段，样品 I（重命名为样品 M）经历了 +2%（样品 L）的添加和 -2%（样品 N）的 VCO 减少。进行了乳液稳定性测试（奶油化指数）、pH值、粘度、颜色和储存稳定性（4、28和45°C）等分析。对照样品是没有任何 VCO 或 WPI 的 CPLE。还进行了感官评估，以挑选出 30 位小组成员青睐的最佳配方。对样品 L、M、N 和 CPLE 使用 7 点享乐量表对颜色、粘度、气味、苦味和整体接受度属性的偏好。结果表明，离心试验对所有三个样品（p > 0.05）L、M 和 N 均表现出稳定的乳液。实际上，所有样品之间都存在差异（p
