Aseptic processing is focused only fruit juices, but the processing of strengthful fruit, like fruit juice fortified with other beneficial herbs by tetrapack processing has not been attempted. The aim of the study to introduce a new form of orange juice with a good nutritional value.
Orange-Mint leaves juice was formulated using different addition percentages of mint leaves extract. The juice was aseptically processed, packed in glass bottles under sterilized environment and sterilized at 70°C for 15min then storage at 5°C for 3 months. All of the properties of juice "physicochemical, nutritional values, microbiological and sensory" was determined.
The results showed that there was no difference in pH, total soluble solids, ash, and total acidity in all samples moreover, the orange juice with 15% of mint leaves extract recorded the best values of sensory evaluation, on the other hand, it was recorded lower values of vitamin C and total phenolic compound than fresh or pasteurized orange juice because of increasing in addition % of mint leaves extract to orange juice. The sensory properties of juice samples were not remarkable any changes during storage. The results indicated that the juice had a good acceptability up to 3 months of storage at 5°C.
Now, the consumer is interested with nutritional and healthy foods, because functional foods reduce the health problems, as described in various patents. So, the Orange-Mint leaves blended juice will be a good option for the consumer.
无菌加工仅针对果汁，但尚未尝试通过利乐包装工艺对强化水果进行加工，例如添加其他有益草药的强化果汁。本研究的目的是推出一种具有良好营养价值的新型橙汁。
使用不同添加比例的薄荷叶提取物配制橙 - 薄荷叶汁。该果汁经过无菌加工，在无菌环境下装入玻璃瓶中，于70°C灭菌15分钟，然后在5°C下储存3个月。测定了果汁的所有性质“理化性质、营养价值、微生物学和感官性质”。
结果表明，所有样品的pH值、总可溶性固形物、灰分和总酸度均无差异。此外，添加15%薄荷叶提取物的橙汁在感官评价中表现最佳。另一方面，由于薄荷叶提取物在橙汁中的添加比例增加，其维生素C和总酚化合物的含量低于新鲜或巴氏杀菌橙汁。在储存期间，果汁样品的感官性质没有明显变化。结果表明，该果汁在5°C下储存3个月仍具有良好的可接受性。
如今，消费者对营养健康食品感兴趣，因为如各种专利所述，功能性食品可减少健康问题。因此，橙 - 薄荷叶混合汁对消费者来说将是一个不错的选择。
