摘要

为了确保椰子油的质量、口感、香气和营养特性保持一致，椰子仁或椰干的适当干燥对于椰子油的生产至关重要。本研究评估了不同干燥技术--热风干燥（HAD）、红外干燥（ID）和红外辅助热风干燥（IAHAD）--对从椰干中提取的椰子油质量特性的影响。椰核在不同温度（50 °C、60 °C和70 °C）下采用辐射和对流热风干燥法进行干燥。采用不同干燥技术从椰干中提取的新鲜油脂样品过氧化值为零，表明油脂质量很高。在这些方法中，60 °C的IAHAD法生产出的椰干品质最高，油的质量上乘，并能很好地保存必需的营养成分。使用 60 °C IAHAD 生产的椰子油的物理和生化特性包括比重、折射率、水分含量、抗氧化能力和总酚含量，所有这些都表明椰子油的质量得到了提高。

Comparative study on infrared radiation and hot air convective drying of coconut: Effect on oil quality features

Appropriately dried coconut kernel, or copra, is imperative for oil production to ensure consistent quality, taste, aroma, and nutritional properties of the resultant coconut oil. This research assesses the effects of different drying techniques—hot air drying (HAD), infrared drying (ID), and infrared-assisted hot air drying (IAHAD)—on the quality profile of coconut oil extracted from copra. Coconut kernels were subjected to radiation and convective hot-air drying methods at varying temperatures (50 °C, 60 °C, and 70 °C). The fresh oil sample extracted from copra using different drying techniques exhibited zero peroxide value, indicating high quality. Among the methods, IAHAD at 60 °C was remarkable for producing the highest-grade copra, resulting in superior quality oil with exceptional preservation of essential nutrients. The physical and biochemical properties of the coconut oil produced using IAHAD at 60 °C included specific gravity, refractive index, moisture content, antioxidant capacity, and total phenolic content, all indicating enhanced oil quality.

期刊介绍： Thermal Science and Engineering Progress (TSEP) publishes original, high-quality research articles that span activities ranging from fundamental scientific research and discussion of the more controversial thermodynamic theories, to developments in thermal engineering that are in many instances examples of the way scientists and engineers are addressing the challenges facing a growing population – smart cities and global warming – maximising thermodynamic efficiencies and minimising all heat losses. It is intended that these will be of current relevance and interest to industry, academia and other practitioners. It is evident that many specialised journals in thermal and, to some extent, in fluid disciplines tend to focus on topics that can be classified as fundamental in nature, or are ‘applied’ and near-market. Thermal Science and Engineering Progress will bridge the gap between these two areas, allowing authors to make an easy choice, should they or a journal editor feel that their papers are ‘out of scope’ when considering other journals. The range of topics covered by Thermal Science and Engineering Progress addresses the rapid rate of development being made in thermal transfer processes as they affect traditional fields, and important growth in the topical research areas of aerospace, thermal biological and medical systems, electronics and nano-technologies, renewable energy systems, food production (including agriculture), and the need to minimise man-made thermal impacts on climate change. Review articles on appropriate topics for TSEP are encouraged, although until TSEP is fully established, these will be limited in number. Before submitting such articles, please contact one of the Editors, or a member of the Editorial Advisory Board with an outline of your proposal and your expertise in the area of your review.
