Elephant apple, a fruit with numerous bioactive compounds, is rich in therapeutic qualities. However, its use in processed products is limited due to insufficient postharvest processing methods. To address this issue, an automatic core cutter (ACC) was developed to handle the hard nature of the fruit while cutting. The physical characteristics of the elephant apple were considered for designing and development of the cutter. The cutter is divided into four main sections, including a frame, collecting tray, movable coring unit, and cutting base with five fruit holders. The parts that directly contact the fruit are made of food-grade stainless steel. The efficiency of the cutter was analyzed based on cutting/coring capacity, machine efficiency, loss percentage, and other factors, and was compared to traditional cutting methods (TCM) and a foot-operated core cutter (FOCC). The ACC had an average cutting/coring capacity of 270–300 kg/h, which was significantly higher than TCM’s capacity of 12–15 kg/h and comparable to FOCC’s capacity of 115–130 kg/h. The ACC offered a higher sepal yield of 85.68 ± 1.80% compared to TCM’s yield of 65.76 ± 1.35%, which was equivalent to the yield obtained by FOCC. Therefore, the ACC outperforms TCM in terms of quality, quantity, and stress associated and is superior to FOCC in terms of higher efficiency of machine and labor.

Elephant apple (Dillenia indica L.) grows wild in Southeast Asia’s forests, including in China, India, Nepal, Bangladesh, and Sri Lanka. Elephant apples are considered essential fruit crops because of their high nutritional value, which includes high levels of vitamin C, carbohydrates, fats, fibre, protein, minerals, and fatty acids. It is important to understand the nutritional value and health benefits of elephant apples in order to increase fruit intake in people’s daily diets. The present review paper focuses on elephant apple’s phytochemistry, bioactive compounds, therapeutic value, and medicinal capabilities for designing and developing a wide range of food formulations. Proteins, minerals, fats, crude fibre, carbohydrates, vitamin C, tannins, malic acid, and glucose are abundant in the leaves, bark, and fruit of the elephant apple. In addition to nutritional components, many phytochemicals found in elephant apples have been identified as bioactive compounds with a broad range of biological activities, the most prominent of which are antioxidant, anticancer, antidiabetic, and anti-inflammatory properties. Overall, elephant apple is a rich, natural source of bioactive compounds with potential applications in the production of value-added foods and nutraceuticals for disease prevention and management.

A mixed mode indirect solar dryer (MISD) was designed with a PCM-assisted polycarbonate glazed sheet covered solar collector and a drying unit for drying myrobalan. The rate of heat loss coefficients was evaluated experimentally with a modified collector design. The novelty of this work is the application of a PCM-energy storage in a conventional solar dryer to reduce the drying time of myrobalan. The thermal storage in MISD increases the continuous thermal supply period by 19±4 % compared to without thermal storage during the off-sunshine hour. The drying time of myrobalan was reduced to 12 h in MISD compared to 41 h in the OSD method. This results in better dryer performance and reduced drying time. The total useful energy was 61.18 MJ, and 0.206 MJ was reduced energy loss. The dryer's average temperature and relative humidity were measured as 65.2 °C and 8.83 %, respectively. The results show that exergy ef- ficiency increases, and exergy loss reduced in the MISD. An intensive experimental study on the thermo-physical properties of TES materials can be an additional advantage. Antioxidant values and the total phenolic content were evaluated by different methods. The best color and lower hardness values were achieved for a sample dried in MISD, as compared to other TD and OSD methods.
