**4. Conclusions**

The characterization of wood apple fruit pulp showed a higher percentage of carbohydrate (24.74 ± 0.19%), protein (9.30 ± 0.16%), ash (2.73 ± 0.12%), and fiber (3.32 ± 0.02%), which is comparable to other citrus fruits such as bael (*Aegle mermelos*) and kumquat (*Fortunella marginata*). Wood apple fruits are also rich in organic acids, such as D-tartaric, ascorbic, and citric acid, which are accountable for the taste and quality of the fruits. The total free sugar content in defatted wood apple fruit pulp was 31.59 ± 0.17% DW. Fructose (16.40 ± 0.23%) and glucose (14.23 ± 0.10%) were the major sugars of the fruit pulp. Fatty acid profiling revealed that wood apple possesses a higher percentage of unsaturated fatty acids including oleic, α-linolenic, linoleic, and vaccenic acids. The results of the present study showed that the wood apple fruits are rich in nutritional components.
