**5. Nutritional properties**

*A. marmelos* nutrients are extremely beneficial for being a healthy human, and this evidence is already proved by various research studies. Recent research studies not only focused on the nutritional benefits of *A. marmelos* but also focused on its low-cost production and marketing to build a healthy environment. Main composition of *A. marmelos* nutrients is water (60–65%), carbohydrate (9–21%), sugars (11–17%), fibers (5%), and other compositions are vitamins, minerals, glucose, various fatty acids, and amino acids [3, 36, 37]. Bael can prevents rancidity and color loss because it contains a valuable amount of vitamin A (55 mg), vitamin B and vitamin C (8 mg), which can act as an antioxidant [3, 38]. *A. marmelos* fruit pulp contains 1.7% mineral contents with copper (0.21 mg), potassium (610 mg), calcium (80 mg), phosphorous (52 mg), and iron (0.60 mg/100 g) [39]. The calorific value of *A. marmelos* (88 cal/100 g) is higher than that of apple (64 cal/100 g), guava (59 cal/100 g), and mango (36 cal/100 g) [40]. Like other fruits, *A. marmelos* is also providing different nutritional values in different stages of maturity. For estimating crude protein in dried fruits by Micro Kjeldahl's distillation, to estimate crude fat Soxhelt method is used, ash content is estimated by incineration method

[21, 41]. Xylose, threose, glucose, galactose, fructose, arabinose, sucrose, galacturonic acid are present in *A. marmelos* as a polysaccharides and as a fat present like ricinoleic, linolenic, oleic, linoleic, palmitic, and myristic [42]. The major and important parts of nutrients are found in seeds and leaf.

In *A. marmelos* seeds, there is present 34.4% oil, stearic acid 8.8%, linolenic acid 8.1%, palmitic acid 16.6%, and oleic acid 30.5% [43]. This seed oil is used in aromatherapy, cosmetics, and in compressor [44]. *A. marmelos* oil can be used in medical purposes such as an anti-inflammatory, antiseptic, antimicrobial, antioxidant, astringent, disinfectant, carminative, and cytophylactic.
