Indonesia as a tropical country has various kinds of fruit varieties. One of the famous fruits in Indonesia is guava. Guava fruit is popular with the public because it has a sweet taste. Ripe guava flesh can be processed into processed products such as jelly, jam, guava flour, fruit salad, fruit soup, chips, fruit juice, and fresh drinks. The benefits of guava fruit are many, such as being able to overcome several types of diseases such as diabetes, hypertension, and cancer. In addition, guava is also useful as an anti-bacterial, anti-fungal, anti-inflammatory, and can maintain skin health. Guava contains various vitamins and antioxidants that are beneficial for the body.
