Comparison of multispectral modeling of physiochemical attributes of greengage: Brix and pH values
Greengage, which currently grows mainly in the coastal areas of Southeast China, is nutritional and categorized as one of the strong alkaline forming foods. It is useful in neutralizing the acidity of blood and keeping the body fluids alkalescent. Besides, it can be used to alleviate the acidification of body fluids and reduce the risk of diseases, such as cardiovascular and cerebrovascular diseases, osteoporosis, kidney stones, arthritis, gout, and cancer (Tian et al., 2018). Greengage fruit has a long history of being used in traditional Chinese foods as pulp served dried or salted, or as an ingredient in fruit wine, as well as for traditional Chinese medicine. But these simple-processed products have low added values. Currently, the surplus supply of greengage due to its increasing growing area in the past decades has already saturated the market of conventional greengage processing industry. Therefore, there is an urgency to upgrade the greengage processing industry with new products of more added values.
