The agricultural landscape is characterized by almond trees, cereals, fig trees, carob trees and vineyard. Guar gum has proven as useful substitute for locust bean gum (made from carob seeds). Because of its strong taste, carob syrup is sometimes flavored with orange or chocolate. Stabilizers such as carob bean gum and carrageenan are typically added in industrial production. Fruit, such as the sycamore fig, carob, mulberry, and possibly the apple were also eaten. Algarrobina is a syrup made from the Black Carob tree. The carob, olive, apple and pomegranate were introduced to Egyptians during the New Kingdom. Carob syrup is also used in Crete, and Cyprus exports it. Carob pulp is sold either as flour or "chunks". Date palms grow here as well as sycamore, carob and "Acacia". In the hills, olive and carob trees grow. Fructose and glucose levels do not differ between cultivated and wild carob. During this time the people on Malta mainly cultivated olives and carob and produced textiles. On the Iberian Peninsula, carob pods were historically fed to donkeys. The seeds of the carob tree contain leucodelphinidin, a colourless flavanol precursor related to leucoanthocyanidins.
