A plant (1) for de-aerating and heating a vegetable product (100) comprises an extraction section (80) in which a vegetable starting product (5) is treated, in order to obtain an extracted vegetable product (100), in particular a puree, or a vegetable juice. The extracted vegetable product (100) is fed to a cold de-aeration section (10) obtaining an extracted vegetable product and de-aerated cold (105). The plant (1) also comprises a heating section (20) in which the de-aerated vegetable product (105) is heated from the starting temperature T1 to a final temperature T2, with T2>；T1, obtaining a heated de-aerated product (110). The plant (1) also comprises a storage reservoir (30) of the de-aerated vegetable product. According to the invention, the storage reservoir (30) is located downstream of the heating section (20), proceeding along the conveying direction of the de-aerated vegetable product through the plant (1). Therefore, the de-aerated vegetable product present in the storage reservoir (30) is a vegetable de-aerated and heated product (110). The plant (1) also comprises a deviation means (50) located downstream of the storage reservoir (30) and arranged to feed selectively the heated de-aerated product (110) in an outlet duct (41), for transferring the product out from the plant (1), or in a recirculation duct (42), for recirculating the product at a recirculation point (60) of the plant (1).
