Strawberries have antioxidant, cardiovascular, and antiproliferative properties. The agroindustrial production of strawberry concentrate generates a food waste after extrudation that is usually landfilled. This strawberry extrudate is a rich source of valuable bioactive compounds such as phenols and sugars. In the present study, industrial thermal treatments currently in use for the valorization of other agricultural wastes were determined to be suitable for the treatment of strawberry extrudate. Thermal treatment conditions in the range of 90 °C to 200 °C were studied. Thermal treatment at 150 °C for 60 min without acid addition was the most efficient process based on the solubilization of sugars and phenols as well as the antioxidant capacity of the liquid phase produced. Instead of sending this residual fraction to landfill, such treatment would permit the use of strawberry extrudate as a source for the recovery of valuable bioactive compounds.

草莓具有抗氧化剂，心血管和抗增殖特性。草莓浓缩物的农用工业生产在挤压后产生食物垃圾，通常将其填埋。这种草莓挤出物是有价值的生物活性化合物（如酚和糖）的丰富来源。在本研究中，目前用于对其他农业废物进行增值的工业热处理已确定适合于草莓挤出物的处理。研究了90°C至200°C范围内的热处理条件。基于糖和酚的增溶作用以及所产生液相的抗氧化能力，在150°C下进行60分钟的热处理（不添加酸）是最有效的方法。而不是将这些剩余部分发送到垃圾填埋场，
