Abstract
The aim of this study is to provide a literature review on biofortified products and their role in the scientific sphere. Despite the large number of studies conducted on biofortified products in the last 20 years, many defining issues are still debated in the literature and several research questions should be clarified. It is therefore relevant to investigate more on this topic, which is considered increasingly important to human health, world hunger reduction strategy, and also for the international marketing strategy of production holdings. The papers were analyzed according to a chronological/conceptual approach, with greater emphasis on research that has added significant value to the literature. The research was carried out using a scientific database from which 1189 scientific papers were extracted. A careful analysis of the abstracts and the text led to the identification of the five dimensions of our greatest interest (Reducing world hunger; Human health; GMOs; Agronomy, herbaceous crops; Economy and the market). The suggestions for future research reported by various authors are organized and structured in order to create an incentive for new studies and insights into biofortification.

Summary
The main objective of agricultural innovations, whether technological, agronomic or genetic, has been to increase the final yields. Until the 1990s, limited attention was given to improving nutritional qualities. In recent years, increasing attention has been paid to “hidden hunger,” two research terms used to indicate people around the world who suffer from vitamin and micronutrient deficiencies. Malnutrition is still a global health problem with many related diseases [1]. This phenomenon has a significant socio-economic impact and has contributed, together with difficult social and environmental conditions to the current situation in lowand middle-income countries [2,3]
