    Abstract: "The natural mutant Cucurbita pepo Styriaca Group originates from Styria (Austria), known for its hull-less seeds and dark green pumpkin oil with a roasted nut flavour. Seeds and fruit tissues, such as mesocarp, endocarp, exocarp are notable for their nutritional and bioactive compounds, with potential applications in nutraceuticals and pharmaceuticals. Our research focused on these components throughout five distinct ripening stages over two consecutive years 2020–2021, examining the dynamics of proteins, amino acids, lipids, minerals, and heavy metals. Protein content varied significantly, the highest in the mesocarp and the lowest in the seeds. Glutamic acid and aspartic acid dominated the amino acid profile, while essential amino acids were most abundant in seeds, with leucine, lysine, phenylalanine, valine, and isoleucine reaching notable concentrations. Mineral composition shifted during maturation: potassium and phosphorus declined, calcium increased, and elements such as magnesium, copper, and zinc rose in later stages. Heavy metals remained within safe limits across all phases. Biochemical and mineral profiles vary significantly between tissue types and between maturation stages. Our findings highlight young, unripe fruits as a valuable source of proteins and lipids, with the largely neglected endocarp emerging as a promising raw material for diverse applications. Harnessing these underutilized components could open new avenues in the agri-food sector, animal nutrition, and the pharmaceutical and cosmetic industries, aligning with global trends and local opportunities."(...)
