Aims to find out how adding different amounts of hazelnut to corn flour affects women's blood glucose fluctuations. Women ( = 23) were given loaves of bread containing corn and hazelnut flour (50 g digestible CHO). They were given 50 g of glucose syrup to consume in the first week, normal corn-bread (CB) in the second week, 15 g of corn-bread with hazelnut flour (CB + 15HN) in the third week and 30 g of corn-bread with hazelnut flour (CB + 30HN) in the fourth week. Blood glucose was measured at 0, 15, 30, 30, 45, 60, 90, and 120 min. CB+HN15 AUC values were found to be significantly lower compared to the other breads ( < 0.05). In addition, The GI of CB+HN15 was significantly lower than the GI of the other two breads ( < 0.05). The positive effect on blood glucose fluctuations started to decrease when the addition of hazelnut flour was more than 15 g. Trial Registration: This study registered under ClinicalTrials.gov (Identifier no. NCT06382506).

Food reformulation is a strategy to make healthier foods by using food waste matrices that are still nutritionally valid. A shortbread cookie was reformulated replacing hazelnut skin (HS) of the Tonda Gentile Romana variety (5% and 10%) to refined flour and proportionally decreasing the butter amount. This resulted in significant, two- and five-fold, increases in the antioxidant capacity compared with the control, in the 5% and 10% fortified recipes, respectively.

This article presents a comprehensive overview of upcycling commercial nut byproducts (such as Brazil nut, cashew, hazelnut, macadamia, peanut (also known as a legume), pecan, pine nut, pistachio, and walnut) for food, nutraceutical, and pharmaceutical applications. Upcycling nut byproducts, namely husk/hull, hard shell, brown skin, defatted flour/meal/cake, pine cone, cashew nut shell liquid, cashew apple, walnut septum, and dreg/okara, has great potential, not only to reduce/minimise waste, but also to fit within the circular economy concept. Each byproduct has its own unique functional properties, which can bring significant value.

This study investigates the potential of utilizing hazelnut shells (HS) as an innovative filler in three-layer plywood technology, addressing the growing need for sustainable, high-performance materials. Traditional plywood production relies on adhesives enhanced with various fillers to improve physical, mechanical, and operational characteristics. This research explores using native, chemically modified, and activated carbon derived from hazelnut shells as fillers in urea-formaldehyde (UF) resin.

The Mediterranean region is distinguished by its gastronomic diversity and a wide variety of indigenous nut crops. In line with changing global food consumers' preferences, a noteworthy aspect is the increasing demand to the use of local varieties in recipe formulation. The aim of the present study was to incorporate the Terra Fria chestnut (Portugal) and Negreta hazelnut from Reus (Spain) in traditional Mediterranean recipes.
