Impact of Heat and Pressure Processing Treatments on the Digestibility of Peanut, Hazelnut, Pistachio and Cashew Allergens

Food processing can alter protein biochemical properties, impacting immunoreactivity and allergenicity. A key feature of food allergens is their resistance to enzymatic digestion, particularly by pepsin and trypsin. This study compares the digestomes of raw and heat- and/or pressure-treated peanuts, hazelnuts, pistachios and cashews using the INFOGEST harmonized digestion protocol and analyzing their IgE-binding capacity […]

New Meta-Analysis Strengthens Evidence That Nuts May Lower Cardiovascular Risk

The findings refute a study questioning the benefits of nut consumption A systematic review and meta-analysis funded by the International Nut and Dried Fruit Council (INC) has just been published in the prestigious scientific journal Nutrition, Metabolism and Cardiovascular Diseases.[1] The study showed that current evidence provides a good indication that consuming nuts may advantageously […]

The Influence of Various Modifications of Hazelnut Shell Flour as Potential Filler in Plywood Technology

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 […]

Sensory optimization of gluten-free hazelnut omelette and sugar-modified chestnut pudding: A free choice profiling approach for enhanced traditional recipe formulations

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) […]

Investigation of antioxidant edible coating and modified atmosphere packaging for enhancing storability of hazelnut kernels

This study investigated the effects of antioxidant edible coating and modified atmosphere packaging for improving storability of dried hazelnut kernels by delaying lipid oxidation and color degradation. Hazelnut kernels were coated with different coating matrix (methylcellulose and chitosan) that contain different antioxidant substances (DL-α-tocopherol acetate, cinnamon essential oil, rosemary essential oil and hazelnut oil) and […]

Exploring the bioactive potential of dried fruit by-products: a focus on hazelnut, peanut, and almond teguments and shells

Dried fruits are renowned for their nutritional value, particularly their seeds. However, their skins, shells, and hulls also hold significant nutritional and commercial potential, yet remain largely unexplored for their bioactive compounds. This study examines the teguments and shells of three types of dried fruits – hazelnut, peanut, and two almond varieties. Ethanol extracts from […]

INC Unveils Gen Z Preferences for Nuts and Dried Fruits and Snacking in Latin America

Peanuts, almonds and walnuts are consumed the most among Gen Z in Latin America 96% snack between meals, yogurt, dairy products, and fresh fruits being common choices Taste and health benefits are the primary drivers for consuming nuts and dried fruits INC’s NutTunes campaign set to encourage nut and dried fruit consumption through Spotify The […]

Powdery mildew caused by Erysiphe corylacearum: An emerging problem on hazelnut in Italy

Erysiphe corylacearum has recently been reported in northern Italy (Piedmont) and other European countries as the causal agent of a new emerging powdery mildew on hazelnut. This disease is much more dangerous than the common hazelnut powdery mildew caused by Phyllactinia guttata as it significantly reduces yield and quality of hazelnuts. This study aimed to […]

Effects of enzymatic hydrolysis combined with pressured heating on tree nut allergenicity

Hazelnut, pistachio and cashew are tree nuts with health benefits but also with allergenic properties being prevalent food allergens in Europe. The allergic characteristics of these tree nuts after processing combining heat, pressure and enzymatic digestion were analyzed through in vitro (Western blot and ELISA) and in vivo test (Prick-Prick). In the analyzed population, the […]
