Land Use/Change and Local Population Movements in Stone Pine Forests: A Case Study of Western Türkiye
One of the important distribution areas of stone pine (Pinus pinea L.), a native tree species of the Mediterranean Basin in Türkiye, is the Kozak Basin. Pine nut production plays an important role in the livelihood of the rural people of the Kozak Basin. However, in recent years, as a result of mining activities, climate change, […]
Upcycling commercial nut byproducts for food, nutraceutical, and pharmaceutical applications: A comprehensive review
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, […]
Dendrochronological Analysis of Pinus pinea in Central Chile and South Spain for Sustainable Forest Management
Pinus pinea is an important Mediterranean species due to its adaptability and tolerance to aridity and its high-quality pine nuts. Different forest types located in Mediterranean native and non-native environments provide the opportunity to perform comparative studies on the species’ response to climate change. The aims of this study were to elucidate growth patterns of […]
Rigid Polyurethane Biofoams Filled with Pine Seed Shell and Yerba Mate Wastes
Pine seed shells and yerba mate are common wastes leftover from the food and beverage industry. This study presents the development of rigid polyurethane foams (RPUFs) filled with pine seed shells and yerba mate at 5, 10 and 15 wt%. The fillers were characterized for chemical properties using bench chemistry analyses, and the RPUFs were […]
Influence of biomass components, temperature and pressure on the pyrolysis behavior and biochar properties of pine nut shells.
The aim of this work was to compare the yields, proximate composition, structure and surface morphology of biochar derived from lignin, cellulose, hemicellulose and pine nut shell (PNS) at 400-700 ℃. PNS biochars obtained at different pyrolysis pressures in the range of 0.1-2.0 MPa were also studied. The results indicate that the interactions of lignin, […]
Investigation of effectiveness of pyrolysis products on removal of alizarin yellow GG from aqueous solution: A comparative study with commercial activated carbon.
The increasing use of dyestuff in industrial applications brings with it environmental problems. These dyes, which are an eco-toxic hazard, are common water pollutants, even at very low concentrations in water resources. Therefore, they must be removed in an economical way. In this study, low-cost biosorbents such as pine cone char, walnut shell char, and […]
Cetyl trimethyl ammonium bromide modified magnetic biochar from pine nut shells for efficient removal of acid chrome blue K.
Biochar was prepared by rapid pyrolysis using pine nut shell as raw materials. Then cetyl trimethyl ammonium bromide modified magnetic biochar material (CTAB-MC) was obtained after modifying biochar by FeCl3 and cetyl trimethyl ammonium bromide. The CTAB-MC was characterized by SEM, FTIR, XRD and Magnetic analyses. Adsorptive property of the CTAB-MC for acid chrome blue K […]
Plant extracts such as pine nut shell, peanut shell and jujube leaf improved the antioxidant ability and gas permeability of chitosan films.
In order to develop the antioxidant and gas permeability packaging film, the effects of three plant extracts (pine nut shell, peanut shell and jujube leaf) on the physical, antioxidative and structural properties of chitosan based biodegradable films were studied. The results showed that three plant extracts improved the antioxidant capacity of films. The DPPH radical […]
Moisture absorption and dynamic flavor changes in hydrolysed and freeze-dried pine nut (Pinus koraiensis) by-products during storage.
In the present study, two different fractions of pine nut (Pinus koraiensis) protein hydrolysate powder (PNPHP1-3kDa and PNPHP3-10kDa) were prepared and stored for fifteen days at 25°C and 50% relative humidity. Changes in moisture absorption, secondary structure and flavor compounds were measured at various time intervals over fifteen days. Results showed that the PNPHP3-10kDa had […]
