Lipid Characterization of Chinese Wild Hazelnuts (<i>Corylus mandshurica</i> Maxim.)

Abstract

Introduction Hazelnut is one of the four major arboroid nuts in the world. There are about 20 species of hazelnuts, several species of hazelnuts such as C. America, C. avellana and C. colurna were widely cultivated in Asia, Europe and North America. Turkey is the world s leading producer of hazelnuts with a production of 400 000 tones, followed by European Union 145 000 tones , USA 37 200 tones and Azerbaijan 35 000 tones 1. In China, Hazelnut large area of cultivation is less, but there are wild varieties in the northeast and north of the mountains, Varieties are mainly Corylus heterophylla Fisch. and Corylus mandshurica Maxim. The main distribution of Corylus mandshurica Maxim is Hilly mountain in Heilongjiang, Liaoning and Jilin provinces of China. The average single weight and diameter of Corylus mandshurica Maxim is about 0.9 g and 1.37 cm, respectively, which is smaller than other species of hazelnuts. Currently, Hazelnuts are mainly used in the manufacture of food products including candy, chocolate, biscuits and pastries 2. In addition, other widely consumed product from hazelnuts is hazelnut oil 3. Hazelnut oil could be used

Crosstalk during the Carbon–Nitrogen Cycle That Interlinks the Biosynthesis, Mobilization and Accumulation of Seed Storage Reserves

“…Lipids are generally stored as triacylglycerols and represent an essential carbon storage form in many angiosperm seeds. Up to 80% of the total dry matter in some storage organs, such as nuts, cashews and hazelnuts, is composed of lipids [ 50 , 51 ]. They are water insoluble and deposited in discrete oil bodies, predominantly within seed storage tissue and in certain fruits, such as avocados and olives [ 52 ].…”

Oleochemical Properties for Different Fractions of Foxtail Millet Bran

“…The main TGA profiles were determined using an Agilent 1200 HPLC-MS Agilent, USA based on reference 18 . The oil was dissolved in hexane at about 48 mg/mL, and this solution was then diluted with acetonitrile/ isopropanol containing 0.5 ammonia 7/3, v/v to 4.8 mg/mL.…”

“…γ-oryzanol Vitamin E is comprised of tocopherols Ts along with tocotrienols T3s . The α-, β-, γ-, and δforms of Ts and T3s were analyzed using HPLC system according to the procedure of AOCS Ce 8-89 16 and reference 18 . Oil samples 0.5 g were dissolved in hexane at 50 mg/mL and filtered through a 0.22 μm pore size nylon syringe filter.…”
