White peach palm (pupunha) a new Bactris gasipaes Kunt variety from the Amazon: nutritional composition, bioactive lipid profile, thermogravimetric and morphological characteristics

This is the first investigation concerning the white peach palm (Bactris gasipaes Kunt) variety. The aim was to determine the nutritional composition, chromatographic profile, triglyceride composition, thermogravimetric-differential behavior, spectroscopic profile and morphological patterns. The analysis results showed that white peach palm is a promising source of nutritional compounds, such as lipids (7.80%), fiber (10.37%), proteins (5.35%), minerals such as copper, manganese and zinc, supplying from 30 to 80% of the daily recommended doses of those minerals The plant is low in sodium (1%) and has adequate selenium (above 10%). Its oil showed high quality and functionality (ω-6 and ω-3) and predominance of long-chain triacylglycerol, with high thermogravimetric stability (350 ºC), and no oxidative changes in its spectroscopic profile. The Morphological analysis revealed the presence of fibers and starches in the granules. The potential of this new variety expands the application possibilities of this matrix in different industrial segments.
