Oleosome Oil Storage in the Mesocarp of Two Avocado Varieties

Abstract

INTRODUCTION The main feature that distinguishes the avocado fruit Persea americana Mill. is the high content of oil in the mesocarp, which gives the fruit its creamy texture and contributes to its flavor. The oil is a source of saturated palmitic and stearic acid , monounsaturated oleic and palmitoleic acid , and polyunsaturated linoleic and linolenic acid fatty acids that impart health benefits through anticholesterolemic, antioxidant, and anti-inflammatory activities 1 3. Studies on avocado fruit oil have mostly focused on the commercial cultivars, such as Hass, Bacon, and Fuerte, whereas few studies have been carried out on the fruits of native Mexican P. americana var. drymifolia and American P. americana var. americana varieties, despite their excellent medicinal and nutritional properties 4 7. The avocado tree belongs to the family Lauraceae, a primitive group of Angiosperms that was domesticated during the pre-Hispanic period in Mesoamerica as three botanical varieties P. americana var. americana, P. americana var. guatemalensis, and P. americana var. drymifo

Degeneration of oil bodies by rough endoplasmic reticulum (rER)-associated protein during seed germination in Cannabis sativa L.

“…LDs are present in all plant cell types, ranging from a few LDs per cell in leaves to thousands of LDs per cell in seeds ( Kang et al 2022 ). LDs are often referred to in the literature by various terms, for example, lipid bodies, oil bodies, oleosomes or spherosomes depending on the characteristics of the species ( Hsieh and Huang 2004 ; Purkrtova et al 2008 ; Sánchez-Albarrán et al 2019 ; Zienkiewicz and Zienkiewicz 2020 ; Nazari et al 2022 ; Guzha et al 2023 ). These organelles are surrounded by a half membrane and characteristically integrated with specific structural proteins ( Tzen et al 1993 ; Thiam et al 2013 ; Huang 2018 ; Ischebeck et al 2020 ).…”

Cytotoxicity of a Lipid-Rich Extract from Native Mexican Avocado Seed (Persea americana var. drymifolia) on Canine Osteosarcoma D-17 Cells and Synergistic Activity with Cytostatic Drugs

“…The lipid proportions vary among the varieties of avocado, but we focused on the Mexican native variety ( P. americana var. drymifolia) which shows the higher oil content (20–30%) [ 25 ]. The pulp lipids of the native Mexican avocado fruit have attracted attention due to their properties; however, the nutraceutical properties of seed lipids have been poorly studied.…”

Extraction and Physicochemical Composition of Irvingiagabonensis Almond Oil: A Potential Healthy Source of Lauric-Myristic Oil

“…It has also been observed that the difference in size can be related to variety. In the case of avocado, for instance, oleosomes of 41.5 µm were obtained for the Hass variety and 11.9 µm for the americana variety [27]. In future studies, it would be interesting to study the size of the oleosomes of I. gabonensis and correlate them with the variety, butter yield, and even the triglyceride composition.…”
