Seasonal variation in the nutrient profile of Arthrospira fusiformis biomass harvested from an Ethiopian soda lake, Lake Chitu (2017)
Journal Article
Assaye, H., Belay, A., Desse, G., & Gray, D. (in press). Seasonal variation in the nutrient profile of Arthrospira fusiformis biomass harvested from an Ethiopian soda lake, Lake Chitu. Journal of Applied Phycology, doi:10.1007/s10811-017-1359-0. ISSN 0921-8971

The extent of seasonal variation in the nutrient profile of Arthrospira biomass harvested from Lake Chitu was investigated to evaluate the variability of the quality of the product over a period of a year. Protein content varied from 47.9 to 55.7% fo... Read More

Enhancing the recovery of oilseed rape seed oil bodies (oleosomes) using bicarbonate-based soaking and grinding media (2017)
Journal Article
De Chirico, S., Di Bari, V., Foster, T., & Gray, D. A. (2018). Enhancing the recovery of oilseed rape seed oil bodies (oleosomes) using bicarbonate-based soaking and grinding media. Food Chemistry, 241, doi:10.1016/j.foodchem.2017.09.008. ISSN 0308-8146

An aqueous process for the recovery of oil bodies from rapeseed using sodium bicarbonate-based soaking and grinding media (pH 9.5) was investigated. The effect of the ratio between seed and mass of media during grinding and molarity of the medium use... Read More

Influence of pecan nut pretreatment on the physical quality of oil bodies (2017)
Journal Article
Zhang, P., Di Bari, V., Briars, R., Taher, Z. M., Yuan, J., Liu, G., & Gray, D. A. (2017). Influence of pecan nut pretreatment on the physical quality of oil bodies. Journal of Food Quality, 2017(38641), doi:10.1155/2017/3864126. ISSN 0146-9428

A supply of pure, intact oil bodies is essential for carrying out morphological and biochemical studies of these plant organelles, and exploring their application. Preparation requires a carefully controlled breakage of plant cells, followed by separ... Read More

The role of plant cell wall encapsulation and porosity in regulating lipolysis during the digestion of almond seeds (2015)
Journal Article
Grundy, M., Carrière, F., Mackie, A. R., Gray, D., Butterworth, P. J., & Ellis, P. R. (2016). The role of plant cell wall encapsulation and porosity in regulating lipolysis during the digestion of almond seeds. Food and Function, 7(1), 69-78. doi:10.1039/c5fo00758e

Previous studies have provided evidence that the physical encapsulation of intracellular nutrients by cell walls of plant foods (i.e. dietary fibre) plays a predominant role in influencing macronutrient bioaccessibility (release) from plant foods dur... Read More

Composition and properties of the surface of oil bodies recovered from Echium Plantagineum (2013)
Journal Article
Payne, G., Lad, M., Foster, T., Khosla, A., & Gray, D. (2014). Composition and properties of the surface of oil bodies recovered from Echium Plantagineum. Colloids and Surfaces B: Biointerfaces, 116, 88-92. doi:10.1016/j.colsurfb.2013.11.043

Neutral-lipids within oilseeds are most commonly stored in oil bodies, small spherical organelles with oleosin proteins inserted through a phospholipid monolayer. Oil bodies extracted from Echium plantagineum are highly enriched in polyunsaturated fa... Read More

Aroma encapsulation and aroma delivery by oil body suspensions derived from sunflower seeds (Helianthus annus) (2011)
Journal Article
Fisk, I. D., Linforth, R. S., Taylor, A. J., & Gray, D. A. (2011). Aroma encapsulation and aroma delivery by oil body suspensions derived from sunflower seeds (Helianthus annus). European Food Research and Technology, 232(5), doi:10.1007/s00217-011-1459-z. ISSN 1438-2377

Oil bodies are small discrete cell organelles that can be found within oilseeds. Oil bodies have been investigated previously as a potential technology platform for use within the food industry, offering stable, antioxidant-enriched lipid-delivery... Read More

Tocopherol: an intrinsic component of sunflower seed oil bodies (2006)
Journal Article
Fisk, I. D., White, D. A., Carvalho, A., & Gray, D. A. (2006). Tocopherol: an intrinsic component of sunflower seed oil bodies. Journal of the American Oil Chemists' Society, 83(4), (341-344). doi:10.1007/s11746-006-1210-2. ISSN 0003-021X

Oil bodies were removed from mature sunflower through wet grinding followed by filtration then centrifugation and recovered as the buoyant fraction. Washing this fraction with buffer (water‐washed oil bodies, WWOB) or 9 M urea (urea‐washed oil bodies... Read More

Soybean (Glycine max) oil bodies and their associated phytochemicals
Journal Article
Fisk, I. D., & Gray, D. A. Soybean (Glycine max) oil bodies and their associated phytochemicals. Journal of Food Science, 76(9), doi:10.1111/j.1750-3841.2011.02428.x. ISSN 0022-1147

Abstract:  Soybean oil bodies were isolated from 3 cultivars (Ustie, K98, and Elena) and the occurrence of 2 classes of phytochemicals (tocopherol isoforms and isoflavones) and strength of their association with isolated oil bodies was evaluated. Toc... Read More
