Abstract
Novel triglyceride oils are provided for human consumption. Traditionally, agricultural materials such as canola, soybean, and olives have been the sources of edible oils, and such materials are limited by the geography in which these crops can be cultivated. Oils of the invention can be manufactured from edible and inedible heterotrophic fermentation feedstocks, including corn starch, sugar cane, glycerol, and depolymerized cellulose that are purpose-grown or byproducts of existing agricultural processes from an extremely broad diversity of geographic regions. The food oils disclosed herein are low in saturates, high in monounsaturates, and can be manufactured in reduced pigment form through the use of pigment-reduced microalgae strains. The food oils disclosed herein can be manufactured through the use of a variety of different types of oil-producing microalgae.
