Provided herein are microalgae of a Thraustochytrid and a method for preparing bio-oil using the same, and more particularly, Aurantiochytrium sp. LA3 (KCTC12685BP) having bio-oil producibility, and a method of preparing bio-oil, particularly bio-oil having a content of omega-3 unsaturated fatty acids of 30% by weight or more based on total fatty acids, characterized by culturing the microalgae. The microalgae Aurantiochytrium sp. LA3 (KCTC12685BP) described herein has a rapid sugar consumption rate when being cultured using glucose as a carbon source, has a high oil content, allows cells to be cultured at a high concentration, and allows oil to be obtained in high productivity and a high yield, and thus, may produce bio-oil more economically and environmentally friendly.

The present invention provides a chromatographic separation process for recovering a polyunsaturated fatty acid (PUFA) product from a feed mixture which is a fish oil or which is derived from fish oil, which process comprises the steps of: (i) purifying the feed mixture in a chromatographic separation step, to obtain a first intermediate product; and (ii) purifying the first intermediate product obtained in (i) in a simulated or actual moving bed chromatographic separation step, to obtain a second intermediate product; and (iii) purifying the second intermediate product obtained in (ii) in a simulated or actual moving bed chromatographic separation step, to obtain the PUFA product; wherein an aqueous organic solvent is used as eluent in each separation step; saturated and/or monounsaturated fatty acids present in the feed mixture are removed in the first separation step; the PUFA product is separated from different components of the feed mixture in steps (ii) and (iii); and the PUFA product obtained in the third separation step contains EPA or an EPA derivative in an amount greater than 90 wt %.

The present invention relates to a process for in situ regeneration of spent filter aid including the steps of: a) circulating through a spent filter aid cake in a circulation loop a regenerating oil at a temperature of from 40 C. to 100 C., in a regenerating oil/spent filter aid (v/w) ratio of from 0.3/1 to 12/1; b) removing the regenerating oil from the treated spent filter aid cake; and c) recovering the regenerated filter aid.

The present invention pertains to an efficient and large-scale process to produce a medium-chain triglyceride composition with >95% content for C8 (caprylic acid), C10 (capric acid) and C12 (lauric acid), with the content of lauric acid at about 5% or more. The process involves fractionation of fatty acid methyl esters, which are mainly derived from coconut or palm kernel, their esterification to glycerol to synthesize medium-chain triglycerides, and refining them to significantly increase purity and make them fit for human consumption. Such composition can have important uses in food and its preparation, health supplements, cosmetics, and medicine, among others.

The present invention relates to a non-dairy creamer and the triglyceride composition including a first ingredient, a second ingredient and a third ingredient. The first ingredient and the second ingredient together are from about 65wt % to about 80wt % by the weight of the triglyceride composition, and the third ingredient is from about 20wt % to about 35wt % by weight of the triglyceride composition. The first ingredient, the second ingredient and the third ingredient each have a MCPD content of less than 2500 ppb and a GE content of less than 1000 ppb. The first ingredient and the second ingredient are different, and the first ingredient and second ingredient are each selected from the group consisting of palm oil, palm kernel oil, palm kernel olein, palm kernel stearin, palm stearin, palm super stearin, palm olein, palm super olein, palm mid-fraction and a combination thereof. The third ingredient includes a lauric triglyceride.

The use of ultrasound or acoustics applied at a level below that which causes cavitation to control the energy balance between particles and the liquid phase in a metastable liquid.

It is provided a process for producing a purified essential oil excellent in safety and quality with high productivity from an essential oil comprising a harmful contaminant such as an agricultural chemical by simply and smoothly removing the contaminant with high removal rate without causing poor balance of flavor which the essential oil originally has, decrease of flavor strength and the like. It relates to a process for producing a purified essential oil by treating an essential oil comprising a contaminant with an active carbon to remove the contaminant and the removal rate of the contaminant is further improved by using an active carbon activated with a chemical, particularly an active carbon activated with zinc chloride, in the treatment, or by conducting the treatment at a low temperature of room temperature or lower, particularly at 25 C. to 5 C.
