Future prospects for palm oil refining and modifications

Abstract

Palm oil is rich in minor components that impart unique nutritional properties and need to be preserved. In this context, refining technologies have been improved, with the dual temperature deodorizer, the double condensing unit and the ice condensing system. The DOBI is a good tool to assess quality of the crude palm oil and its ability to be properly refined. Specially refined oils open a market for new high quality products (golden palm oil, red palm oil, white soaps, etc.). Palm oil is a good candidate for the multi-step dry fractionation process, aiming to the production of commodity oils and specialty fats (cocoa butter replacers). New technological developments allow quality and yield improvements. Palm oil and fractions are also valuable feedstock for enzymatic interesterification in which applications are for commodity oil (low-trans margarines and shortenings) and for special products (cocoa butter equivalents, infant formulation, …).

Fat crystals: A tool to inhibit molecular transport in W/O/W double emulsions

“…The latter distorted round shape is ascribed to a fat crystal network, which dictates the shape of the W/O/W sPMF globules. sPMF consists mainly of nonsurface active triacylglycerols, which suggests predominantly bulk crystallization in the oil volume of the W/O/W globules. Cryo‐SEM images of the W/O/W sPMF (Figure a,b) validate the small fat globule size measured by light scattering and reveal the existence of a crystalline fat matrix.…”

Characteristics of Fresh Fruit Bunch Yield and the Physicochemical Qualities of Palm Oil during Storage in North Sumatra, Indonesia

“…From the data obtained, for all three varieties, the DOBI meets the requirement for excellent CPO at day 0, when it is harvested (control). However, after 7 days' storage (except in tenera), a DOBI below 2 testifies an oil with very poor quality, which is more difficult to refine [2]. It has been reported that after short-term storage of the palm fruits (30 min to 120 min), the chopped fruits produced a lower quality of palm oil [7].…”

“…The feed CPO has been shown to contain carotene at 632 ppm [11]. The carotene criterion determined by the specification and quality requirements for Lotox CPO was 600-700 ppm [2]. From the data obtained, the carotene content of dura ranged from 343-568 ppm, which was the value at day 0 (568.42 ppm) and is thus only suitable as a standard; after 7 to 28 days' storage, the carotene content decreased to < 500 ppm.…”

“…The milling equipment and the fresh fruit bunch (FFB) characteristics play an important role in producing good quality oil. The quality of the crude oil is important as it can greatly affect the efficiency of the refining process and the quality of the final product [2].…”

A Conceptual Framework for Analysing Supply Chain Performance of Oil Palm Refinery in Malaysia

“…In addition, there is one of processing industries in the downstream sector that connect with overall entities which it is the oil palm refinery. This industry produces many type derivative products of oil palm nevertheless they are processed through the different technology of processing industry [5].…”
