Palm oil: potencial source of carotenes (mainly b- carotene)

INTRODUCTION

Utilization of palm oil carotene as food ingredient and food supplement

500 ppm

Red palm oil (RPO) Crude palm oil (CPO)

INTRODUCTION

RPO
Microen-

capsulation materials Materials

Homo-

genization RPO emulsion

Drying

MRPO Boundary conditions:

High viscosity of RPO
Suceptibility of b-caroten to high T

Suitable dryer

SLIDE 5

OBJECTIVES

1

to determine the most suitable

drying equipment for producing MRPO

2

to study the drying parameters of

the chosen drying equipment

SLIDE 6

METHODS

 RPO was produced in pilot plant scale of oil line

production at SEAFAST Center.

Material formulation Emulsification Drying of the emulsion Mikroencapsulated RPO

METHODS

SLIDE 8

METHODS

The drying experiments were conducted by

using tray dryer, drum dryer, and spray dryer

The drying time and drying process

performance were evaluated, and quality attributes of MRPO were measured.

RESULTS

The position of the tray and the thickness of

the RPO emulsion layer affected the drying time, moisture content, and drying rate

The thickness of emulsion layer will

determined drying time and drying rate to achieve the same moisture content

The recomended emulsion layer thickness

with good drying process parameters for tray dryer was 1.5 mm

SLIDE 12

CONCLUSIONS

Tray dryer can be used for producing high

quality of MRPO, regarding of b-carotene contents and recovery during drying process.

The process efficiency of tray dryer must be

improved by using continuous drying system
