Foreword

At the request of the Virgin Coconut Oil Producers and Traders Association of the Philippines, Inc. (VCOP), the Philippine Coconut Authority (PCA), a recognized Standard Development Organization (SDO) by the Department of Trade and Industry – Bureau of Philippine Standards (DTI-BPS), facilitated the amendment of the PNS for Virgin Coconut Oil (VCO) PNS/BAFPS  22:2007 to standardize the quality and ensure safety of VCO products distributed locally and exported globally. The Technical Committee (TC2) was composed of representatives from academe, VCO industry, research and testing institutions, government agencies, and professional organizations.

This standard was prepared with inputs from Dayrit et al., (2022). We thank the Philippine Council for Industry, Energy, and Emerging Technology Research and Development of the Department of Science and Technology (PCIEERD-DOST) for funding the research project.

This standard supersedes PNS/BAFPS 22:2007 ICS67.200.10 Virgin Coconut Oil.

1. Scope
This standard applies to Virgin Coconut Oil (VCO) intended for human consumption including use as Food Supplement.
2. Normative Reference
PNS/BAFPS 22:2007 ICS67.200.10 Virgin Coconut Oil
3. Definition of Terms
For the purpose of this document, the following terms and definitions apply.
3.1
Centrifugation Method
a technique in VCO production to separate the oil from coconut milk using rotational force of a centrifuge

3.2
Coconut Meat/Kernel
Also called endosperm, is the firm white, edible flesh attached to the shell

3.3
Coconut Milk and Coconut Cream
Coconut cream is a thick white emulsion obtained by manually or mechanically pressing the fresh, grated mature coconut kernel. Coconut milk is a less viscous emulsion that is obtained by addition of water or coconut water to the coconut cream. The term coconut milk may be used to refer to both coconut milk and coconut cream which are intermediate products of the wet process.

3.4
Expeller-pressing Method
fresh-dry method of VCO production where the VCO is squeezed from dried, grated coconut kernel using an expeller

3.5
Food/Dietary Supplement refers to a processed food product intended to supplement the diet that bears or contains one or more of the following dietary ingredients: vitamin, mineral, amino acids, herb or dietary substance or botanical, animal, artificial or natural origin to increase the total daily intake in amounts conforming to the latest Philippine recommended energy and nutrient intake or internationally agreed minimum requirements.

3.6
Free Fatty Acids (FFA)
fatty acids present in the oil that are not chemically bound, the amount of which is used as indicator of hydrolytic deterioration of the oil

3.7
Glycerides
compounds formed by the combination of glycerol and fatty acids which occur naturally in oils and fats

3.8
Mature Coconut
Coconut which exhibits change in husk color from green or yellow or orange to brown or grayish-brown. This occurs from 10 to 12 months after pollination.

3.9
Natural Fermentation Method
method of VCO production wherein the freshly squeezed coconut milk is allowed to stand for several hours until the oil separates from the aqueous (o/w) emulsion by inherent microbial and enzyme action

3.10
Testa
a thin brown layer between the shell and white coconut meat

3.11
Virgin Coconut Oil (VCO)
clear colorless unadulterated oil obtained from the fresh kernel of the mature coconut by mechanical or physical extraction or natural fermentation methods, with or without application of heat, without undergoing chemical refining, bleaching or deodorizing. Below 25°C, VCO solidifies and becomes white in color.

4. Process
VCO can be described according to the principal process that is used in obtaining the oil from the fresh coconut kernel or coconut milk. Addition of chemicals is not permitted. The use of heat should not cause the oil to turn slightly yellow or have a burnt flavor. Processing temperature should not exceed 90°C.

5. Essential Identity and Quality Characteristics
VCO consists mainly of triglycerides with a composition that is predominantly saturated medium chain fatty acids and stable to oxidation even when exposed to high temperatures. The fatty acid composition of VCO is distinct from animal fats, which are composed mainly of long chain fatty acids. Refer to Table 2 for the VCO fatty acid composition.

10.11   Metal analysis

According to the official methods listed in the table below.

Table 7. References for metal analysis.

Metal AOAC Official Method ISO AOCS
Copper 990.05 8294:1994 or 21033:2016a Ca 18b-91 (03)
Iron 990.05 8294:1994 or 21033:2016a Ca 18b-91 (03)
Lead 972.23c or 994.02, or 2015.01b 12193:2004 or 21033:2016a Ca 18c-91
Arsenic 957.22-1960(2002), or 985.16 or 2015.01b    
a ISO 21033:2016 is a direct, simultaneous determination of most of the trace metals (mercury and arsenic are not included) in animal and vegetable fats and oils by inductively coupled plasma – optical emission spectrophotometry (ICP-OES). The samples are diluted in a solvent (usually xylene), and the solution is directly aspirated into the ICP-OES.
b AOAC 2015.01 is a general method for the determination of Pb, Cd, As and Hg in food using inductively coupled plasma – mass spectrometry. Since this is a new method, further validation will be needed for its applicability to oil samples.
c AOAC 972.23 is a method for the determination of lead in fish, will need further validation if it is to be used for oils

 

11. Methods of sampling

Sampling shall be based according to CAC/GL 50-2004 (Codex General Guidelines on Sampling), CAC/RM 42-1969 (Codex Sampling Plans for Prepackaged Foods) or ISO 5555:2001 (Animal and Vegetable Fats and Oils, Sampling).
