Vitamin A Status of Women and Children in Yaoundé and Douala, Cameroon, is Unchanged One Year after Initiation of a National Vitamin A Oil Fortification Program.

Vitamin A (VA) fortification of cooking oil is considered a cost-effective strategy for increasing VA status, but few large-scale programs have been evaluated. We conducted representative surveys in Yaoundé and Douala, Cameroon, 2 years before and 1 year after the introduction of a mandatory national program to fortify cooking oil with VA. In each survey, 10 different households were selected within each of the same 30 clusters (n = ~300). Malaria infection and plasma indicators of inflammation and VA (retinol-binding protein, pRBP) status were assessed among women aged 15-49 years and children aged 12-59 months, and casual breast milk samples were collected for VA and fat measurements. Refined oil intake was measured by a food frequency questionnaire, and VA was measured in household oil samples post-fortification. Pre-fortification, low inflammation-adjusted pRBP was common among children (33% &lt;0.83 µmol/L), but not women (2% &lt;0.78 µmol/L). Refined cooking oil was consumed by &gt;80% of participants in the past week. Post-fortification, only 44% of oil samples were fortified, but fortified samples contained VA concentrations close to the target values. Controlling for age, inflammation, and other covariates, there was no difference in the mean pRBP, mean breast milk VA, prevalence of low pRBP, or prevalence of low milk VA between the pre- and post-fortification surveys. The frequency of refined oil intake was not associated with VA status indicators post-fortification. In sum, after a year of cooking oil fortification with VA, we did not detect evidence of increased plasma RBP or milk VA among urban women and preschool children, possibly because less than half of the refined oil was fortified. The enforcement of norms should be strengthened, and the program should be evaluated in other regions where the prevalence of VA deficiency was greater pre-fortification

Indonesia plans to implement mandatory vitamin A fortification of cooking oil. A pilot study of voluntary vitamin A fortification in unbranded cooking oil showed that vitamin A status improved significantly a year afterfortification for five age groups except for children 12-23 months of age. The objective of the study was to measure cooking oil consumption and dietary consumption of vitamin A in children, women of reproductive age(WRA), and lactating mothers. The study was a cross-sectional study in Tasikmalaya and Ciamis, Indonesia, covering 1.594 samples randomly selected of poor households. Cooking oil was collected at household byrecall of usual cooking oil purchase and individual sample by 2x24h recall of food consumption. The results showed that households prefer bought unbranded cooking oil sold in plastic pouch at foodstall (warung) nearbyhome (96.2%), purchased oil every 1-3 days (60.6%), each purchace contained &lt; 250 mL oil (73.9%). The average (mean+SE) cooking oil consumption at household was 27.5+1.0 mL/capita/day. Cooking oilconsumption at individual level on the average was 22.3+0.5 mL/capita/day lower compared to household consumption of oil, varied significantly of 2.4+0.4, 13.3+0.8, 23.0+1.0, 30.5+1.3, 33.5+1.2, 33.1+1.3 mL/day in 6-11, 12-23, 24-59 month old, 6-9 year old, WRA, and lactating mothers respectively. Cooking oil consumptionwas lower in children 6-11 and 12-23 months old which contributed to non-significant improvement of serum vitamin A level particularly in children 12-23 months old but not other groups since they consumed higher intake of cooking oil or still brestfed for children 6-11 month old

Electrochemical impedance spectroscopy for palm cooking oil discriminator using planar electromagnetic sensor array

Cooking oil is an important product in the Malaysia food industries. Most of the cooking oil products is based on palm oil. However, there are activities in selling cheaper cooking oil by labelling as high quality in cooking oil product. Traditional methods have been developed to measure the quality of the cooking oil product such as the chromatography technique but the cost for the system setup is expensive and requires a large amount of time to analyse the sample. Thus, a suitable and reliable system with less analysis time is needed for widespread industrial uses. This paper has presented a discriminative technique for palm cooking oil using Electrochemical Impedance Spectroscopy (EIS) with planar electromagnetic sensor array. The sensor consists of a meander sensor and an interdigital sensors which interact with the test samples. Three types of palm cooking oil such as double refined palm oil, refined and deodorized palm oil with peanut and sesame oil, and filtered palm oil were prepared. The results obtained showed that the presented technique was able to differentiate the samples between 20 kHz to 1 Mhz. The results obtained correlate with the theories on EIS technique and planar electromagnetic sensor which are presented in this paper

Market power and subsidies in the Indonesian palm oil industry

Cooking oil is known as an essential commodity in Indonesia. Having such an important role, the Indonesian government often interfered the cooking oil market to assure its price remain low. To do so, the government uses a subsidy policy as one of its instruments. A dynamic duopoly model is applied to evaluate the impact of subsidies given the structure of the industry. Estimation results suggest an evidence of both an increase in the consumer surplus but a decrease in aggregate welfare due to market power. A possible reason is proposed, but, in order to obtain a clear explanation, further research is required.market power, subsidy, Indonesian palm oil industry, Agricultural Finance, Crop Production/Industries, Demand and Price Analysis,
