“…In stability studies, 75 to 87% of retinyl palmitate content in UR was retained, depending on the cooking technique [40]. These findings were consistent with other studies demonstrating a high retention rate of retinyl palmitate in rice following boiling or heating at a low temperature [41,42,43]. After a 6 month storage period, retinyl palmitate in UR was shown to be more affected by temperature than by humidity, with an 85% retention of retinyl palmitate in UR stored at 23 °C compared to significant loses of retinyl palmitate content at temperatures over 35 °C [40].…”

Vitamin A deficiency continues to be an international public health problem with several important health consequences including blindness and overall increased rates of morbidity and mortality. To address this widespread issue, a series of strategies have been put into place from dietary diversification to supplementation and fortification programs. Retinyl palmitate has been used successfully for decades as a supplement as well as a way to fortify numerous foods, including vegetable oil, rice, monosodium glutamate, cereal flours and sugar. Recently, there has been rising interest in using a natural source of carotenoids, β-carotene from red palm oil (RPO), for fortification. Although RPO interventions have also been shown to effectively prevent Vitamin A deficiency, there are numerous challenges in using beta-carotene from RPO as a fortification technique. β-Carotene can induce significant changes in appearance and taste of the fortified product. Moreover, costs of fortifying with beta-carotene are higher than with retinyl palmitate. Therefore, RPO should only be used as a source of Vitamin A if it is produced and used in its crude form and regularly consumed without frying. Furthermore, refined RPO should be fortified with retinyl palmitate, not β-carotene, to ensure that there is adequate Vitamin A content.

“…This is consistent with previous studies which have shown that protection systems consisting of both antioxidant and chelating agents performed much better than systems which use antioxidant alone for protecting PUFA in avocado [24] and fish oil [25], and also vitamin A palmitate in ultra rice [26] from oxidation during storage. The mechanisms involved by which all three components achieve optimal stability of LCPUFA can be explained by the respective actions of these three components.…”

This study aimed to develop a capillary dried blood spot (DBS) system capable of protecting n-3 LCPUFA from oxidation for up to 2 months at room temperature (20-25°C). We demonstrated that a DBS system comprising both an antioxidant and chelating agent on silica-gel coated paper prevented any significant change in the n-3 LCPUFA profile after 2 months. Our DBS assay was then tested in fifty subjects, and this demonstrated the presence of strong and significant correlations between the results obtained from the DBS system and those obtained from conventional measures for all fatty acids, in particular the n-3 LCPUFA EPA and DHA (r>0.96, P<0.0001). This study therefore validates our DBS system as a reliable method for the assessment of n-3 LCPUFA status in humans.

“…have explicitly noted the superior performance of the ‘dry RP 250 S/N’ preparation. A related consideration may be the inclusion of an antioxidant system in the formulation – others have found this to be an effective means of increasing RP retention (Murphy, ; Li et al ., ). Secondly, a significant element of RP destabilisation in batches X1–X11 appears to be the low pH, as ‘vitamin A is very unstable below a pH of 5.0’ (Wirakarakusumah & Hariyadi, ).…”

The addition of NaFeEDTA at only 5% of total iron to ferric pyrophosphate-fortified Ultra Rice Ò increased the in vitro soluble iron ten-fold. Ultra Rice Ò formulated with NaFeEDTA at 2-7% of total iron, or with Na 2 EDTAÁ2H 2 O at 0.59 the total iron equivalents, increased the soluble iron seven-to thirty-fold. The colour of the batches was acceptable through 20 weeks at 21°C, but colour stability needs to be evaluated under authentic storage conditions. Although only 34-46% of the initial vitamin A remained after extrusion, 18-week storage at 30°C/70% relative humidity, and simulated cooking, there were indications that losses could be decreased by raising the pH (to~5) and/or using a better protected vitamin A ingredient. The enhancement of soluble iron afforded by low-level NaFeEDTA or Na 2 ED-TAÁ2H 2 O supplementation suggests that this fortification strategy may merit further study as a means of increasing absorbable iron in Ultra Rice Ò .
