The addition of red palm oil in palm sugar will affect the content and retention of carotene as well as physical and sensory properties of the product during storage which were also influenced by packaging types. This study aimed to evaluate the changes in physical, chemical and carotene retention during storage of palm sugar. Palm sugar enriched with red palm oil was made by addition of two types of red palm oil (CPO and RPO ) and the amount of the addition (30 ml , 60 ml and 90 ml ) / 10 L coconut sap, after that packed with a single packaging (polypropylene, PP) and doublepackaging (PP + brown paper ) and stored for 2 months. After stored for 2 months, the level of total carotenoids of coconut palm sugar enriched with RPO decreased between 4.99 to 49.79 % with carotene content between 703 µg/100g up to 13383 µg/100 g. The decreased level of total carotene in first month and second month storage of coconut palm sugars enriched with RPO was higher (17.48 % and 24.47 %) compared to coconut palm sugar enriched with CPO (7.47% and 12.95 %) (p<0.05). The use of double packaging (polypropylene plastic + brown paper) is able to inhibit the decrease in total carotenoid up to 4.00 % to 6.67 %, better than the single packaging. The longer the storage, moisture content of product increased. However, after stored up to 2 months, the water content in all treatments was in range of SNI-01-3743-1995 standard (< 10 %) which is between 8.55 % up to 9.94 %.Keywords: Red palm oil, carotene retention, coconut palm sugar, storage, packaging ABSTRAKPenambahan minyak sawit merah pada gula kelapa akan berpengaruh terhadap kandungan dan retensi karoten, serta sifat fisik dan sensori produk selama penyimpanan yang juga dipengaruhi oleh jenis pengemas. Penelitian bertujuan untuk mengevaluasi perubahan sifat fisik, kimia dan retensi karoten selama penyimpanan gula kelapa. Gula kelapa yang diperkaya minyak sawit merah dibuat dengan penambahan dua jenis minyak sawit merah (CPO dan RPO) dan jumlah penambahannya (30 ml, 60 ml dan 90 ml) / 10 L nira kelapa, serta dikemas dengan pengemas tunggal (plastik polypropilene/PP) dan pengemas ganda (plastik PP + kertas coklat). Makin lama penyimpanan terjadi penurunan kekerasan tekstur, retensi dan kadar total karoten, sebaliknya untuk parameter kadar air dan kadar gula reduksi terjadi peningkatan. Setelah disimpan selama 2 bulan, kadar total karoten gula kelapa yang diperkaya karoten dari CPO maupun RPO turun antara 4,89 % - 49,79 % dengan kadar karoten antara 703 µg/100 g – 1338,3 µg/100 g. Makin banyak jumlah penambahan CPO maupun RPO, persentase penurunan total karoten selama penyimpanan makin kecil. Penurunan kadar total karoten bulan ke-1 dan ke-2 pada gula kelapa yang diperkaya RPO lebih tinggi (17,48 % dan 24,48 %) dibandingkan gula CPO (7,47 % dan 12,95 %) (p<0.05). Penggunaan pengemas ganda plastik polypropylene dengan kertas coklat (payung) mampu menghambat penurunan total karoten hingga 4,00 % sampai 6,67 % lebih baik dibandingkan pengemas tunggal. Makin lama penyimpanan, kadar air produk makin meningkat. Namun demikianhingga penyimpanan selama 2 bulan, kadar air produk pada semua perlakuan masih dalam kisaran standar SNI-013743-1995 (< 10 %), yaitu antara 8,55 % - 9,94 %.Kata kunci: Minyak sawit merah, retensi karoten, gula kelapa, penyimpanan, pengemas

Beta-carotene-rich fat powder was prepared from the mixture of red palm oil/RPO (olein and stearin) and fully hydrogenated palm oil/FHPO by using spray chilling process. Effects of composition of fats used on fat powderflowability, were studied. Our research showed that spray chilling process may be used to produced β -carotene rich-fat powder. Our result also indicated that the use of higher composition of RPO to increase β-carotene content of fat powder tend to reduce the flowability of the resulting fat powder. The maximum ratio of RPO/FHPO used to produce free flowing fat powder was 50% (formula of F50) with β-carotene content of 167.71 ppm. Our research also showed that the melting point of molten mixture fat used was significantly correlated with flowability of the resulting fat powder. The higher melting point of molten fat, the lower the angle of repose or the better flowability of fat powder produced.Keywords: Fat powder, β-carotene, spray chilling, flowability ABSTRAKLemak bubuk kaya β-karoten telah dibuat dengan menggunakan campuran minyak sawit merah (MSM) fraksi olein dan stearin, serta minyak sawit terhidrogenasi penuh (FHPO) melalui proses pendinginan semprot.

This double-blinded, randomized, controlled study was designed to study the effect of dietary supplementation with red palm oil during pregnancy on maternal and neonatal vitamin A status. A total of 170 women were recruited at 16 to 24 weeks of gestation and randomly assigned to an experimental group that received red palm oil to supply approximately one recommended dietary amount (RDA) (2,400 μg) of β-carotene or to a control group that received an equivalent volume of groundnut oil. The women received the oils for a period of 8 weeks, starting at 26 to 28 weeks of gestation and extending to 34 to 36 weeks of gestation. The mean postintervention (34 to 36 weeks) levels of serum retinol were 1.20 ± 0.22 (SD) μmol/L (95% CI, 1.15–1.25) in women receiving red palm oil and 0.73 ± 0.15 μmol/L (95% CI, 0.69–0.77) in their infants; these levels were significantly higher than those in women receiving groundnut oil (1.07 ± 0.26 μmol/L; 95% CI, 1.01–1.13; p < .01) and their infants (0. 62 ± 0.17 μmol/L; 95% CI, 0.57–0.67; p < .001). A significantly lower proportion of women in the red palm oil group than in the control group had vitamin A deficiency (serum retinol levels < 0.7 μmol/L) after intervention (1.5% vs. 9.7%). The proportion of women having anemia was significantly lower (p < .01) in the red palm oil-supplemented group (80.6%) than in the control group (96.7%). The mean birthweight and gestational age of the infants did not differ significantly between the two groups. An increased risk of low birthweight (p = . 003) and preterm delivery (p = . 000) was observed with decreasing serum retinol levels in the third trimester of pregnancy. These results show that red palm oil supplementation significantly improved maternal and neonatal vitamin A status and reduced the prevalence of maternal anemia. Maternal vitamin A status in the later part of pregnancy is significantly associated with fetal growth and maturation. Hence red palm oil, a rich source of bioavailable vitamin A, could be used as a diet-based approach for improving vitamin A status in pregnancy.
