Judul: Pengaruh Konsumsi Produk Minyak Sawit Mentah dan Minyak Sawit Merah Tanpa Fraksinasi Terhadap Karakteristik Penerimaan Produk dan Kandungan Retinol Air Susu Ibu (ASI) pada Responden Program SawitA.
Abstrak: Crude palm oil is rich in carotenoids, tocopherol, and tocotrienol components. During processing into commercial cooking oil, major functional components of palm oil have degraded drastically. The objective of this study is to support socialization and education of crude palm oil (CPO) as a source of provitamin A. This study is a part of SawitA Program which was focused on the effects of CPO and unfractionated red palm oil (URPO) toward consumer acceptance and retinol concentration in human milk (ASI) in Neglasari dan Sukadamai Village, Dramaga, Bogor. Home Use Test (HUT) was conducted to 61 respondents after consuming two products, SawitA Gurih (CPO) and SawitA Tumis (URPO) during 2 months. Approximately 52% of respondents prefer URPO to CPO. Acceptability level of Sawita product had increased for daily usage. Average consumption of Sawita was 1,4309 g/cap/day. Average vitamin A intake from SawitA source was 163 RE/cap/day equal to 33% RDA. The analysis of retinol concentration in 6 samples of human milk was conducted using HPLC method. There is a significant increment of retinol concentration in human milk after SawitA consumption compared to initial state (p<0,05).

Judul: Pengaruh Konsumsi Minyak Sawit Mentah (MSMn) terhadap Penerimaan Sensori dan Kadar Retinol Binding Protein (RBP) Darah Responden Program SawitA
Abstrak: SawitA program is implemented in order to eliminate vitamin A deficiency utilizing CPO which is rich in carotenoid and scientifically proven to give health benefit to human body. This study focuses on the effect of CPO toward respondent acceptance and its health benefit in Babakan, Dramaga, and Sukadamai Village Bogor District. Home use test (HUT) was conducted to 72 respondents on consuming 2 – 3 mL per day CPO for 2 months. Most of the respondents are housewifes, on range 20-44 years old with elementary education backgrounds. Most of the family has low income (<250.000 rupiah) and high uniformity in food access. Acceptability analysis showed the respondent can accept CPO based on its colour (93%), taste (96%), and aroma (85%). By the consumption of 280 mL CPO will significantly increase RBP for 8,55% and 560 mL for 33,70-43,44% (α<0,05). The difference in CPO consumption is based on the difference in food consumption patten in each village and total family member who consumes CPO. Although CPO consumption is highly correlated to RBP increase (r=0,867, n=35,α<0.05). Thus, by consuming CPO is proven that it can help to fulfill retinol demand of respondents.
