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: Penerimaan Minyak Sawit Mentah (MSMn) Sebagai Minyak Makan dan Pengaruhnya terhadap Konsentrasi α-Tokoferol Eritrosit pada Responden Program Sawit
Abstrak: Palm oil is one of the natural sources of vitamin A and E. Palm oil contains carotenoid compounds, tocopherol and tocotrienol. Tocopherol has vitamin E and antioxidant activity that protects erythrocytes membrane from free radicals attack and prevents cell hemolysis. SawitA is an applied program to develop products based on crude palm oil (CPO) which is still containing functional compounds. This research is a part of SawitA program that focuses more to the analysis of product acceptance, consumer behaviour, food choice and bioavailability of α-tocopherol in erythrocyte of a sub population. Product acceptance analysis was conducted through home use test method using 78 respondents in Neglasari and Sukadamai Village, Dramaga, Bogor. During 2 months period, this program provided two products for respondents which are “SawitA CPO” that given at the first month and “SawitA RPOWF”at the second month. Both products were given in bottles containing 140 ml per family per month. The distribution was accompanied by socialization of the benefit and utilization of the products. The results of respondents’ characteristic analysis indicated the major respondents were female, mostly housewive, and high school graduates. Most of respondents age ranged from 22 to 45 years old. The average income per capita of the respondents is Rp. 177.147,44 per month. The results showed that product was accepted 83.3-100 % by respondents with “like” category toward taste, odor, color, and over all attributes after two weeks until two months consumption. The product most used for sauting. However, all respondents preferred “SawitA RPOWF” to “SawitA CPO” because it has better taste, more neutral flavor and brighter color. α- Tocopherol level in erythrocytes measured in three respondents increase from 129.39 – 684.90 μg/dl to 469.57 – 2764.33 μg/dl after intervention. The increasing level of α-tocopherol is estimated as the influence of vitamin E in CPO.
