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.

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.
