This study used a Completely Randomized Design (CRD) consisting of four treatments using the combination of Sargassum sp., E. cottonii and purple sweet potatoes respectively: 45: 5: 50% (S1), 40: 10: 50% (S2), 35 : 15 : 50 % (S3), 30 : 20 : 50% (S4) and repeat three times. The results of the research obtained showed a real effect on sensory values which included color, aroma, and texture. The test results of the chemical content of jam showed water content between 27.62 %, ash content 1.59 %, crude fiber 1.44 % and carbohydrates 88.96 %. The test results of antioxidant content with percentage inhibitor (IC50) that is 337.81 μg / mL respectively. The results of this study indicate that there is an influence on the content of water content, ash, crude fiber, total carbohydrates and antioxidant content present in the purple sweet potato jam in each treatment.Keywords: Eucheuma cottonii, Ipomoea batatas, chemical composition and antioxidants, Sargassum sp., Jam, Sensory test ABSTRAKPenelitian ini bertujuan untuk mengetahui pengaruh penambahan rumput laut jenis Eucheuma cottonii dan Sargassum sp. terhadap komposisi kimia, aktivitas antioksidan dan sifat sensori selai ubi jalar ungu.

This study assessed the nutrient composition, physicochemical, functional and sensory properties of flour blends prepared from cooking banana, pigeon pea and orange fleshed sweet potato flour blends for use as complementary food. Fourteen blends were generated using the simplex centroid mixture design. All data obtained were subjected to analysis of variance and the mean values were separated using Duncan’s Multiple Range Test. The protein, crude fibre, crude fat, ash and carbohydrate of the blends were significantly (p≤0.05) different with values ranging from 10.60-21.65%, 0.36-1.24%, 1.2-1.43%, 0.77 – 2.25% and 65.86 -75.36%, respectively. There was no significant (p≤0.05) difference in the moisture content, total carotenoid content and pH value of the blends. The L* value (40.77 to 45.25) showed no significant (p≤0.05) difference while the redness (a*) and yellowness (b*) value were significantly (p≤0.05) different with values ranging from 2.32 – 4.59 and 11.88 – 15.88 respectively. There was a significant (p≤0.05) difference in the bulk density (0.73 – 0.78 g/ml), water absorption capacity (122.05-178.10%), swelling power (6.21 – 8.48%) and solubility (3.77-7.30%) values. Gruels obtained from the flour blends had sensory scores of above 6.00 (on a 9-point Hedonic scale), signifying high acceptability for all the sensory attributes evaluated.

Orange Fleshed Sweet Potato

Breakfast strips were produced from different blends of orange-fleshed sweet potato (Ipomea batatas), plantain (Musa paradisiaca) and soybean (Glycine max) flours with substitution ratios of 100:0:0, 90:10:0, 90:0:10, 80:10:10, 70:15:15, 60:20:20 and 50:25:25 and labelled as samples A, B, C, D, E, F and G, respectively. The blends were evaluated for functional properties, total carotene, vitamins (B2 and B6) and sensory properties of the breakfast strips with a commercial breakfast food (Flakes) as control (sample H) . For the functional properties, the water absorption capacity decreased while the oil absorption increased with an increase in substitution levels of the soybean flour. The bulk density, solubility, swelling power and swelling volume were higher in sample A. The least gelation capacity maintained a constant rate of 4% across the blends. The moisture content of the strips ranged from 7.25-9.40%. The Ash contents were below 3% for all the blends. The protein contents increased with an increase in substitution with soybean flour while sample A - breakfast strips from 100% orange-fleshed sweet potato flour showed the highest value for fats (5.62%). The fibre content ranged from 0.69 to 5.14% and carbohydrate content reduced with an increased substitution with soybean flour (72.25-78.70%). The energy value ranged from 351.90-384.80 Kcal/100 g which was within the limit recommended for breakfast foods. Total carotene content increased with increased substitution with orange-fleshed sweet potato (15.18-33.56 mg/kg) which is significantly higher than the control at 0.75 mg/kg. The result of the sensory evaluation showed that the overall acceptability of the samples produced compared favourably with the control. Sample A and B showed a vitamin B2 of 4.70 and 4.00 mg/kg, respectively. However, the values decreased with increase in the addition of soybean while vitamin B6 increased with increase in soybean.

Microwave and steam blanching as pretreatments to hot air drying of orange-fleshed sweet potato (OFSP) were studied. The air-drying experiment was performed at constant temperature of 70°C and airflow of 1.0 m/s. The effective moisture diffusivity varied from 1.5 × 10 − 9 to 4.4 × 10 − 9 m2/s, and 1.1 × 10 − 10 to 7.9 × 10 − 10 m2/s, for the microwave and blanched assisted hot air drying, respectively. The activation energy obtained for the various microwave-assisted hot air drying was 29.1 W/mm for 4 min, 68.1 W/mm for 3 min, and 79.7 W/mm for 2 min. Ascorbic acid degradation and formation of brown pigments in the OFSP slices were lower in microwave than in steam blanch-assisted drying. Microwave-assisted drying of OFSP is best governed by Page model, M R = exp − k t n , while the blanch-assisted followed the logarithmic model, M R = a   exp − k t + c . To produce better quality OFSP flour, it is recommended to cut the tubers into 3 mm slices, microwave at a power of 630 W for 2 min or blanch for 1 min, 43 seconds prior to hot air drying.
