Lontar palm (Borassus flabeliffer L.) fruit is one of the specific tropical fruits from East Nusa Tenggara province (NTT)-Indonesia that is rich in functional compounds such as beta-carotene as an antioxidant and food fiber.  However, the utilization of these fruits is still limited due to the streroidal saponins and pholifenol content that makes them taste bitter and less favored by consumers. Therefore, one alternative that can be done is by enriching them into ice cream products. The production of Ice cream cannot go through with high heating processing so that the antioxidants extracted from lontar palm mesocarp can be in a stable condition. The aim of this study is to investigate the effect of ice cream on the acceptability values of the hedonic test, determining of fiber and beta-carotene content and evaluating antioxidant activities fortification from the lontar's mesocarp. The amount of lontar mesocarp for fortification (F) were 30%, 40% and 50% of the wet weight with the combination of some variation of milk treatment such as full cream milk, sweetened condensed milk, and liquid soy milk. The acceptability of the product was tested using hedonic test against color, aroma, texture, and flavor parameter. Antioxidant activity was performed by determination of the DPPH value (1.1-diphenyl-2picryhydrazil radical-scavenging), dietary fiber using enzymatic-gravimetric methods and UV-Vis spectrophotometers to analyze the content of beta-carotene. The results showed that on the acceptability test, the most preferred samples valued by panelists were the fortification, F1 treatment  (30%) with the content of β-carotene of full cream milk was 2212.44 ± 11.82 μg /100 mg, dietary fiber was 8.95 ± 0.05%, and antioxidant activity was 45.54 ± 0.36%.

The potential of Moringa seeds (Moringa oleifera Lam.) as an antioxidant compound is very important to be applied to food products so that their functional properties directly benefit the health of the body. The purpose of this study was to produce Snack bars of Moringa seeds and dried tomatoes with the highest antioxidant compounds by conducting DPPH analysis to measure antioxidant activity, and calculating total phenolic and vitamin C content. According to the results of the study, the best treated snack bars were found in products with 100% Moringa seeds, i.e. 62.41% antioxidant activity, 2.5 g/100 g total phenolic, and 15.44 mg/100 g vitamin C content.

This study aims to determine the effect of soaking time in distilled and non-distilled liquid smoke of kusambi wood (Schleicera oleosa) on the quality of smoked skipjack fillets. This study used an experimental method designed with a completely randomized design (CRD) with two factor treatments. The first factor was soaking time with four levels, namely 10, 20, 30 and 40 min. The second treatment factor was the type of liquid smoke from kusambi wood (without and with distillation). The variables observed in this study focused on the quality of the smoked skipjack fillets after the 8-day storage period, including: water content (%), pH, total acid (%), fat content (%) protein (%) and phenol content (%). The results showed that the liquid smoke of kusambi wood with distillation had a pH of 3.18 which was more acidic and had higher phenol content (0.61%) and acid content (17.62%) than liquid smoke without distillation. Of the eight treatment combinations, the quality of smoked skipjack fillets after 8 days of storage, it is found that the treatment of soaking 30 min and 40 min in distilled liquid smoke is the best treatment and meets the quality requirements of SNI. This is based on the value of water content (48.46% and 49.67%), pH (4.04 and 3.96), total acid (8.84% and 9.07%), fat content (4.85% and 4.92%), protein content (18.04% and 17.83%) and phenol content in smoked skipjack fillets (0.65% and 0.61%). Keywords: liquid smoke, distillation, soaking time, quality of smoked skipjack fillet

The snack bar is an alternative to local food development with a combination of nuts and fruits with a dense texture unified by a binding agent. Moringa seeds are known to have high nutritional content and antioxidant activity. This study aimed to analyze the effect of the baking process on the content of antioxidant compounds and the sensory quality of the snack bar supplemented with Moringa seeds. The snack bar treatment used the percentage of Moringa seeds, temperature, and time in the baking process. Determination of the Phenolic content of the product using the Folin Ciocalteu method and antioxidant activity using the free radical scavenger DPPH and followed by a preference test (hedonic analysis). The experimental design used was a completely randomized design using ANOVA If the result obtained showed a significant difference at the 5% (p 0.05), it would then be continued using Duncan’s Analysis. The results showed that there were significant increases in the antioxidant activity, phenolic compounds, and hedonic analyses, the higher the percentage treatment of 100% Moringa seeds with a baking time of 40 minutes at a temperature of 130 °C.
