Abstract

Virgin Coconut Oil (VCO) yang merupakan salah satu produk olahan kelapa yang memiliki banyak manfaat kesehatan sulit dikonsumsi secara langsung karena rasanya yang berminyak (oily). Oleh karena itu, untuk membuatnya enak dikonsumsi, VCO dibuat dalam bentuk minuman emulsi. Pada penelitian ini, minuman emulsi VCO ditambahkan dengan jahe merah dan sereh yang bertujuan untuk menyelidiki pengaruh penambahan jahe merah dan sereh pada karakteristik fisik, kimia, aktivitas antioksidan, dan tingkat kesukaan panelis terhadap minuman emulsi VCO. Konsentrasi jahe merah dan sereh divariasikan: 100% jahe merah, 100% sereh, 50% jahe merah : 50% sereh, 75% jahe merah : 25% sereh, dan 25% jahe merah : 75% sereh. Hasil menunjukkan bahwa konsentrasi jahe merah dan sereh mempengaruhi warna minuman emulsi VCO yang dihasilkan. Penggunaan gum arab (7%) menghasilkan minuman emulsi VCO yang stabil selama waktu pengamatan 7 hari. Total gula (% sukrosa) berkisar pada 26,00%-28,67%. Total fenol dan bilangan peroksida minuman emulsi berkisar dari 20,92 – 28,61 mg GAE/ g sampel dan 0,08-0,79 mg ekuivalen O2/kg. Pada konsentrasi 15 ppm, aktivitas antioksidan minuman emulsi berkisar antara 58,58% - 71,20%. Minuman emulsi dengan penambahan 100% jahe merah paling disukai dalam aroma, warna, dan penampakannya, sedangkan minuman emulsi dengan penambahan 75% jahe merah dan 25% sereh yang paling disukai rasanyaVirgin Coconut Oil (VCO) as one of the coconut products with many health benefits hard to be consumed directly because of its oily taste. Therefore, to make it more tastier to consume, VCO will be made in form of emulsion drink. In this research, VCO emulsion drink will be added with red ginger and lemongrass to investigate the addition effect of these spices on the physical, chemical characteristic, antioxidant activity, and  panelist preference rate of its emulsion drink. The concentrations of red ginger and lemongrass were varied : 100% red ginger, 100% lemongrass, 50% red ginger : 50% lemongrass, 75% red ginger : 25% lemongrass, and 25% red ginger : 75% lemongrass. The result shows that the concentration of red ginger and lemongrass affected the color of the emulsion drink. The addition of arabic gum (7%) produced a stable emulsion drink during the observation time of 7 days. The sucrose percentage of the emulsion drink is 26,00% to 28,67%. The average of total phenol and peroxide numbers in the emulsion drinks was 20,92 to 28,61 mg GAE /g sample and 0,08-0,79 mg equivalent O2 / kg. At a concentration of 15 ppm, the antioxidant activity of emulsion drinks ranged from 58,58% - 71,20%. VCO emulsion drinks with the addition of 100% red ginger were the most preferred in terms of aroma, color, and its appearance, while the addition of 75% red ginger and 25% lemongrass were the most preferred in taste

Abstract

The aims of this research were to study the effect of temperature and storage on the oxidative stability of crude and refined canarium nut oil extracted from the seeds of Canarium indicum and Canarium vulgare. The experiment was designed to include storage of two type of canarium nut oil at two different temperatures for up to 35 days. The oils (crude and refined) used had the similar condition. Parameter used for oxidative deterioration indicators were two peroxide value, TBARS (thiobarbituric acid reactive substances), and free fatty acid value. The result showed that refining oil can decrease component natural antioxidant of canarium oil cause more sensitive to the oxidation. Increased storage temperature can raise oxidation of crude and refined oils from both species Canarium. The peroxide values of crude and refined oils both Canarium indicum and Canarium vulgare stored at 30 °C were 2.17, 4.35, 3.36 and 3.77 meq O2/kg oil, respectively. When they were stored at 4?C the similar results were 6.21, 19.09, 8.12 and 17.23 meq O2/kg oil. Furthermore, TBARS value of crude and refined oils both for Canarium indicum and Canarium vulgare stored 30?C were 4.55, 7.78, 5.70 and 6.58 µmol MDA/kg oil. When they were stored at 40 °C the similar results were 9.99, 55.46, 12.46 and 43.62 µmol MDA/kg oil.Key words: Canarium nut oil, peroxide value, TBARS

Abstract

Locally grown crops with phytochemical antioxidant content i.e. goroho plantain and yellow pumpkin were used to develop composite flour. Mixture experiment with simplex lattice design was used for formulation to study the effect of blending goroho plantain flour (GF) with yellow pumpkin flour (PF) on phytochemical content and antioxidant capacity of developed composite flours. Responses measured including phytochemical content (total phenolic and carotenoid), antioxidant capacity (DPPH assay, FRAP assay, phosphomolybdenum assay, and reducing power assay), colour values of flours, proximate components, and sensory quality of biscuits made from composite flours. The results showed that increase in proportion of PF improved the phytochemical content, antioxidant capacity, and proximate components with the exception of carbohydrates. However, substitution of GF with PF reduced sensory ratings for all the sensory attributes of biscuits developed from composite flours. Among biscuits made from composite flours, sensory ratings for aroma, colour, texture, and taste were not statistically different (p>0.05). PF can be used as fortification material to improve the phytochemical antioxidant content in composite flours prepared from GF and PF, or flours from other locally grown plants.

Abstract

Background: Food safety is the aspect considered to prevent food poisoning worldwide. Food safety management is essential to prevent foodborne illness. Objective: This study aimed to determine factors associated with the food safety behavior of members in the Village Food Security Movement Program in Bolaang Mongondow Regency, Indonesia. Methods: Cross-sectional research was conducted on 100 participants through a purposive sampling technique in the last week of February 2022 with the COVID-19 protocol. Data were collected using validated questionnaires. Descriptive statistical tests, Chi-square test, and multi-logistic regression were employed for data analysis. Results: The majority of the respondents were female (65%) and 15-59 years old. The Chi-square analysis found education, knowledge, and attitude were significant variables. After adjusting to the multi-logistic regression, the poor attitude and low cost of family food consumption were associated with poor food safety behavior (p <0.05). Conclusion: The most significant factors related to poor food safety behavior are the low cost of family food consumption and low attitude. The program must be appropriately arranged to prevent poor food safety behavior in the households.

Abstract

ABSTRACTBulbs Daluga (Cyrtospermamerkussi (Hassk) (Schott) is a type of local tubers in North Sulawesi region especially in Sangihe. It has high carbohydrate value that is 83.85% and 2.75% crude fiber. Processing of Daluga tubers into flour, provide opportunities of development being more varied, which indirectly helped the achievement of food security programs. As a damaged easy commodity, daluga require special prevention to extend the quality of safe,one of the main carried out is processed into flour substitution in this regard in making brownies. Brownies is a product bakery are included in the category of cake with the basic ingredients of flour. This study aimed to evaluate the acceptability of panelists to bake brownies that use raw materials substitution daluga flour. The benefit of this research is to provide information what percentage of flour that can be substituted daluga in making brownies. This study use randomized design with three replications object research, which are flour substitution treatment daluga 100% 0% wheat flour, flour daluga 80% 20% wheat flour, flour daluga 60%, 40% wheat flour, flour daluga 40% wheat flour and 20% 60% 80% daluga flour wheat flour. These results indicate that the resulting colour of the flour substitution daluga brownies are light brown, resulting from the addition of cocoa flour or cocoa powder. Taste of flour brownies daluga preferred by the panelists is caused due to components such as milk, eggs, flour and cocoa. The resulting aroma has a distinctive aroma of brownies in general. The texture of the soft and dense brownies due to additional materials such as eggs. While the expanding power is due to the heating. The greater the amount of flour, the greater the power generated expands brownies. Sensory quality or power/ test Thank Panelists most preferred is the use of 80% flour and 20% flour daluga tubers.Keywords: Wheat Daluga, Bake Brownies
