Abstract

Solar dryer with heat source energy replacement is one of environmental drying technology. This research aimed to determine water content, color analysis, vitamin C, total molds from chili powder, and dried chilli yield as quality for dried chili. Results showed moisture content of dried Red chilli and Local Chilli using solar dryer with heat source energy replacement are 7.3%bb and 6.24%bb, needs 10 hours and 8 hours respectively. Whereas moisture content of the same materials with conventional drying method are 11.89%bb and 8.63%bb, needs 71 hours and 41 hours respectively. Furthermore, color analysis of dried Red chili and Local Chilli and its powder using a dryer gives value of ​L a+ b+ higher than same materials and its powder with conventional drying methods. Vitamin C content on powder of those materials using a drier is higher at 54.33mg/100g and 27.73mg/100g respectively, while with the same material by conventional drying methods implies that 36.33 mg/100g and 8.60 mg/100g. Total mold analysis has highest value on Red chilli powder and Local Chilli powder with conventional drying methods are 6.46x102 colonies/g and 2.06x102 colonies/g. Whereas Local Chilli powder which dried using a dryer there is no mold, followed by dried Red chilli powder that is 1.1x102 colonies / g. The yield of dried Red chillies and Local Chilli ranged between 24.97%-32.17%, whereas the yield of dried chili with conventional methods is lower than using a dryer.   Key word: Quality, Chilli powder, Solar dryer

Abstract

The halua kenari is one of the signature product from North Sulawesi especially Minahasa and Siau. Fat and oil oxidation processes lead to taste and flavor dislike and degradation of nutrition and functional characteristics. Beside chemical composition, halua kenari degradation accelerated by improper handling and packing during transportation, distribution, and storage by consumer and seller. The aims of this research is to predict shelf life of halua kenari production of  Small And Medium Enterprises at District of Sitaro Archipelago with accelerated shelf life testing model (Arrhenius) and to get shelf life model of halua kenari production at small and medium enterprises at Sitaro Archipelago. This research was done in two stages which is determination of quality characteristic of halua kenari by chemical analysis and organoleptic test and shelf life of halua kenari by Accerelated Shelf Life Testing (ASLT) Model. Product was stored at extreme temperature to fasten deterioration. Data extrapolated to mathematical model Arrhenius. The processing characteristic, temperature, and  storage are very significant to quality degradation and shelf life of halua kenari. The shelf  life of halua kenari product with low fat and oil (A1) that stored at 30 o C is 106 days, as halua kenari with high fat and oil stored in the same temperature and days, found : A2 with 18 days shelf life, A3 with 23 days shelf life, and A4 with 17 days shelf life. Keywords : the halua kenari, the shelf life, Arrhenius model, water content, and FFA

Abstract

Canary is original plants Indonesia which growing many in Indonesia area part of east, like North Sulawesi, Maluku, Seram and Alor island. This study aims to determine the total conten of phenolic compounds and antioxidant activity of extracts of canary husk of some species of Canarium vulgare Sp. solvent is hexane, ethanol, ethyl acetate and acetone. Results showed that the canary husk extract of Canarium vulgare Sp. species has a total phenolic content and antioxidant activity are great. Highest total phenolic content of the extract produced by solvent acetone was 171.0 mg/kg, followed by extracts of ethyl acetate, ethanol, and hexane has a total phenolic content of consecutive 111,17 mgkg, 99,67 mg/kg, and 67,17 mg/kg and the highest antioxidant activity in the solvent ethyl acetate extract of 93.66% followed by 92.97% acetone extract, ethanol amounted to 89.92% and by 14.45% hexane. Result of this research indicate that canary husk acetone extract have fenolik content and highest antioxidant.

Abstract

An increasing production of avocado in Indonesia  has resulted in abundant seeds as wastes. Avocado’s seeds contain potential antioxidant compound, such as phenolic compound, which could be exploited for human consumption. Utilization of seeds as functional food could be more efficient by coating with a certain substance. Chitosan is a bio-compatible and non-toxic compound, and could be used as coating agent in the form of nanochitosan. The purpose of this study was to evaluate the content of  phenolic-compound in extract of avocado’s seed with and without coated by nanochitosan. In this study, the extract of avocado’s seed was coated with  Parrot fish scale (Scarus sp) derived nanochitosan, compared with nanochitosan from crab’s shell. Nanochitosan was prepared from chitosan by gelation ionic method. The results show that avocado’s seed extract has 44.89 mg/Kg of phenolic content,  much lower than the content in the extract coated with nanochitosan of fish and crab shell, which were 84.08  and 113,67 mg/Kg, respectively.   Therefore, coating with nanochitosan was proven increasing the phenolic compound in the extract of avocado’s seed.  Keywords: avocado, nanochitosan, phenol

Abstract

The purpose of this study was to determine the impact of red beet extract addition to melon marshmallow product towards the antioxidant activities, physical characteristic and sensory properties. The method that used in this study were folin ciocalteu methods for total phenol test, DPPH (1,1-diphenil, -2 picrylhydrazyl) method that used for the antioxidant activity test, penetrometer methods was used for hardness test, and hedonic scale for the sensory test. The result of this study showed that 15% addition of red beet extract was the best treatment towards antioxidant activities which has 83,42% inhibitions, IC50 value of 145,27 µg/mL. Furthermore, the treatment of 15% red beet extract addition also showed physical characteristic value (hardness) of 79,78 mm/g/s which is the closest value to commercial marshmallow. The treatment which has the best result of sensory properties was 10% red beet extract addition, that is 3,34 (neutral). Keywords: Antioxidant, Red Beet, Melon, Marshmallow

Abstract

"Mulu bebe" plantain (Musa acuminata) is a potential tropical fruit commodity in Indonesia, especially in the North Halmahera area where it can be used as part of food diversification. It is orange in color and no study has been done so far regarding physicochemical properties of starch and its resistant starch. This research was aimed to study the physical properties of “Mulu bebe” plantain flour modified through a spontaneous fermentation process combined with heating and cooling to increase the resistant starch content for use as a prebiotic food source. This study was designed as a completely randomized experiment (CRD) having 2 factors and three replications. The first factor is the spontaneous fermentation time consist of 0, 12, 24 and 36 hours and the second factor is without (0 minutes) and with 45 minutes heating. The result of length of fermentation time showed the lactic acid bacteria grow well during 36 hours fermentation, reaching 8,6 log cfu/ ml. Spontaneous fermentation process alone aid no effect on the physicochemical properties of flour produced, but the presence of heating and cooling process was significantly modified the physicochemical properties. Through the process of 36 hours fermentation, followed by heating at a temperature of 121oC for 45 minutes and cooling at 4 °C for 24 hours produced resistant starch content of 48.53% and in vitro starch digestibility 21,94%.

Abstract

Abstract Obesity is a serious illness that can cause emotional and social problems. A person is said to be overweight if the body is 10% to 20% normal body weight, while someone is called obese when overweight reaches more than 20% of normal body weight. Obesity is currently a world problem even WHO declares it a global epidemic (WHO, 2016) Meanwhile, children up to adolescents aged 5-18 years are classified as obese if the Z-Score BMI / U shows a number greater than 2 (WHO, 2016). This study was used with observational analytical research method with a research design used case control. The results showed that the picture of food energy intake and physical activity with the incidence of obesity in elementary school children was 39.3%, while for non-obese children it was 60.6%. Food energy intake in obese elementary school children is based on the level of adequacy of energy needs divided into 2 normal variables and more by 50%. And normal is 50%. There is a relationship between physical activity and the level of adequacy of energy and value (p = 0.000).Keywords: Obese, Energy Intake, Physical Activity
