Abstract

A large amount of phenolic compounds in sweet potato leaves are a potential source of antioxidants. However, polyphenol is sensitive under certain food processing, thereby needs innovation such as microencapsulation to maintain its stability. This study aimed to determine the encapsulation efficiency and characterization of microencapsulation of sweet potato leaf extract using maltodextrin (10% and 20%) combined with Konjac glucomannan (0.5%; 0.75% and 1%). The method used was spray drying using 120 oC inlet temperature. The result showed that the total phenolic compound of sweet potato leaves was 685.06 GAE mg/g extract. The antioxidant activity of sweet potato leaf extract with the DPPH method was 52.80% with an IC50 value of 26.73 ppm. The highest antioxidant activity of the microencapsulated powder sample (10% maltodextrin: 0.75% glucomannan) was 66.84% at a concentration of 100 ppm which had the greatest percent encapsulation efficiency (89.91%).The particle size distribution showed that encapsulated sweet potato leaf extract has a micro-size of around 0.296 µm (78.3%) with good homogeneity of the particle size which can be seen from the Pdi value of 0.304. Therefore, encapsulated sweet potato leaf with 0,75% glucomannan and 10% maltodextrin has the highest encapsulation efficiency and good characteristic.

Abstract

The utilization of native cassava starch in the food industry is limited. It needs a modified process to increase its utilization. This study aimed to evaluate the effect of a combination of steaming and acid hydrolysis and determine the best temperature and hydrolysis time that is suitable to apply as an encapsulant in the nanoencapsulation process of cocoa leaf crude extract. Modification of cassava starch used 50 ℃, 60 ℃, and 70 ℃ temperatures for 30, 60, and 90 minutes with HCl pH 1. The result showed that modified cassava starch produced from a combination of steaming and acid hydrolysis at 70℃ for 30 minutes has the best specifications with 60.48% solubility, 12.38% hygroscopicity, pasting profile (PV=48; BV=3; FV=66; SV=21). Then, it is combined with Arabic gum and used in the nanoencapsulation process using spray drying. This study showed that encapsulation can protect phenolic compounds of cocoa leaf crude extract resulting brownish-red color surrounded by a black circle. Nanocapsule powder has 13.56% moisture content, 350.3 nm particle size, 16.93 zeta potential, and 84.30% encapsulation efficiency. The combination of steaming and acid hydrolysis at 70 ℃ for 30 minutes produces modified cassava starch which is suitable for use as an encapsulant in the nanoencapsulation process of crude extract of cocoa leaves.

Abstract

Lokio (Allium chinense G Don) is widely used as seasoning in cooking because it contains amino acids that contribute to taste. Lokio is easily damaged during physical and chemical storage, affecting its quality. The study aims to determine the chemical changes of lokio leaves during storage. This study used a randomized design group with 3 temperature treatments, namely room temperature (30 ⁰C), air conditioning (20 ⁰C), and refrigerator (10 ⁰C). Weight loss was tested using a digital scale, color was tested using a chromameter, water content was tested using thermogravimetry, fat using Soxhlet, protein using Kjeldal, and ash using a muffle furnace. Reducing sugars were tested using the DNS method, amino acids using HPLC, and volatile compounds using GC MS Headspace. The data was analyzed using ANOVA then continued with Duncan test if the treatment has a significant difference (p < 0.05). In the room temperature treatment, the best treatment was obtained for 2 days of storage, AC storage for 4 days, and refrigerator temperature for 14 days of storage. Of all the best treatments for each storage temperature, the best treatment was obtained in the storage treatment using AC temperature (20 ⁰C) for 4 days. The treatment found that Lokio has a water content of 92.247%, fat of 2.47%, protein of 19.05%, ash of 14.20%, carbohydrates of 64.28%, and reducing sugar of 11.24 mg/ml. The major volatile compound content of the total storage is trimethyl sulfide and glutamic acid is the most amino acid in lokio leaves.

Abstract

Green tea in Indonesia has an astringent and bitter taste due to its high catechin content. Adding amino acids and reducing sugars in green tea processing will increase the desirable flavor and cover the astringent and bitter flavors by increasing the Maillard reaction. Research on the manufacture of green tea with the addition of glutamate and fructose in fresh tea leaves has never been explored. This study aims to find a combination of glutamic acid (0%, 0.35%, 0.7%, 1.05%, 1.4%) and fructose (0%, 0.13%, 0.26%, 0.39%, 0.52%) to improve the flavor profile in green tea. The samples were evaluated for their antioxidant activity, amino acid, volatile, sensory evaluation, and color analysis. The results showed that adding glutamate and fructose increased the antioxidant activity of amino acid compounds and decreased the catechin content in green tea. Thus, the best treatment obtained was glutamate (1.05%) and fructose (0.26%), which increased the Maillard reaction in the formation of flavor compounds in green tea.

Abstract

Sliced eggplant was pretreated (blanching and citric acid dip), -dried (oven and sun), then pulverized to flour. Physicochemical and antioxidant properties were evaluated using standard methods. The results showed increases in protein, moisture, fat, ash, crude fiber, and carbohydrate contents. They ranged from 7.78–8.39%, 8.90–10.14%, 4.32–5.28%, 0.77–0.91%, 10.72–13.43%, and 63.35–65.77%, respectively. Citric acid treatment and dried methods increased the minerals content for sodium (121.77–125.87 mg/100g), zinc (3.18–5.77 mg/100g), potassium (489.53–628.58 mg/100g), magnesium (68.86–75.39 mg/100g) and iron (8.91–11.82 mg/100g) than the blanched treatment. Functional properties of eggplant flour revealed that bulk density (0.42–0.50%,), oil absorption capacity (0.64–4.85%), and wettability (1.43–4.35%,) increased with citric acid and sun-drying method while swelling index (1.25–1.61%) and water absorption capacity (3.85–5.61%) increased with citric acid and oven drying method. Total polyphenol (26.49–29.78 mg GAE/mL), flavonoid (22.12–11.38 mg QE/mL), ABTS (52.38–61.34 Mmol/100 mL), DPPH (62.78–68.48%) and FRAP (58.67–65.36 Mmol/100mL) showed significant (p<0.05) increases in citric acid and dried methods. From the results, the physicochemical and antioxidant properties of eggplant flour were positively affected by citric acid pre-treatments in sun and oven-dried methods.

Abstract

Lead confers deleterious damage to the cells and it is necessary to explore further and develop a more effective way to ameliorate lead toxicity. This study aims to investigate how honey and Moringa oleifera (MO) can synergistically provide a more effective way to ameliorate lead toxicity. Groups of ten fish (Clarias gariepinus) were given Pb (0.30 g) and supplemented feed (T1) containing both honey (5 g) and MO (5 g). Others received pb (0.30 g) and supplemented feed (T2) containing either honey (10 g) or (T3) containing MO (10 g). Finally, hematological and biochemical analysis were conducted and a decline in the hematological parameters was observed. Also, the level of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), urea, creatinine, and malondialdehyde (MDA) significantly increased while glutathione (GSH) and superoxide dismutase (SOD) reduced in the group given lead only. However, these biochemical indices and hematological parameters are greatly restored in the group that received both honey and MO compared to the group that received either honey or MO. The findings of this study reveal that co-administration of both honey and MO synergistically damages caused by lead-induced toxicity better.

Abstract

A comparative antifungal efficacy study of argan kernels was performed using different solvent fractions obtained by the two extraction methods: cold extraction by maceration at room temperature (1) and hot extraction by Soxhlet apparatus (2). Results demonstrated that the two extraction methods induce different yields among each solvent used. Maceration promoted the maximum contents of crude extract in hexane (42.15%), diethyl ether (2.59%), dichloromethane (4.22%), and ethyl acetate (2.52%). Whereas the hot extraction yielded higher extractives in the case of methanol (22.97%) and water (5.88%) compared to cold extraction. The MIC values of the fractionated extracts obtained by maceration were in the range of 0.051 ± 0.002 and 0.223 ± 0.005 g/ml, whilst they were in the range of 0.101 ± 0.002 and 0.286 ± 0.005 g/ml for the Soxhlet extracts. According to total activity (TA) interpretation, dichloromethane was the most effective solvent to extract active antifungal components, revealing the strongest ability to suppress the growth of fungi at much lower MIC values (0.051 ± 0.002 to 0.156 ± 0.005 g/ml) than the rest of fractions. The effect of heating resulted in an increase of the MICs values of the Soxhlet extracts from 10 to 25 times higher than macerated ones, resulting in lower antifungal activity.

Abstract

Ulva lactuca is a functional food ingredient with high antioxidant content. The presence of heavy metal contaminants in natural Ulva lactuca needs to be eliminated. Ulva lactuca was investigated for its potential as a nephroprotector in female Wistar rats. The study assessed Blood Urea Nitrogen (BUN) levels, creatinine levels, and kidney histopathology. The experiment included a Group I (control), Group II (administered 1000 mg/Kg BW/day of natural Ulva lactuca), and Group III (administered 1000 mg/Kg BW/day of heavy metal decontaminated Ulva lactuca using bilimbi juice). After 30 days of oral treatment, no significant differences were observed in BUN levels before and after treatment. However, significant variations were found in Group III compared to the Group I creatinine levels after treatment. Both natural and heavy metal decontaminated Ulva lactuca showed no adverse effects on kidney function. Notably, heavy metal decontaminated Ulva lactuca exhibited improved kidney histopathology, suggesting its potential as a nephroprotector. Further research is needed to explore its broader applications in promoting kidney health.
