Abstract

Coffee is rich in phenolic compounds, which can be evaluated by the total phenolic or specific individual phenolics. The composition and concentration of phenolics in coffee are affected by various factors, including postharvest and roasting. This study aimed to compare the ratio of phenolic acid (measured as chlorogenic acid) to total phenolic in Bogor arabica coffee, considering different postharvest treatments and roasting levels. The coffee samples were treated with different postharvest (dry, wet, and honey) and roasting processes (light and dark). Green coffee bean was used as a control. The roasting process involved heating the coffee at temperatures ranging from 147.9 to 178.8°C for light roasting, and 190.2 to 200°C for dark roasting (10 minutes each). The color of the coffee beans, concentration of phenolic acid in the coffee extract, and total phenolic in the coffee extract were analyzed using a colorimeter, HPLC, and spectro-photometer respectively. The results showed that roasting significantly intensified the dark color of Bogor arabica coffee. Among the phenolic acids, the 5-CQA isomer emerged as the most dominant and was also the most susceptible to degradation during roasting. As the roasting level increased, the concentration of phenolic acid consistently decreased. Interestingly, the total phenolic initially increased in light roasted coffee but decreased in dark roasted coffee. Green coffee beans exhibited the highest proportion of phenolic acid (83%), whereas dark roasted coffee had the lowest proportion (19%). Although light roasted coffee had the highest total phenolic, its phenolic acid concentration decreased significantly compared to green coffee beans.

Abstract

Tempe is a nutritious, healthy, and affordable food. Tempe production is simple, but less hygienic under traditional production, therefore can have inconsistent quality, safety, and reduce consumer interest. In Indonesia, Good Manufacturing Practices (GMP) implementation is a basic requirement for food industries, including tempe industries, in producing safe food products. It is yet unknown the availability of GMP tempe, especially in Jabodetabek area and how it relates to consumers' willingness to purchase. This study aimed to determine the availability of GMP tempe in Jabodetabek and to analyze the knowledge, perceptions, and willingness of Jabodetabek consumers to purchase GMP tempe. The research method included observing the GMP-applying tempe availability and surveying consumers' knowledge and willing-ness to purchase GMP-applying tempe using google form questionnaire. Data analysis used descriptive and Spearman correlation test. The results showed that GMP-applying tempe was available in almost half (38%) of market sample in Jabodetabek. GMP-applying tempe was available in small number (1%) of traditional markets and most (72%) supermarkets. Most of the respondents (54%) were used to consuming good quality tempe. Almost all respondents (78%) understood the advantage of GMP-applying tempe. Most respondents (67%) were willing to purchase GMP-applying tempe with a maximum price increase of 20% from regular tempe.

Abstract

Coffee contains abundant bioactive compounds related to health, among which are phenolic acids and diterpenes. This study aimed to investigate phenolic acids and diterpenes content in Arabica Gayo coffee, and its in-vitro antioxidant activities due to different brewing methods. The manual brewing methods used were tubruk (steeping), V60 drip, and hanging drip bag. The analysis conducted was determination of phenolic acid content as chlorogenic acid isomers (as 3-caffeoylquinic acid (3-CQA), 4-caffeoylquinic acid (4-CQA), and 5-caffeoylquinic acid (5-CQA)), diterpenes content (as cafestol and kahweol), and antioxidant activity using DPPH and FRAP method. The result showed that tubruk brew had 3-CQA, 4-CQA, and 5-CQA content of 0.38, 0.45, and 1.11 mg/mL, respectively, while V60 brew contained 0.39, 0.45, and 1.18 mg/mL, respectively. They were significantly higher than those in the drip bag, 0.25, 0.33, and 0.85 mg/mL, respectively. Cafestol and kahweol content in tubruk were significantly higher, reaching 3.03 and 7.86 mg/L consecutively, as in V60 were 0.40 and 1.02 mg/L and in drip bag were 0.46 and 0.85 mg/L. DPPH result displayed no significant difference per sample volume (918.45-921.17 mg ascorbic acid equivalent/L). FRAP result showed tubruk brew has the highest activity with 635.12 mg gallic acid equivalent/L, compared to V60 and drip bag brew at 560.91 and 551.10 mg gallic acid equivalent/L, consecutively. The results revealed that brewing methods affect the bioactive content of the final brew, in this research were phenolic acids and diterpenes. Various methods may differ in the variety and amount of other extracted bioactive compounds, so which affects the antioxidant activities of coffee brew.

Abstract

Pineapple skin, a by-product of the pineapple industry in Lampung, has significant potential for utilization. Pineapple peel extract can be used as a fermentation medium for nata de pina, thereby enhancing its added value. The production of nata de pina requires a nitrogen source that is safe for human consumption and poses no food safety risks. Legume sprouts, such as mung bean and soybean sprouts, have the potential to serve as nitrogen sources in the production of nata de pina. This study aimed to investigate the effect of varying concentrations of nitrogen sources from mung bean or soybean sprouts on the properties of nata de pina, including pH, total acidity, thickness, yield, moisture content, crude fiber, ash content, and sensory attributes (color, aroma, texture). Mung bean and soybean sprout juices were used at two concentration levels, 25% and 50% of the volume of pineapple peel juice (v/v). Data were analyzed using One-Way ANOVA with a 5% significance level, followed by DMRT if significant effects were observed. Nata de pina produced with the addition of 50% soybean juice demonstrated optimal results, with a thickness of 1.4 cm, yield of 67.5%, moisture content of 97.7%, crude fiber of 2.2%, and ash content of 0.16%. The sensory evaluation revealed scores of 4.26 for color (like), 2.92 for aroma (moderate), 3.78 for texture (like), and 3.78 for overall preference (like).

Abstract

Declining COVID-19 positive case does not reduce food industry, especially ready to drink (RTD) beverages industry, to sell product with vitamin C claim. Furthermore, increasing air pollution and climate change has encouraged consumers to maintain their immune system. Meanwhile, RTD beverages are well known as calorie drink with its high sugar content, hence could increase risk of type 2 diabetes. This research aims to evaluate sugar type, sweetener type, sugar and vitamin C content, and vitamin C claim which stated on the label of vitamin C claimed RTD beverages (food category 14.1.4.1 and 14.1.4.2) that is sold in various minimarket and supermarket in Bogor area, and online shop during February to May 2023. Total sugar content subsequently compared to front of pack (FoP) labelling guidance from United Kingdom (UK), Singapore, and Indonesia. This research has collected 70 samples, that consists of fruit juice drink, fruit flavored drink, fruit drink, tea drink, jelly drink, carbonated flavored drink, and milk flavored drink. As much as 74.28% among the samples contained sugar, mainly from sucrose, above 6 g/100 mL. Besides sugar, 52.74% samples contained sweetener, with stevia as natural sweetener more used than artificial sweetener. Based on sugar FoP labelling guidance, the majority of samples was in medium (amber) category in UK, C (orange) category in Singapore, and orange category in Indonesia. Source of vitamin C was the most claim stated as nutritional content claim, while vitamin C function claim to help collagen formation and maintenance was more mentioned compared to immunity claim.

Abstract

The habitual and excessive consumption of instant noodles can have adverse effects on health, primarily due to their high salt content. Patterns of excessive salt intake in food consumption are a contributing factor to the prevalence of non-communicable diseases. The Indonesian government has issued labeling regulations regarding the inclusion of information on sugar, salt, fat content and health messages to educate the public in monitoring their daily salt intake independently. This study aims to identify the information provided on instant noodle packaging. The research comprises of inventory and identification of instant noodle packaging labels, as well as the processing of data from these labels. According to the nutrition fact, instant noodle soup has an average salt (sodium) content of 1627.65 mg/100 g and contributes to 109% of the recommended daily salt intake. Salt content in instant noodle soup is higher than in fried instant noodles. Regular instant noodle products with the code ML more frequently include warning about high sugar and salt content. The “healthier choice” instant noodles product has an average sodium level of 697.84 mg/100 g and contributes 47% of the recommended daily salt intake. The total fat, sugar and salt content of the “healthier choice” noodles are 50.63, 13.78, and 36.56% respectively lower than regular fried instant noodles. Awareness of consuming instant noodles with low fat, sugar and salt content is expected to reduce the risk of non-communicable diseases.

Abstract

Indonesia has the highest rice consumption rate in the world, averaging 130 kg per capita per year. Despite government efforts to reduce this through food diversification programs, there has been little success. One approach to reducing rice consumption is to process non-rice ingredients into rice analogues that have similar characteristics to traditional rice. The amylose content of the ingredients plays a significant role in determining the physical properties of these rice analogues. Additionally, the screw speed of the extruder used in the production process also influences these physical characteristics. This study aimed to explore the impact of extruder screw speed and material amylose content on the physical properties of rice analogues. Local corn flour was mixed with high-amylose corn starch to create mixtures with amylose contents of 16.99, 19.35, 21.72% and 24.08%. The tested screw speeds were 100, 125, and 150 rpm. The evaluated physical characteristics included the hardness of the rice analogues, bulk density, cooked rice hardness, gumminess, and sensory properties of the cooked rice. The results showed that as amylose levels increased, the hardness of the rice analogues, cooked rice hardness, and gumminess also increased. Similarly, increasing the screw speed of the extruder led to higher cooked rice hardness, gumminess, and rice analogue hardness, but it decreased bulk density. The optimal extruder operating conditions were found to be an amylose content of 21.72% and a screw speed of 100 rpm, producing rice analogues with a hardness of 3610 gf, a bulk density of 0.63 g/mL, a cooked rice hardness of 3200 gf, and gumminess of 1200 gf.

Abstract

The purple sweet potato tuber, rich in functional chemical components, offers potential for development into high-value products such as flour, which can then be processed into analog rice. This research aims to evaluate the changes in functional chemical components–namely moisture, ash, protein, fat, carbohydrates, anthocyanin, and β-carotene–along with antioxidant activity during the processing of purple sweet potato tubers into flour and analog rice. The chemical composition of the tubers was found to be as follows: moisture content of 78.00% on a wet basis (wb), ash content of 9.70% on a dry basis (db), fat content of 5.47% (db), protein content of 26.93% (db), carbohydrate content of 58.41% (db), anthocyanin content of 31.79 mg/100 g (db), β-carotene content of 17.73 mg/100 g (db), and antioxidant activity of 65.70%. The composition of the resulting flour included water (6.71% wb), ash (2.40% db), fat (1.06% db), protein (3.80% db), carbohydrate (92.75% db), anthocyanin (3.47 mg/100 g db), β-carotene (1.51 mg/100 g db), and antioxidant activity (45.59%). The chemical content of the analog rice was as follows: water (8.43% wb), ash (1.78% db), fat (1.62% db), protein (4.13% db), carbohydrate (92.50% db), anthocyanin (0.71 mg/100 g db), β-carotene (1.05 mg/100 g db), and antioxidant activity (8.38%). Processing the tubers into flour resulted in a reduction of fat, protein, anthocyanins, β-carotene, and antioxidant activity, while carbohydrate content increased. Similarly, the conversion of flour into analog rice led to decreased levels of carbohydrates, anthocyanins, β-carotene, and antioxidant activity, whereas fat and protein levels increased after transfor-mation into analog rice. The processing stages that significantly contributed to these changes in chemical components included drying, formulation, and extrusion.

Abstract

Catfish (Pangasianodon hypophthalmus) like other animal products decay quickly. The way to extend the shelf life is with edible coating which is added with neem leaf (Azadirachta indica A Juss.) extract as an antibacterial agent. The research objective was to find out the effect of neem leaf extract as an antibacterial on coated fresh catfish during cold stored. The study used a completely randomized design with two independent variables and two replications. The first independent variable was the concentration of neem leaf extract with levels of 2.5; 5; 7.5% v/v. The second was storage time of 0, 2, and 3 days. The results of the ANOVA test showed that the concentration of neem leaf extract and the duration of storage time affected the quality of catfish meat which was coated and stored in the refrigerator except for moisture content parameter. The best formulation was obtained in edible coating with a concentration of 7.5% neem leaf extract and storage time of 3 days. The quality of the coated fish had a moisture content of 72.05% db, ash 2.66% db, protein 9.33% db, fat 1.91% db, carbohydrates 14.06% db and TPC 5.57 log CFU/g. The results of the organoleptic test on fish fried without seasoning showed the color, texture, aroma and taste were pale white (ln 3,7), soft (ln 3,6), fishy (ln 3,6), and not bitter (ln 3,7) respectively, which the panelists liked.

Abstract

Indonesia is the fourth largest coffee-producing country in the world. The popularity of coffee is increasing due to people's curiosity about the origin of coffee, from harvest to the hot cup of coffee on their table. This coffee culture drives innovators to develop coffee processing technology. Currently, there are tens of different coffee brewing methods available, each with their own unique flavor characteristics. The particle size of coffee beans is the basis for brewing coffee using specific methods. Identifying the particle size and calibrating tools to grind coffee requires special skills, expertise, experience, and a time-consuming process. Therefore, this study aims to develop a tool to classify the particle size of ground coffee based on computer vision. The object of this research is ground coffee with various particle sizes, which are acquired through imagery and will be classified using Convolutional Neural Network to provide recommendations for brewing coffee according to the particle size of the ground coffee. To build the classification model, the architectures were trained by full learning and transfer learning using VGG-19, MobileNet, and InceptionV3. The results showed that the classification model using the Convolutional Neural Network using the cellphone camera dataset achieved an accuracy value of 0.80. Meanwhile, with the microscope dataset, the model's accuracy only reached 0.58. Therefore, the classification model using the cellphone dataset is feasible to be implemented to determine the particle size.
