Abstract

The limited use of cassava for industrial purposes encourages the development of various derivative products from cassava including cassava flour. However, cassava flour has unfavorable characteristics when used directly as raw material for food products so it must be modified. The aims of this study were to modify cassava flour, and to identify characteristic from several modified cassava flour. The cassava variety used was cimanggu. This study used completely randomized design (CRD) with three treatments of modification, each in triplicate. The modification methods used were spontaneous fermentation of cassava flour suspension for 36 hours (TSFS), fermentation of sliced cassava for 48 hours (TG), and heat moisture treatment of cassava flour at moisture content of 20% with temperature of 121oC for 15 minutes (TS HMT). The modified cassava flour was dried, then analyzed for amylose content, whiteness index, and pasting properties. The results showed that TSFS modification increased amylose content and pasting temperature, but it decreased the breakdown viscosity. TG modification increased the amylose content, whiteness index, viscosity (peak, final, setback), and pasting temperature, but it decreased breakdown viscosity. TS HMT modification increased pasting temperature, but it decreased viscosity (peak, breakdown, final, setback) and whiteness index.

Abstract

Diversifications of raw materials for noodle preparation using local carbohydrate sources offer considerable advantages through lowering wheat demand and providing specially-designed food such as gluten-free diet. Structural formations of gluten-free noodles substantially differ from wheat-based noodles due to the presence of gluten. Therefore, studies on starch characteristics including the ratio of amylose and amylopectin, granule morphology, and gelatinization properties are absolutely essential since they are responsible for noodle quality. Starch modification, for instance, HMT (heat moisture treatment), is a promising technique to improve starch properties for noodle preparation. Furthermore, processing conditions also account for noodle quality. Extrusions constitute an appropriate technology for the development of noodle processing technique as it gelatinizes starch and produces pressing and kneading effects that are required to form desirable noodle structure. This paper reviews current studies of gluten-free noodles and extrusion technology for noodle production.

Abstract

Pumpkin muffins are rich in fiber but have low expansion volume and high hardness. To date, research on pumpkin muffins has only been conducted on a laboratory scale. Therefore, a pilot plant study is needed to optimize its production on an industrial scale. This work aimed to determine the processing conditions that could produce the optimum quality of pumpkin muffins on a pilot plant scale. Water addition and baking time were chosen as optimization variables, color, moisture content, expansion volume and hardness were selected as response variables. Optimization was conducted using Response Surface Methodology in Design Expert 7.0® program. The mathematical models for brightness and hue were cubic models, and those for moisture content, expansion volume, and hardness were quadratic models. Optimization results with a desirability value of 0.884 were obtained from the addition of 48% water and baking time of 22 minutes. The resulting pumpkin muffins had lightness of 41.21, hue of 70.74, moisture content of 27.96%, expansion volume of 185.39%, and hardness of 2.91 N and contained 27.96% moisture, 2.23% ash, 18.59% fat, 5.85% protein, 45.37% carbohydrates, and 8.76% dietary fiber. These findings provide new insights for researchers and bakery industries to improve the quality of muffins from local food sources.

Abstract

Sensory attribute is one of quality parameter that affects buying intention of consumer for commercial instant chocolate drink product. Evaluation of consumer liking using hedonic method or ideal profile method was not enough to fulfill consumer satisfaction. This research aims to identify sensory attributes which are able to give consumer satisfaction using survey method integrated with structural equation model (SEM), Kano method, and total unduplicated reach and frequency (TURF). Kano method is used to evaluate sensory attributes based on consumer satisfaction, while TURF is used to identify sensory component which is able to increase buying intention of consumers with regard to the range and frequency for chocolate instant commercial drink. Preliminary research conducted by modelling consumer preferences suggested that there was an influence of 0.76 sensory attributes to consumer satisfaction. Seven samples were purchased from market and evaluated by 30 untrained panelists using home use test with an approach of consumer habit to consume hot chocolate drink once a week. The panelists were chosen from people who consume commercial instant chocolate drink. Results of this research showed that sensory attributes creamy (texture) and dark chocolate (color) were attractive features which were able to improve consumer satisfaction. Atribute sweet (taste) was categorized as must-be features, while flavor, aroma, and color were classified as one-dimensional features. Combination of attributes in one category can improve the range to reach the targeted consumers and frequency of consumers towards the product, for example attribute creamy can reach 97%, but combination of attributes creamy and thickness can reach 100% of the targeted consumers.

Abstract

Cocoa bean is a rich source of polyphenols, which are the largest group secondary metabolite with natural antioxidant property. Polyphenols from cocoabeans was reported to possess health benefits. Fermentation, one step in cocoa processing is needed to improve the quality of cocoa in which the concentration of cocoa bean polyphenols might decrease significantly through oxidation and exudation. Cocoa polyphenols content among different cocoa clones mightalso vary. The aims of this study were to determine total polyphenols, total flavanoid, epicatechin, and catechin content in several cocoa clones, those wereSulawesi 1, Sulawesi 2, ICCRI 03, and KW 617. Until now, characterization of polyphenols from those clones has not been reported. The effect of five daysfermentation to those parameters was also studied. The results of the study showed that fermentation and type of clones significantly affected total of polyphenols, total of flavanoids, epicatechin, and catechin content of the cocoa, there is also an interaction between fermentation and type of clones. Unfermented of Sulawesi 1 had the highest total polyphenols of 96.94±5.83 mg/g, total flavanoids of 90.92±1.89 mg/g, epicatechin of 52.50±0.46 mg/g, and catechin of 1.99±0.02 mg/g content compared to other clones. Among five days fermented cocoa beans, Sulawesi 2 showed the highest total polyphenols and total flavanoids content, while ICCRI 03 had the highest epicatechin and catechin content than other clones. Thus, in can be concluded that although fermentation is required to improve the flavor quality of cocoa, it significantly reduced the content of bioactive compounds. This effect varied amongdifferent cocoa clones.

Abstract

This study aims to develop a structural model to assess knowledge, attitudes, and COVID-19 preventive practices among food handlers (FH) and food delivery workers (FDW) in Greater Jakarta, Indonesia. Given the region's high population density, the risk of COVID-19 transmission is heightened, making preventive practices essential. Data were collected from 675 respondents using a questionnaire consisting of 36 items. The data were analyzed using partial least squares structural equation modeling (PLS-SEM). Results revealed that both knowledge (β= 0.959 for FH; β= 0.756 for FDW; p<0.05) and attitude (β= 0.546 for FH; β= 0.410 for FDW; p<0.05) positively impacted COVID-19 preventive practices. Attitude emerged as a crucial predictor, explaining a higher variance in FH prevention practices (R²= 0.346) than in FDW (R²= 0.174). The findings underscore the importance of strengthening attitudes toward preventive measures like hand washing, mask-wearing, and physical distancing, particularly among FDWs, to enhance safe food delivery practices. The structural model and insights provide a valuable framework for developing targeted interventions and strengthening public health preparedness for future pandemics or similar crises.
