Abstract

Stunting in children is a significant problem worldwide, specifically in developing countries. One of the contributing factors to this condition is dysbiosis, characterized by an imbalance in gut microbiota and is commonly observed in affected patients. To reduce the prevalence of stunting, it is critical to provide products that are rich in protein, calcium, and probiotic. In this context, freeze-dried probiotic yogurt snacks can be used as an effective solution due to their high nutritional value, ability to preserve probiotic cell viability, and extended shelf life. Therefore, this study aims to determine snacking habits and level of acceptance of yogurt snacks among children through a sensory evaluation. The result showed that parents often considered taste, health benefits, and price when purchasing snacks. Meanwhile, children showed a high preference for freeze-dried probiotic yogurt snacks, particularly due to their appealing shape. Panelist parents also considered the products to be necessary, recommended, and an alternative to unhealthy snacks. Therefore, these products may be suitable for upper-middle-class consumers due to their higher prices and will require taste improvement to increase consumer acceptance among children.

Abstract

An alternate healthy snack for school-age children can be prepared by adding sorghum and tempeh flour, which are sources of protein and fiber, to instant cereal drinks. Probiotic-enriched snacks are well-known, and several clinical studies have shown significant benefits to humans. Therefore, this study aimed to assess the effects of various ratios of sorghum and tempeh flour (5:1, 2:1, and 1:1) on physicochemical and sensory characteristics of the flakes. The viability of Lactiplantibacillus plantarum subsp. plantarum Dad-13 in an instant cereal beverage was examined for 56 days at three distinct storage temperature, i.e 20, 30, and 37 °C. The 2:1 sorghum: tempeh flour ratio formulation was the most widely accepted. According to chemical analyses, all probiotic instant cereal drink formulations have the potential to be sources of fiber (6.4–10.6 g/100 g) and proteins (14.5–16.3 g/100 g). Furthermore, the probiotic instant cereal drink contains more fiber and protein than a commercial product. This product has a minimum viable count of probiotic bacteria > 6.0 log CFU/g, which is substantial enough to have positive health effects on Indonesian school-age children.

Abstract

Crude palm oil (CPO) is characterized by high carotenoid content, dissolving in the oil system and causing a difficult extraction process. To overcome this problem, transesterification of CPO with ethanol was performed to improve the carotenoid extractability using sodium hydroxide as a catalyst. Therefore, this study aimed to investigate the effect of ethanolysis parameters on the carotenoid and fatty acid ethyl ester (FAEE) content of CPO. FAEE content was quantified by thin-layer chromatography and total carotenoid content (TCC) was determined through a UV-Vis spectrophotometer. Reaction time (15-150 min), catalyst concentration (0.65-3.25%), reaction temperature (3070 ℃), and stirring speed (500-2000 rpm) were determined by one factor at a time (OFAT) design. The results showed that ethanolysis time and temperature did not affect TCC along the study range, while ethanolysis time of 45 minutes and temperature of 70 ℃ increased FAEE content. Additionally, catalyst concentration of 1.95% and stirring speed at 2000 rpm increased TCC and FAEE. The best ethanolysis parameters were obtained at 45 minutes, the temperature of 50 ℃, catalyst concentration of 1.3%, and stirring speed of 2000 rpm, yielding FAEE 1358±16 ppm and TCC 99.9±0.2%. This showed that ethanolysis produced high FAEE content and improved carotenoids in the oil system.

Abstract

Aspergillus flavus is a fungal species frequently contaminating nutmeg seeds. Therefore, this study aimed to prevent sporulation by introducing gaseous ozone treatment. In the process, spore suspensions (4.8 x 10 7 spore/ mL) were exposed to ozone (0-11 ppm) for 90 min. Approximately 0.5 mL of each suspension was plated on CDA and incubated at 28 °C (7 days; 24 hours for the remaining samples) alongside the remaining 4.5 mL for 24-60 hours. The results showed that the treatment has significantly delayed the spore germination up to 60 hours. A positive correlation exists between the increasing gas concentration and the lowering of germination. Furthermore,  the reduction of A. flavus load after being treated was from 0.24-1.2 log spores/mL. The efficacy of this treatment is directly proportional to the concentration of ozone. The three proposed models, including the linear log regression, the Geeraerd shoulder, and the Weibull models, were fully suitable for describing spore inactivation kinetics, emphasizing the potential of ozone as an effective antifungal treatment for microbial control.

Abstract

DOI of original article: https://doi.org/10.22146/agritech.81499Authors Correction:The authors regret a typographical error in the ABSTARCT page 41. It was written as 'yielding FAEE 1358±16 ppm and TCC 99.9±0.2%'. It should correctly read 'yielding FAEE 99.9±0.2% and TCC 1358±16 ppm'.
