Abstract

Candlenuts can be used as a substitute in producing chocolate spread due to their high-fat content. However, the limitation of using candlenut in the spread formulation is the existence of a bitter taste. This study aimed to investigate the effect of sodium bisulfite and sodium bicarbonate soaking treatment (100, 300, and 500 ppm) on reducing the bitter taste of candlenut seed. In order to reach the goal, bitter compounds of candlenut and chocolate spread were identified using Liquid chromatography-mass spectrometry (LC-MS). The sensory characteristics of chocolate spread were profiled using the Rate All That Apply (RATA) descriptive method. It was shown that the panelists identified 14 sensory attributes in the samples, one of which was bitter taste. Treatment with sodium bisulfite, as well as sodium bicarbonate at the level of 300 ppm, reduced the intensity of the bitter taste. The treatment reduced flavonoid and tannin levels by 85.21% and 82.08% in candlenut seeds. It also reduced flavonoid and tannin levels by 88.47% and 72.71% in chocolate spread, respectively. LC-MS identified 13 compounds that cause the bitter taste, namely quercetin, oleuropein, kaemferol, resveratrol dimer, luteolin, epicatechin, theobromine, caffeine, iso-humolones, colaflavone, chlorogenic acid, feruloyl-caffeoylquinic acid, and coumaroylquinic acid. This study creates a new technique for producing chocolate spread formulated with candlenuts with lower bitterness levels.

Abstract

Introduction: Chocolate is a widely consumed food, particularly by children. It is often considered a contributing factor to the development of dental caries due to its high sugar content, which can lead to the formation of dental caries. Aim: This study aimed to determine whether consuming dark chocolate sweetened with sucrose, xylitol, and stevia would reduce saliva acidity in children aged 10-12 years. Methods: Twenty-one children aged 10-12 years were given dark chocolate with three sweeteners: 30% sucrose, 30% xylitol, and 1% stevia. The subjects' saliva was collected 10 minutes after chewing chocolate with sucrose on day 1, chocolate with xylitol on day 2, and chocolate with stevia on day 3 for 30 seconds and then measured by a pH meter. The measurement was repeated thrice. Result: The difference in mean saliva pH before and after treatment with the three types of chocolate were analysed using the One-way ANOVA test.  A decline in pH was observed in all treatment groups; however, the most significant decrease was observed in the sucrose chocolate group (0.34 ± 0.12), followed by the stevia chocolate group (0.26 ± 0.09), and the least significant decrease was observed in the xylitol chocolate group (0.14 ± 0.07). Conclusion: A statistically significant difference was observed in the decrease in saliva acidity among children aged 10-12 years who consumed dark chocolate containing sucrose, xylitol, and stevia

Abstract

Increasing the Resistant Starch (RS) level in food products containing naturally high starch content is important as RS has been acknowledged as a functional food ingredient. The purpose of this study is to determine the effect of steam-cooling treatment on the characteristic of arrowroot starch and to investigate the feasibility of arrowroot-based RS application on wet noodles. The study used a Completely Randomized Design (CRD) with one factor which was the steam-cooling cycle. Later, the substitution of 5%, 10%, and 20% of modified arrowroot starches on wet noodles was used, and then the consumer test was carried out. The results showed that the RS content of arrowroot starch remained after steam-cooling treatment. The treatment, however, reduced the water content and the brightness of the starch. Subsequently, arrowroot starch substitution without or with modification also reduced the lightness and tensile strength of wet noodles. Also, wet noodles with modified arrowroot starch substitution were significantly different in color, taste, and aroma parameters but were still acceptable to the panelists at a maximum substitution of 20%. The formulated wet noodles with modified arrowroot starch contained RS of 34.02% (d/b), and therefore they can be categorized as foodstuffs with high RS levels.

Abstract— Zingiber officinale Roscoe (ginger) contains a high concentration of bioactive phytochemicals, which are desirable because of their important properties. The choice of suitable extraction methods is essential for practical applications of the bioactive compounds as it determine the properties of the extractable compounds. Several customary methods have been widely used by the scientists to extract the bioactive compounds of ginger. In this paper, a critical analysis of relative advantages and disadvantages was carried out for 6 types of extraction processes namely hydrodistillation, maceration, Soxhlet extraction, solvent-solvent extraction, decoction and infusion. This review discusses the different conventional methods, followed by a discussion of the importance of advancing the extraction techniques considering the environmental benefit and efficiency of the process. The application of innovative developed technologies is deemed environmentally beneficial, more efficient in terms of extraction yield and eliminate the issues connected with traditional extraction processes. The advanced extraction techniques discussed in this paper include microwave-assisted extraction, ultrasound-assisted extraction, enzyme-assisted extraction and supercritical fluid extraction. The technical data that are available in this review paper are beneficial for the scientist and the industry who work with ginger extraction. A clear direction of future studies is offered in this paper in which researchers must investigate the possibility of applying the advanced extraction method for retrieving bioactive compounds from ginger as well as study degrading effects of each new technique on phytochemical compounds and their metabolites intermediates.

Abstract

This study aims to enhance the effectiveness of the Quality Function Deployment (QFD) method for food product development by integrating the Kano model and sensory profile analysis using Quantitative Descriptive Analysis (QDA) into the House of Quality (HOQ) matrix. The Kano model was applied to identify and categorize customer expectations, while QDA was used to characterize the sensory attributes of four steamed brownie samples—one of which was the target for improvement. Twelve quality attributes were identified, comprising both intrinsic (taste, aroma, texture, appearance) and extrinsic (packaging, labeling, branding, distribution) factors. Kano analysis revealed that two attributes were classified as Attractive, eight as One-dimensional, and two as Indifferent. Sensory profiling showed key differences between the developed product and a superior competitor. HOQ analysis indicated that improvements in formulation (composition of ingredients) and packaging design were critical for increasing consumer satisfaction. Unlike conventional QFD, which primarily translates customer requirements into technical specifications, the proposed integrative approach explicitly distinguishes attributes based on their impact on satisfaction (via Kano) and links them to measurable sensory characteristics (via QDA). This combination provides clearer prioritization and more actionable insights for product developers. Therefore, this study offers a structured and consumer-focused strategy that strengthens QFD’s applicability in the food industry by improving both accuracy and relevance in decision-making.
