Abstract

This study aimed to evaluate the effect of aromatized thin-layer biopolymers on sensory perception in gel emulsions with spatial distribution of fat. An edible coating technique was used with Wijsman butter and cheese-cheese aromas to enhance fat perception without compromising other sensory attributes. Homogeneous gels with 20% fat content were applied with scented and unscented thin-layer biopolymers and then analyzed using the hedonic organoleptic method involving hardness, suppleness, color (transparency), and aroma parameters. The results showed that the scented thin-film biopolymer improved panelists' acceptance of fat aroma perception (score of 7.8), compared to the unscented biopolymer (score of 5.5). Panelists' acceptance of hardness, suppleness, and gel transparency did not differ significantly between the flavored and unscented treatments (values ranged from 7.1 to 7.9). This suggests that the addition of aroma can improve the perception of fat without affecting the physical quality of the gel. The use of aromatized thin-layer biopolymers can be an effective strategy to improve the sensory quality of low-fat food products, which is relevant in efforts to address the prevalence of overnutrition. This study contributes to the development of healthy food technology while maintaining consumer preferences for product texture and visuals.

Abstract

Tofu dregs is an abundant waste from food production that is often not optimally utilized. In fact, tofu dregs have the potential to become an alternative food source if done in accordance with the ideal processing process and supported by the characterization of its nutritional content. This study aims to assess the chemical characteristics of tofu dregs flour through proximate analysis. The parameters analyzed included moisture content, ash, fat, protein, and carbohydrate by difference. Tofu dregs samples were obtained from tofu artisans in Bogor Regency, then dried, ground, and analyzed through the laboratory. The research was exploratory in nature using two replicates. The results showed that the moisture content of tofu dregs flour was 8.49 ± 1.34%, ash content 2.81 ± 0.19%, fat 7.86 ± 0.21%, protein 17.32 ± 0.27%, and carbohydrate by difference 63.53 ± 1.09%. The high protein content indicates that most of the soybean protein fraction is still left in the dregs. The low moisture content means the potential microbiological resistance of tofu bagasse flour during storage. These findings confirm that tofu dregs flour has promising nutritional value and it can be further developed as a sustainable ingredient for high-protein and fiber-rich food formulations. This will thereby contribute to waste reduction and functional food innovation.
