올리고당과 옥수수전분의 배합비를 달리하여 제조한 김(Pyropia tenera) 스낵의 품질 특성 = Quality Properties of Laver Pyropia tenera Snack with Different Mixing Ratios of Oligosaccharide and Corn Starch

다국어 초록 (Multilingual Abstract)

Laver Pyropia tenera snack is typically manufactured as an attached laver and carbohydrate-based rice papers or glutinous rice paste. Carbohydrates contribute to a crispy texture and many various additives are used for development of texture. Isomalto-oligosaccharide (IMO) and corn starch (CS) are typical additives in snack products that produce several changes, including texture. We investigated physicochemical properties of laver snacks prepared using IMO/CS ratios of 1:0 (Sample 1), 3:1 (Sample 2), 1:1 (Sample 3), 1:3 (Sample 4), and 0:1 (Sample 5). All of the prepared laver snacks displayed constant drying rates up to 45 minutes. Samples 1 and 5 had higher drying rates than the other laver snacks. Concerning CIE color values, Sample 5 displayed the highest brightness (L*) value (78.89) and lowest yellowness (b*) value (6.66). In contrast, Sample 1 displayed the lowest L* value (74.65) and highest b* value (17.23). The hardness proportionally decreased along with IMO content. In the sensory evaluation, overall acceptance was highest for Sample 1 with the highest oligosaccharide content.
