Sensory Research on Ginseng Food Products
type: CreativeWork
description: Ginseng food products in the United States have mostly been restricted to beverages despite numerous pharmacological effects of ginseng and the growth of functional foods market. Few consumer sensory studies related to ginseng have been conducted in the United States. The overall objectives of this study were to: 1) probe U.S. consumers’ insights of ginseng food products, 2) determine the sensory acceptance of ginseng food products, and 3) characterize the changes in the sensory properties of coffee and chocolate bitterness by the addition of ginseng extract. Three independent focus groups (n = 14) identified that panelists had little experience in consuming ginseng food products. Due to their unfamiliarity with ginseng, informative packaging including more health claims was recommended. The proposed ginseng food product types to be developed to target the U.S. market included ginseng chocolate and coffee. Addition of sweeteners and fruity and spicy flavors was recommended to reduce bitter and earthy flavors innate to ginseng. Conjoint analysis (n = 400) identified that consumers had a low initial interest in ginseng food products. “Sweetness” and “ginseng chocolate” elements drew consumers’ interest, while “bitterness” and “earthy flavor” elements detracted from consumers’ interest. Ginseng chocolate was identified again as a potential product for success in the United States. When commercial ginseng products were evaluated by a consumer panel (n = 126), Korean red ginseng candy with vitamin C and Korean red ginseng crunchy white chocolate were the most highly accepted. When ginseng was tested in model tea and chocolate systems, consumer acceptance increased with increasing content of sugar and honey in ginseng tea, whereas acceptance decreased with increasing content of ginseng extract in milk and dark chocolates. To assess the masking effect of peculiar ginseng tastes by other bitter compounds, a descriptive analysis (n = 12) including time-intensity ratings was …
