The Impact of Herbs and Spices on Increasing the Appreciation and Intake of Low-Salt Legume-Based Meals

Abstract

Flavoring using blends of herbs and spices (H&S) instead of salt may be a promising approach to increase legume consumption and reduce salt content in foods. This study examines the effects of H&S on the appreciation and intake of low-salt legume-based dishes in a real ecological eating environment. Four mezzes with standard (0.8% w/w) (S) or lower (0.4% w/w) (LS) salt level and with or without H&S (LSHS, SHS) were developed. In a randomized cross-over trial, 94 participants attended four sessions, one week apart and received the four variants as a starter during lunch. Overall liking, food intake, and appetite ratings (visual analogue scale, VAS) were assessed during lunch. A follow-up study (n = 130) was performed where the four variants were evaluated, and overall liking was measured at the same session. Overall liking and taste scores of SHS were significantly higher compared with LS (p = 0.04 and p = 0.03, respectively), but there were no significant differences between LSHS and S. However, there were no differences in energy intake or in appetite ratings among the products. Overall appreciation was similar between the low-salt with H&S and the standard-salt mezze, suggesting that the addition of H&S is a feasible strategy for achieving a 50% reduction in salt content without compromising hedonic appreciation.

Development of a Danish Adapted Healthy Plant-Based Diet Based on the EAT-Lancet Reference Diet

“…This highlights the need of the food industry to lower the content of salt in processed foods and in food service to make sure that the current high salt content found in the average diet is not "transferred" to a plant-based diet [61,62]. A recent study showed that the addition of herbs and spices is a feasible strategy for achieving a 50% reduction in salt content without compromising hedonic appreciation [63]. Excess dietary sodium has been found to have a major role in the pathogenesis of hypertension, a leading risk factor for premature death in the world, as it has an effect on blood pressure.…”

Genetic variability and genome-wide association analysis of flavor and texture in cooked beans (Phaseolus vulgaris L.)

“…Flavor and texture are characteristics that consumers consider when purchasing dry beans, influencing their decisions regarding market class and product type (Castellanos et al 1997;Scott and Maideni 1998;Leterme and Carmenza Muñoz 2002;Eihusen and Albrecht 2007;Winham et al 2019). However, for many consumers, beans are not palatable, and the beany flavor they impart when used as ingredients is often perceived as undesirable (Nachay 2017;Dougkas et al 2019). Therefore, improving dry bean flavor and texture through breeding has the potential to increase consumer acceptance and utilization of beans and inclusion of beans as ingredients in products while appealing to consumers' interest in flavor without many additives.…”

Compendium of sodium reduction strategies in foods: A scoping review

“…In plant‐based protein meals composed of legumes, the influence of various spice blends on consumer acceptance was investigated as the salt content was reduced. Mean overall liking and relative mean taste liking were higher for the treatments containing the cumin spice blend, compared to their same salt spice‐free blend counterpart (Dougkas et al., 2019).…”
