Introduction:

Stevia rebaudiana extracts can be used as a sweetener due to their glycoside content: specifically stevioside and rebaudioside. Both compounds have adequate pharmacological characteristics for human consumption.

Objective:

the aim of this study was to standardize the formulation of marmalades using nopal-pineapple-stevia aqueous extract ratios.

Methods:

the products were evaluated to determine their physicochemical properties, in vitro inhibition of α-amylase and glycemia in healthy volunteers. Storage study was conducted for 20 days at room temperature 23-30 °C and relative humidity 80-85%.

Results:

incorporation of stevia significantly modified physicochemical properties like °Brix, color and flow index. After storage, the presence of molds and bacteria were not detected. Sensory evaluation indicated that marmalade with 50% stevia replacement was equally accepted as marmalade with sucrose. Marmalade with 50 and 100% of stevia inhibited 35.89 and 38.50% of the α-amylase activity. After an intake of 30 g, it seems that marmalades with stevia had a significant effect on the glycemia of the volunteers.

Conclusions:

however, further studies with larger doses of nopal-pineapple-stevia marmalade and consumed for longer in both healthy volunteers and patients with diabetes are needed to achieve results that are more precise.
