Desenvolvimento de uma panqueca com biomassa de banana verde e seu efeito agudo em sinais subjetivos de fome e saciedade

Abstract

Green banana is known for its high fiber content as well as for a starch concentration that is not digested or absorbed by the intestine. Studies suggest that consumption of green banana biomass, possibly due to the high content of starch resistant, can generate health benefits, such as reduction of glycemia, colon’s fermentation by bifidobacteria, production of short-chain fatty acids, increased fecal and prevention of some types of cancer. The objective of this study was to evaluate if the consumption of meal based on green banana biomass impacts on the subjective signs of hunger and satiety and subsequent food consumption. The pancake with biomass was developed and evaluated sensorially by 60 untrained tasters, using the hedonic scale of nine points, with a score varying in Dislike Extremely and Like Extremely. For the evaluation of the subjective signs of hunger and satiety, a randomized and cross-over trial was conducted in which 36 adult and eutrophic women participated in the study, receiving two pancakes containing 60 grams of green banana biomass and 2,6 grams of starch resistant, with organic strawberry syrup or the control pancake (without green banana biomass). The levels of hunger and satiety were analyzed through a Visual Analog Scale (VAS) before, 30, 60, 120 and 180 minutes after ingestion. Subsequent food consumption was analyzed by offering an ad libitum lunch. The results of the sensorial analysis showed that was a good acceptance in both pancakes but the sample containing green banana biomass was the best evaluated by the tasters in all the attributes. Regarding the clinical study, the results showed that there was no significant difference between the parameters of hunger and satiety and consumption in none of the meals offered. It was concluded that breakfast enriched with green banana biomass, rich in resistant starch, was not able to alter the subjective signs of hunger and satiety nor to reduce the subsequent food consumption among the eutrophic women selected to participate in this study. Therefore, more studies are necessary to increase knowledge about the specific topic.
