3.2. Assessment of the Accumulation of Capsaicinoids at Two Ripening Stages in Chiltepin Fruits. The pungent metabolites
in the fruits of Capsicum species are called capsaicinoids, which are a group of 12 or more alkaloids with a structure
of vanillylamide of branched fatty acids with 9–11 carbons [36], but capsaicin and dihydrocapsaicin are responsible for
more than 90% of the pungency [37]. The capsaicin content in chili peppers is variable and ranges from 0.1 to 1% of the
fruit weight approximately, but the amount varies depending on the temperature at which the plant is grown, the age of
the fruit, the light, and soil composition [32].The addition of mineral supplements to the pepper crops causes an increase
in the capsaicinoid content of the fruit [38] and this nitrogen supply is essential for the synthesis of such compound
[39]. However, due to adverse effects of chemical fertilizers, interest has been stimulated for the use of organic manures.
Vermicompost is produced by biodegradation of organic material through interactions between earthworms andmicroorganisms [40].
