Vermouth is a type of fortified wine infused with various citrus, herbs, and spices. The
researchers used pineapple peel and cornhusk to support sustainability while promoting the
first local vermouth in the Philippines. This research paper summarizes the vermouth using
pineapple peel and cornhusk and verifies its overall acceptability. It also includes methods
for analyzing the wine such as using Inductively coupled plasma, while also using
petrifilm, Pycnometer - calculated, oven-drying, gravimetric, Kjeldahl method, acid
hydrolysis, computation, refractometry and using glass electrode, and lastly was by visual
inspection and sensory evaluation. In Heavy metals test, the cadmium, lead, mercury, and
arsenic used by inductively coupled plasma resulted in not detected. In Microbial test the
standard plate count used by Petri film resulted in 620, the coli form count used by petrifilm
resulted in <10 and the E. coli which also used petrifilm also resulted in <10. The alcohol
by Volume resulted used a Pycnometer - calculated which resulted at 16.91% per 350 mL.
In moisture used by oven-drying at 105°C resulted in 91.99, then the ash used by
gravimetric method resulted in 0.22, crude protein used by kjeldahl method resulted in
0.37, for total fat used by acid hydrolysis resulted in not detected, then calories used by
computation resulted in 31.16, total soluble solids used by refractometry resulted in 12.00
and lastly the pH value at 25°c used by glass electrode resulted in 3.98. Texture used by
sensory evaluation resulted in light, warm like with slight sweet mouthfeel in the end. The
overall general acceptability of the Vermouth using pineapple peel and cornhusk from the
researcher's respondents resulted in 8.18 which is equivalent to "Like Very Much"
therefore deducing the products overall safety to consume when drinking.
