This study explored a new distilled spirit made from prickly pear fruits and Cypriot grapes. The prickly pear addition enhanced bioactive compounds and consumer preference, especially for the yellow variant spirit.
Area of Science:
- Food Science and Technology
- Beverage Science
- Agricultural Chemistry
Background:
- Traditional grape-based spirits like zivania are popular in Cyprus.
- Prickly pear (Opuntia ficus-indica) is a fruit with potential bioactive properties.
- Exploring novel ingredients can enhance the quality and appeal of distilled beverages.
Purpose of the Study:
- To develop a novel distilled alcoholic beverage using prickly pear fruits and Cypriot grape varieties.
- To evaluate the physicochemical, bioactive, mineral, volatile, and sensory properties of the new spirit.
- To compare the characteristics of spirits made with yellow and red prickly pear variants.
Main Methods:
- Fermentation of prickly pear fruits (yellow and red) with Mavro and Xynisteri grape varieties.
- Traditional distillation to produce two spirit variants (45% and 59% v/v alcohol).
- Comprehensive analysis including physicochemical properties, antioxidant capacity, methanol, phenolics, flavonoids, minerals, volatiles, and sensory evaluation.
Main Results:
- Prickly pear addition improved bioactive composition, with yellow variants showing higher flavonoid content (5.56 mg/L quercetin).
- Antioxidant activity ranged from 1.00 to 1.49 mg FeSO4/L.
- Yellow (59% v/v) spirits had elevated manganese, cobalt, and nickel; red variants showed higher aluminum, platinum, and magnesium.
- Volatile profiling indicated increased esters and alcohols in 59% v/v spirits, with yellow variants rich in fruity esters like ethyl acetate.
- Sensory testing revealed a preference for prickly pear spirits, with yellow (59% v/v) achieving 9.7/10 for overall acceptability.
Conclusions:
- Prickly pear fruits can significantly enhance the chemical composition and sensory attributes of grape-based distilled spirits.
- The yellow prickly pear variant, particularly at 59% v/v alcohol, shows promising potential for creating a complex and preferred beverage.
- This novel approach offers opportunities for product innovation in the distilled spirits industry.

Preparation of Alcohols via Addition Reactions
The acid-catalyzed addition of water to the double bond of alkenes is a large-scale industrial method used to synthesize low-molecular-weight alcohols. An acidic atmosphere is required to allow the hydrogen in the water molecule to act as an electrophile and attack the double bond in an alkene. The addition of a proton to the double bond creates a carbocation intermediate. The proton preferentially bonds to the less substituted end of the double bond to create a more stable carbocation...

Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...
Fermentation
Fermentation is a type of metabolic process that occurs in the absence of oxygen, where organic molecules such as glucose are broken down to produce energy. During this process, the...
Preparation of Diols and Pinacol Rearrangement
The reaction begins with transferring a proton from the acid catalyst to one of the hydroxyl groups, producing an oxonium ion.
