Hard Candy Production and Quality Parameters: A review.

Area of Science:

• Food Science
• Confectionery Technology

Background:

• Hard candies are sugar confections primarily made of sucrose and water.
• Production involves high-temperature heating and cooling to achieve a stable glassy state, ensuring a long shelf life.

Purpose of the Study:

• To provide a general overview of hard candy production methods.
• To examine process parameters and quality attributes affecting hard candy characteristics.
• To review existing literature on hard candy production and storage.

Main Methods:

• Literature review of hard candy production processes.
• Analysis of factors influencing physicochemical, textural, and sensory properties.
• Discussion of storage conditions and their impact on product quality.

Main Results:

• Production methods, parameters, formulations, and storage conditions significantly influence hard candy quality.
• Temperature and humidity during storage can lead to undesirable graining and stickiness.
• Even minor changes in production can substantially alter final product characteristics.

Conclusions:

• Optimizing both production and storage conditions is crucial for desirable hard candy properties.
• A comprehensive understanding of these factors is essential for consistent product quality.
• This review offers a broad perspective on hard candy science, unlike more specific existing reviews.
