20 Questions
What is the primary purpose of the conching process in chocolate making?
To develop and enhance the flavor of the chocolate
What leads to the movement of flavors during the conching process?
Initial flavor concentration gradient between different particles or phases
What occurs at temperatures above 100 °C during conching?
Flavor changes start occurring, promoting Maillard type flavors
What is the purpose of the five-roll refiner in chocolate making?
To alter the texture and viscosity of the chocolate film
How does the five-roll refiner affect the taste and texture of chocolate?
It alters the texture and viscosity of the chocolate film
What is the aim of the chocolate milling process described in the text?
To remove particles larger than 30 microns from the chocolate.
What is the difference between fine ingredient process and combined milling?
The fine ingredient process involves milling non-fat components separately, while combined milling mixes all components before milling.
What is the function of the two-roll mill in combined milling?
To pull the paste into a gap between them by turning in opposite directions.
What is important to achieve before the milling process proceeds correctly in combined milling?
Ensuring that the paste has a uniform consistency.
How does combined milling impact the flavor of chocolate?
It yields a different flavor as sugar picks up many aromas during grinding.
What happens to Form I cocoa butter at approximately 17 °C?
It rapidly changes into Form II
What is the primary reason for the polymorphism of fats?
The ability of fat molecules to fit together in multiple ways
Which fatty acid is present in the highest percentage in cocoa butter?
Oleic acid
What property makes Form IV cocoa butter relatively soft?
Rapid transformation into other forms
What is the distinguishing characteristic of Form V cocoa butter?
Glossy appearance and good resistance to bloom
What is the purpose of chocolate tempering?
To produce a small fraction of homogeneously dispersed, highly stable fat crystals
What are the characteristics of successfully tempered chocolate?
High gloss, resistance to warmth, pleasant aroma, and smooth mouthfeel
What is the main defect that appears during the storage of chocolate?
Fat bloom
Which method of chocolate tempering involves pouring melted chocolate onto a cool surface and then continuously moving it about until it thickens?
Tabling method
What is the primary aim of tempering chocolate?
To ensure cocoa butter crystallizes in the stable form
