🧪 LAB 1 — Coffee Cherry Anatomy & Waste Mapping

📘 Form Title

KCS Lab 1: Coffee Cherry Anatomy & Circular Waste Mapping

Q1. (Multiple Choice – 1 point)

Which part of the coffee cherry is richest in fermentable sugars?

• ☐ Exocarp
• ✅ Mesocarp (Mucilage)
• ☐ Endocarp
• ☐ Silverskin

Q2. (Checkbox – 2 points)

Select ALL coffee by-products generated during wet processing:

• ✅ Coffee pulp
• ✅ Coffee mucilage
• ✅ Parchment
• ☐ Roasted beans
• ☐ Brewed coffee

(Correct if all 3 selected, others not)

Q3. (Short Answer – 2 points)

Why is coffee pulp considered an environmental pollutant if untreated?

Correct keywords (Google Forms → answer feedback):

• High organic load
• Fermentation in water
• Oxygen depletion / contamination

Q4. (Short Answer – 2 points)

From a scientific perspective, why is coffee pulp NOT waste?

Correct answer idea:
Because it contains sugars, fibre, and bioactive compounds that can be converted into energy or value-added products.

Total: 7 points

🧪 LAB 2 — Sugar Content & Fermentation Potential

📘 Form Title

KCS Lab 2: Sugar Measurement & Fermentation Potential

Q1. (Multiple Choice – 1 point)

What does a high °Brix value indicate?

Q2. (Short Answer – 2 points)

Name TWO sugars commonly found in coffee mucilage.

Accepted answers (set as multiple correct):

• Glucose
• Galactose

Q3. (Multiple Choice – 1 point)

Why is coffee mucilage ideal for fermentation?

• ☐ High fat content
• ☐ High mineral content
• ✅ High fermentable sugar content
• ☐ Low moisture content

Q4. (Short Answer – 2 points)

During fermentation, why does °Brix decrease?

Correct concept:
Sugars are being consumed by microorganisms.

Total: 6 points
