Environmental Monitoring & Assessment Flashcards

When panelists must judge true product color, which light source is preferred?

Answer: Daylight-equivalent lighting around 6500 K

Daylight-equivalent (about D65, 6500 K) lighting shows color accurately.

Which material is most suitable for sensory booth countertops?

Answer: Non-porous, odor-free, easy-to-clean laminate or stainless steel

Non-porous, odorless surfaces don't hold onto odors and can be cleaned thoroughly.

What is the main purpose of pass-through hatches between the prep area and the booths?

Answer: To serve samples without assessors seeing preparation or staff

Hatches keep the booth isolated while samples are served blind.

Panelists are commonly told to avoid eating, drinking (other than water), and smoking for how long before a session?

Answer: At least 30 minutes

About 30 minutes lets residual flavors clear without being impractical.

Which instrument is used to check that booth lighting intensity meets specifications?

Answer: Illuminance (lux) meter

A lux meter measures illuminance at the booth work surface.

After a session evaluating highly fragrant air-care products, what is the most important environmental step before the next session?

Answer: Ventilate long enough to clear lingering odors

Enough air exchange stops odor carryover into later evaluations.

What is the main reason for side partitions between individual sensory booths?

Answer: To stop assessors from influencing or talking with each other

Partitions keep judgments independent by blocking visual and verbal contact.
