Q1. _________ Is Not Free To Act As A Solvent For Salts Or Sugars.

A. Bound Water
B. Free Water
C. Entrapped Water
D. All Of The Above

ANSWER: A. Bound Water

  • Explanation: Bound Water Is Not Free To Act As A Solvent For Salts Or Sugars. Bound Water Is Defined As Water That Cannot Be Easily Withdrawn. Different Methods Of Measurement Yield Different Bound Water Values In A Given Food. Many Food Ingredients Can Bind Or Hold Onto Water Molecules, Making Them Difficult To Release And Causing Them To Behave Differently Than Liquid Water. It Is Not Free To Operate As A Salt Or Sugar Solvent.


Q2. ________ Is A Type Of Wastewater Treatment Method That Is Particularly Designed To Purify Industrial Wastewater For Its Reuse And Release Safe Water To The Environment From The Harmful Effect Caused By The Effluent.

A. Sewage Treatment Plant
B. Effluent Treatment Plant(ETP)
C. Chemical Oxygen Demand
D. Biological Oxygen Demand

ANSWER: B. Effluent Treatment Plant

  • Explanation: Depending On The Industry, Industrial Effluents Contain A Variety Of Elements. Oils And Grease Are Present In Some Effluents, And Harmful Compounds Are Present In Others (E.G., Cyanide). Degradable Organic Contaminants Can Be Found In Food And Beverage Factory Effluents. Because Industrial Wastewater Contains A Wide Range Of Contaminants, A Treatment Method Known As ETP Is Required.


Q3. ___________ Is A Treatment Pond Provided With Artificial Aeration To Promote The Biological Oxidation Of Wastewater.

A. Activated Sludge Process
B. Aerated Lagoons
C. Filtration
D. Flocculation

ANSWER – B. Aerated Lagoons

  • Explanation – Aerated Lagoons Are Deep Waste Stabilization Ponds Where Sewage Is Aerated With Mechanical Aerators To Stabilize The Organic Matter In The Sewage Rather Than Depending Solely On Photosynthetic Oxygen Provided By Algae. One Of The Most Efficient, Cost-Effective, And Low-Maintenance Wastewater Treatment Systems Is An Aerated Lagoon.


Q4. ________ Are Food Packaging Additives Usually Added To PVC For Softening, And They Are Also Known As Plasticizers.

B. Propylene Glycol
C. Phthalates
D. Antistats

ANSWER – C. Phthalates

  • Explanation – Phthalates Are Softening Chemicals That Are Commonly Used In PVC. They Are Also Known As Plasticizers. Catalysts Based On Phthalates Are Also Utilized To Make Polypropylene Polymers. Phthalates Have Been Related To Lower Fertility, Reproductive Toxicity, And Testicular Toxicity In Animal Studies; Hence, They Are A Source Of Worry. Food Is Thought To Be The Source Of Some Phthalates


Q5. _______ Is An Aerobic Treatment System That Utilizes Microorganisms Attached To A Medium To Remove Organic Matter From Wastewater.

A. Sedimentation
B. Grit Chamber
C. Coagulation
D. Trickling Filters (TFs)

ANSWER – D. Trickling Filters (TFs)

  • Explanation- To Remove Organic Materials From Wastewater, Trickling Filters (TFs) Are Utilized. The TF Is An Aerobic Treatment System That Removes Organic Materials From Wastewater Using Microorganisms Attached To A Medium. A Variety Of Technologies, Such As Rotating Biological Contactors And Packed Bed Reactors, Use This Type Of Technology (Bio Towers). Attached-Growth Processes Are The Name For These Systems.
