Transformation of Food Stuff 1 ( Form 2, Biology )Online version

Quick true/false questions on food processing and preservation.

by YAKILI LMS
1

High-temperature processing cannot inactivate any bacteria.

2

Secondary processing adds value by transforming basic products into more complex items.

3

Temperature-based preservation methods work identically for all microbial species.

4

Filtration as a preservation method refers to removing microorganisms via filtration.

5

Antibiotics have no role in any preservation strategy.

6

Asepsis is the same as sterile processing in all contexts.

7

Secondary processing always reduces the nutritional value of foods.

8

Streptococcus thermophilus works with Lactobacillus in some dairy fermentations.

9

A disadvantage of preservation can be changes in taste or texture.

10

Lactobacillus is involved in lactic fermentation in products like yogurt.

11

Carbonation is a method of preservation that relies on removing carbon dioxide.

12

Acids used in preservation have no antimicrobial properties.

13

Asepsis aims to prevent contamination during handling and processing.

14

Definition of preservation excludes any intention to extend shelf life.

15

Yeast is never used in food fermentation processes.

16

Fermentation cannot contribute to food safety or shelf life.

17

Low temperature preservation eliminates all microorganisms instantly.

18

Oil and spices have no preservative effect in any food system.

19

Filtration applies heat to remove microbes from liquids.

20

Lactic acid bacteria have no role in flavor development during fermentation.

21

Streptococcus species are never found in traditional fermented foods.

22

Preservation means allowing spoilage to occur more slowly over time.

23

Primary processing converts raw agricultural products into basic edible forms.

24

Irradiation preserves food by heating it to extreme temperatures only.

25

Preservation by chemicals is never used in modern food systems.

26

Lactobacillus is primarily used to cause spoilage in dairy products.

27

Low-temperature processing is used to accelerate microbial growth.

28

Acidic preservation is the only method used to preserve fruits.

29

Streptococcus species are not involved in any dairy fermentation.

30

Preservation is the process of delaying spoilage and maintaining quality.

31

All foods can be preserved equally well by drying regardless of moisture content.

32

Antibiotics are commonly used as the sole method of food preservation in households.

33

Nutrient loss and energy costs are common disadvantages of food transformation.

34

Transforming food can improve safety and extend shelf life.

35

Yeast participates in fermentation by producing alcohol and carbon dioxide.

36

Fermentation only produces undesirable flavors and textures.

37

All fermentation is accomplished without any microbial activity.

38

All preservation methods require the use of radiation.

39

Irradiation is identical to cooking food with heat.

40

Asepsis involves deliberately introducing contaminants to food.

41

Low-temperature methods include refrigeration and freezing.

42

Disadvantages of preservation are always negligible and unimportant.

43

Drying always removes all water, leaving food completely dry and inert.

44

Primary processing includes turning raw crops into ready-to-eat packaged meals.

45

Chemical preservatives are illegal and never used in any country.

46

High-temperature methods include pasteurization and sterilization.

47

High temperature preservation includes pasteurization and sterilization.

48

Filtration can remove microorganisms from liquids as a preservation method.

49

Freezing kills all microorganisms instantly.

50

Drying removes water to inhibit microbial growth.
