QUESTION NUMBER 5(b)

CONCERNS REGARDING THE USE OF PALM OIL IN THE FOOD INDUSTRY

• ENVIRONMENTAL AND CLIMATIC IMPACT:

A substantial part of palm oil development happens to be detrimental to the biodiversity and biological and ecosystems in the lands it is produced. Presently, 33% of all warm-blooded creature species in Indonesia are thought to be in danger as an outcome of this unsound expansion that is quickly infringing within their territory. Deforestation for palm oil production likewise contributes to environmental change.

• IMPACT ON WILDLIFE:

Palm oil production builds availability of creatures to poachers and wild life dealers who catch and sell wild life as pets, utilize them for medicinal purposes or execute them for their body parts.

• IMPACT ON HEALTH:

To produce refined oil, crude palm oil and unrefined palm piece oil are prepared through three refining stages, in particular degumming, blanching and deodorizing, the infusion of chemicals is harmful for health of human beings.

QUESTION NUMBER 4(b)

1. Use of Kinins and Kinetins:

These kinds of chemicals show a delay chlorophyll dilapidation of vegetables that are green in colour.

1. GA Treatment:

GA evidently reduces the ripening of tomatoes, guava and banana then has an impact on ripening which is illustrated by decline in the respiratory rate along with the delayed in change of colour.

1. (CIPA and NOA) Auxins:

Pre-harvest foliar implementation of CIPA and NOA reduces the physio-chemical damage of mandarins that are being stored.

1. Development Retardants (MH and CCC):

MH: The impact of MH on the process of ripening is distinct in comparison to various kinds of fruit and may be dependent on the time at which it is applied along with the extent and the amount of chemical that has been absorbed. Mangoes that were dipped inMH displayed delayed ripening.

CCC: lettuce, broccoli heads and Asparagus spare was retarded by dipping the stem bases insolution of CCC.

1. Metabolic Inhibitors:

Cycloheximide and Actimomycin –D:

When Cycloheximideor Actimomycinis applied to fruits beginning to ripe, the ripening process is reduced.

1. Ethylene Oxide:

Mangoes preserved with ethylene oxide take extensive time in the process of ripening.

1. Sodium Dehydro Acetic Acid:

It is believed to cause delay to the ripening process of strawberries with the reduction in respiration rate.

L: Carbon Monoxide:

It is employed to increase storage life of mushrooms by four-fold.

. Ethylene Absorbents:

Banana is covered in film bag which includes KmnO4 (to absorb C2H4). A business-related preparation of this absorbent called “Purafil”.

QUESTION NUMBER 4(a)

It’s a four-phase fruit ripening process, in the Initiation Phase1, the starch degradation is 100%. As time passes, the exogenous ethylene increases and the fruit firmness decreases to around 80% and pectin solubilisation starts. It begins to deteriorate until it enters Phase2. Hers in this phase, the fruit starts its eligibility to be consumed and depolymerization galactose is lost. With the passage of time it reaches its ripening to the fullest. With more passing time, aroma of the fruit is produced and fruit enters its shelf life. Now, in the last phase, the firmness of the fruit is rapidly being lost and it becomes over ripe with the loss of middle lamella.
