1.1 UNDERSTANDING FOOD SCIENCE

➢ The application of scientific principles to create and maintain a wholesome

food supply.

➢The study of the physical, biological, and chemical changes in food.

(Naturally or intentionally induced).

➢ Food science also includes understanding the nutritive value and the

means (methods) to make food and drinks last longer, safe, nutritious and

palatable.

1.1 UNDERSTANDING FOOD SCIENCE –THE COMMON TERM (FOOD LANGUAGE)

➢ The application of scientific principles to create and maintain a wholesome

food supply.

➢The study of the physical, biological, and chemical changes in food.

(Naturally or intentionally induced).

➢ Food science also includes understanding the nutritive value and the

means (methods) to make food and drinks last longer, safe, nutritious and

palatable.

Page 13: Introduction to food science & technology

1.1 UNDERSTANDING FOOD SCIENCE –THE COMMON TERM (FOOD LANGUAGE)

FOOD

• anything solid or liquid which when swallowed, digested and assimilated, nourishes the body.

NUTRIENT

• specific substances in food that are used by the body for proper growth, development and maintenance of good health.

NUTRITION

• The process where our body utilizes the nutrient obtained from food for health and growth.

Page 14: Introduction to food science & technology

1.1 UNDERSTANDING FOOD SCIENCE –THE COMMON TERM (FOOD LANGUAGE)

FOOD FORTIFICATION

• The deliberate addition of specific micronutrients to processed foods. Fortification can be used to replace nutrients lost during food processing or correcting a dietary deficiency in a population/community

FUNCTIONAL FOOD

• A food or food component to which an existing ingredient or a new ingredient has been added to provide additional benefits, usually disease prevention or improved health.

GENETICALLY MODIFIED FOOD

• The use of biotechnology to alter the genes of a animal or plant in order to improve the characteristics of that animal or plant, for example, increased yield, increased nutritive value, increased insect resistance.

Functional food – healthy gutFunctional food – healthy heart

1.1 UNDERSTANDING FOOD SCIENCE –THE COMMON TERM (FOOD LANGUAGE)

FERMENTATION

• The anaerobic conversion of sugar to carbon dioxide and alcohol by yeast. The properties of moleculesare altered producing a desired product with a different flavour, easier digestion and increased nutrition and shelf life.

MICROBIAL SPOILAGE

• Deterioration of the sensory, physical or chemical properties of food due to exposure to conditions that result in the production of moulds, yeasts or bacteria.

PRESERVATION

• The processing of food to eliminate or control conditions that cause spoilage.

Page 17: Introduction to food science & technology

1.1 UNDERSTANDING FOOD SCIENCE –THE COMMON TERM (FOOD LANGUAGE)

FOOD SUPPLY CHAIN

• Interdependent steps and operations that bring food from farm to our kitchen.

FOOD SECURITY

• All people at all times have access to sufficient, safe, nutritious food to maintain healthy & active life. (Availability & having access to food)

SUSTAINABILITY

• Producing, manufacturing and transporting food in a way that maintains an ecological balance to ensure sufficient healthy food is available for future generations. (Protectthe diversity of nature, and avoid damage to natural resources).

MORE FOOD SCIENTISTS: WHY DO WE NEED THEM?

• How can food companies develop new products

linked to optimal nutrition?

• who is advising Government about food

security and the role that the Malaysia will have

to play in the future security and sustainability

of the world's food supply

Page 27: Introduction to food science & technology

MORE FOOD SCIENTISTS: THE PROCESSED FOOD

• Misconception about “processed food” or “processing food”

– synonymous with ready meals laden with fat and salt.

• The truth is, harvesting, packing, transport and storage of fresh produce is a food process.

• The processed food industry covers many sectors such as:

– Dairy: fresh milk, UHT milk, yoghurts, ice cream

– Baking: sliced bread, bread rolls, cakes, home bake products, biscuits

– Cereals: breakfast cereal products, mueslis, cereal bars

– Snack foods & confectionary: crisps nuts, chocolate and sweets

– Prepared vegetables: washed and cut vegetables, mixed salad leaves

– Canned products

– Frozen foods

– Beverages: tea, coffee, soft drinks

– Fresh produce: vegetables, meat, poultry and fish

Page 28: Introduction to food science & technology

MORE FOOD SCIENTISTS: THE HEALTH• Essential to find the BALANCE between reformulating food products to reduce

levels of salt, saturated fats and trans fats while ensuring their functional roles

within food products are not lost

• For example: Obesity is an increasing problem for society affecting nearly a quarter

of adults and a fifth of children. Tackling this problem will involve food and

nutritional scientists and technologists.

– Research helps in building understanding of how food products impact on

satiety and the physiology of the gut, hopefully allowing the formulation of food

products with reduced potential for contributing to obesity.

Page 29: Introduction to food science & technology

MORE FOOD SCIENTISTS: THE HEALTH• Meanwhile, trans fats has an important role in maintaining an acceptable texture in

food products, but at the same time there’s concerns about the effects of on

coronary heart disease.

– Alternative formulations, which include some increases in saturated fat content

and alternative processing, are needed to achieve the desired texture

• The food industry is also on the track to reduce salt & sugar levels in food

products. Apart from taste, however, both ingredients are important for

preservation (lowering water activity and preventing spoilage).

Page 30: Introduction to food science & technology
Page 31: Introduction to food science & technology

MORE FOOD SCIENTISTS: THE FOOD SECURITY

• Food security is NOT simply

GROWING MORE food.

• Food scientists and technologists

play a key role in converting raw farm

produce into food products ready for

consumption.

• The goal must be to convert as much

produce as possible into good

wholesome products with a minimum of

energy consumption and waste

throughout processing, packaging and

distribution.

Page 32: Introduction to food science & technology

MORE FOOD SCIENTISTS: THE FOODCHOICE

• Producing healthy foods and functional

foods is off little benefit if consumers do

not choose to eat them.

• Understanding how to make a product

palatable to consumers is the job of

sensory analysis (aims to understand how

we taste and smell foods)

Page 33: Introduction to food science & technology

1.3 AN OVERVIEW OF FOOD LAW & REGULATION

• Receiving safe food is the right of every consumer asrecognized by Food & Agriculture Organization (FAO)and World Health Organization (WHO).

• Effective food legislation and control system isfundamental to ensure:

– Food produced/supplied meet the safety standards

– Protect consumers from fraudulent and risks associatedwith unsafe food.

– Fair trade activities

• Malaysia has enacted Food Act 1983 and FoodRegulations 1985 which came into force on 1st Oct1985 to protect the public

– against food related hazards

– against fraud in the preparation, sale and use of food

– to promote and motivate the preparation, handling,distribution, sale and consumption of safe, high quality food

Page 34: Introduction to food science & technology

1.3 AN OVERVIEW OF FOOD LAW & REGULATION -AUTHORITIES

• Ministry of Health (Food Safety and Quality Division, FSQD) is

mainly responsible for the enforcement of the Food Act 1983 and

its subsidiary legislation, the Food Regulations 1985.

• In 2001, National Food Safety and Nutrition Council was created to

act as the highest advisory body to the government on food safety.

– supported by FSQD for food safety aspects and the Nutrition Division for

nutritional aspects.

• The Nutrition Division of MOH also issues guidelines pertaining to

nutrition, such as, the Malaysian Dietary Guidelines 2010 and

Malaysian Dietary Guidelines for Children and Adolescents 2013.
