Food colouring - what's all the hype about?
« on: January 31, 2022, 06:24:14 AM »
Why is colour added to food?
Colouring is added to foods for a number of different reasons. It can be added to food to:

Make it more appealing

Bring back the natural colours that may have been lost during food processing

Enhance the natural colours or to make the colour’s more ‘even’

Support the taste and enhancing the flavour perception of a food

Stimulate appetite



What is the difference between natural and synthetic colours?
Food colouring with natural substances has been used since approximately 1500 B.C. Natural food colours (dyes) are generally made from the colours found in plants and minerals. Some common natural sources of food colouring include, lycopene (which gives tomatoes their red colour), anthocyanins (which gives berries their purple colour), turmeric (yellow/gold), carotenoids (the yellow in carrots and pumpkin) and betanin (the red found in beetroot).

In the 1800s, synthetic dyes emerged which were made from petroleum or coal. This sparked the regulation of synthetic food colourings across many countries in the world, to ensure they were safe to use. Over the years, some food colours have been linked to health implications and they have since been banned for use within the New Zealand market. Synthetic (artificial) colours are often cheaper and more stable than their natural dye counterparts.

What are the safe levels of artificial colours?

All food additives, including food colours, must be assessed for safety by Food Standards Australia New Zealand before they are permitted to be added to our food. Safe levels are determined by calculating the “acceptable daily intake” (ADI). The ADI tells us how much of a specific food additive we can safely eat each day, throughout our life. The ADIs for synthetic colours has been set well below the level that could cause any adverse health effects. For artificial colours, the ADI is 40mg for each kilogram of body weight. Studies have found the average child in New Zealand eats less than 5% of the ADIs for synthetic colours. To exceed the ADI, a 70kg person would need to consume over 4 litres of soft drinks, or over a kilogram of sweets every day.

A lot of people think that food coloring is totally unnecessary. Maybe it is, but there are lots of people who would choose to buy food with a fun and appealing color. This can be done by using natural ingredients. For example, beet and carrot powders, turmeric, cabbage rose petals, purple cabbage, and dried red fruit powders. These are just a few of the many natural food coloring alternatives. Common sense is important here. To obtain more delicious and nutritious foods.

Verification is needed as part of any HACCP based totally food protection program or gadget. Principle 6 of HACCP requires that the meals business establishes methods for verification. The frequency must be sufficient to aid that the HACCP machine is efficiently running. 먹튀컷 The meals business need to be able to reveal to outside food safety auditors that their HACCP machine and food protection software has been implemented and it is powerful.

Ultimately, there’s a bouquet of methods to pick out from, that aid the qualitative method inside meals distribution. A attempted and examined approach is to installation a label verification device, as a delegated step along the meals deliver direction. These inspection systems are especially important when handling perishables and packaging, in which in-depth scrutiny of the end product is obligatory, at every step of the production technique.
