THE INFLUENCE OF ORGANOLEPTIC ANALYSIS ON THE DEVELOPMENT OF NOVEL FOODS

Welcome back to the Amerex Blog! In this post we will talk about the influence of organoleptic analysis in the development of a new food. The organoleptic control of a food is established through qualitative assessments of a sample by experts through the senses of sight, smell, taste and touch. This seems to be a very subjective concept, but it is carried out through quantitative and very rigorous methods that ensure high quality results that can be very relevant for the food industry.

The objective of an organoleptic analysis is to determine how consumers will respond to a new product before its launch, in order to have the possibility of improving and changing it in case its quality is not sufficient to make it a successful launch.

Why should food companies be concerned about organoleptic control?

Manufacturers from the food sector are constantly working on the R&D of their products to meet the demands of consumers. These consumers are continuously evolving and requiring new products (different from those existing) and having different needs that are increasingly oriented towards healthy and clean products. However, the latest statistics tell us that not even 25% of the foods developed by these companies succeed in entering the market.

Therefore, they should use organoleptic analysis to predict the success or not of the launch of a new food or beverage on the market. This method enables the use of expert sensory evaluation to understand the consumer’s perception of a product. It also allows to adapt the product to said consumers and to predict its success before the final launch.

Not only R&D but every department of a food manufacturing company (especially manufacturing, marketing and sales) must be aligned to develop and launch products that meet the demands and expectations of their potential consumers.

What stages must a food go through during its formulation to ensure its organoleptic quality?

There are certain stages in the manufacture of a novel food that allow it to achieve ideal consumer acceptance, and thus ensure that its future performance in the market is positive.

A first stage would include everything related to the organoleptic control of the food. Starting with a screening phase of the organoleptic test to be carried out to determine the quality of the food. In this phase we must choose the most appropriate type of analysis for the food depending on the information we want to gather from it. For example, it is not the same to carry out a sensory evaluation of the organoleptic characteristics to find out if a product is liked, as it is to determine the differences between two formulations and to evaluate these differences. Also, a statistical design will have to be prepared to optimise the tests in order to obtain as much information as possible with as few tastings as possible. And last but not least, the panel of tasters should be selected including expert panel evaluators and/or representative consumers.

The second stage is the actual performance of the sensory test, when the tasters evaluate the different organoleptic characteristics of the food: colour, flavour, smell and texture.

A third stage will be the analysis and interpretation of the results, and will end with the fourth stage of validation and redesign of the product to further adapt its organoleptic characteristics and achieve the final food that will be placed on the supermarket.

As a food manufacturer, what can you do to try to ensure a successful launch of your product?

The truth is that launching a product and making it a hit is difficult, and there is no way to predict exactly how a new product will perform in the supermarket. Nevertheless, there are some recommendations to optimise the sensory evaluation of different samples and increase their chances of success.

You can carry out organoleptic pre-testing with different target population groups for the product you are developing. As part of it, you can focus the conditions of the product so that it completely reflect the result of the analysis that has been carried out.

Other factors such as taking extreme care of the quality of all ingredients that are part of the final food, ensuring good practices and being transparent in the information of these ingredients through labelling and product display help in making the product a hit and not a miss.

Finally, to keep assessing end-customer acceptance through different tools such as satisfaction surveys or other market research.

How can Amerex help you improve the organoleptic qualities of your product?

As we have said before, it should not be forgotten that today’s food and beverage consumers are becoming more demanding and expect certain characteristics in their food that were not so much taken into account until the last few years, such as natural ingredients and additive-free labels.

At Amerex, we manufacture preservation solutions that also help to improve the organoleptic properties of foodstuffs. Not only through starter cultures and their enzymatic activities that give good colour, flavour and aroma in the sausage. Also with our wide range of natural ingredients BIAMEX and SAFEMIX that help to maintain the organoleptic condition of the food during its shelf-life.

Is it possible to create a more homemade product without the use of additives or treatments?

Our company can also help you in the reduction of artificial additives and treatments to obtain a more natural and homemade organoleptic in your final product. For example, in ready-to-eat meals that attempt to imitate the most traditional dishes by removing acidifiers that lower pH and change viscosity and colour. You can see an example here.

FOOD ADDITIVES: ORIGIN, CLASSIFICATION AND ALTERNATIVES

Welcome to Amerex’ Blog! As mentioned in previous posts, it is very common for today’s consumers to take a deeper look at the ingredients shown in food labels. In this blog post we will take a look at the origin, classification and alternatives to food additives to be able to make a conscious decision when buying food on a daily basis.

What are food additives?

The definition of food additives is laid down in Regulation 1333/2008 of the European Parliament and reads as follows: “any substance not normally consumed as a food in itself and not normally used as a characteristic ingredient of food, whether or not it has nutritive value, the intentional addition of which to food for a technological purpose in the manufacture, processing, preparation, treatment, packaging, transport or storage of such food results, or may be reasonably expected to result, in it or its by-products becoming directly or indirectly a component of such foods”.

Essentially, food preservatives are used in the food industry to improve the organoleptic characteristics of foods, increase their shelf-life or facilitate their manufacture.

Are food additives regulated under the law?

The European Food Safety Authority, better known by its acronym EFSA, is the body in charge of evaluating the safety of food additives, either new additives or new uses of existing additives, as well as the re-evaluation of already authorised additives. It states the following data:

  • Identity and characterisation of the additive
  • Stability in food
  • Justification of its necessity
  • Existing authorisations
  • Evaluation of human dietary exposure to the additive
  • Biological and toxicological characteristics

In the framework of its safety evaluations of food additives, EFSA tries to determine the safe levels and the Acceptable Daily Intake (ADI) for each substance. All this information is supported not only by EFSA but also by the Scientific Committee on Food (SCF). This ensures that food additives included in the EU list are considered safe and their limits are correctly identified.Regulation (EC) Nº 1333/2008 and its annexes constitute the legislation under which definitions, the use of food additives and all matters relevant to such additives are regulated.

How are food additives classified?

Additives used in food can be classified according to different criteria such as the origin of the product or, more commonly, according to their functionality. Let’s have a look at these classifications.

Classification according to the origin of the product

A first category would be natural additives, which are those obtained from natural elements through physical methods that do not involve the addition of any other non-natural substance. Examples of natural preservatives are plant-based pectin or agar obtained from algae.

The second category are the synthetic or non-natural additives, which are obtained through the synthesis of products that are not present in nature and/or through processes that generate or include non-natural substances. This category includes most of the preservatives commonly used in the food industry, such as sodium nitrite or citric/acetic acids.

Classification by functionality

Regardless of the natural or synthetic origin of food additives, they can be classified according to their function in the final food. The following is a classification of the most commonly used additives:

  • Colouring agents used to intensify or change the colour of the food and make it more attractive for consumption.
  • Preservatives that are added to extend the shelf-life of the food by protecting against microbiological or enzymatic spoilage.
  • Antioxidants used to also extend shelf-life through mechanisms that prevent or delay oxidation and rancidity caused by physical processes such as exposure to light or oxygen.
  • Emulsifiers that allow the mixture of two or more ingredients that are non-miscible and keep it stable.
  • Thickeners to improve, increase or concentrate the viscosity of a food to ensure an optimal texture for consumption.
  • Flavour enhancers that increase the intensity or durability of the natural flavour of the food.

Other categories of food additives would be e.g. sweeteners, humectants, acidity regulators or flavourings.

What does it mean if an additive is labelled as an E-number in a food?

When us consumers check a label in search of all the ingredients of a foodstuff, we very often find that many of them are labelled as an E number, which is basically an international identification system created for better understanding by consumers.

This E-number system indicates that the food additives listed on the label are approved by the European Union for use in food. In addition, they follow special numbering codes that indicate their classification by functionality as well as the specific substance used. Some examples of how the codes relate to these additives are as follows (they are classified in the hundreds):

  • Antioxidants and acidity regulators: E-300
  • Colouring agents: E-100
  • Preservatives: E-200
  • Stabilisers: E-400
  • Flavour enhancers: E-600

Is it safe to use additives in food?

Historically and for ages, society has been aware of the need to find solutions for food preservation, and therefore salt and vinegar, for example, are traditional preservation methods that many manufacturers still take into account today. Likewise, the use of spices and plants, which are traditional solutions to improve the flavour, aroma and appearance of food. Nowadays, and with the technology being much more advanced, the aforementioned preservatives meet this need, and consumers now place great value on the fact that the use of additives in the food industry must always be safe, justified, transparent and beneficial in its intended purpose.

There are some concerns about the use of some of these ingredients in certain foods and many consumers are more cautious about controlling their dietary intake. For example, one claim is that colouring agents are not safe, as many people develop sensitivity to specific colouring agents such as E-102 or Tartrazine that is mostly used in drinks, sweets and ice cream. Or the cases of infantile hyperactivity developed by some preservatives and their mixtures, equally supported and denied by the scientific community.

The truth is that the additives are regulated by the European Community and have their corresponding authorisation for use, so they meet the requirements established by law. However, this does not mean that all the food additives currently in use should not be monitored and that their functionalities and their suitability for human consumption should not be continuously re-evaluated. It definitely should be.

Are there alternatives to the use of additives in the food industry?

Indeed there are alternatives to food additives. In fact, in the food industry the concern for a clean label and the use of fewer additives and ingredients is becoming more and more relevant, as we mentioned in our previous blog post.

The “chemophobia” or fear of excessive chemicals in processed foods is causing numerous products claiming to be 100% E-number free, and offer more natural alternatives. Therefore, natural preservative alternatives are becoming increasingly popular and are without a doubt the focus of many ingredient manufacturers who want to follow these consumer trends.

Where can I get a natural preservative as an alternative to the use of food additives?

At Amerex we design and manufacture E-number free microbiological blends as alternatives to improve the safety and shelf-life of a wide range of products. Some examples of natural preservatives are our Biamex and Safemix ranges, which can achieve a reduction or even removal of these additives (sorbate, nitrites, sulphites, lactate, acetate…).

More specifically, our nitrite replace solution, BIAMEX-NC, is one of the top products of recent years. Or the AMEXOL range as natural antioxidant alternative to replace acids such as citric (E-330) and ascorbic (E-300).

If you like to know more about the use of these alternatives and many others that we have in our product portfolio, we will be happy to offer you expert advice on food preservation.

THE ORGANOLEPTIC QUALITY OF FOOD

The improvement of the organoleptic characteristics of food can be achieved through the use of additives but also with the use of natural ingredients. In this blog post we will find out how this can be done, which tests the food industry uses to upgrade their products, and which examples of natural ingredients help to improve the organoleptic quality of food.

What are the general properties of food?

Consumers value four groups of food characteristics for their consumption:

  • Sensory or organoleptic characteristics – Colour, taste and smell of the food
  • Physical characteristics – Texture
  • Nutritional characteristics
  • Temporal characteristics – Shelf-life of the food

What are the organoleptic characteristics of food?

The four main organoleptic characteristics of food are colour, taste, smell and texture. These are characteristics that we perceive through our senses and which are decisive in the first impression of the food that we are going to eat. It is therefore very important to take them into account.

Colour

Colour is key in the consumer’s perception of food. It is the first thing we see and it tells us what chemical reactions have taken place during the shelf-life of the food, from manufacturing to consumption. Colour changes in food can show up due to the exposure to light or air, both catalysts in the biochemical reaction that create peroxides responsible for food oxidations. This oxidation results in colour changes from fresh to spoil.

Colour measurement is an effective thermometer in many cases to determine this type of deterioration.  Techniques such as spectrophotometry or technologies such as Minolta are used to evaluate colour changes and use well-defined scales to compare the colour of both liquid and solid foods.

Taste

Five types of flavours are identified in the food industry: salty, sweet, bitter, sour and umami. It is also possible to distinguish between slow tastes and immediate tastes.

In general, all substances have a single taste that is made up of several different flavours.

Smell

Odour is defined by the different volatile substances that are present in food that either come from the food itself naturally, or are the result of adding flavouring ingredients into the food.

When a food is spoiled, it is easy to detect it by the smell.

Texture

Texture is definitely another factor to be taken into consideration, since we use our sense of touch to evaluate food’s condition and choose the one that best suits our own preferences. Some parameters for evaluation are hardness, thickness, viscosity or rigidity. The consumer knows how to detect when any of these parameters becomes unpleasant and that is automatically related to a microbiological alteration that results in us avoiding its consumption.

What additives and ingredients does the industry use to boost the organoleptic quality of food?

Substances used by the food industry to boost the organoleptic quality of food can be divided into two groups: artificial additives and natural ingredients.

Ingredients such as spices, in the same way as salt for preservation or vinegar to extend the shelf-life of food, have properties that improve the organoleptic quality of food.

For example rosemary extract, which not only ensures the flavour and colour of food but also provides aroma and works as an antioxidant. Others such as basil, parsley, oregano or dill enhance flavours, while saffron, turmeric or curry modify the colour while providing food a special aroma and flavour. Other spices provide even more intense flavours, such as pepper or chilli that give a spicy vibe to our food. Many fruits and vegetables also improve the organoleptic characteristics of food thanks to their high pigmentation. Beetroot or blueberries provide more intense tones, while bananas, dates or figs substitute sugars for sweetness.

How to analyse the organoleptic qualities of food in order to know its quality?

We can determine the organoleptic quality of foods by means of many tests to get an idea of their characteristics. One of the most decisive factors in testing is perception, which is evaluated by thresholds. A threshold is the value at which the effects of a stimulus become perceptible to the senses. This threshold is made from the active ingredients in the food within the organoleptic scope. There are several thresholds of perception:

  • The detection threshold, the minimum amount of an odorant to be detected.
  • The recognition threshold is the level of a stimulus needed not only to be detected but also recognized.
  • The differential threshold is the magnitude of change in the stimulus necessary to generate an alteration that is perceptible.
  • The terminal threshold is the maximum value of a stimulus above which an increase in intensity is not perceived.

Perception is the response to organoleptic characteristics. It is therefore a true reflection of food quality that the food industry uses to evaluate consumers. The trend analysis for this evaluation are carried out by quality technicians with different backgrounds such as nutritionists, chemists and engineers. In order to determine the organoleptic quality of a foodstuff, the so-called organoleptic analysis or tasting panels are also carried out. These are qualitative expert assessments based on the evaluation of a sample through the senses. The senses involved in organoleptic analysis are sight, smell, taste and touch, and this analysis is subjective in any case.

How to improve the organoleptic characteristics of food by using natural ingredients?

At Amerex we are always committed to natural ingredients as preservative solutions, which not only help to improve the shelf-life of foodstuffs but also their organoleptic properties.

We have a wide range of ripening starters that through enzymatic activities of microorganisms are able to generate a good colour, flavour and aroma in the sausage. In addition, preservative solutions that maintain the organoleptic condition of the food during its shelf-life. Or even solutions based on yeast technology to provide specific and traditional organoleptic characteristics to the final product.

Replacing chemical additives with natural ingredients is possible, and it also means an upgrade in those products that consumers are increasingly demanding. The clean label philosophy is here to stay, and many manufacturers are committed to meeting the needs of a more demanding end customer.
