Clean convenience: are healthy ready meals preferred?

Most consumers care about the ingredients and the technology used to make their microwavable dinners and other ready meals, according to a new study led by Washington State University researchers.

The study found that many consumers were willing to pay a premium for ready‑to‑eat meals with a ‘clean label’ showing few ingredients.

It also found that the technology used to process the ready meals is important to the consumer. The study found that consumers will pay more when they know the processed foods are made with a new technology that helps limit the number of additives and preservatives.

“Our findings emphasise the importance of providing consumers information about a new food technology and the resulting benefits,” said Karina Gallardo, a WSU professor of economics and corresponding author of the study in the journal Agribusiness. “As foods with ‘clean labels’, that is foods with few ingredients, become more popular, these types of technologies will also become more valuable to food manufacturers.”

For the study, Gallardo, fellow WSU economist Jill McCluskey and Kara Grant, an economist at Missouri Western University, conducted a survey and choice experiments to estimate how much consumers value foods with clean labels, which typically include only a handful of ingredients and no additives or preservatives. They surveyed another group of study participants on whether or not a clean label that included the name of a new technology used to make their potential purchase affected their valuation.

“Shelf-ready meals that warrant a clean label have been historically difficult to produce with conventional food preservation technology but recent breakthroughs are making it possible,” McCluskey said. “However, because consumers are often wary of adopting new technologies, especially when it comes to the food they eat, it is important to consider their perception of the costs and benefits.”

The technology the study participants were asked about is called Microwave Assisted Thermal Sterilisation or MATS. Developed by WSU food scientist and Regents Professor Juming Tang, MATS works like a microwave oven, using heat to kill pathogenic bacteria, which is designed to ensure both food safety and preserves the taste, texture and appearance of processed meals.

Overall, 56% of the study respondents who were asked if they preferred foods that bore both a clean label and the name of the new technology exhibited positive reactions.

While both groups of participants exhibited an overall preference for clean labels, there was a large minority of people in the study who weren’t interested in paying the price premium for the product with fewer ingredients. Around 39% of respondents in the survey group that was asked solely about clean labels and not the new technology exhibited a negative reaction. These participants tended to have lower than a $67,000 annual income, have children in the household and perceived themselves to be less healthy.

“This group does not consider the message ‘absence of artificial ingredients’ as important in the labels but does consider a gluten-free label as being important,” Gallardo said. “It really illustrates the fact that the decision of which foods to buy and consume is very complex.”
