The Rise of Plant- and Cell-Based Meat & Implications on Food Safety Testing
By the bioMérieux Editors | Reading time: 2 min
Meat is an important source of nutrition for many people worldwide. The global demand for meat has continued to grow over the past 50 years with production more than tripling over time. While the demand for meat has continued to grow, there has also been a substantial increase in the number of people who are adopting dietary alternatives to traditional animal proteins, citing public health, environmental impact, and animal welfare concerns. These alternatives come in the form of plant- and cell-based meat (PBM and CBM) products. As these products become more commonly accepted, it is important to ensure that they are held to the same microbiological standards as animal-based meat (ABM) products to protect consumers.
PBM products usually look like traditional ABM products but are alternatively made from soy, peas, beans, mushrooms, mung beans, or wheat gluten. PBM products are becoming increasingly popular and have reached such a level of commercialization that they are being offered at traditional fast-food chains. The popularity of meatless diets is rising rapidly with the global vegan meat market expected to reach $7.5 billion by 2025.
CBM, or cultured meat, is produced using in vitro cultures of animal cells. In some countries, CBM has not yet been mass commercialized like PBM, but is moving from development into small-scale production. In just five years, the CBM industry has evolved from a handful of startups to around 80 startups. Countries like Singapore have had success with getting regulatory approval from the government. In 2020, the Singapore Food Agency approved Eat Just’s cell-cultured chicken, making the country the first in the world to sell cultured meat to consumers.
Considerations for Food Safety and Quality Testing
As the popularity of PBM increases and CBM products continue to evolve, the need for adapted food safety and quality testing will increase. PBM products have different levels and forms of macronutrients than their animal counterparts, which can influence spoilage rates. Additionally, the variety of ingredients in PBM products, such as yeast extract and spices, can result in different microbial loads. Each ingredient should be considered during the PBM formulation process to reduce the risk of contamination and spoilage. After formulation, comprehensive tests should be conducted on product samples to ensure consumer safety.
The inherent formulation and manufacturing complexities associated with CBMs also create food safety and quality testing challenges. Two major concerns for CBMs are the use of growth hormones and antibiotics in the manufacturing process. Before becoming commercially available, similar standards for production, processing, and testing of ABM should be applied to CBM. Processes for accurate and efficient safety and quality testing for both PBM and CBM are essential as these products become more commercially available and demand increases.
