Over the past 40 years, consumption of cashews and other nuts in the U.S. has markedly increased, due to their nutritional properties and perceived health benefits.1,2 Plant-based dairy food alternatives are also increasing in popularity and are capturing a small but robust part of the global food market. In the U.S., retail sales of plant-based milk and dairy alternatives totaled $2.6 and $2.1 billion dollars, respectively, in 2021. Annual retail sales of plant-based cheese alternatives increased 85 percent from 2018 to 2021.3 This increase in popularity has led to a variety of plant-based alternative foods being available to consumers, including those made from almonds, soy, coconut, oats, and emerging products made of lupine and cashews.4,5 Currently, the U.S. has not established compositional requirements for any nut-based milk alternatives or nut-based cheese alternatives. However, in February 2023, FDA published a draft guidance on the labeling of plant-based milk alternatives and the use of voluntary nutrient statements.6
Nut-based milk alternatives are generally made from liquid-based extracts of plant materials. In addition to water and plant extracts, products may contain other ingredients such as sweeteners, salt, oils, functional ingredients, flavorings, and vitamin and mineral fortifications.7 The fluid obtained from the breakdown of nuts soaked in water and homogenized is similar to the appearance of cow's milk.5,8 Nut-based cheese alternatives are also products made from the liquid extracts of nuts with the addition of other ingredients. They are shaped and may be processed similarly to dairy milk-based cheese, such as by fermentation.9
