新しい食品の一般的な質問
「新しい食品」とは何を意味するのでしょうか？
Broadly speaking, new foods (which are sometimes also called novel foods) are exactly that: ingredients and products that have not previously been consumed as foods or beverages. The term can also apply to existing dishes and ingredients that are produced through innovative new processes or technologies, as well as food items that have an established history in one part of the world but are considered “new” somewhere else.
From a regulatory standpoint, the legal definition of what constitutes a “new” or “novel” food will vary from region to region. Most new food legislation focuses on ingredients, process or technologies that do not have an established history of safe use in food production in that particular jurisdiction. For businesses, manufacturers and retailers working in this space, it is important to know exactly what applies from your local authorities, as this can impact approval for introducing new products on the market.

新しい食料製造の開発を推進しているのは何でしょうか？
Several interconnected socio-political, environmental and market factors. These include the need for:
- sustainable food systems, a less resource-intensive supply chain and alternatives to animal-based ingredients in order to reduce environmental impact
- food safety – as there is no animal contact in new fermentation processes, risks of zoonosis and contamination from animals are heavily reduced
- enough food to support a growing population
- alternatives to animal-based ingredients in order to meet consumer demand.
持続可能な食品システムとは何でしょうか？
According to the Food and Agriculture Organization of the United Nations (FAO), a sustainable food system is one that is:
- economically sustainable: the enterprise is profitable for all stakeholders across every part of the value chain
- socially sustainable: the food produced offers benefits for society broadly, such as food security that ensures healthy and nutritious diets for everyone
- environmentally sustainable: production and consumption of the food has a positive or neutral impact on the planet and our natural resources4.
代替タンパク質とは何でしょうか？
Being macronutrients we need to survive, proteins are an essential part of the human diet. In addition to nutritional benefits, there are functional proteins that support solubility, emulsification, gelation and foaming, water binding and heat stability. Functional proteins – more specifically, some enzymes – can also catalyse specific chemical reactions to give food items certain desired flavours or textural properties.
Today, our food systems are heavily reliant on animal-based protein sources like meat, fish, eggs and dairy. The term “alternative proteins” generally means alternatives to these sources in particular. There is a great deal of development in the new food space today devoted to finding additional sources to proteins that fulfil key nutritional and functional roles in food and beverage production.
There are many different potential sources for alternative proteins, but innovation in this area can generally be organized into four main categories:

「高タンパク質」とはどういう意味でしょうか？
Protein makes up for approximately 20% of an average human body, and we get protein from our diet. When it comes to protein content in food, the EU and the UK regulations allow two official claims:
- “High protein” indicates that the product contains at least 20% protein
- “A source of protein” indicates that the protein content is between 12 and 20%
新しい食品製造における植物由来の材料はどのような役割を担っているのでしょうか？
Once thought of just in terms of “vegetarian” or “vegan”, today the broader label of “plant-based” is typically used for food and beverage products where the key ingredients come from plants. Such ingredients can include vegetable and fruit ingredients as well as grains, seeds, legumes and more.
Plant-based ingredients have been important to developing new food products over the last several years. Today there is an ever-growing category of alternative foods and beverages that rely primarily or exclusively on plant-based ingredients produced through innovative new processes.

新しい食品製造における発酵は役割どのようなものでしょうか？
Microbial fermentation processes have been used to produce, enhance and preserve foods and beverages for thousands of years. It is the key behind everything from bread and beer, to cheese and yoghurt, to pickles and kimchi – and much more.
When we talk about fermentation in the context of new foods, however, we’re talking about a category of processes that have only begun being used in food production much more recently. In particular, there are two main types of processes that have become the focus of development in the new food space:
When we talk about fermentation in the context of new foods, however, we’re talking about a category of processes that have only begun being used in food production much more recently. In particular, there are two main types of processes that have become the focus of development in the new food space:
- Biomass fermentation, in which vast quantities of unicellular microorganisms are “grown” and “harvested” to either be used as ingredients in food production, or formulated for end-use.
- Precision fermentation, in which microorganisms are utilised as a means of producing proteins, fats, vitamins or other compounds that can serve as functional ingredients in food production.
培養肉とは何でしょうか？
Cultivated meat, also known as cultured meat or cellular lab-grown meat, refers to meat that is grown directly from cells. In this process, cells are used to build muscle tissue and fat in a biological process that is the same as what happens inside of an animal.
Meat cultivation thereby allows for the production of bio-identical “real” meat products, but without the use of live animals and the resource consumption that animal husbandry requires. In theory, the production of cultivated meat could therefore provide an efficient way of producing highly desirable new food products and ingredients in the years to come.

細胞農業とは何でしょうか？
Cellular agriculture is a term that is sometimes used to refer to a category of processes where cell cultures are involved in the production of new food ingredients. This can include both meat cultivation and fermentation processes.
バイオマス発酵
バイオマス発酵とは何でしょうか？
Biomass fermentation, which is generally also called “single-cell production,” (although some producing microbes may be multicellular) harnesses fermentation to produce high quantities of a specific microorganism. During fermentation, the microorganism grows and multiplies, resulting in a large collection of microorganisms known as a microbial biomass. This biomass can then be “harvested”, separated from broth, purified and used as either an ingredient in food and beverage production or formulated for direct end-use.
In other words: the microorganisms that reproduce through the biomass fermentation process are themselves ingredients. And they can reproduce very quickly – in some cases, doubling the size of the biomass in hours, compared to months or years for animals. Common microorganisms used in these processes include microfungi, yeast or microalgae.

バイオマス発酵と精密発酵の違いは何でしょうか？
In biomass fermentation, the microorganisms that grow and reproduce are themselves ingredients.
In precision fermentation, the microorganisms themselves are not used as ingredients. Instead, they are “programmed” to produce certain proteins, fats, vitamins or other compounds which can be harvested for use as functional ingredients.

バイオマス発酵は「新しい食品」プロセスと見なされるでしょうか？
Biomass fermentation itself is not new to commercial food processing. In fact, there are examples of biomass fermentation processes used in the production ingredients since the early twentieth century. Even the production of microfungal biomass proteins, now a common application area, dates back at least to the 1970s, when it was first used for animal feed5.
At the same time, biomass fermentation processes are currently being used to produce innovative foods and ingredients that can very much be described as “new foods.” Developers in this space are continuously exploring new microorganism strains and new applications that can be used to introduce new products. Today, much of the focus is on creating new types of alternatives to traditional meat and fish products.

バイオマス発酵はどのような種類の食品用途に関係しているのでしょうか？
Today, biomass fermentation is increasingly used in the development of alternative foods and ingredients that can replicate characteristics of conventional, animal-based food products. A key application area is the development of meat and fish substitute products (meat analogues). Protein-rich strains of microfungi have often been used for this application, as they can provide a texture and mouthfeel similar to traditional meat and fish products. Production of meat and fish substitutes using yeast and microalgae is also a growing area of development.
「ハイブリッド」な新しい食品とは何でしょうか？
Biomass fermentation can also be used in the development of so-called “hybrid” new food products. In these cases, ingredients produced through biomass fermentation are combined with plant-based or cultivated meat ingredients. By using different ingredients that offer different characteristics, the intended result is typically to better reproduce the flavour, textural or nutritional profiles of particular animal-based food products.
現在のバイオマス発酵の市場はどのような状態なのでしょうか？
According to the non-profit Good Food Institute, there were at least 136 active companies “focused primarily on fermentation for alternative proteins” as of 2022. 74 of these companies focus on biomass fermentation, and the majority of those specialise in producing analogues to various meat and seafood products1.
バイオマス発酵で作られた材料はヴィーガンでしょうか？
Yes. As these ingredients are never derived from animals, they are considered vegan.
商業用バイオマス発酵にはどのような種類の装置が使用されるのでしょうか？
Most fermentation processes involve a fermenter or bioreactor. In precision and biomass fermentation a bioreactor is needed to provide a controlled environment for the microorganisms and induce the production of the target ingredients. Additional equipment is needed upstream of the fermenter to prepare the microorganism and the feed it needs for fermentation. For example, powder handling, heat treatment and high shear mixing are essential technologies to prepare the media for the fermentation process. A seed train is a sequence of special equipment to produce certain amount of biomass which is introduced to the broth media of the reactor to start the process. There are also equipment needs downstream of the fermenter to further process (concentrate, separate, formulate etc) the biomass for the intended ingredient or product.
There is a huge range of processing equipment and technologies to be considered, and selecting the right solutions will depend on the nature of the microorganism in question and the type of product being produced. This is an area where businesses can draw on extensive knowledge from the food industry broadly. Working with partners that have broad experience of commercial food and beverage production can therefore be a good idea when setting up the solution.

精密発酵
精密発酵とは何でしょうか？
In precision fermentation, microorganisms are “programmed” to reproduce certain target proteins or other compounds that can be “harvested” for use as functional ingredients for new food and beverage products.
The target ingredients in question can be proteins, fats or sugars found in traditional, animal-based ingredients, which impart certain taste, textural or nutritional characteristics. In other words, precision fermentation makes it possible to produce vital ingredients from eggs, dairy or meat – without any need for live animals.

精密発酵は「新しい食品」プロセスと見なされるでしょうか？
Precision fermentation has a history stretching back several decades. It is a well-understood and used process in pharmaceutical manufacturing.
In food production, precision fermentation has traditionally been used for producing enzymes. Examples include enzymes used in juice extraction, as well as the production of non-animal rennet used for making cheese.
However, it is only recently that precision fermentation has been explored as a means of creating alternative proteins, fats and sugars traditionally found in animal-based sources. As this is a new – and still developing – application area, products such as dairy or egg proteins produced in this fashion are generally classified as “new foods.”

According to the non-profit Good Food Institute, there were at least 136 active companies “focused primarily on fermentation for alternative proteins” as of 20221. The majority of these companies focus on biomass fermentation, but the number of precision fermentation-based companies is growing quickly. There were at least 62 active precision fermentation companies as of 2022, and the primary focus is products using non-animal fats or proteins from dairy3. However, regulatory issues – which are present in most geographies – mean that many precision fermentation companies face hurdles in getting products approved for commercial food production.
精密発酵は食肉培養とどのように違うのでしょうか？
In precision fermentation, specific proteins, fats, vitamins or other compounds with functional properties are reproduced by microorganisms and then harvested to be used as a functional ingredient in further food and beverage processing.
In meat cultivation, the meat is produced by cultivating animal cells directly7., but microorganisms are not involved. Here, the cells provide the basic elements needed to build muscle tissue and fat.

精密発酵には遺伝子組み換え作物が含まれているのでしょうか?
Genetic engineering is an inherent part of the precision fermentation process, as it starts with identifying a target gene and encoding this into the DNA of a bacteria or other microorganism. The result of the gene encoding is what is known as a genetically modified microorganism (GMM), which in many geographies is subject to similar regulatory oversight as other genetically modified organisms (GMOs) used in the food and beverage industry. However, the end-goal of most precision fermentation processes is to produce an ingredient that is not, itself, genetically modified.
精密発酵で作られた材料はヴィーガンでしょうか？
Precision fermentation is capable of producing many different ingredients, including animal-like recombinant proteins and other nutrients from meat, milk and eggs. Here, this happens without the involvement of animals. Hence, precision fermentation products are often labelled “animal-free”.
However, as per the definition from vegan.org6., a vegan product must not
In other words: whether a specific precision fermentation-derived ingredient meets the vegan criteria depends on the interpretation of the manufacturer, the consumers and the relevant local regulatory bodies.

Many of the technologies that can be considered for commercial ingredient production with precision fermentation were originally developed for other types of food and beverage manufacturing. For businesses in this space preparing to make the leap from lab and pilot-scale production, there may be a lot of questions about how to best select the right equipment. A partner with broad knowledge of food and beverage processing can support with technological solutions that make precision fermentation processes viable at commercial scale.
