In an era where sustainability and food security are paramount, the concept of future-proof proteins has gained significant attention. Among the various preservation techniques available, freeze drying has emerged as a highly effective method for producing ‘future-proof proteins’. In this article, we will explore the concept of future-proof proteins, the freeze drying process, the benefits of freeze drying for protein preservation, and how Shepherd Foods can play a pivotal role in this field for your business.

What are Future-Proof Proteins?

Future-proof proteins refer to protein sources that are nutritious, sustainable, and capable of meeting the increasing global demand for food. They are protein sources that address the challenges posed by an expanding global population, dwindling resources, and the need for sustainable food production. 

Examples of future-proof proteins include plant-based proteins, such as legumes and algae, as well as alternative protein sources like insects and cultured meats. These protein sources offer a promising solution to the growing demand for food while minimizing the impact on the environment.

What is Freeze Drying?

Freeze drying, also known as lyophilization, is a preservation technique that involves removing water from a product while retaining its structure and nutritional content. The process consists of three main stages: freezing, primary drying, and secondary drying. First, the product is frozen at low temperatures, typically below -40°C (-40°F), which converts the water content into ice. Then, in the primary drying phase, a vacuum is applied, and the temperature is raised to promote sublimation, where ice directly transitions from a solid to a gas without passing through a liquid state. Finally, in the secondary drying stage, residual moisture is removed by raising the temperature slightly higher.

Why is Freeze Drying Beneficial for Producing Future-Proof Proteins?

Freeze drying offers several benefits that make it an ideal method for producing future-proof proteins:

Preservation of Nutritional Value: One of the key advantages of freeze drying is its ability to retain the nutritional content of proteins. The low temperatures used in the freezing stage minimize damage to heat-sensitive nutrients, ensuring that the proteins remain intact and nutritionally valuable. This makes freeze-dried proteins a viable option for providing essential amino acids and other vital nutrients.

Extended Shelf Life: Freeze-dried proteins have an extended shelf life compared to other preservation methods. The removal of moisture prevents the growth of microorganisms, such as bacteria and molds, which are responsible for spoilage. This extended shelf life allows for storage and distribution over longer periods, reducing food waste and enhancing the availability of future-proof proteins.

Lightweight and Convenient: Freeze-dried proteins have a significantly reduced weight and volume compared to their original form. The removal of water during the freeze drying process results in lightweight and compact products that are easy to transport and store. This convenience makes freeze-dried proteins an excellent option for meeting the nutritional needs of individuals in various settings, including space missions, outdoor activities, and emergency situations.

Rehydration without Compromising Quality: Another advantage of freeze-dried proteins is their ability to rehydrate quickly without compromising quality. When water is reintroduced, the proteins regain their original structure, texture, and taste. This rehydration process allows for easy consumption, whether in the form of reconstituted meals, protein shakes, or snacks.
