Introduction

U.S. retail sales of cat and dog food hit $50 billion in 2021 – an increase of 15% from 2020 – and the growth is driven by consumer demand for premium, expanded fresh/raw category, human-grade, and science-based formulations. The UNL Food Processing Center is pleased to offer a workshop to pet food manufacturers and entrepreneurs interested in learning more about high pressure processing (HPP) and freeze drying technologies to produce high quality, safe raw pet foods and treats. 

The introductory and hands-on workshop provides participants an opportunity to interact with industry experts and university researchers and learn more about HPP, freeze drying, water activity, product shelf-life, food safety regulations, market trends and best practices. The workshop combines lectures and pilot plant demonstrations. There will also be an opportunity to visit HPP and freeze drying co-manufacturing facilities near Lincoln, Nebraska.

How are high pressure processing, freeze drying and water activity used in manufacturing high quality, safe raw pet foods and treats?

hpp

High-Pressure Processing (HPP) is a cold pasteurization technique by which products, already sealed in its final package, are introduced into a vessel and subjected to a high level of isostatic pressure (300-600 MPa) transmitted by water. HPP offers several key advantages over traditional heat pasteurization:  
• it inactivates harmful bacteria and food spoilage microorganisms, resulting in longer product shelf-life; 
• it reduces the need for food preservatives; and
• retain "raw-like" attributes of the food proect with minimal effects on flavor compounds, vitamins and nutrients. 
 

Freeze Dryer
Freeze Dryer

Freeze Drying is a process by which water is removed from a food product by sublimation (i.e., allowing solid water or ice turn into water vapor). Of the different methods of dehydration, freeze drying produces a high quality food product that has a porous, non-shrunken structure that facilitates rapid and nearly complete rehydration when water is added to the freeze-dried product at a later time. 


 The goal in freeze drying is to reduce the water activity of the pet food product to a level that does not support microbial growth and minimizes chemical changes and physical deterioration, even when the product is stored at room temperatures for an extended period of time. The initial water activity, ingredients, storage conditions and packaging material properties have a combined effect on the shelf-life of a dry pet food product.
