Intermediate moisture foods (IMF) are shelf-stable products that have water activities of 0.6-0.85, with a moisture content ranging from 15% - 40% and are edible without rehydration. [1] These food products are below the minimum water activity for most bacteria (0.90), but are susceptible to yeast and mold growth .
When considering food storage and preservation, the technologies of modified atmosphere and controlled atmosphere are widely used for the storage and packing of several types of foods. They offer several advantages such as delay of ripening and senescence of horticultural commodities, control of some biological processes such as rancidity ...
The process can be categorized based on the type of solar energy source utilized. In direct solar desalination, saline water absorbs solar energy and evaporates, leaving behind salt and other impurities. An example of this is solar stills, where an enclosed environment allows for the collection and condensation of pure water vapor.
In a single-stage digestion system (one-stage), all of the biological reactions occur within a single, sealed reactor or holding tank. Using a single stage reduces construction costs, but results in less control of the reactions occurring within the system. Acidogenic bacteria, through the production of acids, reduce the pH of the tank.
Equipment used in aseptic processing of food and beverages must be sterilized before processing and remain sterile during processing. [1] When designing aseptic processing equipment there are six basic requirements to consider: the equipment must have the capability of being cleaned thoroughly, it must be able to be sterilized with steam, chemicals, or high-temperature water, sterilization ...
A food storage calculator can be used to help determine how much of these staple foods a person would need to store in order to sustain life for one full year. In addition to storing the basic food items many people choose to supplement their food storage with frozen or preserved garden-grown fruits and vegetables and freeze-dried or canned ...
Food prices in the U.S. rose nearly 11% from 2021 to 2022, the largest year-to-year increase in more than 40 years. Although food inflation has somewhat leveled off at nearly 4% in 2023, many...
There are many water purifiers available in the market which use different techniques like boiling, filtration, distillation, chlorination, sedimentation and oxidation. Currently nanotechnology plays a vital role in water purification techniques. Nanotechnology is the process of manipulating atoms on a nanoscale. [1]
