How Does Engineering Take Part in Food Processing?
Food processing engineering is used to process, preserve, and store food from raw to finished products. The aim of this is to improve food quality for customers to consume the final product. The presence of technology plays a major role in speeding up or advancing the whole process. Important factors considered here include safety, quality, nutrition, food development, ingredients, and chemical reactions. Food engineering includes production, processing, packaging, handling, storage, control, conservation, and end product distribution.
Freezing food products in the refrigerator is one way that appears in the food processing engineering lane. Technology has established a primary method of storing food for a longer period. The main purpose of refrigerators is to preserve food quality and safety measures. Some foods cannot be left open for an extended time, and they need more storage attention. Vegetables, fruits, fish, dairy products, or meat need to be stored under cool conditions. This act maintains appearance, the food quality, flavor, or taste for consumers to enjoy and stay healthy. That form of storage will reduce at which bacteria that grow.
Packaging food products before delivering them to the public is important. The technology used to ensure proper packaging considers several factors. It elongates shelf life, keeps the food clean for stabilization, and looks attractive to the consumers. For example, if you were to select food packaged in a jar or an open carton box, which one are you most likely to pick? People will consider several factors, including the physical appearance or its durability, before purchasing the product.
Canned food is more protected and appealing for purchase at any time. It can also be stored for a longer period than the one that comes in a carton box. Food engineering considers materials that are not harmful to the environment. Paper materials, compostable plastics, plastics from corns, or recycled materials are used for packaging food. That step will be eco-friendly and attract more attention to clients who are keen on their surroundings. This saves you from frequent visits to the store and comes in handy when you want to prepare quick meals for visitors. It is money-saving because you buy canned food a few times a month that will last longer without going bad.
For food processing to take place, energy is needed to make it happen while increasing food sustainability. Technology has developed better ways to source energy from non-thermal heating as well as thermodynamic cycles. The method will save on energy consumption as it cuts down on costs. The durability elements will be considered when processing food, extending the consumption period for use in the future.
Ever asked yourself how food engineering participates in ensuring the growth of molds does not happen? Evaporation is the answer that you are looking for. All it does is cut down water level, adjust food color, or get more solid than liquid food content. This is how the sauce, coffee, milk, sugar, fruit juice, or seasonings are made. By dehydrating these types of food, molds have nowhere to live as they grow on moist surfaces. Sugar is always dry, for all the water content has been drained through evaporation to be in its current state. The same thing applies to coffee, and when you buy it packed in sachets, it is always dry.
The transfer of heat during food processing is used by food engineers. Almost every food product that is commercialized is processed by the heat transfer method. These heat transfer methods include convection, induction, and radiation that make variations in the physical appearance of food while baking, freezing, or deep-frying. While they preserve hygiene and nutrition, they provide an opportunity for food engineers to be more innovative in transforming food products.
Food processing engineers are required to design a process and develop equipment to generate new items. This process involves both production, processing, distribution, and storage from raw to finished goods. They start with raw materials, from the very beginning to end with the packaging of finished goods. Food engineers are obligated to comprehend both the chemical and physical properties of every food, which will lead to the innovative creation of better designs.
