Spent coffee grounds

Coffee grounds are the residues left in the filter or in the cloth sleeve used to brew coffe

It has been proven that this by-product can have multiple applications:agronomic, gastronomic, artistic, among other.s

The First Methods

Food processing dates back to prehistoric ages, with crude processing methods that included slaughtering, fermenting, sun drying, preserving with salt, and various means of cooking (such as roasting, smoking, steaming, and oven baking). Salt-preservation was especially common for foods that constituted the diets of warriors and sailors, up until the introduction of canning methods

Concern and Changes

The history of food processing has grown more in the last 200 years than it has throughout the tens of thousands of years that human civilization has existed. As these processes continue to advance, foods that are safe, accessible, and affordable as well healthy and environmentally-friendly are the next challenges to meet.

Meal, Ready to Eat

World War II, the space race, and the rising consumer society in developed countries (including the United States) contributed to the growth of food processing with such advances as spray drying, juice concentrates, freeze drying, and the introduction of artificial sweeteners, coloring agents, and preservatives such as sodium benzoate.

• Spray drying
• evaporation
• freeze drying
• use of preservatives

Made it easier to package different types of foods and keep them on the shelf. Artificial sweeteners and colors helped to make these preserved foods more palatable. The home oven, microwave, blender, and other appliances provided an easy way to quickly prepare these meals. Factories and mass production techniques made it possible to quickly produce and package foods.

• Dried Instant soups
• Reconstituted fruits and juices
• Self-cooking meals

FIRE

Heat

Homo erectus invented different methods to provoke fire (the first "lighters"), either with sparks produced by rubbing stones, wood or other techniques. This allowed them not to depend on natural phenomena or the generosity of other tribes to achieve it.

Pasteurization and Canning

• Pasteurization, developed by and named for French microbiologist Louis Pasteur, was researched in the 1860’s. This process was particularly important for juices especially milk, which is very susceptible to bacterial growth. Pasteurization kills microbes by applying heat, without affecting the nutritional quality or taste of the food. Without this process, the history of food processing would not have advanced much further. Long-term food storage and transport throughout the world would have been extremely limited.

• A bit earlier around 1810, a French chef was working with a similar process. Nicolas Appert began experimenting with food preservation using heat, glass bottles, cork and wax. La Maison Appert (The House of Appert) became the first food-bottling factory in the world.

How to use it:

1. Collect the spent coffee grounds
2. Dying: Spread the coffee grounds in a thin layer on trays, you can use a food dehydrator to speed upt the process
3. Storage: It has to be in containers in a cool, dark place

Why it can be useful:

• Moisture Removal: Coffee grounds removes moisture
• Extended Shelf Life: It have a longer shelf life compared to moist grounds

• "Coffe flour", it can be used as a gluten-free and nutrient-rich ingredient in baking
