Food and Nutrition water conservation food-packing unit 1 APES

  • Traditionally, the food-processing industry has been a large water user.
  • Water is used as an ingredient, an initial and intermediate cleaning source, an efficient transportation conveyor of raw materials, and the principal agent used in sanitizing plant machinery and areas. Although water use will always be a part of the food-processing industry, it has become the principal target for pollution prevention, source reduction practices.

      The food processing industry requires a large amount of water and has been greatly affected by water pollution. This can cause harm and danger to the people who consume the food if the water is contaminated.
  • Fifty percent of the water used in the fruit and vegetable sector is for washing and rinsing. The meat processing sector has minimum requirements set by the United States Department of Agriculture (USDA) on the amount of water required to clean poultry products. Water is the primary ingredient in products for the beverage and fermentation sector, and dairies utilize water as the standard cleaning agent for process machinery.

      Half of the water used in the food industry is for rinsing and cleaning. This is to ensure the health and sanitation of the foods before they are shipped and consumed.

  • Traditionally, the food-processing industry has been a large water user. Water is used for several purposes: a principal ingredient, an initial and intermediate cleaning source, an efficient transportation conveyor of raw materials, and the principal agent used in sanitizing plant areas and machinery. Table 2 shows typical rates of water use for various food-processing sectors. An abundant and inexpensive source of water is a requirement for success in the food-processing industry. This coincides with the same need for water resources in agricultural farmland activities.

      There is a great deal of water used in the food-packing industry and is necessary for the industry to survive. This also related to the agricultural activities, which is where the ingredients are made to be packed.
  • Wastewater and solid wastes are the primary area of pollution control within the fruit and vegetable food-processing industry. Their wastewater is high in suspended solids, and organic sugars and starches and may contain residual pesticides. Solid wastes include organic materials from mechanical preparation processes, that is, rinds, seeds, and skins from raw materials. For the most part, solid waste that is not resold as animal feed is handled by conventional biological treatment or composting. The total amount of material generated is a function of the amount of raw material moved through a facility, for example, for a given weight of apples processed comes a set amount of peel and seed waste.

      Wastewater solid waste is a large cause of air pollution in the food-processing industry
  • retreatment opportunities and water conservation will continue to be principal targets for pollution prevention source reduction practices in the food-processing industry. Pretreatment options look to minimize the loss of raw materials to the food-processing waste streams. Water used in conveying materials, facility cleanup, or other noningredient uses will be reduced, which in turn will reduce the wastewater volume from food-processing facilities. Wastewater treatment will continue to be the pollution prevention treatment focus for food-processing companies. The industry will continue to implement advanced innovative techniques to lessen the environmental impact of food-processing discharge wastewaters.

      Because so much water is used and much of it becomes wastewater, the industry is trying to find new techniques to conserve water and hopefully reduce the amount of waste and pollution created by this.

  • While supplements and fortification play one role in health needs, he says that fertilizers can make seeds and grains more productive, improve the quality of nutrient uptake, and increase nutrient absorption.

      Connection to soil components from the lab. Potassium, phosphorus, and nitrogen all affect the soil and help the crops that are planted in the soil to grow strong, mature faster, and take in the necessary nutrients it needs.

  • Agriculture is constrained by land and water shortages, complex demands of the food cycle, and climate change.

      Connection with water conservation and usage. There is a water shortage so conservation techniques need to be used like drip irrigation in order for plants to get the amount of water they need and to grow up healthy so that there is a healthy food source for us to eat.

      Connection to soil. Potassium is a component in the soil that helps plants to grow strong and to help fight off disease, so perhaps more potassium and other nutrients like phosphorus and nitrogen in the soil will save the crops from disease this way there will be more healthy crops for humans to eat.
