Key Elements for Plant Nutrition

Key Elements for Plant Nutrition

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Plant Breeding and Biotechnology

Plant Breeding and Biotechnology

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Optimal Foraging

Optimal Foraging

How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

Introduction to Carbohydrates

Introduction to Carbohydrates

Carbohydrates, proteins, and fats are the primary macronutrients in the human diet. However, carbohydrates are the most favored source of energy in the body. They can be found in a wide variety of foods, including whole grains, fruit, and vegetables, in various forms, such as sugars, starch, and dietary fiber. Based on their structure, carbohydrates are classified into three main classes— monosaccharides, disaccharides, and polysaccharides. The body's cells can only utilize simple...

Transgenic Plants

Transgenic Plants

Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Fruit Development, Structure, and Function

Fruit Development, Structure, and Function

Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

Background:

Tiger nuts (Cyperus esculentus L.) are tubers rich in lipids, protein, starch, fiber, vitamins, minerals, and bioactive factors.
They possess significant nutritional value and have been traditionally used for food and feed.
Recent research indicates potential medical properties, including radical scavenging and anti-inflammatory effects.

Purpose of the Study:

To systematically review the nutritional composition of tiger nuts.
To explore various processing methods for extracting edible components like oil, starch, and protein.
To assess the physiochemical properties, functional characteristics, and food industry applications of tiger nut components.

Main Methods:

Literature review of existing studies on tiger nut composition, processing, and applications.
Analysis of different extraction techniques, including mechanical compression, alkaline methods, and alkali extraction-acid precipitation.
Evaluation of physiochemical and functional properties influenced by extraction methods.

Main Results:

Mechanical compression, alkaline methods, and alkali extraction-acid precipitation are identified as suitable methods for oil, starch, and protein extraction, respectively.
Extraction methods significantly impact the functional and nutritional properties of tiger nut components.
Tiger nuts exhibit antioxidant, anti-inflammatory, and anti-apoptotic properties, suggesting therapeutic potential.

Conclusions:

Comprehensive utilization of tiger nut nutrients requires combining traditional extraction methods with innovative techniques to enhance yield and physiochemical characteristics.
Tiger nut-derived products like milk, snacks, beverages, and gluten-free bread are already established.
Further research is needed to fully exploit tiger nuts' functional properties, explore modifications, and optimize processing for industrial-scale production.
