Summary
This study analyzed Rubus sellowii, a native blackberry, revealing high acidity, protein, and ascorbic acid content. These nutritional properties suggest significant health benefits for consumers.
Area of Science:
- Agricultural Science
- Food Science
- Nutritional Science
Background:
- Rubus sellowii, commonly known as blackberry, is a native plant primarily found in Rio Grande do Sul, Brazil.
- Understanding the nutritional profile of native fruits is crucial for assessing their potential health benefits and agricultural value.
Purpose of the Study:
- To determine the physical, chemical, and nutritional characteristics of Rubus sellowii fruits.
- To compare the nutritional content of Rubus sellowii with established Rubus cultivars.
Main Methods:
- Three distinct populations of Rubus sellowii were selected for fruit analysis.
- Standard analytical methods were employed to assess moisture, ash, titratable acidity, pH, lipids, fibers, carbohydrates, proteins, carotenoids, lycopene, ascorbic acid, aminogram, and in vitro digestibility.
Main Results:
- Rubus sellowii fruits exhibited high titratable acidity (3.28%), ash (1.02%), and protein (0.93%).
- Ascorbic acid content was notably high at 38.43 mg per 100 g, exceeding that of many Rubus cultivars.
- The fruits possess a rich nutritional profile, including significant levels of carotenoids, lycopene, and essential amino acids.
Conclusions:
- Rubus sellowii fruits are a valuable source of essential nutrients and bioactive compounds.
- The high nutritional value of Rubus sellowii indicates potential health benefits and supports its consideration for wider consumption and cultivation.

25.2K
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.

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Organisms exhibit remarkable metabolic diversity, categorized based on how they acquire energy and carbon. These strategies enable survival in various ecological niches and are essential for maintaining energy flow and nutrient cycling within ecosystems.Energy and Carbon SourcesOrganisms are classified as phototrophs or chemotrophs based on energy acquisition. Phototrophs use light as their energy source, while chemotrophs rely on oxidizing chemical compounds. Further differentiation arises...

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...

The energy stored by a structure and location of matter in space is called potential energy. For instance, raising a kettlebell changes its spatial location and increases its potential energy. Similarly, a stretched rubber band contains potential energy which, under certain conditions, can be converted into other forms of energy, such as kinetic energy.
Chemical bonds that form attractive forces between atoms also contain potential energy, called chemical energy. When a chemical reaction...
