Summary
Grapefruit juice offers a rich nutrient profile, including vitamin C and flavonoids, comparable to fresh fruit. This low-calorie juice is a valuable source of essential minerals and organic acids.
Area of Science:
- Food Science
- Nutritional Biochemistry
- Public Health Nutrition
Background:
- Grapefruit juice is a popular beverage with potential health benefits.
- Understanding its nutrient composition is crucial for dietary assessments.
- Industrial production methods may influence nutrient content.
Purpose of the Study:
- To present a comprehensive nutrient profile of industrial grapefruit juice.
- To quantify key nutritive (NS) and biologically active substances (BAS).
- To compare micronutrient levels in juice with fresh grapefruit.
Main Methods:
- Analysis of published data on NS and BAS content.
- Evaluation of studies on various domestic industrial grapefruit juice samples.
- Nutrient profiling based on established analytical methods.
Main Results:
- Grapefruit juice contains over 30 NS and BAS, with low caloric content (39 kcal/100 ml).
- Rich in organic acids (citric acid: 0.8-2 g/100 ml).
- Key contributors to nutritional value include potassium, magnesium, vitamin C, and flavonoids (narigin). A glass provides ~10% DV potassium, ~6% DV magnesium, ~100% DV vitamin C, and up to 60% DV flavonoids.
Conclusions:
- Industrial grapefruit juice offers a significant source of essential micronutrients and bioactive compounds.
- Nutrient levels in commercially produced juice are comparable to those in fresh grapefruit.
- Grapefruit juice can contribute substantially to daily intake recommendations for vitamin C and flavonoids.

02:11The Roles of Bacteria and Fungi in Plant Nutrition
47.3K
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.

3.0K
Pancreatic juice is a clear fluid produced by the pancreas, containing water, salts, sodium bicarbonate, and enzymes vital for digestion in the small intestine. It helps break down large molecules, facilitating nutrient absorption.
When acidic chyme from the stomach enters the duodenum, it triggers the release of secretin, a hormone that prompts pancreatic juice secretion. After a fatty meal, cholecystokinin, another hormone, stimulates gallbladder contraction and enhances enzyme-rich...

902
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...

4.2K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
