Frozen vs Fresh - A Question of Nutrition

Frozen vegetables are undeniably handy – they are relatively inexpensive, require minimal preparation, last for ages in the freezer, and can be prepared in minutes. Often added to a meal as a guilty afterthought, frozen vegetables help to ease the conscience of a working mom or busy singleton. Any form of vegetables would be better than no vegetables at all, but are we sacrificing
nutrition for the sake of convenience...

Cell Rupture: Detergents vs Traditional Physical Methods

Detergents (surfactants) are used in cell lysis solutions because they disrupt the distinct interface between hydrophobic and hydrophilic systems. They help to solubilize membrane proteins and lipids, thereby causing the cell to lyse and release its contents. Detergents are comprised of a polar hydrophilic head group and a nonpolar hydrophobic tail. They are categorized by the nature of the head group as either ionic, nonionic or zwitterionic.

Probiotics

The intestinal tract is home to trillions of bacteria that can have a huge impact on overall pet health. An imbalance in bacterial populations can affect the body’s immune system, lead to digestive disorders, inflammation of the intestines or diarrhea. The gut microbiota can even affect brain development and behavior. Probiotics are live bacteria that can help
to shift gut microbiota toward more beneficial bacterial
species, helping maintain an optimal balance

Chemical Methods of Cell Disruption

Cell disruption, or cell lysis, is achieved when the cell wall or membrane is ruptured, releasing the contents of the cell. Cell disruption is the first step in many biotechnology applications. This sensitive process needs to be controlled as much as possible; and choosing the correct cell lysis method is essential for preserving the desired intracellular contents.

Cell disruption can be achieved in several ways, including mechanical, enzymatic or chemical lysis.

Why Scalability Matters for Particle Size Reduction Equipment

Process manufacturing is the branch of manufacturing associated with ingredients or raw materials, formulas, and manufacturing recipes. This kind of manufacturing is common in the food, beverage, chemical, pharmaceutical, consumer packaged goods, and biotechnology industries. Scalability is a crucial element in process manufacturing, as production processes must be proportionally adjustable to adapt to production needs.

Types of Emulsifiers & How High Pressure Homogenization Creates Stable Emulsions

An emulsifier (or an emulgent) is a substance that essentially helps in the formation and stabilization of an emulsion. Emulsifiers are surface-active agents that act as the interface between the two immiscible liquids, like oil and water. Emulsifier molecules have a hydrophilic end that forms chemical bonds with water but not with oils; and a hydrophobic end that forms chemical bonds with oils but not with water.

AIM Mag-nificence: Miracle Magnesium

Magnesium is important in more than 300 chemical reactions occuring within the human body. This essential element helps to maintain normal nerve and muscle function, supports a healthy immune system, keeps the heartbeat steady, and helps bones remain strong. It also helps regulate blood glucose levels and aids in the production of energy and protein. In the stomach, magnesium helps neutralize stomach acid and
moves stools through the intestine.

How Homogenization Benefits Emulsions in the Food Industry

An emulsion is a mixture of two immiscible liquids (like oil and water), where small droplets of one liquid are dispersed throughout the second liquid. Emulsions can be classified as follows: Oil in water emulsion – where oil droplets are dispersed in the water phase e.g. homogenized milk or a “creamy” style salad dressing. Water in oil emulsion – where water droplets are dispersed in an oil phase e.g. margarine.

French Press Cell Lysis: How Does It Compare to Homogenization?

The French pressure cell press, or French press, is a piece of equipment used in laboratories to disrupt cell walls and cell membranes. The French press consists of a hydraulic pump that drives a piston. The piston forces the liquid sample through a tiny valve under high pressure. As the sample passes through the valve, the cells experience shear stress, resulting in cellular disruption...

Understanding Blood Pressure

Blood pressure is the force of circulating blood pushing against the blood vessel walls. It is one of the principal vital signs measured by health care professionals in order to assess our general state of health. Blood pressure is measured in units called millimetres of Mercury (mm Hg). Systolic pressure (the top number) represents
the pressure in our arteries as the heart contracts and moves blood into the circulation. Diastolic pressure (the bottom number) occurs as the heart relaxes; it is the
minimum pressure to which the arteries are
exposed.
Low beats high
Current guidelines identify normal
blood pressure as lower than 120/80
(systolic/diastolic). High blood pressure,

Explaining Type II Diabetes

Diabetes mellitus is a group of metabolic diseases characterized by elevated blood glucose levels. These high levels are from defects in either insulin secretion, insulin action, or both. Essentially, diabetes is caused by a problem in either the way your body makes insulin or the way it uses insulin. Read on to learn more about the basics of blood sugar levels and insulin, as well as what can go wrong and how to manage it.
