In one incident concerning the 2016 GCSE biology exam, there were complaints about the apparent lack of biology content in the exam. [65] [66] [67] One of the questions in the biology exam asked students to define an "independent company", which some students perceived to be a business studies question. [68]
Many types of glucose tests exist and they can be used to estimate blood sugar levels at a given time or, over a longer period of time, to obtain average levels or to see how fast the body is able to normalize changed glucose levels. Eating food for example leads to elevated blood sugar levels.
Organoleptic tests are sometimes conducted to determine if food or pharmaceutical products can transfer tastes or odors to the materials and components they are packaged in. Shelf-life studies often use taste, sight, and smell (in addition to food chemistry and toxicology tests) to determine whether a food product is safe to consume.
The new combined science from CCEA since the GCSE reforms retains the same name as its predecessor. [37] The specification document presents the science curriculum in the traditional disciplines of biology, chemistry and physics. The exam is the most extensive of the GCSE science boards; made up of nine papers and three practical exams.
To undertake any analysis, unless the whole amount of food to be considered is very small so that the food can be used for testing in its entirety, it is usually necessary for a portion of it to be taken (e.g. a small quantity from a full production batch, or a portion of what is on sale in a shop) – this process is known as food sampling.
A second type of food testing strip is a gram-negative swab, which is usually administered directly to the food itself. Gram-negative swabs generally work faster than enzyme reactant strips, but they differ in that the gram-negative swabs are designed to detect a broad group of organisms, not just those that can cause foodborne illness in humans.

Food microbiology is the study of the microorganisms that inhabit, create, or contaminate food.This includes the study of microorganisms causing food spoilage; pathogens that may cause disease (especially if food is improperly cooked or stored); microbes used to produce fermented foods such as cheese, yogurt, bread, beer, and wine; and microbes with other useful roles, such as producing ...
