spongiform encephalopathy Progressive degenerative neurological diseases including scrapie (in sheep), bovine spongiform encephalopathy (BSE, in cattle) and Creutzfeldt-Jakob disease (in human beings). Believed to be caused by prions. BSE is believed to originate from infected meat and bone meal in cattle feed concentrates, and early onset Creutzfeldt-Jakob disease (new variant or nvCJD) has been linked to consumption of beef from animals affected by BSE.

A ban on specified bovine offal in food and feedstuffs, a ban on sale of meat from cattle more than 30 months old (reducing to 24 months in 2005) and a policy of slaughtering affected animals have resulted in a dramatic fall in the number of confirmed cases of BSE. The important unknown factor is the incubation period in human beings. spores Bacterial spores are a resting state, resistant to heat, which can germinate to produce bacteria under suitable conditions. Spore formation only occurs in some species, when the organism encounters adverse conditions (e.g. dryness, lack of nutrients).

Spore-forming species, especially of Bacillus and Clostridium, are a health hazard because the spores are resistant to most sterilisation techniques. sports drinks Solutions of glucose plus electrolytes to mimic those lost in sweat; generally isotonic with blood plasma to avoid potential problems of water intoxication.

Staphylococcus aureus Food poisoning organism that produces enterotoxins (TX 1.2.3.1-7) in the food. Onset of symptoms 1-6h, duration 8-24h.

starch A polysaccharide, a polymer of glucose units; the form in which carbohydrate is stored in the plant (glycogen is sometimes referred to as animal starch.) Starch is broken down by acid or enzymic hydrolysis (amylase), ultimately yielding glucose; it is the principal carbohydrate of the diet and, hence, the major source of energy for human beings and animals.

Starches from different sources (e.g. potato, maize, cereal, arrowroot, sago) have different structures, and contain different proportions of two major forms: amylose, which is a linear polymer and amylopectin, which has a branched structure. The mixture of dietary starches consists of about 25% amylose and 75% amylopectin.

starch, modified Starch altered by physical or chemical treatment to give special properties of value in food processing, e.g. change in gel strength, flow properties, colour, clarity, stability of the paste.

Acid-modified starch (thin boiling starch): acid treatment reduces the viscosity of the paste (used in sugar confectionery, e.g. gum drops, jelly beans).

Cross-linked starch: chains are cross-linked by phosphate or adipic diesters, to strengthen the granule and so control texture and provide heat, acid, and shear tolerance.

Derivatised starch (or stabilised starch): chemical derivatives such as ethers and esters show properties such as reduced gelatinisation in hot water and greater stability to acids and alkalis (inhibited starch); useful where food has to withstand heat treatment, as in canning or in acid foods. Further degrees of treatment can result in starch being unaffected by boiling water and losing its gel-forming properties.

Oxidised starch: peroxide, permanganate, chlorine, etc., alter the viscosity, clarity and stability of the paste (major use is outside the food industry).

See also starch, pregelatinised.

starch, oxidized See starch, modified.

starch, pregelatinised Raw starch does not form a paste with cold water and therefore requires cooking if it is to be used as a thickening agent. Pregelatinised starch, mostly maize starch, has been cooked and dried. Used in instant puddings, pie fillings, soup mixes, salad dressings, sugar confectionery, as binder in meat products.

starch, resistant Starch that escapes digestion in the small intestine but can be fermented in the colon. Depending on the analytical method, resistant starch may be included with dietary fibre. Chemically it is a glucan formed when starch is heated (apparently formed after gelatinisation by spontaneous self-association of hydrated amylose).
