Many of the acceptable methods of canning could cause assured losses in comestible levels and can abnormally affect the attributes and superior of the aftermath afterward processing. The newer technologies generally referred to as ‘minimal processes’, aim to aftermath safe foods that are of college comestible superior with bigger organoleptic and befitting qualities. Every new action undergoes diffuse testing to ensure the furnishings on comestible amount are absolutely evaluated.
Microwave processing is heating by radiation as against to the added acceptable alteration or advice techniques. Microwaves are transmitted calmly in baptize but not by plastics or glass, and are reflected by metals. It is cadence of the baptize molecules in aliment which leads to the heating of that food. Since the baptize is usually broadcast anyhow in a food, casual active is appropriate for able heating and safe aliment handling. Microwaving aliment is a fast adjustment of heating which requires little accession of baptize and appropriately leads to beneath comestible losses than added forms of cooking.
Processing by ionising radiation is a particular kind of energy transfer with the portion of energy transferred per treatment being high enough to cause ionisation. It is used to control and disrupt biological processes in order to extend the shelf-life of fresh products, and it can be applied to sterilise packaging materials. Beneficial biological effects of irradiation include sprouting inhibition, ripening delay and insect disinfestations. Microbiologically, irradiation suppresses pathogenic and other spoilage-causing microorganisms. The major advantage of irradiation is that it passes through the food, kills microorganisms but because it does not heat the food it has a marginal effect on the nutritional composition. Proteins and carbohydrates may be broken down to some degree but their nutritional value is little affected.
High pressure technology subjects foods to pressures of 100 – 1000 Megapascal usually for 5 – 20 minutes. It has a number of key attributes including micro-organism inactivation, modification of biopolymers such as gel formation and quality retention such as colour, flavour and nutrients. This is because of its unique ability to directly affect non-covalent bonds (such as hydrogen, ionic and hydrophobic bonds) whilst leaving covalent bonds intact, and both without employing heat. As a consequence, it offers the possibility of retaining vitamins, pigments and flavour components while inactivating microorganisms or enzymes that could otherwise negatively affect food functionality through food spoilage.
