Continuous deep-frying operation for food - with free fatty
acid content of oil being held down by continuous filtration
and treatment with free fatty acid adsorbent
Peregrine Int Assoc
US 4913-922; 3 April 1990
Food is continuously deep fried in oil by (a) keeping a bath of
cooking oil at 350-380”F, (b) continuously adding food to the
bath and continuously removing cooked food from the bath,
(c) continuously removing from the bath a mixture of oil and
particles of larger than 170pm diameter derived from food
materials, (d) comminuting the particles to below 170pm,
(e) filtering out the particles on a pressure differential precoat
filter using a bed of finely divided material as a filter bed to
give a filter cake and particulate-free oil and (f) adding
particle-free oil, recycling (some of) the filtered oil to keep a
constant bath volume.
Production of paper packaging material, for fresh foods - is
coated with adsorbent to adsorb ethylene gas and agent to
radiate far-i.r. rays
Tsuruizumi A
JO 2106-335; 18 April 1990
A paper packaging material mainly for fresh foods has an
adsorbent for adsorbing ethylene gas and an agent for
radiating far infrared rays at ordinary temperature and
pressure coated and adhered to the surface.
Production of the paper packaging material involves paper-
making a liquid raw material, and drying to produce a paper
sheet. Prior to the drying, a mixed treating liquid of an agent
for adsorbing ethylene gas, an agent for radiating far infrared
rays, and a paste is sprayed onto the paper-made raw
material.
A filler for use in packaging with a paper material
comprises an ethylene adsorbent and a far infrared ray
radiating agent coated on the paper material.
Sterilization of container - by sterilizing wth hydrogen
peroxide and elimination of it with ferrous ion
Mitsubishi Heavy Ind KK
JO 2098-520; 10 April 1990
Sterilization of container by hydrogen peroxide and elimina-
tion of it, comprises sterilizing container with hydrogen
peroxide and treating it with ferrous ion.
Ferrous ion used, is solution of ferrous sulphate. Hydrogen
peroxide is decomposed rapidly and OH is generated by
reaction of ferrous sulphate on hydrogen peroxide. The
method comprises (1) atomizing 35% hydrogen peroxide
heated at 80°C to container, (2) supplying air of 80°C to
it to dry hydrogen peroxide and (3) atomizing wet sterilized
ferrous sulphate solution to it.
Sterile wrapping container for food - has organic polymer film
layer containing antibacterial zeolite on inside of wrapping
material

Protecting thermolabile goods with tbermosensitive tempera-
ture - by packaging with heat sink comprising salt hydrate,
hydrophilic bonding agent, and anhydrous salt and sur-
rounded by polyurethane foam
Pymah Corp
US 4903-493; 27 February 1990
Method of protecting thermolabile goods having a thcr-
mosensitive temperature from high temperatures comprises
(a) packaging the goods with a heat sink composite which has
a melting point slightly less than the thermosensitive tempera-
ture of the goods. The composite is enclosed in a container
and comprises a salt hydrate a hydrophilic bonding agent and
the same salt in anhydrous form; (b) the goods and heat sink
compound are surrounded with an insulation layer, which has
a rate of heat transfer through the layer of less than the rate of
absorbance by the sink. The container comprising (a) and (b)
is also claimed.
Packaging of perishable food products - suitable for products
susceptible of absorbing carbon dioxide
Valle Spluga Spa
EP 368-116; 16 May 1990
A method and apparatus for packaging products susceptible
of absorbing carbon dioxide. The method comprises the step
of inserting a product in a container package, the step of
sealing the package. Prior to sealing a preset amount of solid
phase carbon dioxide is introduced in the containment
package.
Detecting yeast of fungal contamination of packed liquid food
- by adding starter composite, incubating for limited time and
detecting expansion of package or change in state of product.
Univ de Dijon
FR 2624-274; 9 June 1989
Detection of yeast or fungal contamination of a liquid food
product contained in a package involves (a) addition to the
packed product of a composite favouring the growth of the
microorganisms likely to contaminate the product, (b)
incubating at 20-35°C for less than 50 h, and (c) verification
of the contamination by detecting a change in the state of the
packed product, especially expansion of the closed package,
or a change in the appearance of the product seen through a
transparent package.
Oligonucleotide(s) useful as bacterial DNA probes - useful in
diagnostics, detection of contamination etc. in pharmaceuti-
cals, food, water, etc.
