Protecting
Perishables From Package pests
|
|
Insect pests often invade
and pen�etrate packaged foods somewhere along the marketing
chain, mostly during trans�portation and storage. As an
alternative to traditional insecticides, the united states
agricultural research service en�tomologist mr. Franklin
Arthur at the Grain Marketing and Production Re�search
Centre in Manhattan is conduct�ing studies with insect
growth regula�tors (igrs) that prevent insect larvae from
becoming reproductive adults.
To replicate food storage
condi�tions, Mr. Arthur has created miniature "exposure
arenas" by pouring concrete into petri dishes. Once/the
concrete hard�ens, igrs are sprayed directly onto the
concrete and the insects exposed to the treated concrete.
Since igrs are not nor�mal ly toxic to humans, they can
be used to banish pests of packaged foods such as the
red flour beetle and the confused flour beetle. Mr. Arthur
evaluated the effect a volatile formulation of hydroprene,
an igr, has on the pests. Larvae of both beetle species
often failed to moult to the adult stage. Of the insects
that made it past the stunted-growth hurdle, most were
deformed and died soon after. The study assumes signifi�cance
in the light of increased restric�tions of the use of
pesticides. Contact: Ms. Rosalie Bliss, United States

New
Technology Extends Shelf-life of Agri Products |
|
Maxtendtm system is a new
tech�nique developed by a team at Queens�land Department
of Primary Industries, Australia, to help extend the shelf-life
of Fruits and vegetables. This system con�verts a standard
refrigerated container into one with a modified atmosphere.
The lightweight and cost-effective unit fea�tures complete
monitoring, adjustment and control of the optimum atmosphere
for fresh produce storage. It can also provide a log of
the container's journey. MAXtend allows producers to maximize
the storage life of their fresh produce and thereby reach
new markets that were pre�viously excluded because of
time or dis�tance. It can tailor the atmosphere to suit
specific products and also produces less moisture loss,
thus resulting in firmer, fresher fruit with less wilt.

yoghurt alleviates diabetes |
|
Skanemejerier, a Swedish
com�pany, has recently introduced a yo�ghurt that contains
beta glucans, which help in maintaining an even blood
sugar and insulin level and also have a cho�lesterol-lowering
effect. The yoghurt consists of 200 ml vanilla or natural
flavour low-fat yoghurt and muesli containing 4 g of beta
glucans, the water-soluble, gel-forming dietary fi�bres
derived from oats.
Test results have shown that
among people who had the new yo�ghurt, blood sugar increase
was 35.5 percent and insulin response was 43.7 percent
compared with those who did not have yoghurt in their
meal.contact: skanemejerior ek. For. 205 03 maimo, sweden.
