The article provides experimental data, which help to
substantiate the effectiveness and feasibility of
application of plant resources, produced by the rubbing
of the pears in the production process of puree as raw
material for the production of secondary food additive.
For the first time, with the use of pulsed NMR it is
established that processing of secondary resources of
pears processing in UHF EMF influence on the
redistribution of bound and free moisture, i.e., the
maximum transition was for linked moisture to free
moisture, noted in the processing of secondary
resources in UHF EMF with the rate of heating
(increase in temperature) 0,4 °С/s to a temperature of
60 °С. It is established that such processing of
secondary resources of processing of pears allows to
increase the average speed of the subsequent IR-drying
and reduce the time IR drying in 2 times in comparison
with IR-drying of control sample (without
pretreatment in UHF EMF). Pre-treatment of
secondary resources of processing of pears to UHF
EMF for the identified modes allows for their
subsequent IR-drying to reduce the loss of vitamin C,
23.9% and P-active substances – by 20.6% compared
with the control sample. We have developed technological modes of production of food additives
from secondary resources of processing of pears,
providing maximum preservation in its composition of
thermolabile biologically active substances – vitamin
C and P-active substances. On the basis of these
studies, there was developed a set of technical
documentation, including TU 10.39.25-423-
040801346-2016 "Food additive. Pear Powder" and a
technological instruction for the production of food
additives
The article analyzes the existing technologies and
methods of storage of tubers of topinambur. We have
analyzed the traditional methods of storage of tubers of
topinambur - in containers, boxes or bags in storage or
in the ground clamps. Russian and foreign topinambur
tubers storage technologies in modified atmosphere,
with use of easily removable wax coating, with plant
extracts treatment, at different storage temperatures are
studied. We have also carried out analysis of scientific
and patent sources led to the conclusion that existing
technologies and methods of storing topinambur tubers,
which do not allow reducing to the maximum extent
the weight loss and the inulin hydrolysis during
storage. A reasonable conclusion was made about the
advisability of further studies in the field of innovative
technologies and methods of preparation for storage
and storage of topinambur tubers, ensuring minimal
weight loss, as well as maximum preservation in their
structure of inulin, vitamin C and other biologically
active substances during storage
The article lists the characteristic and scrutinizes features
of modern topinambur varieties. Data, characterizing
acres in crops and crop yield abroad and in Russian
Federation, are analyzed. Classification traits of
topinambur varieties, included in the state register of
selection achievements, are studied. Data on crop yield,
duration of vegetative period, composition of carbohydrate
complex, content of vitamins, macro- and microelements
are systematized. The article studies most
popular foreign topinambur varieties. The carried out
analysis of scientific sources on agrobiological properties
and chemical composition of topinambur varieties
allowed choosing varieties, which are the most promising
for industrial processing
