Summary: Wine adulteration has led to the introduction of highly
sensitive analtycal methods in the quality control of foodstuffs. One of
these is the NMR. The paper describes application of the 2H NMR technique
and the 13C NMR technique in wine analysis. These techniques make it
possible to obtain the characteristic spectra of the wines investigated
very quickly. The wine can be identified on the basis of these spectra. At
the same time a number of components which are also quality parameters can
be quantitatively detemined without destoying the sample.

Summary: Fundamental to heat transfer analysis is the first law of
thermodynamics or the energy equation, which will be the starting point for
any problem solution. In convection problems one must also use the law of
conservation of mass and Newtons second law of motion to evaluate a given
situation adequately.
In all convective heat transfer situations energy exchange occurs between
surface and adjacent fluid. The nature of the fluid flow must therefore be
understood.
Many industrial processes involve fluids or fluid mixtures and heat
transfer. Fluids and fluid mixtures behave in various complex ways and in
consequence specialized sets of operating and design rules have been
developed. One particular group of interest is that in which the effective
viscosity varies with shear rate the so-called non-Newtonian fluids are
encountered in the food processing industries.

Summary: Manufacturers point to numerous advantages that the various
extruders and cooking techniques offer over conventional cooking methods.
Because extrusion cooking is continous, as opposed to batch process, it
ensures greater consistency in product quality.The machinery itself is more
efficient because of lower energy, space and staff requirements. Extruders
allow for greater flexibility in product formulations. Cereal flakes can be
made from different cereal flours, different particle sizes or cheaper raw
materials. Experts in the industry stress that this ability to employ a
wide variety of raw materials is important for the development of new
products, especially cereals and snacks of ashort shelf-life.

Summary: The membrane market has been growing at an annual rate of
12% over the last ten years, which is three times greater than the growth
of the market for classical filter equipment forsolid-liquid separation.
The USA account for 55% of the total module and membrane production, Europe
accounts for only 20%, and Japan for about 22%.
In 1988 a total of 70 to 80% of the biotechnology costs in the USA were
accounted for by separation techniques. In 1987 a total of 31% of the
separation processes carried out were accounted for by centrifugal
techiques, which are expected to fall to only 15% by 1997. The proportion
of evaporation techniques is also expected to fall, while the proportion of
membrane separation techniques is expected to grow to over 35%, with
processes using affinity membranes covering as much as 8% by 1997.
Medical technology and potable and waste waters account for one third of
the application of membrane techniques. These are followed by the food and
beverages field.
A change in this order is expected to take place by 1995 as follows: the
food and beverage industry will come first ,followed by potable and waste
waters, medical technology and biotechnology.

Summary: Three high performance size exclusion chromatography
columns placed in series were calibrated in terms of radii of gyration(Rg)
and hydrodynamic volume (intrinsic viscosity - IV x molecular weight -M)
with a series of pullulan and dextran standards ranging in M from 853,000
to 10,000. Online detectionw as by differential refractive index (DRI) and
viscometry (DP).Two forms of universal calibration were employed to obtain
Rg, IV and M for pectin, a class of complex plant cell-wall
polysaccharides. For pectins extracted from a large number of sources, a
Mark-Houwink plot (log IV vs. log M) gave a correlation coefficient of 0.2;
whereas, a plot of log (IV) against log Rg gave a correlation coefficient
of 0.9. These results in addition to those from the analyses of several
pectins from peach fruit indicated that pectins were aggregated and highly
assimetric in shape. The scaling law exponents for pectins were affected by
both shape and state of aggregation, rather than shape alone.

Summary: Radius of gyration (size), intrinsic viscosity, molecular
weight,percentage of galacturonate and percentage of neutral sugars were
measured for chelate-soluble (CSP) and alkaline-soluble (ASP)pectins
extracted from the cell walls of melting flesh (MF) and nonmelting flesh
(NMF) peach ŠPrunus persica (L.) BatschĆ. Weight percentage of cell walls,
pectin content and firmness were measured also. Peaches were extracted at
20,21 and 22 weeks after flowering (WAF) and after various lenghts of shelf
storage at 25 C for the peaches picked at 21 WAF. Weight percentage of cell
wall sand firmness decreased markedly between the 21st and 22nd WAF;and
between the 3rd and 6th day of storage for MF peaches as compared to NMF
peaches. During these same periods, there were marked drops in the pectin
content and the uronide content for MF as compared to NMF peache. Size and
intrinsic viscosity dropped markedly for CSP of MF peaches in comparison
with NMF peaches these same periods, whereas the molecular weight of CSP
and ASP increased in MF peaches over that measured for NMF peaches. These
results suggested that alpha-D-galacturonase (E.C.3.2.1.15) was involved in
softening only in the latter stages of ripening MF peaches. Further, cell
wall polymers containing long thin pectin aggregates were destroyed,
whereas cell walls polymers containing short thick pectin aggregates
remained.

Summary: Effect of different membrane and operating conditions on
color, volatiles, sugars and acids was investigated during the
concentration of black-currant juice by hyperfiltration. The two types of
membrane affected pigment retention differently. During the concentration,
the proportion of free anthocyanines increased, while the proportion of
condensed pigments remained constant. Volatiles retention depended to a
considerable extenton the process parameters, the membrane type used, the
degree of concentration, and the operating temperature. In contrast to the
retention of the volatiles, the retention of sugars and total acids was
almost completely independent of the operating conditions. The retention of
sugars was very good with both types of membrane.

Summary: High performance size exclusion chromatography revealed
that alkaline-extracted peach fruit pectin dissolved in 0.05M NaNO3
comprised a hierarchy of at least four aggregated, macromolecular-size
species. Each of the three largest species was found to be comparable in
length to the three smallest subunits of an interconnecting gel network
visualised by transmission electron microscopy of pectin, rapidly dried
from solution. The interconnecting subunits of the gel network were rods of
segmented rods and the integrated network formed a circular gel about 1um
in diameter. Shadowed samples prepared from 5 and 50 mM NaCl or aqueous
glycerol solutions produced images of partially dissociated subunits.

Summary: A complete understanding of the effect of dissolved pectins
on the quality of fruit juices has been limited by inability to fully
characterize pectins in solution. Recently a method was developed that uses
high perfomance size exclusion chromatography(HPSEC) with concentration and
viscosity detection to obtain the radius of gyration, (Rg), the intrinsic
viscosity, and the molecular weight (MW) of pectin. Ultrafiltration (UF) of
pectin was investigated in order to determine conditions under which pectin
could be either concentrated or fractionated. Removal of small MW material
by UF has the potential of increasing both the weight average MW and the
viscosity of material in the retentate. UF offers industry a method for
purifying pectin and for controlling critical functional properties of
pectin, such a sviscosity and ability to gel. Commercial citrus pectin and
lime pectin were treated by plate module ultrafiltration (PMF) (1).
Commercial citrus and apple pectins were treated by hollow fiber
ultrafiltration (HFF) (2). The pectin in the retentates was subjected to
HPSEC and the chromatograms were analyzed in terms of narrow Rg MW
distribution components to determine changes in Rg, MW and viscosity (3-5)

Summary: The paper deals with an alternative procedure for reducing
the amount of the heavy metals in wine. The procedure is based on the
complex-binding properties of popcorn-polymeres based on
1-vinylpyrrolidone. The active group in this compound is the imydasole
ring. The mechanism of activity is based not on the ion-exchanger mechanism
but in the donor-acceptor bond between the heterocycic ring with nytrogen
and the heavy metal catione.The action of various popcorn-polymeres with a
growing share of imydasole was investigated. The results show that the new
popcorn-polymere preparation is fully acceptable as an alternative to blue
fining. It is highly selective and effective and at the same time avoids
the problem of cyanide both in application and waste disposal.

Meeting: New Developments in Filtration and Separation in the Beverage Industry, International Symposium.
Held: from 03/23/94 to 03/25/94
Summary: Cross-flow filtration is a well-known separation process in
food and beverage technology. This process has been of interest for
industry for the last 30 years. One of the cross-flow techniques is
ultrafiltration. This is a membrane process which is being increasingly
used not only in the processing of diary products, but also in the various
stages of fruit juice and wine technology as a substitute for the
conventional filtration/clarification procedure. Due to the rapid
development of membranes(with regard to the kind of material and
structure), such a clarification process does not cause any change in the
colour and bouquet of wines. The objective of this investigation was to
study the comparative advantages(as regards wine quality) of various
procedures of cross-flow filtration compared to the classical (dead end)
filtration. Furthermore, the importance of removing the concentrate by the
batch, semi-batch and continuous ultrafiltration procedures for the
capacity of filtration was investigated.

Summary: Reverse osmosis is a process where water is removed from a
solution combining dissolved matter to be concentrated. Over the past few
years this process has found an increasing applicationin fruit juice and
concentrate technology as an alternative to traditional processes as
concentration by evaporation, especially when some disadvantages of
traditional processes have to be avoided (in this case influence of
temperature).
The objective of this research was to investigate the behaviour,i.e. the
passage into the permeate of various metals and non-metals and the
retention of volatiles during quince juice concentration by reverse osmosis
in a DDS LAB 20-module UF-RO system using two membrane types at two
operating temperatures and an operating pressure of 50(60) bar.
The increase in the permeability of the selected membranes for the elements
investigated was not the same for the total soluble dry solids, but varied
depending on the nature of the elements. Generally, the increase in the
permeability of the membranes for the elements investigated was an inverse
function of their atomic mass, which was to be expected. Although the
fraction in the permeate was not great in absolute values, it increased as
the degree of concentration of the juice increased , but not to the same
extent as was the case within the total soluble dry solids.
The temperature and the degree of concentration influenced the permeability
of the membrane for the soluble total solids and for metals and non-metals.
The passage of these substances from the juice into the permeate increased
with increasing temperature and degree of concentration.

Summary: The properties of fruit juices are determined to a great
extentby the composition and mutual interrelationship of
non-volatileorganic acids. This research involved developing a method
thatwould make possible the simoultaneous determination of the
majornon-volatile organic acids in fruit juices. The investigationswere
carried out on concentrated lemon, orange, pineapple, plumand sour cherry
juices. Measurments were made using gaschromatography. The results show
that the method suggested can beused very successfully to determine the
non-volatile organicacids in fruit juices. Due to its simplicity, it could
bedeveloped further and proposed as the standard technique fordetermining
one of the quality parameters of non alcoholicbeverages.

Summary: Wine contains valuable mineral substances and trace
elements in avery favourable form. However, large concentrations of
someelements in wine,particularly iron and copper,may effect thehealth of
consumers,as well as having a negative effect on thetechnological process
of wine making. In thisresearch,investigations were carried out with a new
syntheticsubstance,polyvinilimidazol (PVI),which has the ability
toselectively remove particular metals. The results show that PVIhas higly
effective in removing copper and iron, but was not soeffective in removing
zinc and manganese. The results indicatethat PVI can be used successfully
as a substitute for potassiumhexacyanoferrate(II) for wine clarification.

Summary: Research was carried out on the influence of various
methods ofcarrying out the filtration process on the filtration capacityand
the quality of white wine. These methods included batch,semi-batch and
continous filtration, as well as clasicallfiltration. A high quality white
wine was used on a commercialscale. Better colloid separation from wine was
achieved usingultrafiltration compared to clasicall filtration. The
greatestfiltration capacity was achieved by the batch method, followed
bythe semi-batch and continuous methods.

Summary: The goal of this research was to find a simple method for
the production of wines enriched with procyanidins. Experiments were
carried on the red grape cultivar Vranac in the years 1990,1991,1992. The
wines were produced from crushed grapes by the process of: T.F.-traditional
vinification (the pomace contact was five days long) and M.F.-modified
vinification (includes a maceration with a greater share of solid phase).
Low molecular flavans were determined by high pressure liquid
chromatography (HPLC) on reverse phase using gradient elution. Previous
Fractionation of acidic and neutral phenolic compounds on Sep pak C18
cartridges was carried out. The results obtained showed differences in the
amounts of (+)-catehin, (-)-epicatehin and procyanidin dimers B1, B2, B3
and B4 in the wines produced by traditional and modified vinification. The
positive effect of an extended period of maceration was also noticed. The
process of modified vinification is very simple and according to the
results obtained, makes possible the production ofwines which can be
considered physiologically, from grape moderately rich with procyadins.

Number of pages: 112
Summary:
The aim of the research was to investigate the influence ofvarious methods
of carrying out the filtration process on thecapacity and yield of white
wine. The methods which were used inthe research were the batch, semibatch
and continuousultyrafiltration methods, as well as the classical
filtrationmethod.
The research was carried out on Laški Rieslig 89, a fine whitewine of
controlled origin, on commercial scale. Theultrafiltration process was
carried out on a DDS pilot modulewith built-in fluorpolymer membranes known
as FS 40 PP with apoor diameter of 100.000 Daltons.
The classical filtration process was carried out on a verticalplate filter.
The results of the research indicate that the batch, semibatchand
continuous ultrafiltration methods may be used successfullyto clarify white
wines, both with regard to the efficiency of thepilot equipment used and
with regard to the sensory properties ofthe wine.
