135 330653u Absorption of Maillard reaction
volatiles by polymers. Bressa, Francesca Steel,
Robert J Dalla Rosa, Marco (Dipartimento di
Scienze degli Alimenti, University of Udine,
33100 Udine, Italy). Packag. Technol. Sci 1996,
9(5), 255-263 (Eng), Wiley. Correction of CA 126
5904p. The antioxidant properties of Maillard
reaction volatilities (MRV) have been
demonstrated in previous studies in particular a
significant antioxidant activity of MRV on the
oxidn. of heat-treated soybean oil was found.
These findings offer an opportunity to use MRV to
protect foods susceptible to oxidative
deterioration. . . . . .

TIP for subject or substance name search

• Avoid temptation to look directly in -
• General Subject or Chemical Substance
• Index
• Look in Index Guide first
• The Index Guide will point you to
• the preferred / current subject or
• chemical substance
• cross-references for any new /
• alternative name/s
• Use preferred terms to look in General
• Subject or Chemical Substance Index

FORMULA SEARCH

• FORMULA INDEX quickest route
• Have the formula in Hill System Order
• Inorganic alphabetically by element symbols
• Organic C first, H (if present) then remaining
  symbols in alphabetical order

26
FORMULA SEARCH

• Identify formula eg
• C3H2Cl6N2P2
• Decide year range to search eg 1978
• Look up your formula in the relevant Formula
  Index eg vols 88/89

27
FORMULA SEARCH-FORMULA INDEX

• Look up the formula

TIP for formula search

• Formula Index can be used directly to locate
• abstract numbers but . . . .
• An additional search in Chemical Substance Index
  (using name found in Formula Index) will find
  papers on related substances not found in Formula

31
AUTHOR SEARCH

• Identify authors
• eg Kevin L Ash
• Decide year range to search eg 2001
• Look up your surname in the relevant Author Index
  for those years eg vols 134/135

GENERAL TIPS

• If searching 1907-1976, unless you want to search
  for a specific year, use collective indexes
• Start with most recent index and work back
• Read the introduction to each index

34
GENERAL TIPS

• Use INDEX GUIDE as a first step in General
  Subject or Chemical Substance searching
• Chemical names change from volume to volume but
  CA Registry Number remains constant. Try
  searching using this.
